The objective of the current study was to determine the incidence of contamination by the top 7 Shiga toxin-producing Escherichia coli (STEC) O-groups, responsible for the majority of E. coli infections in human beings, in retail meat from different animal species. Samples from ground beef (n = 51), ground pork (n = 16), ground chicken (n = 16), and game meat (deer, wild boar, bison, and rabbit; n = 55) were collected from retail vendors for the detection of 7 STEC O-groups (O26, O45, O103, O111, O121, O145, and O157). Meat samples were tested by using a multiplex polymerase chain reaction assay targeting the wzx gene of O antigen gene clusters of the 7 STEC O-groups. The positive samples were further tested for Shiga toxin genes (stx1 and stx2). Out of a total of 83 ground beef, pork, and chicken samples, 17 (20%) carried O121, 9 (10%) carried O45, 8 (9%) carried O157, 3 (3%) carried O103, and 1 (1%) carried O145. None of the samples were positive for O26, O111, or the stx gene. All 3 white-tailed deer samples (100%) were positive for O45, O103, or both, 2 (10%) out of 20 red deer samples exhibited the presence of O103, and all 3 bison samples were contaminated with either O121, O145, or O157. One sample from ground deer, contaminated with E. coli O45, carried the stx1 gene. This preliminary investigation illustrates the importance of microbiological testing of pathogens in meat products, as well as the recognized need for increased surveillance and research on foodborne pathogens.

Extended-spectrum β-lactamases (ESBLs)-producing Salmonella is considered a serious concern to public health worldwide. However, limited information is available on ESBLs-producing Salmonella in retail chicken products in China. The objective of this study was to characterize ESBLs-producing Salmonella isolates from retail chickens in China. A total of 890 Salmonella isolates from retail chicken carcasses collected from 4 provinces were firstly screened for ESBLs-production phenotype via the double-disk synergy test method. A total of 96 (10.8%, n=890) ESBLs-producing Salmonella were identified and subjected to PFGE analysis, characterization for the presence of ESBLs encoding genes, transposons, carbapenemase and virulence genes. A total of 59 PFGE profiles were detected in these 96 isolates, among which 57.3% were found to harbor bla TEM-1 , whereas 30.2%, 24.0%, 18.8% and 7.3% were carrying bla OXA-1 , bla CTX-M-15 , bla CTX-M-3 and bla PSE-1 genes, respectively. Moreover, 42 (43.8%) isolates co-carried 2 ESBLs-producing genes, and two (2.1%) isolates co-carried 3 genes. Furthermore, 24 (25.0%) ESBLs-producing isolates carried VIM and 10 (10.4%) carried KPC encoding genes that closely associated with carbapenems resistance. Eighty-eight isolates harbored transposons ranging from 4.2% for Tn903 to 76.0% for Tn21. Out of the 88 Salmonella that harbored transposons, 25%, 22.7%, 23.9%, 10.2% and 1.1% of isolates were found to carry 2, 3, 4, 5 and 6 transposons, respectively. The minimum inhibitory concentration (MIC) values for cephalosporins (ceftriaxone, cefoperazone and cefoxitin) to ESBLs-producing isolates were from 4 to 1024μg/mL, for nalidixic acid were from 64 to 512μg/mL, for fluoroquinolones (ciprofloxacin, levofloxacin and gatifloxacin) were from 4 to 256μg/mL. Twenty-nine virulence genes were detected in the 96 ESBLs-producing isolates with 2.1% harbored spvR (lowest) and 90.6% harbored marT and steB (highest). All isolates carried at least one

This study examined the prevalence, counts, and subtypes of Campylobacter, Salmonella, Listeria monocytogenes, verotoxigenic Escherichia coli (VTEC), and E. coli on raw retail chicken breast with the skin on versus the skin off. From January to December 2007, 187 raw skin-on chicken breasts and 131 skin-off chicken breasts were collected from randomly selected retail grocery stores in the Region of Waterloo, Ontario, Canada. Campylobacter isolates were recovered from a higher proportion of the skin-off chicken breasts, 55 (42%) of 131, than of the skin-on chicken breasts tested, 55 (29%) of 187 (P = 0.023). There was no difference in the proportion of Salmonella isolates recovered from the two meat types (P = 0.715): 40 (31%) of 131 skin-off chicken breasts versus 61 (33%) of 187 skin-on chicken breasts. L. monocytogenes isolates were recovered from a statistically lower proportion of the skin-off chicken breasts, 15 (15%) of 99, than of the skin-on chicken breasts, 64 (34%) of 187 (P = 0.001). There was no difference in the proportion of E. coli isolates recovered from the skin-off chicken breasts, 33 (33%) of 99, than from the skin-on chicken breasts, 77 (41%) of 187 (P = 0.204). VTEC was detected on a single skin-off chicken breast. Campylobacter jejuni was the most frequent species isolated on both types of chicken meat: skin-on, 48 (87%) of 55, and skin-off, 51 (94%) of 54. Salmonella serotypes Kentucky and Heidelberg and L. monocytogenes serotype 1/2a were the most frequently detected serotypes from both skin-off and skin-on chicken breasts. Although there appeared to be a trend toward higher enumeration values of these pathogens and E. coli on the skin-on chicken, the differences did not exceed 1 log. This study suggested that skin-off chicken breast may represent a higher risk of consumer exposure to Campylobacter, a similar risk for Salmonella, VTEC, and E. coli, and a lower risk for L. monocytogenes than skin-on chicken breast.

In 2007 and 2008, a monitoring study was carried out in Poland to examine the occurrence of thermotolerant Campylobacter spp. in raw and cooked chicken products available on the retail market. A total of 912 samples were tested: 443 samples of raw chicken meat, 146 samples of giblets, and 323 ready-to-eat poultry products (150 samples of spit-roasted chicken, 56 samples of smoked chicken, and 117 samples of pâté and cold meats). A high level of contamination of raw chicken meat (51.7% of samples) and chicken giblets (47.3% of samples) was detected. However, thermotolerant Campylobacter spp. were found in only 1.2% of the ready-to-eat poultry products.

The objectives of this study were, to find the prevalence and antimicrobial resistance of L. monocytogenes from a total of 116 chicken meat samples including 50 carcasses and 66 meat parts marketed in Turkey between 2008 and 2009 using immunomagnetic separation (IMS) based cultivation technique, to detect the hlyA gene for the verification of the isolates by PCR, and to identify the genoserotypes of the L. monocytogenes isolates by multiplex PCR assay. In the study, 51 L. monocytogenes colonies were isolated from 34 (29.3%) chicken meat samples (eleven [22.0%] carcasses and 23 [34.8%] pieces of meat) by IMS based cultivation technique and confirmed by PCR. According to the multiplex PCR results, all the 51 isolates were identified as genoserotype IIa (1/2a or 3a). L. monocytogenes isolates were also tested for their susceptibility to eight antibiotic (gentamicin, vancomycin, chloramphenicol, streptomycin, tetracycline, ampicillin, penicillin G, erythromycin) agents using the disk diffusion method. 14 isolates (27.45%) were susceptible to all eight antimicrobials drugs tested and the remaining 37 isolates (72.54%) were resistant to gentamicin (one isolate, 1.96%), vancomycin (four isolates, 7.84%), penicillin G (six isolates, 11.76%), streptomycin (nine isolates, 17.64%; resistant or intermediate), tetracycline (seven isolates, 13.72%) and ampicillin (six isolates, 11.76%). This study showed that antimicrobial resistance is not highly prevalent in L. monocytogenes isolated from chicken carcasses and pieces of meat. The presence of L. monocytogenes in chicken samples suggests an importance of this pathogen in chicken.

The presence of Campylobacter spp. and Salmonella was studied in 70 samples of fresh retail chicken pieces and in 40 samples of roast chicken. Total plate count was performed in every sample as well. Most of the samples of fresh chicken yielded total plate counts > 10(8)/piece (thigh), while in roast chicken these counts ranged from 10(3) to 10(5)/piece (leg and thigh). Campylobacter was isolated from 33% of fresh chicken and from no sample of roast chicken. Salmonella was isolated from 69% of fresh chicken and 2.5% of roast chicken. There was no relationship between total plate counts in fresh chicken and isolation of either Campylobacter or Salmonella. Sixty percent of the Salmonella isolates belonged to serotype S. anatum, and about 50% of the isolates of Campylobacter were identified as being C. coli. The only Salmonella-positive sample of roast chicken yielded three serotypes: S. give, S. muenster, and S. manhattan. Presence of Campylobacter and Salmonella in chicken is of concern, due to the risk of spreading from the raw food to other cooked foods. The isolation of pathogens from roast chicken indicates mishandling during processing and/or storage of the product.

Rönner, Anna-Clara; Lindmark, Hans

2007-06-01

Campylobacter jejuni infection is a significant cause of foodborne gastroenteritis worldwide. Consumption and handling of poultry products is believed to be the primary risk factor for campylobacteriosis. Risk assessments require quantitative data, and C. jejuni is enumerated usually by direct plating, which sometimes allows growth of non-Campylobacter bacteria. The objective of the present study was to develop a quantitative real-time PCR method (q-PCR) for enumerating C. jejuni in chicken rinse without a culturing step. The procedure to obtain the template for the PCR assay involved (i) filtration of 10 ml of chicken rinse, (ii) centrifugation of the sample, and (iii) total DNA extraction from the pellet obtained using a commercial DNA extraction kit. The detection limit of the method was comparable to that for plating 100 microl of chicken rinse on modified charcoal cefoperazone deoxycholate agar, and the detection limit could be further improved 10-fold by concentrating the DNA eluate by ethanol precipitation. A close correlation for spiked chicken rinse was obtained for the results of the quantitative real-time PCR method and direct plating (r = 0.99). The coefficient of correlation for the methods was 0.87 when samples from chicken carcasses on the slaughter line were analyzed, whereas a lower correlation (r = 0.76) was obtained when samples from retail carcasses were analyzed. Greater variation in the proportion of dead and/or viable but not culturable Campylobacter types in the retail samples may explain the decreased correlation between the methods. Overall, the new method is simple and fast and the results obtained are closely correlated with those for direct plating for samples containing a low proportion of dead Campylobacter cells.

The aim of this study was to investigate the maternal genealogical pattern of chicken breeds sampled in Europe. Sequence polymorphisms of 1256 chickens of the hypervariable region (D-loop) of mitochondrial DNA (mtDNA) were used. Median-joining networks were constructed to establish evolutionary relationships among mtDNA haplotypes of chickens, which included a wide range of breeds with different origin and history. Chicken breeds which have had their roots in Europe for more than 3000 years were categorized by their founding regions, encompassing Mediterranean type, East European type and Northwest European type. Breeds which were introduced to Europe from Asia since the mid-19th century were classified as Asian type, and breeds based on crossbreeding between Asian breeds and European breeds were classified as Intermediate type. The last group, Game birds, included fighting birds from Asia. The classification of mtDNA haplotypes was based on Liu et al.'s (2006) nomenclature. Haplogroup E was the predominant clade among the European chicken breeds. The results showed, on average, the highest number of haplotypes, highest haplotype diversity, and highest nucleotide diversity for Asian type breeds, followed by Intermediate type chickens. East European and Northwest European breeds had lower haplotype and nucleotide diversity compared to Mediterranean, Intermediate, Game and Asian type breeds. Results of our study support earlier findings that chicken breeds sampled in Europe have their roots in the Indian subcontinent and East Asia. This is consistent with historical and archaeological evidence of chicken migration routes to Europe. © 2015 Stichting International Foundation for Animal Genetics.

This study was performed to determine the prevalence and to semiquantify Campylobacter spp. on chicken meat samples at 4 selected local wet markets in Nueva Ecija, Philippines, and to determine the antimicrobial resistance patterns of the Campylobacter isolates. Out of 120 chicken meat samples, 57 (47.5%) were Campylobacter spp. positive. The majority of isolated Campylobacter strains were identified as Campylobacter coli (54.4%) and 45.6% as Campylobacter jejuni. Most of these positive samples (52.6%) showed a very high quantitative Campylobacter contamination (most probable number > 2,400/g, lower confidence limit 580/g). For antimicrobial resistance testing, 44 C. coli/jejuni isolates were tested using the agar disk diffusion method. Out of these, 77.3% were resistant to ampicillin, followed by ciprofloxacin (70.4%), tetracycline (54.6%), erythromycin (20.2%), and gentamicin (11.4%). Of the isolates, 36.4% (n = 16) were resistant to 1 antimicrobial agent, 34.1% (n = 15) were resistance to 3 antimicrobial agents, 13.6% (n = 6) to 2 antimicrobial agents, 9.1% (n = 4) to 4 antimicrobial agents, and 6.8% (n = 3) to all 5 antimicrobial agents tested. Our data demonstrate a high contamination of fresh chicken meat with Campylobacter spp. at retail in the Philippines. The detected high Campylobacter prevalences and quantitative loads on chicken meat at retail in the Philippines highlight the need to implement efficient intervention measures along the food chain and to encourage sanitary handling of poultry meat.

Toxicological and histopathological investigations of tissues of commercially slaughtered chickens were carried out to provide a preliminary evaluation of the incidence of occurrence of ochratoxin A (OTA) in chicken sold in Serbian retail market. In addition, the etiology of nephropathies of these chickens was elucidated. The majority of these tissue samples were not found to contain measurable amounts of OTA. Moreover, the OTA levels found in analyzed tissues were generally low and there was no positive correlation between the presence of OTA and the frequency of histopathological changes. Histopathological changes such as degenerative changes in the kidneys and liver differed from the classical description of the mycotoxic nephropathy, indicating that the chicken nephropathy observed in Serbia may have a multitoxic etiology with possible synergistic effect between microorganisms and natural toxins, usually present in low concentrations. The low OTA results also suggested that chicken meat available in the retail market in Serbia are unlikely to pose any significant adverse health risk to the consumers with respect to OTA toxicity.

Salmonella bacteria that survive cooking or that cross-contaminate other food during meal preparation and serving represent primary routes of consumer exposure to this pathogen from chicken. In the present study, enrichment real-time PCR (qPCR) was used to enumerate Salmonella bacteria that contaminate raw chicken parts at retail or that cross-contaminate cooked chicken during simulated meal preparation and serving. Whole raw chickens obtained at retail were partitioned into wings, breasts, thighs, and drumsticks using a sterilized knife and cutting board, which were then used to partition a cooked chicken breast to assess cross-contamination. After enrichment in buffered peptone water (400 ml, 8 h, 40°C, 80 rpm), subsamples were used for qPCR and cultural isolation of Salmonella. In some experiments, chicken parts were spiked with 0 to 3.6 log of Salmonella Typhimurium var. 5- to generate a standard curve for enumeration by qPCR. Of 10 raw chickens examined, 7 (70%) had one or more parts contaminated with Salmonella. Of 80 raw parts examined, 15 (19%) were contaminated with Salmonella. Of 20 cooked chicken parts examined, 2 (10%) were cross-contaminated with Salmonella. Predominant serotypes identified were Typhimurium (71%) and its variants (var. 5-, monophasic, and nonmotile) and Kentucky (18%). The number of Salmonella bacteria on contaminated parts ranged from one to two per part. Results of this study indicated that retail chicken parts examined were contaminated with low levels of Salmonella, which resulted in low levels of cross-contamination during simulated meal preparation and serving. Thus, if consumers properly handle and prepare the chicken, it should pose no or very low risk of consumer exposure to Salmonella.

We determined the prevalence and types of extended-spectrum β-lactamase (ESBL)-producing and carbapenem-resistant Escherichia coli in raw retail beef, chicken, pork, fruit and vegetables in five UK regions in 2013-14. Raw meat (n=397), and fruit and vegetable samples (n=400) were purchased from retail stores in London, East Anglia, North West England, Scotland and Wales. Samples were tested for the presence of ESBL-producing E. coli by plating enriched samples on CHROMagar CTX and CHROMagar ESBL, for AmpC-type E. coli by plating on "CHROMagar FOX" (CHROMagar ECC+16mg/L cefoxitin), and for carbapenem-resistant E. coli by plating on CHROMagar KPC. Additionally, pre-enrichment counts were performed on the above agars, and on CHROMagar ECC. Isolates of interest were characterised by MALDI-ToF to confirm identification, by PCR for bla CIT, bla CTX-M, bla OXA , bla SHV and bla TEM genes; ESBL or bla CIT genes were sequenced. Only 1.9% and 2.5% of beef and pork samples, respectively were positive for ESBL-producing E. coli after enrichment compared with 65.4% of chicken samples. 85.6% positive samples from chicken meat carried bla CTX-M-1 ; bla CTX-M-15 was not detected. None of the fruits or vegetables yielded ESBL-producing E. coli and none of the meat, fruit or vegetable samples yielded carbapenem-resistant E. coli. Retail chicken was more frequently a source of ESBL-producing E. coli than were beef, pork, fruit or vegetables. None of the foodstuffs yielded E. coli with CTX-M-15 ESBL, which dominates in human clinical isolates in the UK, and none yielded carbapenem-resistant E. coli. Crown Copyright © 2016.

In this study we examined the presence of Staphylococcus aureus and staphylococcal enterotoxin A (SEA) in 20 industrial breaded chicken products obtained from different retail butchers and supermarket stores in Italy. The levels of contamination in the products analyzed were quite low, although the pH values and water activities (a(w)) in the samples considered were in ranges favorable for S. aureus growth. As demonstrated by phenotypic and molecular characterization, in spite of the high percentage of coagulase-positive Staphylococcus strains, only three strains could be referred to the species S. aureus. Moreover, all the strains were negative in PCR assays targeting staphylococcal enterotoxin genes (seA to seE, seG to seJ, and seM to seO), as well as the toxic shock syndrome toxin 1 gene, and no SEA was detected in the retail breaded chicken samples analyzed by a reversed passive latex agglutination assay or by Western blotting. Hence, we evaluated the thermal resistance of two strains of SEA-producing S. aureus in a laboratory-scale preparation of precooked breaded chicken cutlets. The heat treatment employed in the manufacture determined the inactivation of S. aureus cells, but the preformed SEA remained active during product storage at 4 degrees C. The presence of the staphylococci and, in particular, of S. aureus in the retail breaded chicken products analyzed is a potential health risk for consumers since the pH and a(w) values of these kinds of products are favorable for S. aureus growth. The thermal process used during their manufacture can limit staphylococcal contamination but cannot eliminate preformed toxins.

This study was conducted to determine the prevalence of Listeria monocytogenes in retailed meats, comprising beef, chicken, and pork, in the Tokyo metropolitan area. A total of 379 samples of retailed meat were collected from 1998 to 2003, most of which were obtained by simultaneously purchasing the three classes of meat from a shop and then making another simultaneous purchase of meat from the same shop a few weeks later. The prevalence of L. monocytogenes was 28.0%, and the serotypes isolated were mainly 1/2a, 1/2b, 1/2c, and 4b. Comparison of the prevalence of each serotype among the classes of meat showed a predominant distribution of serotypes 1/2a, 1/2b, and 4b in chicken, while serotype 1/2c was dominant in pork. A total of nine cases considered to be due to persistence and/or cross-contamination were found. Most of the strains involved in persistence and/or cross-contamination were of serotypes 1/2c or 4b. These results suggest that contamination in retailed meat in Japan is at almost the same level as in other countries and that chicken has the highest potential as a source of contamination and infection. In addition, we suggest that the ecological niche of serotype 1/2c is distinct from those of 1/2a, 1/2b, and 4b, which may explain why human hosts have less opportunity to be exposed to serotype 1/2c and why there is a lower rate of isolation of this serotype from cases of human listeriosis.

In the United States, tens of thousands of inspections of tobacco retailers are conducted each year. Various sampling choices can reduce travel costs, emphasize enforcement in areas with greater non-compliance, and allow for comparability between states and over time. We sought to develop a model sampling strategy for state tobacco retailer inspections. Using a 2014 list of 10,161 North Carolina tobacco retailers, we compared results from simple random sampling; stratified, clustered at the ZIP code sampling; and, stratified, clustered at the census tract sampling. We conducted a simulation of repeated sampling and compared approaches for their comparative level of precision, coverage, and retailer dispersion. While maintaining an adequate design effect and statistical precision appropriate for a public health enforcement program, both stratified, clustered ZIP- and tract-based approaches were feasible. Both ZIP and tract strategies yielded improvements over simple random sampling, with relative improvements, respectively, of average distance between retailers (reduced 5.0% and 1.9%), percent Black residents in sampled neighborhoods (increased 17.2% and 32.6%), percent Hispanic residents in sampled neighborhoods (reduced 2.2% and increased 18.3%), percentage of sampled retailers located near schools (increased 61.3% and 37.5%), and poverty rate in sampled neighborhoods (increased 14.0% and 38.2%). States can make retailer inspections more efficient and targeted with stratified, clustered sampling. Use of statistically appropriate sampling strategies like these should be considered by states, researchers, and the Food and Drug Administration to improve program impact and allow for comparisons over time and across states. The authors present a model tobacco retailer sampling strategy for promoting compliance and reducing costs that could be used by U.S. states and the Food and Drug Administration (FDA). The design is feasible to implement in North Carolina. Use of

Inorganic arsenic (iAs) causes cancer and possibly other adverse health outcomes. Arsenic-based drugs are permitted in poultry production; however, the contribution of chicken consumption to iAs intake is unknown. We sought to characterize the arsenic species profile in chicken meat and estimate bladder and lung cancer risk associated with consuming chicken produced with arsenic-based drugs. Conventional, antibiotic-free, and organic chicken samples were collected from grocery stores in 10 U.S. metropolitan areas from December 2010 through June 2011. We tested 116 raw and 142 cooked chicken samples for total arsenic, and we determined arsenic species in 65 raw and 78 cooked samples that contained total arsenic at ≥ 10 µg/kg dry weight. The geometric mean (GM) of total arsenic in cooked chicken meat samples was 3.0 µg/kg (95% CI: 2.5, 3.6). Among the 78 cooked samples that were speciated, iAs concentrations were higher in conventional samples (GM = 1.8 µg/kg; 95% CI: 1.4, 2.3) than in antibiotic-free (GM = 0.7 µg/kg; 95% CI: 0.5, 1.0) or organic (GM = 0.6 µg/kg; 95% CI: 0.5, 0.8) samples. Roxarsone was detected in 20 of 40 conventional samples, 1 of 13 antibiotic-free samples, and none of the 25 organic samples. iAs concentrations in roxarsone-positive samples (GM = 2.3 µg/kg; 95% CI: 1.7, 3.1) were significantly higher than those in roxarsone-negative samples (GM = 0.8 µg/kg; 95% CI: 0.7, 1.0). Cooking increased iAs and decreased roxarsone concentrations. We estimated that consumers of conventional chicken would ingest an additional 0.11 µg/day iAs (in an 82-g serving) compared with consumers of organic chicken. Assuming lifetime exposure and a proposed cancer slope factor of 25.7 per milligram per kilogram of body weight per day, this increase in arsenic exposure could result in 3.7 additional lifetime bladder and lung cancer cases per 100,000 exposed persons. Conventional chicken meat had higher iAs concentrations than did conventional antibiotic

For food to be entirely safe from the microbiological viewpoint, it must need to contain the least possible counts of microorganisms of hygienic importance. This investigation aims to study the possible use of gamma radiation for bacterial decontamination of chicken products which are produced in Egypt. One hundred and twenty samples of frozen chicken kofta and burgers (60 each) were purchased from retail markets at Cairo Governorate. They were surveyed for the hygienic quality as well as the effect of gamma radiation (dose levels of 1, 2 and 3 kGy) on the bacterial population, chemical and sensory quality of these products. The results indicated that the total aerobic bacterial counts (APC) ranged from 106 to 107 cfu/g in the examined samples. Moreover, some samples were contaminated with food borne pathogens such as Listeria species and Salmonella species. Gamma irradiation greatly reduced the microbial density of the studied food samples. The microbial reduction increased as the dose level of irradiation increase, whereas irradiation of chicken products at 3 kGy dose reduced aerobic counts and eliminated Salmonella and Listeria species, also it proved to be of great importance in increasing the safety and acceptability of ready to eat frozen chicken products with no adverse effect on their chemical or sensory quality

In 2012 and 2014 the Norwegian monitoring programme for antimicrobial resistance in the veterinary and food production sectors (NORM-VET) showed that 124 of a total of 406 samples (31%) of Norwegian retail chicken meat were contaminated with extended-spectrum cephalosporin-resistant Escherichia coli. The aim of this study was to compare selected cephalosporin-resistant E. coli from humans and poultry to determine their genetic relatedness based on whole genome sequencing (WGS). Escherichia coli representing three prevalent cephalosporin-resistant multi-locus sequence types (STs) isolated from poultry (n=17) were selected from the NORM-VET strain collections. All strains carried an IncK plasmid with a bla CMY-2 gene. Clinical E. coli isolates (n=284) with AmpC-mediated resistance were collected at Norwegian microbiology laboratories from 2010 to 2014. PCR screening showed that 29 of the clinical isolates harboured both IncK and bla CMY-2 . All IncK/bla CMY-2 -positive isolates were analysed with WGS-based bioinformatics tools. Analysis of single nucleotide polymorphisms (SNP) in 2.5 Mbp of shared genome sequences showed close relationship, with fewer than 15 SNP differences between five clinical isolates from urinary tract infections (UTIs) and the ST38 isolates from poultry. Furthermore, all of the 29 clinical isolates harboured IncK/bla CMY-2 plasmid variants highly similar to the IncK/bla CMY-2 plasmid present in the poultry isolates. Our results provide support for the hypothesis that clonal transfer of cephalosporin-resistant E. coli from chicken meat to humans may occur, and may cause difficult-to-treat infections. Furthermore, these E. coli can be a source of AmpC-resistance plasmids for opportunistic pathogens in the human microbiota.

Gibbs, Rachael A; Rymer, Caroline; Givens, D I

2013-06-01

The primary objective was to determine fatty acid composition of skinless chicken breast and leg meat portions and chicken burgers and nuggets from the economy price range, standard price range (both conventional intensive rearing) and the organic range from four leading supermarkets. Few significant differences in the SFA, MUFA and PUFA composition of breast and leg meat portions were found among price ranges, and supermarket had no effect. No significant differences in fatty acid concentrations of economy and standard chicken burgers were found, whereas economy chicken nuggets had higher C16:1, C18:1 cis, C18:1 trans and C18:3 n-3 concentrations than had standard ones. Overall, processed chicken products had much higher fat contents and SFA than had whole meat. Long chain n-3 fatty acids had considerably lower concentrations in processed products than in whole meat. Overall there was no evidence that organic chicken breast or leg meat had a more favourable fatty acid composition than had meat from conventionally reared birds. Copyright © 2012 Elsevier Ltd.

Oscar, T P

2017-09-01

The flow pack wrapper is a popular packaging choice for retail sale of whole chickens. However, it may provide a favorable environment for growth and spread of Salmonella within the package, leading to an outbreak of salmonellosis. To investigate this possibility, a process risk model was developed that predicted the risk of salmonellosis from chicken parts prepared from whole chickens sold in flow pack wrappers and subjected to proper storage (6 h at 4°C) or improper storage (72 h at 15°C) before preparation. The model had four unit operations (pathogen events): (i) preparation (contamination), (ii) cooking (death), (iii) serving (cross-contamination), and (iv) consumption (dose-response). Data for prevalence, number, and serotype of Salmonella on chicken parts were obtained by whole sample enrichment, real-time PCR. Improper storage increased (P chicken parts from 10.6% (17 of 160) to 41.2% (66 of 160) and incidence of cross-contamination of cooked chicken from 10% (4 of 40) to 52.2% (24 of 46). Improper storage also increased (P chicken part and from 0.048 ± 0.089 to 3.08 ± 1.50 log per cooked chicken part. The predominant serotypes isolated (n = 111) were Typhimurium (34.2%), Typhimurium var 5- (20.7%), Kentucky (12.6%), Enteritidis (11.7%), and Heidelberg (8.1%). When chicken was properly stored before preparation, the model predicted that risk of salmonellosis was low and sporadic with only six cases per 100 simulations of 10 5 chicken parts. However, when 0.1 to 1% of chickens were improperly stored before preparation, the model predicted that salmonellosis would increase (P chicken parts. These results indicated that the flow pack wrapper provided a favorable environment for growth and spread of Salmonella within the package and that even when only a small percentage of packages were subjected to improper storage before preparation, the risk and size of an outbreak of salmonellosis from chicken parts increased significantly.

To detect the prevalence, the seasonal occurrence and distribution of Salmonella serotypes in poultry products and to determine the resistance profile of Salmonella isolates. A total of 96 skin-on chicken carcasses and 30 liver samples were analysed between May 2007 and May 2009 from twenty-two different commercial farm brands found in retail market countrywide. Salmonella was isolated from 38 (39·5%) of 96 chicken carcasses and from 10 (33·3%) of 30 liver samples. Higher isolation rate (60·4%) was observed in carcasses detected during summer (May to October), and lower isolation rate (18·7%) was observed in carcasses detected during winter (November to April); in liver samples, the positive rates were 53·4 and 13·2%, respectively. Twelve serotypes were detected with the serotypes Hadar, Enteritidis and Blockley being the most prevalent at 29·2, 22·9 and 12·5%, respectively. Nine of 11 Salm. Enteritidis isolates occurred during summer. Of 48 isolates, 38 (79%) were resistant to one or more of the antimicrobial agents used. The highest resistance rates were found to the following antimicrobials: streptomycin (64·5%), tetracycline (56·2%), nalidixic acid (39·5%), ampicillin and rifampicin (33·3%). The relatively high Salmonella spp. contamination rates of raw chicken meat and liver have been detected. Salm. Enteritidis isolates peaked in summer, increasing the risk to human health. Antibiotic resistance of Salmonella still remains a threat as resistance plasmids may be extensively shared between animal and humans. The study enabled us to improve the data on the seasonal occurrence of Salmonella and to determine the antimicrobial pattern profile and trends in Salmonella strains isolated from poultry retail products in Greece. © 2012 The Authors.

Staphylococcus aureus can be carried on the skin and nasal passages of humans and animals as a commensal. A case of human methicillin-resistant S. aureus infection resulting from contact with pork has been reported. Poultry carcasses are sold at retail with the skin intact, but pork and beef typically are not. Thus, the risk of methicillin-resistant S. aureus human infection from whole raw poultry carcasses may be greater than that of exposure from pork or beef. The objective of this study was to isolate and characterize S. aureus from whole retail poultry carcasses and compare the isolates to S. aureus isolates from humans. A total of 25 S. aureus isolates were collected from 222 whole poultry carcasses. The isolates were characterized phenotypically with antibiotic resistance disc diffusion assays and genotypically using multilocus sequence typing. A total of 17 S. aureus isolates obtained from healthy humans were included and characterized in the same way as the poultry isolates. Staphylococcus spp. were recovered from all poultry carcasses. Only 25 poultry carcasses (11.2%) were contaminated with S. aureus. Of these 25 isolates, 36% were resistant to at least one of the antibiotics tested and 20% were resistant to two or more antibiotics tested. However, 100% of the human isolates were resistant to at least one of the antibiotics and 94% were resistant to two or more antibiotics. The results of the multilocus sequence typing indicate that most of the isolates grouped according to source. These results indicate a low prevalence of S. aureus present in poultry, and the isolates were not phenotypically similar to human isolates. The low number of S. aureus isolates from this study indicates that chicken carcasses would appear to not be a significant source of this bacterium.

Irradiation is considered one of the most efficient technological processes for the reduction of microorganisms in food, It can be used to improve the safety of food products, and to extend their shelf lives. The aim of this study was to improve the hygienic quality of chicken through radiation processing. As part of the study a microbial assessment of broiler chicken thighs from three retail outlets (supermarket, local markets and farms) was conducted. The total viable count and total coliform counts were determined. Hygienic quality indicator organisms such as Escherichia coli, Salmonella and Staphylococcus aureus were isolated and microbial counts made. Radiation sensitivity test to determine the D 10 (decimal reduction does) of E. coli on chicken at refrigeration and frozen temperature were conducted. D 10 values were 0.22 ± 0.02 and 0.32 ± 0.03 kGy at refrigerated and frozen temperatures respectively. A storage test consisting of an uninoculated pack experiment and a challenge test to explore the effect of irradiation and frozen food storage on the total viable count and survival of E. coli was conducted. Chicken thigh samples were treated with 0 (non irradiated), 2.0, 4.0, 6.0 and 8.0 kGy of gamma irradiation and held frozen for 56 days. The control and irradiated samples were stored at -18 o C and underwent microbial analysis and sensory evaluation at 7 days intervals. It was observed that irradiation and frozen storage reduced microbial loads. There were significant differences in sensory quality characteristics during freezing storage in chicken meat. The combination of irradiation and frozen storage resulted in greater overall reductions on microbial loads thus improving hygienic quality. (au)

Full Text Available This present study examines the preservation quality of dressed chicken procured from different sources of processing during storage at –18±1ºC. Breast portion of the dressed birds obtained from three different sources, viz. market/road side slaughtered chicken (MSC, retail slaughtered chicken (RSC, and scientifically slaughtered chicken (SSC, were cut into chunks, divided into 250 g portions, packed in polyethylene bags, stored at –18±1ºC and evaluated at 30 days intervals for changes in quality attributes. Frozen storage had no marked influence on pH change of the samples. SSC samples had higher extract release volume (15.34±0.08 to 13.45±0.93 ml than MSC (13.00±0.19 to 9.91±0.97 ml and RSC samples (13.65±0.24 to 11.70±1.21ml. There was significant increase (P<0.05 in thiobarbituric acid of all three sample types during storage but values were well below the threshold level of spoilage. SSC samples showed lower tyrosine content throughout frozen storage compared to MSC and RSC samples. A significant decline in microbial load, viz. total viable count, coliform count, psychrophilic count and yeast and moulds count were noticed during frozen storage. Organoleptic attributes, viz. appearance, flavour, texture and overall palatability were not affected due to frozen storage except juiciness in MSC samples which decreased (P<0.05 from 6.53±0.13 to 5.96±0.11 on 90 days of storage. Although the scientifically slaughtered chicken had better quality, all the sample types could be stored at –18±1ºC till 90 days without much deterioration in their quality.

Directory of Open Access Journals (Sweden)

HULYA CAKMAK

Full Text Available ABSTRACT Chicken meat in two different forms (chicken meat and chicken meat powder were added into white flour and whole wheat blend baguette bread formulations for protein enrichment and finally developing new and healthy snacks. The chicken meat and powder levels were 10% for white flour baguette, and 15% for whole wheat blend. The dried baguette samples were packaged under 100% N2, and physical, chemical, microbiological and sensorial properties were evaluated during 3 months of storage. Protein content of chicken meat powder added samples were found statistically higher than chicken meat added samples. Hardness of the snacks was significantly affected from type of chicken meat, such as values were higher for chicken meat added samples than chicken meat powder added samples. Lipid oxidation of the snacks was determined by TBA analysis, and TBA value for whole wheat mixture snack with 15% of chicken meat was the highest among all during storage. The highest overall acceptance score was obtained from white flour snack with 10% chicken meat. There was no coliform bacteria detected during storage and the results of yeast-mold count and aerobic plate count of snacks remained between the quantitative ranges.

The emergence and wide distribution of the transferable gene for linezolid resistance, cfr, in staphylococci of human and animal origins is of great concern as it poses a serious threat to the public health. In the present study, we investigated the emergence and presence of the multiresistance gene, cfr, in retail meat sourced from supermarkets and free markets of Guangzhou, China. A total of 118 pork and chicken samples, collected from Guangzhou markets, were screened by PCR for cfr. Twenty-two Staphylococcus isolates obtained from 12 pork and 10 chicken samples harbored cfr. The 22 cfr-positive staphylococci isolates, including Staphylococcus equorum (n = 8), Staphylococcus simulans (n = 7), Staphylococcus cohnii (n = 4), and Staphylococcus sciuri (n = 3), exhibited 17 major SmaI pulsed-field gel electrophoresis (PFGE) patterns. In 14 isolates, cfr was located on the plasmids. Sequence analysis revealed that the genetic structures (including ΔtnpA of Tn558, IS21-558, ΔtnpB, and tnpC of Tn558, orf138, fexA) of cfr in plasmid pHNTLD18 of a S. sciuri strain and in the plasmid pHNLKJC2 (including rep, Δpre/mob, cfr, pre/mob and partial ermC) of a S. equorum strain were identical or similar to the corresponding regions of some plasmids in staphylococcal species of animal and human origins. To the best of our knowledge, this is the first study to report the presence of the multiresistance gene, cfr, in animal meat. A high occurrence of cfr was observed in the tested retail meat samples.

Meat products may be vehicles of bacterial pathogens to humans, and Salmonella spp., Campylobacter spp., and Shiga toxin-producing Escherichia coli (STEC) are the most relevant. The aim of this study was to generate data on prevalence of these three pathogens in 552 samples of meat products (hot dogs, pork sausages, raw ground beef, and raw chicken legs) sold at retail in the city of Sao Paulo, Brazil. Salmonella spp. was detected in 5.8% (32/552) of samples, comprising pork sausages 62.5% (20/32) and chicken legs 37.5% (12/32). The counts of Salmonella spp. were low, ranging from Salmonella Typhimurium (28.1%), Salmonella I 4,[5],12:i:- (15.6%), Salmonella Enteritidis (12.5%), Salmonella Derby, and Salmonella Brandenburg (9.4%). Campylobacter spp. was detected in 33 samples (6.0%), comprising chicken legs (82%) and ground beef (18%). All samples were negative for STEC. These results suggest that meat products when subjected to inadequate cooking and/or cross-contamination with other products ready for consumption can lead to occurrence of outbreaks, highlighting the risks associated with them.

Antibiotic-resistant bacteria in poultry meat are a threat to public health. In this study, we compared the Enterococcus spp. loads and antibiotic-resistance profiles between carcasses of conventionally and organically raised chickens. A total of 144 chicken carcasses (72 conventional and 72 organic) was collected from local retail markets in Seoul, South Korea. Overall, 77.7% (112 of 144; 75% conventional and 80% organic) of chicken carcasses were positive for Enterococcus. The mean loads of Enterococcus spp. were greater in conventional chicken carcasses, at 2.9 ± 0.4 log CFU/mL, than those in organic chicken carcasses, at 1.78 ± 0.3 log CFU/mL (p organic chicken carcasses) was randomly selected for further analysis. The predominant species was Enterococcus faecalis in both conventional and organic chicken carcasses (57.7 and 76.9%, respectively; P > 0.05). Rates of resistance to ciprofloxacin and erythromycin, which are used in veterinary medicine in South Korea, were significantly higher in conventional chicken carcasses than in organic chicken carcasses. However, we found no difference between the rates of resistance to antibiotics such as vancomycin and tigecycline, which were not registered for use in veterinary medicine in South Korea, of Enterococcus isolates from conventional and organic chicken carcasses. In addition, although multidrug resistant isolates were obtained from both types of chicken samples, the prevalence of samples positive for Enterococcus was significantly higher in conventional chicken carcasses than in organic chicken carcasses (P organic chicken carcasses. A high level of gentamicin resistance was observed in isolates from not only conventional (5.8%) but also organic chicken (1.9%) carcasses, with no significant difference in rates between them (P > 0.05). Despite this, our results suggest that organic food certification is effective in reducing fecal contamination and the burden of antibiotic-resistant Enterococcus spp. in

This study aimed to investigate the effects of various mixtures of the chicken skin and wheat fiber on the properties of chicken nuggets. Two skin and fiber mixtures (SFM) were prepared using the following formulations; SFM-1: chicken skin (50%), wheat fiber (20%), and ice (30%); and SFM-2: chicken skin (30%), wheat fiber (20%), and ice (50%). Chicken nugget samples were prepared by adding the following amounts of either SFM-1 or SFM-2: 0%, 2.5%, 5%, 7.5%, and 10%. The water content for samples formulated with SFM-1 or SFM-2 was higher than in the control (pchicken nuggets was higher than that of cooked chicken nuggets for all the samples tested. Chicken nuggets formulated with SFM-1 and SFM-2 displayed higher cooking yields than the control sample. The hardness of the control sample was also lower than the samples containing SFM-1 and SFM-2. The sensory evaluation showed no significant differences between the control and the samples containing SFM. Therefore, the incorporation of a chicken skin and wheat fiber mixture improved the quality of chicken nuggets. PMID:26761796

Reduction of the microbial cell count in a frozen packaged chicken by ionizing radiation is an advantageous method with a microbiologically optimum dose of 4 kGy (5). However, the detection of irradiation in poultry is a problem in food analysis. Our study focused on to the possible changes in the fatty acid composition and formation of long-chain hydrocarbons in the chicken fat. The composition of chicken fat is complex. Therefore, our study was started with some pure fatty acids and a vegetable oil consisting mainly of triglycerides of fatty acids and having, qualitatively, the same fatty acids as the chicken. Pure olive oil (a retail oil from Italy) was chosen for the purpose. Later, also fat extracted from chicken skin was analysed. All samples were analysed as irradiated and non-irradiated. The results show that no new radiolytically induced fatty acids or other related compounds could be detected by using a BP-21 polar capillary column and flame ionization detector. Moreover, the composition of the major fatty acids remained constant. In the qualitative analysis of hydrocarbons produced by irradiation, it was shown that there is a distinct difference in the hydrocarbon pattern between non-irradiated and irradiated chicken skin tissues.

This study compared fat and fatty acids in cooked retail chicken meat from conventional and organic systems. Fat contents were 1.7, 5.2, 7.1 and 12.9 g/100 g cooked weight in skinless breast, breast with skin, skinless leg and leg with skin respectively, with organic meat containing less fat overall (Porganic meat contained less than did conventional meat (1850 vs. 2538 mg/100 g; POrganic meat was also lower (Pvs. 180 mg/100 g) and, whilst it contained more (Pvs. 13.7 mg/100 g), this was due to the large effect of one supermarket. This system by supermarket interaction suggests that poultry meat labelled as organic is not a guarantee of higher long chain n-3 fatty acids. Overall there were few major differences in fatty acid contents/profiles between organic and conventional meat that were consistent across all supermarkets. Copyright © 2015 Elsevier Ltd.

Extended-spectrum β-lactamase (ESBL)-producing Salmonella are one of the most important public health problems in developed countries. ESBL-producing Salmonella strains have been isolated from humans in Asian countries neighboring Japan, along with strains harboring the plasmid-mediated extended-spectrum cephalosporin (ESC)-resistance gene, ampC (pAmpC). However, only a few studies have investigated the prevalence of ESC-resistant Salmonella in chicken products in Japan, which are the main vehicle of Salmonella transmission. The aim of this study was to investigate the prevalence of ESBL-producing, pAmpC-harboring, or carbapenem-resistant Salmonella in chicken products in Japan. In total, 355 out of 779 (45.6%) chicken product samples collected from 1996-2010 contained Salmonella, resulting in 378 distinct isolates. Of these isolates, 373 were tested for resistance to ESCs, cephamycins, or carbapenems. Isolates that showed resistance to one or more of these antimicrobials were then examined by PCR and DNA sequence analysis for the presence of the bla(CMY), bla(CTX-M), bla(TEM), and bla(SHV) resistance genes. Thirty-five resistant isolates were detected, including 26 isolates that contained pAmpC (bla(CMY-2)), and nine ESBL-producing isolates harboring bla(CTX-M) (n = 4, consisting of two bla(CTX-M-2) and two bla(CTX-M-15 genes)), bla(TEM) (n = 4, consisting of one bla(TEM-20) and three bla(TEM-52) genes), and bla(SHV) (n = 1, bla(SHV-12)). All pAmpC-harboring and ESBL-producing Salmonella isolates were obtained from samples collected after 2005, and the percentage of resistant isolates increased significantly from 0% in 2004 to 27.9% in 2010 (P for trend = 0.006). This increase was caused in part by an increase in the number of Salmonella enterica subsp. enterica serovar Infantis strains harboring an approximately 280-kb plasmid containing bla(CMY-2) in proximity to ISEcp1.

This study was performed to evaluate consumers’ perception and acceptance of selected pork and chicken sausage (budim and chicken sausages, respectively) from Zlatiborac Meat Company. Sensory evaluation was performed by Serbian consumers (n=1157) in three retail stores in Belgrade. Consumers were asked for their preference for taste, salt content and smoke of two sausages and to recognize the kind of meat which was used to make these meat products. Consumers evaluated taste, salt content and smoke flavor of budim and chicken sausages with the highest percentage of the best offered answer. Between 47-55%, 72-76% and 82-84% of consumers evaluated the taste of sausages as good, the salt content as well-balanced and the smoke flavor as balanced, respectively. Tukey’s HSD test was applied to analyze variations of male and female perception and acceptance of analyzed sausages.

Escherichia coli producing CTX-M-15 enzyme began to rapidly spread in the UK from around 2003 but other types also occur, notably CTX-M-14. We examined breasts from UK-reared (n = 62) and imported (n = 27) chickens as potential sources of quinolone-resistant E. coli with bla(CTX-M) genes. A further 40 samples for which the country of rearing could not be identified were examined. During 2006, 129 fresh and frozen chicken breast fillets were purchased from retail outlets in the West Midlands. These were cultured for E. coli on CLED agar containing 8 mg/L ciprofloxacin and carrying a 10 microg cefpodoxime disc. Resistant isolates were identified and typed by RAPD fingerprinting; bla(CTX-M) was identified by PCR and genotyped by reverse-line hybridization. The country of rearing was identified from the packaging for 89 of 129 purchased samples. Only one of the 62 UK-reared chicken samples carried E. coli producing a CTX-M-1 enzyme, whereas 10 of 27 samples reared overseas had E. coli with CTX-M enzymes. Specifically, 4/10 Brazilian, 3/4 Brazilian/Polish/French, and 2/2 Dutch samples had E. coli with CTX-M-2 enzymes. Six of 40 samples for which the country of rearing was not known had producers of CTX-M enzymes, 5 of them with CTX-M-14. Quinolone-resistant E. coli with various CTX-M beta-lactamase genes that are common in human infections worldwide were found in imported chicken breasts, indicating a possible source for gut colonization. Samples from Brazil were commonly positive for E. coli with CTX-M-2, the dominant bla(CTX-M) genotype from human infections in South America, which is currently rare in clinical infections in the UK. CTX-M-15, the dominant CTX-M type in human infections in the UK, was not found in chicken isolates, suggesting that the UK-reared chickens are not a reservoir of CTX-M-15.

This study was carried out to establish the residual nitrate and nitrite and concentrations of six heavy metals in meat products samples that purchased from retail outlets in Sharkia governorate, Egypt. The possibility of using gamma irradiation at doses of 3, 5 and 7 KGy for reducing residual nitrate and nitrite was studied. The results showed that most of samples under investigation above the maximum permissible limit of nitrate in Egypt. Gamma irradiation at doses of 3, 5 and 7 KGy reduced the levels of nitrate and nitrite proportionally to applied doses. The irradiation dose of 7 KGy was more effective for reducing the level of residual nitrate and nitrite. Heavy metals concentrations were determined using the inductively coupled plasma spectrometry (ICPS) in non-irradiated samples. The results showed that the concentration of Pb in meat products was ranged between 0.643-0.828, 0.548, 0.598-0.844, 0.574-0.877, 0.324-0.568 and 0.156-0.432 mg/kg (wet weight basis) in pastirma, chicken luncheon, fresh sausages, burger, minced chicken and minced beef meat, respectively, but the values of Hg ranged between 0.0965-0.839, 0.121, 0.147-0.218, 0.114-0.258, 0.087-0.143 and 0.057-0.124 mg/kg in pastirma, chicken luncheon, fresh sausages, burger, minced chicken and beef meat, respectively. The content of iron ranged between 0.336, 0.362-4.284, 0.364-0.611, 0.264-0.336 and 0.276-0.314 mg/kg in chicken luncheon, fresh sausages, burger, minced chicken and beef meat, respectively. However, the results indicated that, the most of meat products under investigation had high concentrations from toxic metals of Pb and Hg than the permissible limits that recommended by FAO/WHO of person daily. Therefore, the consumption of high amount of these commodities dose not pose a health risk for the consumer

Full Text Available Cryptosporidium is one of the most important parasites in poultry, and this pathogen can infect more than 30 avian species. The present study investigated the infection rate of Cryptosporidium among broiler chicken flocks. A total of 385 fecal samples from broiler chickens in 7 regions of Zhejiang Province collected from November 2010 to January 2012 were examined by microscopy. Thirty-eight (10% samples were positive for Cryptosporidium infection, and 3 genotypes (Cryptosporidium baileyi, Cryptosporidium meleagridis, and avian genotype II were identified by PCR and sequencing. A phylogenetic tree of the isolates was analyzed. These results suggest that cryptosporidiosis is widespread in poultry in Zhejiang Province, and is a potential threat to public health as well as the economy. This is the first report about the infection rate and molecular characterization of Cryptosporidium in broiler chickens in Zhejiang.

The antimicrobial effect of roasted coffee filtrate (CF) and dicarbonyls on Salmonella Typhimurium and Salmonella Enteritidis in raw ground chicken breast meat (GCB) was investigated. Coffee was brewed and filtered before addition to GCB. Coffee filtrate with and without added caffeine, methylglyoxal, and/or glyoxal was added to GCB and then inoculated with Salmonella Typhimurium and Salmonella Enteritidis. Ground chicken samples were stomached with peptone water at days 1, 3, 5, and 7, plated on XLD agar with a TSA overlay, and Salmonella survivors were enumerated. CF alone gave less than a 1 Log reduction in all runs compared to control GCB with no treatment. Methylglyoxal (2.28 mg/g GCB) had the greatest antimicrobial effect against Salmonella Typhimurium and Salmonella Enteritidis in GCB with average Log reductions of 2.27 to 3.23, respectively, over the 7 d duration of the experiment compared to control GCB with no treatment. A 1 Log reduction was observed in GCB with CF, 0.93 mg glyoxal, and 1 mg caffeine/g chicken compared to the control and GCB with only CF. Heat-produced coffee compounds could potentially reduce Salmonella in retail ground chicken and chicken products. © 2011 Institute of Food Technologists®

2008-09-01

Full Text Available Abstract Background A real-time multiplex PCR assay was developed for the detection of multiple Salmonella serotypes in chicken samples. Poultry-associated serotypes detected in the assay include Enteritidis, Gallinarum, Typhimurium, Kentucky and Dublin. The traditional cultural method according to EN ISO 6579:2002 for the detection of Salmonella in food was performed in parallel. The real-time PCR based method comprised a pre-enrichment step in Buffered Peptone Water (BPW overnight, followed by a shortened selective enrichment in Rappaport Vasilliadis Soya Broth (RVS for 6 hours and subsequent DNA extraction. Results The real-time multiplex PCR assay and traditional cultural method showed 100% inclusivity and 100% exclusivity on all strains tested. The real-time multiplex PCR assay was as sensitive as the traditional cultural method in detecting Salmonella in artificially contaminated chicken samples and correctly identified the serotype. Artificially contaminated chicken samples resulted in a detection limit of between 1 and 10 CFU per 25 g sample for both methods. A total of sixty-three naturally contaminated chicken samples were investigated by both methods and relative accuracy, relative sensitivity and relative specificity of the real-time PCR method were determined to be 89, 94 and 87%, respectively. Thirty cultures blind tested were correctly identified by the real-time multiplex PCR method. Conclusion Real-time PCR methodology can contribute to meet the need for rapid identification and detection methods in food testing laboratories.

Exposure to retail tobacco marketing is associated with youth smoking, but most studies have relied on self-reported measures of exposure, which are prone to recall bias. To examine whether exposure to retail cigarette advertising, promotions, and retailer compliance is associated with youth smoking-related outcomes using observational estimates of exposure. Data on retail cigarette advertising and promotions were collected from a representative sample of licensed tobacco retailers in New York annually since 2004. County-level estimates of retail cigarette advertising and promotions and retailer compliance with youth access laws were calculated and linked to the New York Youth Tobacco Survey, administered to 54,671 middle and high school students in 2004, 2006, and 2008. Regression models examined whether cigarette advertising, promotions, and retailer compliance were associated with youth's awareness of retail cigarette advertising, attitudes about smoking, susceptibility to smoking, cigarette purchasing behaviors, and smoking behaviors. Living in counties with more retail cigarette advertisements is associated with youth having positive attitudes about smoking (odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.03-1.19, P advertising and promotions may help reduce youth smoking.

This study was conducted to find out the fraud in chicken-processed meat ingredients to protect consumers from commercial adulteration and authentication through a reliable way: direct amplification of conserved segment of cytochrome b gene of mitochondrial DNA, in addition, using species-specific primer assay for a certain cytochrome b. The results reported that chicken-processed meats were identified as a chicken meat based on amplification of conserved cytochrome b gene of mtDNA, while different fragments sizes were produced after the application of species-specific primer as follows: 227, 157, 274, 331, 389 and 439 bp for raw meat of chicken, goat, cattle, sheep, pig and horse, respectively. The results revealed that all chicken meat products are produced with 227 bp in size. While, an adulteration with pork stuffs was observed in some of the chicken meat products using a species-specific primer of cytochrome b gene, namely, chicken luncheon and chicken burger. This study represents a reliable technique that could be used to provide a promising solution for identifying the commercial adulteration and substitutions in processed meat in retail markets.

Employer commitment is a key factor in an effective safety program, yet limited research has focused on the safety priorities of retail store managers. To address this, the U.S. National Institute for Occupational Safety and Health recruited 4 experienced ergonomists, who met and interviewed 9 retailers in different parts of the eastern USA. The reports from the 9 interviews were used to document the hazards facing retailers and the interventions they attempted. Those interviewed were managers/owners of establishments that ranged from a small bakery with 11 employees to a supermarket with 85 or more employees. The main hazards across all establishments included overexertion, contact-with-objects, and falls-to-the-same-level. We also compared the retailers' perceptions of safety hazards with injuries from actual hazards as supplied by the U.S. Bureau of Labor Statistics. This report provides insight into the retailers' perceptions of safety hazards as well as their commitment to the prevention of workplace injuries.

Outbreak of food-poisoning caused by Salmonella virchow in spit-roasted chicken.

Semple, A B; Turner, G C; Lowry, D M

1968-12-28

Salmonella virchow food-poisoning acquired from eating chicken caused illness in at least 50 people who attended a tennis club function in Liverpool, and in many other people in the Merseyside area. In some cases the illness was severe, with positive blood cultures, and 35 people were admitted to hospital.The source of infection was a retail shop which received deep-frozen chickens already contaminated with S. virchow from a packing-station in Cheshire. These chickens were spit-roasted after inadequate thawing and subsequently handled under unhygienic conditions. The result was a massive build-up of salmonella contamination in the shop and in the chicken portions sold.S. virchow was isolated from over 160 patients and contacts in the Merseyside area during the outbreak and many continued to excrete the organism in the faeces after four months. Antibiotic treatment was not recomended because there was no evidence that it shortened the duration of excretion.A high rate of contamination of chickens from a packing-station by a salmonella type capable of causing serious disease in man is clearly a public health problem which cannot be ignored.The use of rotary spits for roasting chickens requires thorough investigation and appraisal, because as operated at present they evidently constitute a public health hazard.

Dias, Karina T S; Braga Junior, Sergio S

2016-01-01

Retail growth is a result of the diversification of departments with the intention to look to consumer's needs and level of demand. Pressed by consumers and by the law, the adoption of environmental preservation practices is becoming stronger among grocery retailers. The objective of this research was to analyse the practices of reverse logistics performed by a retailer and measure the amount of waste generated by each department. To reach the proposed goal, a field research study was conducted to directly observe a grocery retailer in the state of Sao Paulo, Brazil, for a period of 6 months and monitor the amounts of cardboard and plastic discarded by each department. Using the Wuppertal method, the first result observed was that the retailer stopped its monthly production of approximately 20 tonne of biotic and abiotic material, which influence global warming and degradation of the ozone layer. Another result observed with the implementation of reverse logistics, was that the general grocery department mostly used cardboard and plastic. This sector includes products such as food cupboard, drinks, household, health and beauty, and pet articles. The fresh fruit and vegetable department and the meat, chicken and frozen department were increasingly using less plastic and cardboard packaging, increasing the use of returnable and durable packaging and thus promoting sustainability. © The Author(s) 2015.

The present study was conducted to estimate the effectiveness of sanitary procedures on food contact surfaces and food handlers’ hands in Serbian retail establishments. For that purpose, a total of 970 samples from food contact surfaces and 525 samples from workers’ hands were microbiologically analyzed. Results of total aerobic plate count and total Enterobacteriaceae count showed that the implemented washing and disinfection procedures, as a part of HACCP plans, were not effective enough in most retail facilities. Constant and intensive education of employees on proper implementation of sanitation procedures are needed in order to ensure food safety in the retail market.

Estimates of the zoonotic diseases are helpful for monitoring and improving public health. Laboratory-based surveillance provides crucial information for assessing zoonotic disease trends and developments. Toxoplasmosis is considered as a zoonotic disease and has both medical and veterinary importance since it leads to abortion in humans and several animal species. In view of the worldwide importance of T. gondii, this study aimed to estimate the prevalence of T. gondii in chickens from the Delta of Egypt. A total of 304 blood and brain samples were collected from Egyptian chickens from Gharbiya, Qalyoubiya, Minufiya, Beheira, Kafr EL-Shaykh and Dakahlia Provinces. In order to determine the serological and histopathological prevalence of T. gondii, the samples were examined by ELISA, histopathology and immunohistochemistry (IHC). The prevalence of T. gondii was 11.18, 6.91, 6.91 % by ELISA, histopathology and IHC, respectively. Statistically significant differences in the prevalence of T. gondii were observed on the basis of season, sex and habitat. These data provide valuable information regarding the epidemiology of T. gondii infections in Egyptian chickens, which can be employed in developing efficient strategies for disease management and control.

This study identified the sensory characteristics and consumer preference for chicken meat in Guinea. Five chicken samples [live village chicken, live broiler, live spent laying hen, ready-to-cook broiler, and ready-to-cook broiler (imported)] bought from different locations were assessed by 10 trained panelists using 19 sensory attributes. The ANOVA results showed that 3 chicken appearance attributes (brown, yellow, and white), 5 chicken odor attributes (oily, intense, medicine smell, roasted, and mouth persistent), 3 chicken flavor attributes (sweet, bitter, and astringent), and 8 chicken texture attributes (firm, tender, juicy, chew, smooth, springy, hard, and fibrous) were significantly discriminating between the chicken samples (Pchicken, the live spent laying hen, and the ready-to-cook broiler (imported) were very well represented and clearly distinguished from the live broiler and the ready-to-cook broiler. One hundred twenty consumers expressed their preferences for the chicken samples using a 5-point Likert scale. The hierarchical cluster analysis of the preference data identified 4 homogenous consumer clusters. The hierarchical cluster analysis results showed that the live village chicken was the most preferred chicken sample, whereas the ready-to-cook broiler was the least preferred one. The partial least squares regression (PLSR) type 1 showed that 72% of the sensory data for the first 2 principal components explained 83% of the chicken preference. The PLSR1 identified that the sensory characteristics juicy, oily, sweet, hard, mouth persistent, and yellow were the most relevant sensory drivers of the Guinean chicken preference. The PLSR2 (with multiple responses) identified the relationship between the chicken samples, their sensory attributes, and the consumer clusters. Our results showed that there was not a chicken category that was exclusively preferred from the other chicken samples and therefore highlight the existence of place for development of

Full Text Available Abstract Background Two-dimensional gel electrophoresis (2-DE is a powerful method to study protein expression and function in living organisms and diseases. This technique, however, has not been applied to avian bursa of Fabricius (BF, a central immune organ. Here, optimized 2-DE sample preparation methodologies were constructed for the chicken BF tissue. Using the optimized protocol, we performed further 2-DE analysis on a soluble protein extract from the BF of chickens infected with virulent avibirnavirus. To demonstrate the quality of the extracted proteins, several differentially expressed protein spots selected were cut from 2-DE gels and identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS. Results An extraction buffer containing 7 M urea, 2 M thiourea, 2% (w/v 3-[(3-cholamidopropyl-dimethylammonio]-1-propanesulfonate (CHAPS, 50 mM dithiothreitol (DTT, 0.2% Bio-Lyte 3/10, 1 mM phenylmethylsulfonyl fluoride (PMSF, 20 U/ml Deoxyribonuclease I (DNase I, and 0.25 mg/ml Ribonuclease A (RNase A, combined with sonication and vortex, yielded the best 2-DE data. Relative to non-frozen immobilized pH gradient (IPG strips, frozen IPG strips did not result in significant changes in the 2-DE patterns after isoelectric focusing (IEF. When the optimized protocol was used to analyze the spleen and thymus, as well as avibirnavirus-infected bursa, high quality 2-DE protein expression profiles were obtained. 2-DE maps of BF of chickens infected with virulent avibirnavirus were visibly different and many differentially expressed proteins were found. Conclusion These results showed that method C, in concert extraction buffer IV, was the most favorable for preparing samples for IEF and subsequent protein separation and yielded the best quality 2-DE patterns. The optimized protocol is a useful sample preparation method for comparative proteomics analysis of chicken BF tissues.

Full Text Available The Objective of this study was to identify the existence of Campylobacter jejuni based on phenotypic and genotypic characteristic in local chicken and chicken meats. Samples of local chicken intestine and meat were tested for the bacterial existence. Phenotypic examination was carried out by means of cultivation followed by gram staining and biochemical tests. Genotypic examination was conducted by polymerase chain reaction (PCR using genus specific16S rRNA gene at 816 bp and membrane-associated protein A (mapA gene at 589 bp as Campylobacter jejuni species-specific gene. The result of phenotypic detection revealed the existence of Campylobacter spp as gram negative, curved rod shape, oxidase positive, urease negative and motile. Genotypic examination also indicated the existence of bacteria using both primers. However, no Campylobacter jejuni detected from meat of the chickens. The results suggest that the method of PCR using a primer detecting species-specific gene of Campylobacter jejuni gives a rapid and accurate detection of the bacteria as compared to that using phenotypic and biochemical test. Identification of Campylobacter spp from chicken meats should be improved with enrichment method and sample collection.

Oluwayelu, D O; Todd, D; Olaleye, O D

2008-12-01

This work reports the first molecular analysis study of chicken anaemia virus (CAV) in backyard chickens in Africa using molecular cloning and sequence analysis to characterize CAV strains obtained from commercial chickens and Nigerian backyard chickens. Partial VP1 gene sequences were determined for three CAVs from commercial chickens and for six CAV variants present in samples from a backyard chicken. Multiple alignment analysis revealed that the 6% and 4% nucleotide diversity obtained respectively for the commercial and backyard chicken strains translated to only 2% amino acid diversity for each breed. Overall, the amino acid composition of Nigerian CAVs was found to be highly conserved. Since the partial VP1 gene sequence of two backyard chicken cloned CAV strains (NGR/CI-8 and NGR/CI-9) were almost identical and evolutionarily closely related to the commercial chicken strains NGR-1, and NGR-4 and NGR-5, respectively, we concluded that CAV infections had crossed the farm boundary.

Characterizing genetic diversity of contemporary pacific chickens using mitochondrial DNA analyses.

Directory of Open Access Journals (Sweden)

Kelsey Needham Dancause

Full Text Available BACKGROUND: Mitochondrial DNA (mtDNA hypervariable region (HVR sequences of prehistoric Polynesian chicken samples reflect dispersal of two haplogroups--D and E--by the settlers of the Pacific. The distribution of these chicken haplogroups has been used as an indicator of human movement. Recent analyses suggested similarities between prehistoric Pacific and South American chicken samples, perhaps reflecting prehistoric Polynesian introduction of the chicken into South America. These analyses have been heavily debated. The current distribution of the D and E lineages among contemporary chicken populations in the Western Pacific is unclear, but might ultimately help to inform debates about the movements of humans that carried them. OBJECTIVES: We sought to characterize contemporary mtDNA diversity among chickens in two of the earliest settled archipelagos of Remote Oceania, the Marianas and Vanuatu. METHODS: We generated HVR sequences for 43 chickens from four islands in Vanuatu, and for 5 chickens from Guam in the Marianas. RESULTS: Forty samples from Vanuatu and three from Guam were assigned to haplogroup D, supporting this as a Pacific chicken haplogroup that persists in the Western Pacific. Two haplogroup E lineages were observed in Guam and two in Vanuatu. Of the E lineages in Vanuatu, one was identical to prehistoric Vanuatu and Polynesian samples and the other differed by one polymorphism. Contrary to our expectations, we observed few globally distributed domesticate lineages not associated with Pacific chicken dispersal. This might suggest less European introgression of chickens into Vanuatu than expected. If so, the E lineages might represent lineages maintained from ancient Pacific chicken introductions. The Vanuatu sample might thus provide an opportunity to distinguish between maintained ancestral Pacific chicken lineages and replacement by global domesticates through genomic analyses, which could resolve questions of contemporary

2000-01-01

The presence of Campylobacter spp. was investigated in 100 samples of roasted chicken tacos sold in well-established commercial outlets and semisettled street stands in Mexico City. From 600 colonies displaying Campylobacter morphology only 123 isolates were positive. From these isolates, 51 (41%) were identified as C. jejuni, 23 (19%) as C. coli, and 49 (40%) as other species of this genus. All of the 27 positive samples came from one location where handling practices allowed cross-contamination of the cooked product. The results indicate that these ready-to-consume products are contaminated with these bacteria, representing a potential risk for consumers, especially in establishments lacking adequate sanitary measures to prevent cross-contamination.

Identification of Multiple Subtypes of Campylobacter jejuni in Chicken Meat and the Impact on Source Attribution

Directory of Open Access Journals (Sweden)

John A. Hudson

2013-09-01

Full Text Available Most source attribution studies for Campylobacter use subtyping data based on single isolates from foods and environmental sources in an attempt to draw epidemiological inferences. It has been suggested that subtyping only one Campylobacter isolate per chicken carcass incurs a risk of failing to recognise the presence of clinically relevant, but numerically infrequent, subtypes. To investigate this, between 21 and 25 Campylobacter jejuni isolates from each of ten retail chicken carcasses were subtyped by pulsed-field gel electrophoresis (PFGE using the two restriction enzymes SmaI and KpnI. Among the 227 isolates, thirteen subtypes were identified, the most frequently occurring subtype being isolated from three carcasses. Six carcasses carried a single subtype, three carcasses carried two subtypes each and one carcass carried three subtypes. Some subtypes carried by an individual carcass were shown to be potentially clonally related. Comparison of C. jejuni subtypes from chickens with isolate subtypes from human clinical cases (n = 1248 revealed seven of the thirteen chicken subtypes were indistinguishable from human cases. None of the numerically minor chicken subtypes were identified in the human data. Therefore, typing only one Campylobacter isolate from individual chicken carcasses may be adequate to inform Campylobacter source attribution.

Full Text Available Food allergies and intolerances have increased during the last decades and regulatory authorities have taken different measures to prevent and manage consumers’ adverse reactions, including correct labelling of foods. Aim of this work was to search for soybean and lactose in meat products and meat preparations taken from retail in some provinces of Campania Region (Southern Italy and to evaluate the food labels compliance with Regulation (EU n.1169/2011. Soybean and lactose were searched using commercial kits in n. 58 samples of meat products produced in or distributed by 19 establishments, and in n. 55 samples of meat products and n. 8 of meat preparations produced in 21 plants. All samples were selected on the basis of the absence of any information on the labels about the presence of the two searched allergens, with the exception of n. 5 samples tested for lactose. Traces of soybean were detected in 50 out of the 58 examined samples, at concentrations up to 0.93 mg kg–1. Only two samples contained levels above the detection limit of 0.31 mg kg–1. Lactose levels ranging from 0.11 to 2.95 g/100 g, i.e. above the detection limit, were found in all the tested samples (n. 63. The results of the present research underline the need for careful controls and planning by operators as part of the self-control plans, and deserve attention from the competent authorities considering not only the consumers’ health but also the great attention media pay to regulations providing consumers with information on food.

2017-03-01

Full Text Available Objective: The main objective of this paper is to analyse the development of retail formats and their impact on the development of food retailing, through empirical testing of the largest food retailers within the timeframe 2009-2014. Research Design & Methods: This paper shall, in addition to the review of literature on the development of retail formats, focus on the analysis of the Global Power of Retailing report 2011-2016. Statistical material consists of the available data on the ranking of the largest retail companies, viewed by sales volume, in the period from 2009 to 2014, published annually by the consulting firm, Deloitte Touche. Findings: The research results show the dominant share of food retailers in the total number of retailers in the list of Top 250 retailers. In addition, the results point to a different structure of food retail formats in the period from 2009 to 2014. The position of individual food retailers in the list of the most successful ones changes over time and standard multiple regression results show that this is due to the introduction of new retail formats. Implications & Recommendations: Continuing innovation in the field of retail formats is very important to food retailers. Decision makers need to pay special attention and focus on increasing the sales volume and better ranking of companies in the list of most successful ones, where one of the factors is the introduction of new retail formats. Contribution & Value Added: The originality of this work lies in studying some aspects of the FDI inflow into the group of both similar and different countries in terms of economy.

There is a gap in knowledge of microbiological quality in raw chicken products produced by nonconventional methods and no studies have reported the microbiological quality of turkeys produced under different rearing environments. Thus, the aim of this study was to compare the microbiological quality of conventionally and organically reared whole chicken and turkey carcasses purchased from 3 retail outlets in Knoxville, Tenn., U.S.A. A total of 100 raw broiler chickens organically (n = 50) and 50 raw turkey carcasses consisting of 3 brands reared either conventionally (n = 25) or organically (n = 25) were evaluated. The FDA BAM protocol for rinsing poultry carcasses was used to enumerate of aerobic bacteria, Campylobacter, and Staphylococcus spp., and for qualitative analysis of Salmonella. Organic chickens from one brand had the highest average counts of aerobic bacteria, Staphylococcus spp. and Campylobacter (4.8, 4.8, and 4.7 Log10 CFU/mL rinsate, respectively) while the other organic brand had the lowest average counts (3.4, 3.3, and 3.1, respectively) of all 4 brands evaluated. The organic turkeys had the highest average counts of these same bacteria (4, 3.9, and 3.8, respectively) compared to the 2 brands of conventional turkeys evaluated. Salmonella (5% prevalence) was isolated only from organic chickens and turkeys. From these data, it appears that the microbiological quality of the raw product was not dependent on rearing conditions and, thus, it cannot be assumed that organic raw poultry is safer than conventionally raised poultry in terms of microbiological quality. © 2013 Institute of Food Technologists®

Full Text Available OBJECTIVE: To describe the prevalence and antimicrobial resistance of Salmonella spp. in frozen chicken carcasses at retail from 15 Brazilian cities. METHODS: A descriptive study of data from the Brazilian National Program for Monitoring the Prevalence of Bacterial Resistance in Chicken (PREBAF was conducted from September 2004 to July 2006. The program collected chicken carcasses in 15 state capitals of Brazil in the five geographic regions of the country. Standardized methodologies were used to isolate Salmonella­spp. and identify serotypes. The minimal inhibitory concentration method was used to test resistance to 18 antimicrobials. RESULTS: In 2 679 carcasses examined, the prevalence of Salmonella spp. was 2.7% (range 0.0%-8.9%. São Paulo State produced 50.6% of positive samples. Eighteen serotypes were identified. The most frequently occurring were Salmonella Enteritidis (48.8%, Salmonella Infantis (7.6%, Salmonella Typhimurium (7.2%, and Salmonella Heidelberg (6.4%. All 250 strains tested were resistant to one or more antibiotics, and 133 (53.2% were multidrug resistant (≥ 3 classes. S. Heidelberg was resistant to ceftriaxone (75.0% and to ceftiofur(43.8%. CONCLUSIONS: The prevalence of Salmonella spp. found in this study was relatively low. However, there were a high proportion of multidrug-resistant strains, including third-generation cephalosporins used to treat invasive salmonellosis. The results confirm the relevanceof the PREBAF program. It is recommended that PREBAF be improved, including a timely data analysis. A review of permitted limits for Salmonella spp. in retail chicken in Brazil is also needed.OBJETIVO: Describir la prevalencia y la resistencia a los antibióticos de Salmonella spp. en canales de pollo congeladas de venta al por menor en 15 ciudades del Brasil.

Juliane Alves

2013-12-01

Full Text Available Campylobacter spp. is a common cause of bacterial food-borne illness. Birds, especially poultry are primary reservoirs of C. jejuni. The aim of this study was to evaluate the occurrence of Campylobacter spp. in chicken cuts purchased in supermarkets of Londrina, Parana. A total of 50 samples of chicken cuts, such as breasts, thighs and drumsticks were analyzed. The confirmation of the presence of Campylobacter spp. was performed by identifying the suspected colonies on the selective medium using the polymerase chain reaction. Of the 50 samples analyzed, 28 (56% were positive for Campylobacter spp. Chicken meat, as observed in this study, is a possible source of Campylobacter transmission to humans. This study alerts for the importance to analyze the occurrence of Campylobacter in chicken meat, due to the significant number of positive samples observed and no available epidemiological data in Brazil. The correct orientation about handling and cooking of chicken meat is also necessary to prevent human infection by Campylobacter spp.

2008-03-01

The Asian H5N1 highly pathogenic avian influenza (HPAI) virus causes a systemic disease with high mortality of poultry and is potentially zoonotic. In both chickens and ducks, the virus has been demonstrated to replicate in both cardiac and skeletal muscle cells. Experimentally, H5N1 HPAI virus has been transmitted to chickens through the consumption of raw infected meat. In this study, we investigated virus replication in cardiac and skeletal muscle and in the trachea of chickens after experimental intranasal inoculation with the H5N1 HPAI virus. The virus was detected in tissues by real-time reverse transcription-polymerase chain reaction (RRT-PCR) and virus isolation, and in the trachea by RRT-PCR and a commercial avian influenza (AI) viral antigen detection test. A modified RNA extraction protocol was developed for rapid detection of the virus in tissues by RRT-PCR. The H5N1 HPAI virus was sporadically detected in meat and the tracheas of infected birds without any clinical sign of disease as early as 6 hr postinfection (PI), and was detected in all samples tested at 24 hr PI and later. No differences in sensitivity were seen between virus isolation and RRT-PCR in meat samples. The AI viral antigen detection test on tracheal swabs was a useful method for identifying infected chickens when they were sick or dead, but was less sensitive in detecting infected birds when they were preclinical. This study provides data indicating that preslaughter tracheal swab testing can identify birds infected with HPAI among the daily mortality and prevent infected flocks from being sent to processing plants. In addition, the modified RNA extraction and RRT-PCR test on meat samples provide a rapid and sensitive method of identifying HPAI virus in illegal contraband or domestic meat samples.

Day-old, straight-run broiler chickens were procured from a hatchery located in the Pacific Northwest. The chickens were subdivided individually into nine groups of 20 chickens. The chickens were tagged, housed in isolation chambers on wire, fed commercial broiler feed, and given water ad libitum. Three isolates of Campylobacter jejuni of poultry origin and one of human origin were tested in this study. Various C. jejuni cultures were inoculated into 9-day-old chickens by crop gavage. Four groups of 20 chickens were inoculated at a dose level of 0.5 ml of 1 x 10(2) colony-forming units (CFU)/ml. The other four groups were inoculated with 0.5 ml of 1 X 10(4) CFU/ml. One group of 20 chickens was kept as an uninoculated control group. Four randomly selected chickens from each of the inoculated and uninoculated groups were necropsied at 5, 12, and 19 days postinoculation (DPI). The C. jejuni was cultured and enumerated from a composite of the upper and midintestine and the cecum. Body weights of all chicken groups at 7 days of age and at 5, 12, and 19 DPI were measured and statistically analyzed. No significant differences were present in the mean body weights (MBWs) of 7-day-old, 5 DPI, and 12 DPI male and female broiler chickens inoculated with C. jejuni at both dose levels compared with uninoculated controls. Differences in MBWs of the male and female broilers at 19 DPI were observed in some of the groups. Results of the C. jejuni culture enumeration mean (CEM) of composite intestine samples at 5 DPI from all inoculated chicken groups, irrespective of the dose level, ranged from (2.5 +/- 5.0) x 10(2) to (2.8 +/- 4.8) x 10(5) CFU/g (mean +/- SD). Results of cecum C. jejuni CEM at 5 DPI inoculated at both dose levels ranged from (2.5 +/- 5.0) x 10(6) to (1 +/- 0.0) x 10(7) CFU/g in all treatment groups irrespective of the dose level. CEM results from the composite intestine samples at 12 and 19 DPI increased by 1 log unit, or sometimes more. Results of cecum C. jejuni

Irradiation of locally produced and imported food products was approved in the Kingdom of Saudi Arabia (KSA) in 2002. SureBeam Middle East (SME) has constructed the first food irradiation facility in Riyadh, KSA and will begin production irradiation in Q4 of 2005. In an effort to find efficient and cost effective means of irradiating frozen whole body chickens, SME has sponsored dose mapping studies using a 10 MeV dual electron beam processing system at the Electron Beam Food Research Facility at Texas A and M University (TAMU). Frozen chickens available to consumers in KSA range in size from nominal 600 grams to 1400 grams. Poultry processors typically provide retailers with equal weight birds packaged ten to a box (2 rows of 5 birds). Areal densities of the packages increase with the weight of the birds. For this study equivalent size birds were grown and processed by the Department of Poultry Science at TAMU and packaged in the same manner as in KSA. The goal of this investigation was to determine which size birds could be processed at a minimum dose of 2.5 kGy and not have the maximum dose exceed the level where negative sensory effects become noticeable. The minimum dose was chosen to reduce the population of any salmonella contamination by more than a factor of 1000. A description of the experimental set up and results of the dose mapping of frozen whole body chickens are reported herein, as are the results which indicate that electron beam processing of frozen chickens up to approximately 1000 grams can be readily accomplished and that processing of chickens up to 1400 grams may be possible Salmonella

To assess retailer compliance with a licensing scheme requiring tobacco retailers to list their business details with the government, to examine whether listed retailers are more likely to comply with a point-of-sale (POS) display ban and other in-store retailing laws and to explore variations in compliance between different retailer types and locations. An audit of 1739 retailers in New South Wales, Australia, was used to assess compliance with tobacco retailing legislation. Auditors actively searched for and audited unlisted retailers and all listed retailers in 122 metropolitan and regional postcodes. Multivariate generalised linear regression models were used to examine associations between compliance and retailer type, remoteness and demographic characteristics (socioeconomic level, proportion of population under 18 years and proportion born in Australia). One unlisted tobacco retailer was identified for every 12.6 listed tobacco retailers. Unlisted retailers were significantly more likely than listed retailers to breach in-store retailing laws (plaws was only 73.4%. Retailers in socioeconomically disadvantaged areas had lower compliance than those in high socioeconomic areas. Some tobacco retailers did not list their business details with the government as required, even though there was no financial cost to do so. Unlisted retailers were more likely to violate in-store regulations. The results suggest licensing schemes can be useful for providing a list of retailers, thus facilitating enforcement, but require a system to search for, and respond to, unlisted/unlicensed retailers.

Energy consumption and conservation in food retailing

International Nuclear Information System (INIS)

Tassou, S.A.; Ge, Y.; Hadawey, A.; Marriott, D.

2011-01-01

The total annual CO 2 emissions associated with the energy consumption of the major retail food outlets in the UK amount to around 4.0 MtCO 2 . The energy consumption and emissions from supermarkets varies widely and can depend on many factors such as the type and size of the store, business and merchandising practices and refrigeration and environmental control systems used. This paper provides energy consumption data of a sample of 2570 retail food stores from a number of major retail food chains in the UK. The sample covers all major store categories from convenience stores to hypermarkets and includes approximately 30% of the total number of stores in the UK having a net sales area more than 280 m 2 . The data show a wide variability of energy intensity even within stores of the same retail chain. A power law can be used to describe the variation of the average electrical energy intensity of the stores in the sample with sales area. If the electrical intensity of the stores above the average is reduced to the average by energy conservation measures, annual energy savings of the order of 10% or 840 GWh can be achieved representing 355,000 tonnes annual reduction in CO 2 emissions. The paper also discusses the major energy consuming processes in retail food stores and identifies opportunities for energy savings. - Research highlights: → Energy consumption by supermarkets in the UK is significant and a wide variability exists between stores of similar size. → Energy conservation measures to reduce energy consumption of individual stores to the average can produce a0% energy savings. → Significant opportunities for energy savings exist from the integration of HVAC and refrigeration equipment.

Nutrient Composition of Retail Samples of Australian Beef Sausages

Directory of Open Access Journals (Sweden)

Judy Cunningham

2015-11-01

Full Text Available Some nutrient data for beef sausages in Australia’s food composition table, NUTTAB 2010, is over 25 years old and may no longer reflect the composition of this popular food. To update this, 41 retail samples of fresh beef sausages were purchased in Melbourne, Australia, in May 2015. Each purchase was analysed, uncooked, for moisture, protein and fat. Sausages were then grouped by fat content into one of three composites and analysed for a wide range of nutrients, before and after dry heat cooking, the most popular sausage cooking method. Fat content in raw sausages averaged 14.9 g/100 g, 30% lower than NUTTAB values, varying from 7.3 to 22.6 g/100 g. This indicates it is possible to formulate leaner sausages that meet consumer expectations and may qualify for certain nutrition labelling statements. Under current Australian labelling requirements, two low fat sausages contain sufficient protein, B12, niacin, phosphorus and zinc to qualify as a good source of these nutrients and sufficient iron, selenium and vitamin A to qualify as a source of these. Sodium levels are higher than fresh beef, ranging from 680 to 840 mg/100 g. These data will be used to update NUTTAB and support product labelling and consumer education.

Optimal Retail Price Model for Partial Consignment to Multiple Retailers

Directory of Open Access Journals (Sweden)

Po-Yu Chen

2017-01-01

Full Text Available This paper investigates the product pricing decision-making problem under a consignment stock policy in a two-level supply chain composed of one supplier and multiple retailers. The effects of the supplier’s wholesale prices and its partial inventory cost absorption of the retail prices of retailers with different market shares are investigated. In the partial product consignment model this paper proposes, the seller and the retailers each absorb part of the inventory costs. This model also provides general solutions for the complete product consignment and the traditional policy that adopts no product consignment. In other words, both the complete consignment and nonconsignment models are extensions of the proposed model (i.e., special cases. Research results indicated that the optimal retail price must be between 1/2 (50% and 2/3 (66.67% times the upper limit of the gross profit. This study also explored the results and influence of parameter variations on optimal retail price in the model.

2016-04-01

Full Text Available Rapid developments in retailing sector bring about some ethical problems. Retailing is a faceto-face marketing activity by its nature. Thus, ethical problems in retailing directly affect consumers and consumer reactions turn directly to retailers. Therefore, defining and solving the ethical problems in retailing is an important issue for retailers. The main purpose of this study is to identify the food and clothing retailers’ perspective about ethical purchase decision making process and their evaluations on this subject. Beside this, identifying the differences of these evaluations in terms of the demographic characteristics of retailers is another objective of this study. Findings show that retailers generally approve ethical behaviors and disapprove unethical behaviors. In addition, evaluations of retailers differ in terms of some demographic characteristics. Results of the study also show that retailers are sensitive about unethical actions and behaviors and they believe that all the retailers must act according to ethical principles.

Full Text Available Brand awareness, together with other behavioural indicators (sympathy, trust, image, satisfaction or loyalty, is one of the main vectors that has an essential contribution to the outline of brand equity in general and to that of retail brand, in particular. The perception upon these indicators must be taken into consideration by production, service or retail companies in order to be able to identify their position on target markets, and in order to be able to create an adequate strategy that would help them reach the desired positioning. The aim of this paper is, on one hand, to reveal both the dimensions of brand awareness, and the relationship between these and consumers brand perception and, on the other hand, to offer a suitable instrument to measure awareness level of various retail chains. Questioning of almost 4.000 consumers indicates a significant awareness of the retailers that have been on the selected market for a longer period of time.

As recreational marijuana expands, it is critical to develop standardized surveillance measures to study the retail environment. To this end, our research team developed and piloted a tool assessing recreational marijuana retailers in a convenience sample of 20 Denver retailers in 2016. The tool assesses: (i) compliance and security (e.g. age-of-sale signage, ID checks, security cameras); (ii) marketing (i.e. promotions, product availability and price) and (iii) contextual and neighborhood features (i.e. retailer type, facilities nearby). Most shops (90.0%) indicated the minimum age requirement, all verified age. All shops posted interior ads (M = 2.6/retailer, SD = 3.4), primarily to promote edibles and other non-smoked products. Price promotions were common in shops (73.7%), 57.9% used social media promotions and 31.6% had take-away materials (e.g. menus, party promotions). Nearly half of the shops (42.1%) advertised health claims. All shops offered bud, joints, honey oil, tinctures, kief, beverages, edibles and topicals; fewer sold clones and seeds. Six shops (31.6%) sold shop-branded apparel and/or paraphernalia. Prices for bud varied within and between stores ($20-$45/'eighth', ∼3.5 g). Twelve were recreational only, and eight were both recreational and medicinal. Liquor stores were commonly proximal. Reliability assessments with larger, representative samples are needed to create a standardized marijuana retail surveillance tool. © The Author 2017. Published by Oxford University Press.

2015-02-01

Production of germline chimaeric chickens by the transfer of cultured primordial germ cells (PGC) is a useful system for germline manipulation. A novel culture system was developed for chicken PGC isolated from embryonic blood. The isolated PGC were cultured on feeder cells derived from chicken embryonic fibroblast. The cultured PGC formed colonies and they proliferated about 300-times during the first 30 days. The cultured PGC retained the ability to migrate to recipient gonads and were also chicken VASA homologue (CVH)-positive. Female PGC were present in the mixed-sex PGC populations cultured for more than 90 days and gave rise to viable offspring efficiently via germline chimaeric chickens. Male cultured PGC were transferred to recipient embryos and produced putative chimaeric chickens. The DNA derived from the cultured PGC was detected in the sperm samples of male putative chimaeric chickens, but no donor derived offspring were obtained. Donor-derived offspring were also obtained from germline chimaeric chickens by the transfer of frozen-thawed cultured PGC. The culture method for PGC developed in the present study is useful for manipulation of the germline in chickens, such as preservation of genetic resources and gene transfer.

Avian metapneumovirus (aMPV) causes upper respiratory tract infections in chickens and turkeys. Although the swollen head syndrome (SHS) associated with aMPV in chickens has been reported in Korea since 1992, this is the study isolating aMPV from chickens in this country. We examined 780 oropharyngeal swab or nasal turbinate samples collected from 130 chicken flocks to investigate the prevalence of aMPV and to isolate aMPV from chickens from 2004-2008. Twelve aMPV subtype A and 13 subtype B strains were detected from clinical samples by the aMPV subtype A and B multiplex real-time reverse transcription polymerase chain reaction (RRT-PCR). Partial sequence analysis of the G glycoprotein gene confirmed that the detected aMPVs belonged to subtypes A and B. Two aMPVs subtype A out of the 25 detected aMPVs were isolated by Vero cell passage. In animal experiments with an aMPV isolate, viral RNA was detected in nasal discharge, although no clinical signs of SHS were observed in chickens. In contrast to chickens, turkeys showed severe nasal discharge and a relatively higher titer of viral excretion than chickens. Here, we reveal the co-circulation of aMPV subtypes A and B, and isolate aMPVs from chicken flocks in Korea.

Zhang, Zhichao; Richardson, Christine E; Hennebelle, Marie; Taha, Ameer Y

2017-10-01

Fatty acid extraction methods are time-consuming and expensive because they involve multiple steps and copious amounts of extraction solvents. In an effort to streamline the fatty acid extraction process, this study compared the standard Folch lipid extraction method to a one-step method involving a column that selectively elutes the lipid phase. The methods were tested on raw beef, salmon, and chicken. Compared to the standard Folch method, the one-step extraction process generally yielded statistically insignificant differences in chicken and salmon fatty acid concentrations, percent composition and weight percent. Initial testing showed that beef stearic, oleic and total fatty acid concentrations were significantly lower by 9-11% with the one-step method as compared to the Folch method, but retesting on a different batch of samples showed a significant 4-8% increase in several omega-3 and omega-6 fatty acid concentrations with the one-step method relative to the Folch. Overall, the findings reflect the utility of a one-step extraction method for routine and rapid monitoring of fatty acids in chicken and salmon. Inconsistencies in beef concentrations, although minor (within 11%), may be due to matrix effects. A one-step fatty acid extraction method has broad applications for rapidly and routinely monitoring fatty acids in the food supply and formulating controlled dietary interventions. © 2017 Institute of Food Technologists®.

Full Text Available Broiler meat can become contaminated with Campylobacter of intestinal origin during processing. The present study aimed to identify the prevalence of Campylobacter in broiler flocks and meat contamination at retail shops, and determine the influence of semi-automated and wet market processing on Campylobacter contamination of neck skin samples. Samples were collected from semi-automated plants (n = 102 and wet markets (n = 25. From each batch of broilers, pooled caecal samples and neck skin samples were tested for Campylobacter. Broiler meat purchased from retail outlets (n = 37 was also tested. The prevalence of Campylobacter colonized broiler flocks was 67%. The contamination of meat at retail was 59%. Both semi-automated and wet market processing resulted to contaminate the broiler neck skins to the levels of 27.4% and 48%, respectively. When Campylobacter-free broiler flocks were processed in semi-automated facilities 15% (5/33 of neck skin samples became contaminated by the end of processing whereas 25% (2/8 became contaminated after wet market processing. Characterization of isolates revealed a higher proportion of C. coli compared to C. jejuni. Higher proportions of isolates were resistant to important antimicrobials. This study shows the importance of Campylobacter in poultry industry in Sri Lanka and the need for controlling antimicrobial resistance.

2014-12-01

Full Text Available Multidrug resistant bacteria (MDR bacteria, such as extended spectrum beta-lactamase (ESBL Enterobacteriaceae, methicillin resistant Staphylococcus aureus (MRSA, and vancomycin-resistant Enterococci (VRE, pose a challenge to the human health care system. In recent years, these MDR bacteria have been detected increasingly outside the hospital environment. Also the contamination of food with MDR bacteria, particularly of meat and meat products, is a concern. The aim of the study was to evaluate the occurrence of MDR bacteria in chicken meat on the Austrian market. For this study, 50 chicken meat samples were analysed. All samples originated from chickens slaughtered in Austrian slaughterhouses and were marked as produced in Austria. Samples were analysed for the presence of ESBL Enterobacteriaceae, methicillin resistant Staphylococci and VRE. Resistance genes of the isolated bacteria were characterised by PCR and sequencing. In the present study 26 ESBL producing E. coli, five mecA gene harbouring Staphylococci (but no MRSA, and four VRE were detected in chicken meat samples of Austrian origin. In 24 (48% of the samples no ESBL Enterobacteriaceae, MRSA, methicillin resistant coagulase negative Staphylococcus (MRCNS or VRE could be detected. None of the samples contained all three types of investigated multiresistant bacteria. In concordance to previous studies, CTX-M-1 and SHV-12 were the dominant ESBL genes.

2002-08-01

Chicken cooked under well-controlled conditions and commercial chicken products were screened for heterocyclic amines (HAs). Chicken samples were boiled, deep-fried, pan-fried, oven-roasted, cooked in an unglazed clay pot or in a roasting bag in the oven, and oven broiled. 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (4,8-DiMeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 1-methyl-9H-pyrido[3,4-b]indole (harman) and 9H-pyrido[3,4-b]indole (norharman) were identified in several samples. Chicken cooked at low temperatures contained low amounts of HAs. In pan-fried chicken breasts, MeIQx was detected in amounts below 2 ng/g, 4,8-DiMeIQx below 0.6 ng/g, and PhIP in amounts up to 38 ng/g. Harman and norharman were detected in almost all samples (below 15 ng/g). In skin from a commercially barbecued chicken, MeIQx, 4,8-DiMeIQx and PhIP were detected, while only traces of MeIQx were detected in the meat. MeIQx was detected in a commercial chicken flavour, 0.1 ng/ml. No HAs were detected in pan-fried chicken liver. The results show that the content of HAs in chicken cooked in various ways is low if prepared at low temperatures, and increases with increasing cooking temperature. PhIP formation seems to start accelerating at cooking temperatures around or above 200 degrees C. Colour development increases with cooking temperature, but no correlation with HA content was observed.

Full Text Available Toxoplasma gondii is an important foodborne zoonosis. Free-range chickens are at particularly high risk of infection and are also excellent indicators of soil contamination by oocysts. In the present study, hearts of 77 freerange chickens were collected at slaughter. T. gondii meat juice enzyme-linked immunosorbent assay was performed with a commercial kit, following validation with positive controls, from experimentally infected chickens, and negative ones. Out of 77 samples, only 66 gave sufficient meat juice for serology. Of these, 24 (36.4% were positive for T. gondii considering the 5*standard deviation values (calculated on the optical density of negative controls, while all the samples were negative considering sample/positive% values. Parasite-specific polymerase chain reaction was carried out on all samples obtained from heart tissue and none were positive for the presence of T. gondii DNA. Results would suggest that further study on the use of meat juice with a validated serological test to detect T. gondii in chickens could lead to widespread epidemiological studies in this important intermediate host. However, sample collection and test specificity require further evaluation.

We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

Multivariate approach to assess in vitro Fe bioaccessibility in chicken meat

Directory of Open Access Journals (Sweden)

Náira da Silva CAMPOS

Full Text Available Abstract A 32 factorial design was employed to develop an in vitro digestion method for estimation of Fe bioaccessible fractions in cooked chicken meat. The effects of sample size and the in vitro bioaccessible fractions of this essential element were evaluated. A sample preparation method employing a microwave assisted digestion with dilute nitric acid was used prior to total Fe determination. For the bioacessibility studies, the optimized procedure employed 7.5 g of sample and 6% w/v of an acid pepsin solution. This procedure was applied to two kinds of chicken meat samples: breast and liver. Flame Atomic Absorption Spectrometry was used to determine total and bioaccessible (chyme or soluble portion levels of iron in the samples. With respect to total Fe content, the bioaccessible fractions of Fe found in these samples were around 23% and 56 %, for breast and chicken liver, respectively.

Full Text Available This paper provides an evaluation of the strategy alignment of the South African retail sector with the National Development Plan (NDP governance values and objectives. The paper considers the commercial realities which form the framework for retail decision-makers when they address the challenges in aligning their business growth strategies with the regulatory framework of a capable, developmental state. Within that context, the outcomes of a retail stakeholder alignment study of the NDP strategy themes are analysed. The method involved a policy survey of a purposive sample of retail business and governance stakeholders. The survey findings reflect retailer alignment with many NDP regulatory and ‘active citizenry’ strategies, but with strong beliefs that others are not the retail business sector’s governance responsibility.

Salmonella is one of the most common causes of foodborne illnesses in humans in the United States, and domestic poultry is considered an important source of this pathogen. Salmonella enterica subsp. enterica serovar Heidelberg is the fourth most commonly reported Salmonella from retail meats and food animals in the United States. We assessed the genotypes and antimicrobial resistance phenotypes of Salmonella Heidelberg isolated from various chicken and turkey hatcheries and breeder farms in the Midwest. The genotypes of 33 S. Heidelberg isolates from chickens ( n = 19) and turkeys ( n = 14) were compared using pulsed-field gel electrophoresis analysis. Cluster analysis of the fingerprints showed that the majority of the chicken isolates grouped together with 87% similarity; those from turkeys clustered with 88% similarity. Similarity between chicken and turkey isolates was also high (86%). Isolates from turkeys were generally more genetically diverse than those from chickens. Antimicrobial susceptibility analysis detected resistance to sulfisoxazole (36% of the isolates), streptomycin (33%), gentamicin (27%), tetracycline (24%), ampicillin and amoxicillin-clavulanic acid (15%), cefoxitin (12%), ceftriaxone and ceftiofur (12%), and chloramphenicol (9%). None of the isolates was resistant to azithromycin, ciprofloxacin, or nalidixic acid. Although the number of the isolates was limited in our study, we conclude that S. Heidelberg isolates from the same host generally clustered together and that a considerable number of the isolates were resistant to a number of antimicrobial agents.

Antimicrobial resistance is increasing among clinical Campylobacter cases and is common among isolates from other sources, specifically retail poultry - a major source of human infection. In this study the antimicrobial susceptibility of isolates from a UK-wide survey of Campylobacter in retail poultry in 2001 and 2004-5 was investigated. The occurrence of phenotypes resistant to tetracycline, quinolones (ciprofloxacin and naladixic acid), erythromycin, chloramphenicol and aminoglycosides was quantified. This was compared with a phylogeny for these isolates based upon Multi Locus Sequence Typing (MLST) to investigate the pattern of antimicrobial resistance acquisition. Antimicrobial resistance was present in all lineage clusters, but statistical testing showed a non-random distribution. Erythromycin resistance was associated with Campylobacter coli. For all antimicrobials tested, resistant isolates were distributed among relatively distant lineages indicative of widespread acquisition. There was also evidence of clustering of resistance phenotypes within lineages; indicative of local expansion of resistant strains. These results are consistent with the widespread acquisition of antimicrobial resistance among chicken associated Campylobacter isolates, either through mutation or horizontal gene transfer, and the expansion of these lineages as a proportion of the population. As Campylobacter are not known to multiply outside of the host and long-term carriage in humans is extremely infrequent in industrialized countries, the most likely location for the proliferation of resistant lineages is in farmed chickens.

Methicillin-resistant Staphylococcus aureus (MRSA) has been detected in retail meats, although large-scale studies are scarce. We conducted a one-year survey in 2010-2011 within the framework of the National Antimicrobial Resistance Monitoring System. Among 3520 retail meats collected from eight U.S. states, 982 (27.9%) contained S. aureus and 66 (1.9%) were positive for MRSA. Approximately 10.4% (107/1032) of S. aureus isolates, including 37.2% (29/78) of MRSA, were multidrug-resistant (MDRSA). Turkey had the highest MRSA prevalence (3.5%), followed by pork (1.9%), beef (1.7%), and chicken (0.3%). Whole-genome sequencing was performed for all 66 non-redundant MRSA. Among five multilocus sequence types identified, ST8 (72.7%) and ST5 (22.7%) were most common and livestock-associated MRSA ST398 was assigned to one pork isolate. Eleven spa types were represented, predominately t008 (43.9%) and t2031 (22.7%). All four types of meats harbored t008, whereas t2031 was recovered from turkey only. The majority of MRSA (84.8%) possessed SCCmec IV and 62.1% harbored Panton-Valentine leukocidin. Pulsed-field gel electrophoresis showed that all ST8 MRSA belonged to the predominant human epidemic clone USA300, and others included USA100 and USA200. We conclude that a diverse MRSA population was present in U.S. retail meats, albeit at low prevalence. Published by Elsevier Ltd.

Retailing is an important component of every country's economic system. The current status and developments in the informization of Chinese retail industry were investigated by using questionnaires and interviews to survey 139 retailers throughout China. The investigation shows that Chinese retailers are in the initial informization stage, and can be classified into different types with corresponding informization characteristics. In addition, the survey identified the key problems faced by retailers in the initial stage. Developments in the information technology field were analyzed to identify the key technologies that Chinese retailers should focus on during the informization process. The investigation also shows that the retailers have not arrived at a consensus about information technology adoption, and thus hesitate to use new information technologies, such as the radio frequency identification.

Goulas, A.E.; Kontominas, M.G.

1996-01-01

Food-grade PVC film containing 28.3% dioctyladipate (DOA) plasticizer was used to wrap chicken meat samples, with and without skin, contained in a polystyrene tray. Samples were then irradiated with gamma-radiation [60Co] at doses equal to 4 kGy and 9 kGy corresponding to ''cold pasteurization''. Irraddiation was carried out at 8-10 degrees C and samples were subsequently stored at 4-5 degrees C. Contaminated chicken meat samples were analysed for DOA at intervals between 7 h and 240 h of contact, using an indirect GC method. Identical non-irradiated (control) samples were also analysed for their DOA content. Results showed no statistically significant differences in migrated amounts of DOA between irradiated and non-irradiated samples. Neither were differences observed between samples irradiated at 4 kGy and 9 kGy. This was supported by identical IR spectra recorded for irradiated and non-irradiated samples and leads to the conclusion that, at such intermediate radiation doses ( < or = kGy), the migration characteristics of PVC film are not affected. DOA migration was found to be time dependent, approaching equilibrium after approximately 170 h for the chicken flesh plus skin samples and 120 h for the chicken flesh samples. The amount of DOA migrated into chicken flesh plus skin samples was significantly greater (3.2-22.3 mg/dm2) than that for chicken flesh samples (0.9-8.9 mg/dm2). After 240 h of sample/film contact under refrigeration, loss of DOA was approximately 35.6% for chicken flesh plus skin samples and 14.3% for chicken flesh samples. Sample spoilage, as demonstrated by off-odour development, occurred after approximately 120 h of refrigerated storage. Diffusion coefficients for DOA were calculated and were found to be lower for chicken flesh (1 x 10(-13) than for flesh plus skin (4.4 x 10(-13)) samples

Avians have the unique ability to regenerate cochlear hair cells that are lost due to ototoxins or excessive noise. Many methodological techniques are available to damage the hair cells for subsequent scientific study. A recent method utilizes topical application of an ototoxic drug to the round window membrane. The current study examines the pharmacokinetics of gentamicin in the inner ear of chickens following topical application to the round window membrane or a single systemic high dose given intraperitoneally. Chickens were given gentamicin topically or systemically and survived for 1, 4, 12, 24, or 120 h (controls at 4 and 120 h). Serum and perilymph samples were obtained prior to sacrifice and measured for gentamicin levels. Results revealed higher levels of gentamicin in the perilymph of topically treated chickens than systemically treated chickens, with significant amounts of gentamicin still present in both at the latest survival time of 5 days. As expected, systemically treated chickens had much higher levels of gentamicin in the serum than topically treated chickens. Advantages and disadvantages to each method of drug administration are discussed.

Whole genome sequencing and analysis of Campylobacter coli YH502 from retail chicken reveals a plasmid-borne type VI secretion system

Full Text Available Campylobacter is a major cause of foodborne illnesses worldwide. Campylobacter infections, commonly caused by ingestion of undercooked poultry and meat products, can lead to gastroenteritis and chronic reactive arthritis in humans. Whole genome sequencing (WGS is a powerful technology that provides comprehensive genetic information about bacteria and is increasingly being applied to study foodborne pathogens: e.g., evolution, epidemiology/outbreak investigation, and detection. Herein we report the complete genome sequence of Campylobacter coli strain YH502 isolated from retail chicken in the United States. WGS, de novo assembly, and annotation of the genome revealed a chromosome of 1,718,974 bp and a mega-plasmid (pCOS502 of 125,964 bp. GC content of the genome was 31.2% with 1931 coding sequences and 53 non-coding RNAs. Multiple virulence factors including a plasmid-borne type VI secretion system and antimicrobial resistance genes (beta-lactams, fluoroquinolones, and aminoglycoside were found. The presence of T6SS in a mobile genetic element (plasmid suggests plausible horizontal transfer of these virulence genes to other organisms. The C. coli YH502 genome also harbors CRISPR sequences and associated proteins. Phylogenetic analysis based on average nucleotide identity and single nucleotide polymorphisms identified closely related C. coli genomes available in the NCBI database. Taken together, the analyzed genomic data of this potentially virulent strain of C. coli will facilitate further understanding of this important foodborne pathogen most likely leading to better control strategies. The chromosome and plasmid sequences of C. coli YH502 have been deposited in GenBank under the accession numbers CP018900.1 and CP018901.1, respectively.

Full Text Available Chicken is the most common poultry species and is important to human societies. Tibetan chicken (Gallus gallus domesticus is a breed endemic to China that is distributed mainly on the Qinghai-Tibet Plateau. However, its origin has not been well characterized. In the present study, we sequenced partial mitochondrial DNA (mtDNA control region of 239 and 283 samples from Tibetan and Sichuan indigenous chickens, respectively. Incorporating 1091 published sequences, we constructed the matrilineal genealogy of Tibetan chickens to further document their domestication history. We found that the genetic structure of the mtDNA haplotypes of Tibetan chickens are dominated by seven major haplogroups (A-G. In addition, phylogenetic and network analyses showed that Tibetan chickens are not distinguishable from the indigenous chickens in surrounding areas. Furthermore, some clades of Tibetan chickens may have originated from game fowls. In summary, our results collectively indicated that Tibetan chickens may have diverged from indigenous chickens in the adjacent regions and hybridized with various chickens.

Percentage Retail Mark-Ups

A common assumption in the literature on the double marginalization problem is that the retailer can set his mark-up only in the second stage of the game after the producer has moved. To the extent that the sequence of moves is designed to reflect the relative bargaining power of the two parties it is just as plausible to let the retailer move first. Furthermore, retailers frequently calculate their selling prices by adding a percentage mark-up to their wholesale prices. This allows a retaile...

Dose determination in irradiated chicken meat by ESR method

International Nuclear Information System (INIS)

Polat, M.

1996-01-01

In this work, the properties of the radicals produced in chicken bones have been investigated by ESR technique to determine the amount of dose applied to the chicken meats during the food irradiation. For this goal, the drumsticks from 6-8 weeks old chickens purchased from a local market were irradiated at dose levels of 0; 2; 4; 6; 8 and 10 kGy. Then, the ESR spectra of the powder samples prepared from the bones of the drumsticks have been investigated. Unirradiated chicken bones have been observed to show a weak ESR signal of single line character. CO-2 ionic radicals of axial symmetry with g=1.9973 and g=2.0025 were observed to be produced in irradiated samples which would give rise to a three peaks ESR spectrum. In addition, the signal intensities of the samples were found to depend linearly on the irradiation dose in the dose range of 0-10 kGy. The powder samples prepared from chicken leg bones cleaned from their meats and marrow and irradiated at dose levels of 1, 2, 3, 4, 5, 6, B, 10, 12,14, 16, 1B, 20 and 22 kGy were used to get the dose-response curve. It was found that this curve has biphasic character and that the dose yield was higher in the 12-1B kGy dose range and a decrease appears in this curve over 18 kGy. The radical produced in the bones were found to be the same whether the irradiation was performed after stripping the meat and removing the marrow from the bone or before the stripping. The ESR spectra of both irradiated and non irradiated samples were investigated in the temperature range of 100 K-450 K and changes in the ESR spectra of CO-2 radical have been studied. For non irradiated samples (controls). the signal intensities were found to decrease when the temperature was increased. The same investigation has been carried out for irradiated samples and it was concluded that the signal intensities relative to the peaks of the radical spectrum increase in the temperature range of 100 K-330 K, then they decrease over 330 K.

To explore the effect of modified atmosphere packaging and antioxidants on the physicochemical characteristics of irradiated pre-processed chicken, the pre-processed chicken was added antioxidants first, and then packaged in common, vacuum and gas respectively, and finally irradiated at 5 kGy dosage. All samples was stored at 4 ℃. The pH, TBA, TVB-N and color deviation were evaluated after 0, 3, 7, 10, 14, 18 and 21 d of storage. The results showed that pH value of pre-processed chicken with antioxidants and vacuum packaged increased with the storage time but not significantly among different treatments. The TBA value was also increased but not significantly (P > 0.05), which indicated that vacuum package inhibited the lipid oxidation. TVB-N value increased with storage time, TVB-N value of vacuum package samples reached 14.29 mg/100 g at 21 d storage, which did not exceeded the reference indexes of fresh meat. a * value of the pre-processed chicken of vacuum package and non-oxygen package samples increased significantly during storage (P > 0.05), and chicken color kept bright red after 21 d storage with vacuum package It is concluded that vacuum packaging of irradiated pre-processed chicken is effective on ensuring its physical and chemical properties during storage.

To evaluate the residual target tissues for better monitoring of amantadine abuse in broiler chickens, 22-day-old commercial Arbor Acres broiler chickens were, respectively, fed with 10, 20, and 40 mg/kg of amantadine for five consecutive days. Plasma, breast, and liver tissue samples from the chickens were collected 0, 4, 16, 24, 48, 96, 144, and 312 h after amantadine withdrawal. The high-performance liquid chromatography-tandem mass spectrometry method was used to detect the concentrations of amantadine. The highest concentration was found in the chicken liver and it took the longest time for amantadine to vanish by metabolism. In the high-dose group, amantadine residues were still detected 312 h after amantadine withdrawal. As the amantadine dose increased, amantadine residues in the chicken liver were more slowly to disappear than in other tissues. Even if approximately the same concentration of amantadine residues was found in chicken breast and plasma samples, it took a shorter time before the residues were eliminated. In the medium- and high-dose groups, the concentrations of amantadine residues in chicken liver samples were substantially higher than those in chicken breast and plasma samples, and it took more time to eliminate them. Therefore, the chicken liver can be used as a target tissue to detect illegal use of amantadine. © 2017 John Wiley & Sons Ltd.

Full Text Available Immunosuppression of commercial chickens is a serious animal health and economic problem in the poultry industry. The major causes of the immunosuppression are viruses that suppress transcription of interferon genes, especially interferon alpha. There is a need for monitoring immunosuppression in commercially bred chickens. For this purpose, the absolute abundance of interferon alpha transcripts can be measured in blood of chickens by a suitable assay. Such an assay was used to estimate abundance of chicken interferon alpha in a sample of splenic cells induced with polyinosinic polycytidylic acid. The abundance measured was 29 ± 2 attomoles/µg total RNA. This assay can be performed in microtitre plates using samples collected from chickens in poultry houses.

Full Text Available Sustainability is a key requirement for business success and is often regarded a competitive advantage if strategically managed. Sustainability-mature organisations look to their value chains where the retailer-supplier collaboration becomes critical in embedding sustainability. With this in mind, it is important to monitor retailer-supplier collaboration to determine whether it is effective. To facilitate this monitoring, the UN Global Compact Supply Chain Sustainability: A Guide for Continuous Improvement was consulted. The research question aimed to determine the progress of a prominent South African retailer regarding their sustainable supply chain management (SSCM and collaboration with suppliers. Therefore, this study attempts to apply the Supplier Engagement Continuum, extracted from the UN Global Compact Supply Chain Sustainability: A Guide for Continuous Improvement, in order to determine how the retailer is progressing in sustainable supply chain management. The qualitative and exploratory nature of the study necessitated a case study research design, while the technique of purposive sampling was used to select the sample of three suppliers. Data was collected by means of semi-structured interviews facilitated by an interview guide, and data analysis was conducted with Atlas.ti software. It was found that the retailer’s sustainable supply chain management can only be located on level one of the continuum. Supply chain sustainability in organisations lack the theoretical foundation of what sustainability really is. Therefore, the model was amended and an additional level was added to incorporate the education of sustainability.

Behnam Abasht

Full Text Available This study was conducted to characterize metabolic features of the breast muscle (pectoralis major in chickens affected with the Wooden Breast myopathy. Live birds from two purebred chicken lines and one crossbred commercial broiler population were clinically examined by manual palpation of the breast muscle (pectoralis major at 47-48 days of age. Metabolite abundance was determined by gas chromatography/mass spectrometry (GC/MS and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS using breast muscle tissue samples from 16 affected and 16 unaffected chickens. Muscle glycogen content was also quantified in breast muscle tissue samples from affected and unaffected chickens. In total, levels of 140 biochemicals were significantly different (FDR1.3 or <0.77 between affected and unaffected chickens. Glycogen content measurements were considerably lower (1.7-fold in samples taken from Wooden Breast affected birds when compared with samples from unaffected birds. Affected tissues exhibited biomarkers related to increased oxidative stress, elevated protein levels, muscle degradation, and altered glucose utilization. Affected muscle also showed elevated levels of hypoxanthine, xanthine, and urate molecules, the generation of which can contribute to altered redox homeostasis. In conclusion, our findings show that Wooden Breast affected tissues possess a unique metabolic signature. This unique profile may identify candidate biomarkers for diagnostic utilization and provide mechanistic insight into altered biochemical processes contributing to tissue hardening associated with the Wooden Breast myopathy in commercial chickens.

Irradiation could effectively control lactobacillus of fermented spicy chicken feet and extend its shelf life. Sensory evaluation standard of fermented spicy chicken feet was established to study the sensory change after irradiation according to related standards and research results. Color and shape (weight 30%), scent (weight 30%), texture and taste (weight 40%) were selected as sensory evaluation items. The sensory evaluation results after irradiation 3 days didn't show significance difference among control, 3, 5, 8 and 12 kGy irradiated samples, and the sensory evaluation score of 10 kGy irradiated sample was much higher then other sample groups. The results after irradiation 11d were almost as same as 3d results. It is indicated that the sensory quality of fermented spicy chicken feet would not destroyed by irradiation, and suitable dosage of irradiation may promote the sensory quality of fermented spicy chicken feet.

Full Text Available Commerce, as an important industry of any national economy, is a socially important complex of activities, which has to correspond to the general level of development and civilization of the community it serves. Considering this, the essential priorities commercial activity will turn to are represented by the increased power that consumers get through better informing, the assurance of a better connection between retail and innovation, more equitable and sustainable commercial relationships along the purchase chain, the improvement of retail services accessibility, the creation of a better work environment through the better correlation between employers’ needs and employers’ competences. Retail is permanently adapting to the changing market conditions, remaining a high competitive sector. Modern buyer is hurried, more mobile, better informed; more concerned about health, environment, comfort and aesthetics issues, more demanding in terms of quality and level of customization. Population migration, urbanization, and ageing, its absolute decrease, the average households size reduction, are all demographic trends to which retail must provide an appropriate answer. Retail businesses operating costs tend to increase, while buyers are warier under the impact of the global financial crisis, which will put additional pressure on profit margins.

The microbiological quality of 351 samples of nine types of spices including black pepper, caraway, cinnamon, cow parsnip, curry powder, garlic powder, red pepper, sumac, and turmeric, collected from retail shops in Tehran during 2007, was determined. The numbers of aerobic mesophilic bacteria, Escherichia coli, and molds exceeded Iran's National Standard limits, at 63.2% (>5 × 10(5) CFU/g), 23.4% (>0.3 MPN/g), and 21.9% (>5 × 10(3) CFU/g) of the studied samples, respectively. Coliform contamination was more than 10(3) MPN/g in 24.8% of samples. High contamination of retail spices is considered an indication of environmental or fecal contamination due to unhygienic practices in their production. Use of spices with high microbial content could increase the chance of food spoilage and transmission of foodborne pathogens. Accordingly, application of food safety measurements to reduce microbial counts in spices is strongly recommended.

The purpose of this study was to investigate the microbiological quality of liver pâté. During 2012-13, a total of 870 samples, unrelated to the investigation of food-poisoning outbreaks, were collected either at retail (46%), catering (53%) or the point of manufacture (1%) and were tested using standard methods to detect Salmonella spp. or Campylobacter spp., and to enumerate for Listeria spp., including Listeria monocytogenes, Clostridium perfringens, coagulase-positive staphylococci including Staphylococcus aureus, Bacillus spp., including Bacillus cereus, Escherichia coli, Enterobacteriaceae, and aerobic colony counts (ACCs). Seventy-three percent of samples were of satisfactory microbiological quality, 18% were borderline and 9% unsatisfactory. Salmonella spp. or Campylobacter spp. was not recovered from any sample. The most common causes of unsatisfactory results were elevated ACCs (6% of the samples) and high Enterobacteriaceae counts (4% of samples). The remaining unsatisfactory results were due to elevated counts of: E. coli (three samples); B. cereus (one sample at 2·6 × 105 cfu/g); or L. monocytogenes (one sample at 2·9 × 103 cfu/g). Pâté from retail was less likely to be contaminated with L. monocytogenes than samples collected from catering and samples from supermarkets were of significantly better microbiological quality than those from catering establishments.

Chickens at selected points in the slaughter process and after slaughter on the dressing line in poultry plants were sampled and analyzed for Salmonella. These chickens came from the northeast part of Poland. The examinations were carried out in quarters I, II, III, and IV of 1999. All the birds were determined to be healthy by a veterinary inspection. Swab samples were taken from the cloaca after stunning and from the skin surface and body cavity of the whole bird after evisceration, after rinsing at the final rinse station but before chilling in the spin-chiller, and after cooling in the continuous cooling plant at the end of the production day. In 1999, 400 whole chickens were examined. The percentage of these 400 chickens from which Salmonella spp. were isolated was relatively high (23.75%; Salmonella-positive results were observed in 95 cases). Salmonella spp. were found after stunning in 6% of the chickens (6 of 100 samples), after evisceration in 24% (24 of 100), before cooling in 52% (52 of 100), and after cooling in 13% (13 of 100). These results show that Salmonella spp. were found more often at some processing points than at others. The lowest Salmonella spp. contamination rate (6%) for slaughter birds was found after stunning, and the highest contamination rate was found before chilling (52%). The serological types of Salmonella spp. isolated from whole chickens were Salmonella Enteritidis, Salmonella Typhimurium, Salmonella Saintpaul, Salmonella Agona, and Salmonella Infantis. The results of these investigations indicate that Salmonella Enteritidis is the dominant serological type in infections of slaughter chickens, as it is in many countries.

Full Text Available Background: Cross-contamination of foodborne pathogens from undercooked poultry meat to ready-to-eat food has been shown to be responsible for a number of foodborne disease outbreaks. Various studies have indicated that bacterial cross-contamination occurs during food preparation where bacteria present on food contact other surfaces and cause illness. Objectives: This study evaluated the ability of bacteria to survive and cross-contaminate other foods during the preparation of fresh chicken. Salmonella spp. cross-contamination from chicken to cucumber and utensils under various food handling scenarios was determined. Methods: Two scenarios were tested: in scenario 1, cutting board and knife used for cutting chicken without washing step were sampled. In scenario 2, cutting board and knife was washed with tap water separately after cutting chicken, and subsequently used for cutting cucumber. In scenario 1, chicken, cutting board, knife, and hands were sampled, and in scenario 2, cucumber was tested. Fluorescent in situ hybridization (FISH method, using published Salmonella specific gene probes was used for Salmonella detection in samples taken from cross-contamination scenarios. A culture-based detection by Hektoen enteric agar was used for the confirmation of Salmonella species. Results: All the samples analyzed were found to be positive for Salmonella spp. with different contamination levels. These results were further confirmed by culture based method. In scenario 1, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in all four samples (chicken, cutting board, knife and hands. A high contamination level was observed in chicken samples in comparison to samples collected from cutting board, knife and hands. In scenario 2, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in the cucumber with very low contamination level. Salmonella Enterica was also detected by Sal-3 and Sapath-3 in both scenarios but

Campylobacteriosis, the most frequent bacterial enteric disease, shows a clear yet unexplained seasonality. The study purpose was to explore the influence of seasonal fluctuation in the contamination of and in the behaviour exposures to two important sources of Campylobacter on the seasonality of campylobacteriosis. Time series analyses were applied to data collected through an integrated surveillance system in Canada in 2005-2010. Data included sporadic, domestically-acquired cases of Campylobacter jejuni infection, contamination of retail chicken meat and of surface water by C. jejuni, and exposure to each source through barbequing and swimming in natural waters. Seasonal patterns were evident for all variables with a peak in summer for human cases and for both exposures, in fall for chicken meat contamination, and in late fall for water contamination. Time series analyses showed that the observed campylobacteriosis summer peak could only be significantly linked to behaviour exposures rather than sources contamination (swimming rather than water contamination and barbequing rather than chicken meat contamination). The results indicate that the observed summer increase in human cases may be more the result of amplification through more frequent risky exposures rather than the result of an increase of the Campylobacter source contamination.

A study was carried out to determine suitable dose, microbiological counts including pathogens and sensory evaluation of pre-cooked chicken meat products in assessing the acceptability of irradiated pre-cooked chicken meat products. Packed pre-cooked chicken sausages and burger samples (sealed individually in plastic-polyethylene pouches) were irradiated at the following doses: 2.5 kGy, 3.5 kGy and 5.5 kGy using 60 Co gamma irradiation at MINTec-Sinagama. Acceptability of the sausages was determined through sensory evaluation by 30 members of untrained panelists comprising staff of Malaysian Nuclear Agency. A 5-points hedonic rating scale was used. The attributes evaluated were taste, texture, chewiness, juiciness, aroma, colour, shape and overall acceptance. Samples irradiated with dose of 5.5 kGy were the most acceptable, followed by samples irradiated at 3.5 kGy and 10 kGy. Irradiation at doses up to 3.5 kGy render undetectable microorganisms/fungi and pathogens (faecal coliforms, Salmonella sp., Escherichia coli and Staphylococcus aureus) in pre-cooked chicken sausages, and doses up to 5.5 kGy for pre-cooked chicken burgers

Chicken breast muscle was cooked by boiling, baking, sautéing, or deep-frying. Cooked samples were mixed with ferric iron and either extracted with acid or digested with pepsin and pancreatin. Total and ferrous dialyzable iron was measured after extraction or digestion and compared to raw chicken samples. For uncooked samples, dialyzable iron was significantly enhanced after both extraction and digestion. All cooking methods led to markedly reduced levels of dialyzable iron both by extraction and digestion. In most cooked, digested samples dialyzable iron was no greater than the iron-only (no sample control. Cooked samples showed lower levels of histidine and sulfhydryls but protein digestibility was not reduced, except for the sautéed sample. The results showed that, after cooking, little if any dialyzable iron results from digestion of muscle proteins. Our research indicates that, in cooked chicken, residual acid-extractable components are the most important source of dialyzable iron.

Full Text Available : Chilled and frozen chicken breast and thigh meat were stored at +4±1 oC and - 20±1 oC, respectively. Maillard reaction between ribose and meat proteins of the chicken samples was initiated. The changes in the ribose-induced Maillard reaction rate during chilled and frozen storage of chicken meat were evaluated on the bases of corrected absorbance values (A420* and bovine melanoidin equivalent values (mg BME/g. Application of BME as a measure of ribose-induced Maillard reaction rate enables comparability of the data obtained by different spectrophotometers. It was found that the BME values of chicken meat frozen stored for more than 15 days were significantly (P<0.05 lower than BME values of chilled-stored samples. According to the suggested threshold limit values the chicken thigh and breast meat with BME values lower than 30 mg BME/g and 51 mg BME/g, respectively could be classified as frozen-thawed.

Salmonellae infections in deep-frozen roasting chicken can be dealt with by ionising radiation as this process involves hardly any heating of the product. Deep-frozen chickens irradiated with doses up to 800 krad were stored at -30 0 C for two years and were regularly submitted to sensory tests. There was no significant difference in quality between the irradiated samples and the non-irradiated controls. (orig.) [de

To evaluate Ovo-transferrin (OTF), a positive acute-phase protein in chickens, as a diagnostic biomarker of selected bacterial infections we checked the performance of a commercial Chicken-OTF-ELISA (ICL, Inc., Portland, OR, USA) by analytical and overlap performances using two groups of serum samples obtained from 26 Gallibacterium anatis-infected and 20 Streptococcus zooepidemicus-infected brown layer chickens. In addition, sera from 14 apparently healthy and 19 negative control chickens were analysed in the Gallibacterium group whereas sera from 20 healthy and 11 negative control chickens from the Streptococcus group were analysed. All calibration curves revealed high coefficients of determination (≥ 0.97) between optical density (OD 450nm) and concentrations of OTF (mg/ml). OTF concentrations in high, medium and low pools (made of sera from a combination of infected and/or non-infected birds) were >6.4, >3.8 to 6.7, >3.5 to chickens (Gallibacterium, 4.4 ± 0.3 mg/ml; Streptococcus, 3.2 ± 0.4 mg/ml) compared with negative controls (1.7 ± 0.1 mg/ml) (P Chicken-OTF-ELISA can be used to measure reproducible serum OTF concentrations in brown layer chickens as a response to G. anatis infections, whereas an adjustment of dilution process is proposed to optimize to use in S. zooepidemicus-infected chickens.

The factors of retail brand positioning

Full Text Available This paper gives the basic characteristics of a retail process as a function of the development of a successful brand. The retail network is continuously progressing, developing its abilities, successfully adjusting to its environment, and which is the most important it is persistently following wishes and needs of its consumers, and is satisfying them through high-quality offers. The retail network is relatively a new business structure, which has a great potential for competitive advantage. Once, prestigious partners to retailers, which have represented successful brands, they are often perceived to be stripped of rank and to come back at the level of common suppliers. Also, the suppliers' brands have no longer the position as they had, their status has decreased and their former power is gone, as a more superior, compared to the retailers. The inertia, enjoying 'the old glory', thinking in the manner of the same well-established formula as well as the inability to adjust themselves to the changes occurring among consumers have led the majority of the brands to be stuck in the past. The companies have to stop this increasing phenomenon, if they do not want to face in the near future, even more dramatic and more harmful consequences. Since the main aim of the research, performed in this work, was to determine the importance of retail brand positioning, the retail environment was analyzed, with special emphases on the consumer role in retail, and factors of successful retail activities. As a special aspect of successful retail, the environment of retail place was determined and within this, the effects of the retail places' atmosphere. For setting the retail strategy framework, the following basic entities are observed: product, price, exclusivity, quick response, information technology, price strategy, logistics and competitiveness. .

Strategies for the improvement of rural chicken production in Ghana

International Nuclear Information System (INIS)

Awuni, J.A.

2002-01-01

Rural poultry production systems in Ghana and in Africa as a whole are based on the scavenging indigenous domestic fowl (Gallus domesticus), the predominant species in the poultry sector. In most African countries scavenging chicken have no regular health control programmes, may or may not have shelter and usually have to scavenge around for their nutritional requirements. In Ghana, the total poultry population is estimated to be over 20 million with 80% of this being rural scavenging chicken. Out of this population, 80% is lost annually due to outbreaks of Newcastle disease and a number of other causes. Reported here are the results of field surveys conducted in the wet and dry seasons in two selected ecological zones (Forest and Coastal) to establish the constraints to improvement of rural chicken production in the country. The survey covered only women farmers who engaged in rural poultry production. During the course of the survey, chicken flocks as well as chicken houses were examined for ectoparasites. Faecal samples were collected for laboratory diagnosis of endo-parasite infestation, as well as serum samples for analysis of antibodies using immunoassay techniques. The survey revealed that Newcastle disease still remains the most important disease of the scavenging rural chickens. (author)

To identify the use of ultra-processed foods - vectors of salt, sugar and fats - in the Norwegian diet through an assessment of food sales. Sales data from a representative sample of food retailers in Norway, collected in September 2005 (n 150) and September 2013 (n 170), were analysed. Data consisted of barcode scans of individual food item purchases, reporting type of food, price, geographical region and retail concept. Foods were categorized as minimally processed, culinary ingredients, processed products and ultra-processed. Indicators were share of purchases and share of expenditure on food categories. Six geographical regions in Norway. The barcode data included 296 121 observations in 2005 and 501 938 observations in 2013. Ultra-processed products represented 58·8 % of purchases and 48·8 % of expenditure in 2013. Minimally processed foods accounted for 17·2 % of purchases and 33·0 % of expenditure. Every third purchase was a sweet ultra-processed product. Food sales changed marginally in favour of minimally processed foods and in disfavour of processed products between 2005 and 2013 (χ 2 (3)=203 195, Pprocessed products accounted for the majority of food sales in Norway, indicating a high consumption of such products. This could be contributing to rising rates of overweight, obesity and non-communicable diseases in the country, as findings from other countries indicate. Policy measures should aim at decreasing consumption of ultra-processed products and facilitating access (including economic) to minimally processed foods.

Results are presented indicating a linear relationship between irradiation dose (10–60 kGy) and the quantity of 2-dodecylcyclobutanone produced in irradiated frozen (-46°C) chicken meat. 2-Dodecylcyclobutanone was found in chicken meat sterilized (at -40°C) by gamma and electron beam irradiation 12 years previously and used for toxicity clearance. After freeze-drying the irradiated chicken samples still contained 2-dodecylcyclobutanone indicating that it was present in the diets tested. The compound was not detected in chicken meat sterilized by thermal processing 13 years ago. In addition, there was evidence that 2-tetradecylcyclobutanone was also present in the irradiation sterilized samples

Ono, K; Yamamoto, K

1999-03-15

To determine the source of food contamination with Campylobacter jejuni, we investigated retail meat, a chicken processing plant and a broiler farm. C. jejuni was found in domestic retailed poultry (45.8%) and imported poultry (3.7%), but not in beef or pork. In the poultry processing plant, there is significant contamination with C. jejuni in chicken carcasses, equipment and workers' hands. This contamination increases during the defeathering and evisceration processes. RAPD analysis shows that contamination with C. jejuni is of intestinal origin. In a broiler farm, C. jejuni was first isolated from a faecal sample of broiler chicken after the 20th day of age. Two weeks later, all birds in this farm became C. jejuni positive. RAPD analysis indicated that C. jejuni spread rapidly from one broiler flock to the other flocks on the farm.

Consumer Attitudes Toward Storing and Thawing Chicken and Effects of the Common Thawing Practices on Some Quality Characteristics of Frozen Chicken

2016-01-01

In this study, a survey was conducted to both evaluate the consumers’ general attitudes for purchasing and storing the raw chicken and determine the thawing practices used for defrosting frozen chicken at home. About 75% of the consumers indicated purchasing chicken meat at least once a week or more. Furthermore, the majority (82.16%) of those who stored at least a portion of the raw chicken stated freezing the raw chicken meat at home. Freezing the chicken meat was considered to have no effect on the quality by 43.49% of the consumers while 56.51% thought that freezing had either negative or positive effects on the quality. The survey study indicated that top five most commonly used thawing practices included thawing on the kitchen counter, thawing in the refrigerator, thawing in the warm water, thawing in the microwave, and thawing under tap water. In addition, an experimental study was conducted to determine the effects of these most commonly used thawing practices on some quality characteristics of the chicken meat including pH, drip loss, cooking loss, color analysis and textural profile analysis. Although, L* value for thawing on the kitchen counter was the lowest, after cooking, none of the thawing treatments have a significant effect on the color values. Thawing in the microwave produced the highest drip loss of 3.47% while the lowest drip loss of 0.62% was observed with thawing in the refrigerator. On the other hand, thawing in the microwave and refrigerator caused the lowest cooking loss values of 18.29% and 18.53%, respectively. Nevertheless, there were no significant differences among textural parameter values of the defrosted and then cooked samples using the home based thawing practices, indicating similar quality characteristics among the samples.

In addition, an experimental study was conducted to determine the effects of these most commonly used thawing practices on some quality characteristics of the chicken meat including pH, drip loss, cooking loss, color analysis and textural profile analysis. Although, L* value for thawing on the kitchen counter was the lowest, after cooking, none of the thawing treatments have a significant effect on the color values. Thawing in the microwave produced the highest drip loss of 3.47% while the lowest drip loss of 0.62% was observed with thawing in the refrigerator. On the other hand, thawing in the microwave and refrigerator caused the lowest cooking loss values of 18.29% and 18.53%, respectively. Nevertheless, there were no significant differences among textural parameter values of the defrosted and then cooked samples using the home based thawing practices, indicating similar quality characteristics among the samples.

In this study, a survey was conducted to both evaluate the consumers' general attitudes for purchasing and storing the raw chicken and determine the thawing practices used for defrosting frozen chicken at home. About 75% of the consumers indicated purchasing chicken meat at least once a week or more. Furthermore, the majority (82.16%) of those who stored at least a portion of the raw chicken stated freezing the raw chicken meat at home. Freezing the chicken meat was considered to have no effect on the quality by 43.49% of the consumers while 56.51% thought that freezing had either negative or positive effects on the quality. The survey study indicated that top five most commonly used thawing practices included thawing on the kitchen counter, thawing in the refrigerator, thawing in the warm water, thawing in the microwave, and thawing under tap water.

Full Text Available The chicken is an important agricultural animal and model for developmental biology, immunology and virology. Excess fat accumulation continues to be a serious problem for the chicken industry. However, chicken adipogenesis and obesity have not been well investigated, because no chicken preadipocyte cell lines have been generated thus far. Here, we successfully generated two immortalized chicken preadipocyte cell lines through transduction of either chicken telomerase reverse transcriptase (chTERT alone or in combination with chicken telomerase RNA (chTR. Both of these cell lines have survived >100 population doublings in vitro, display high telomerase activity and have no sign of replicative senescence. Similar to primary chicken preadipocytes, these two cell lines display a fibroblast-like morphology, retain the capacity to differentiate into adipocytes, and do not display any signs of malignant transformation. Isoenzyme analysis and PCR-based analysis confirmed that these two cell lines are of chicken origin and are free from inter-species contamination. To our knowledge, this is the first report demonstrating the generation of immortal chicken cells by introduction of chTERT and chTR. Our established chicken preadipocyte cell lines show great promise as an in vitro model for the investigation of chicken adipogenesis, lipid metabolism, and obesity and its related diseases, and our results also provide clues for immortalizing other avian cell types.

2014-02-01

The CALiPER program first began investigating LED lamps sold at retail stores in 2010, purchasing 33 products from eight retailers and covering six product categories. The findings revealed a fragmented marketplace, with large disparities in performance of different products, accuracy of manufacturer claims, and offerings from different retail outlets. Although there were some good products, looking back many would not be considered viable competitors to other available options, with too little lumen output, not high enough efficacy, or poor color quality. CALiPER took another look in late 2011purchasing 38 products of five different types from nine retailers and the improvement was marked. Performance was up; retailer claims were more accurate; and the price per lumen and price per unit efficacy were down, although the price per product had not changed much. Nonetheless, there was still plenty of room for improvement, with the performance of LED lamps not yet reaching that of well-established classes of conventional lamps (e.g., 75 W incandescent A19 lamps). Since the second retail lamp study was published in early 2012, there has been substantial progress in all aspects of LED lamps available from retailers. To document this progress, CALiPER again purchased a sample of lamps from retail stores 46 products in total, focusing on A19, PAR30, and MR16 lamps but instead of a random sample, sought to select products to answer specific hypotheses about performance. These hypotheses focused on expanding ranges of LED equivalency, the accuracy of lifetime claims, efficacy and price trends, as well as changes to product designs. Among other results, key findings include: There are now very good LED options to compete with 60 W, 75 W, and 100 W incandescent A19 lamps, and 75 W halogen PAR30 lamps. MR16 lamps have shown less progress, but there are now acceptable alternatives to 35 W, 12 V halogen MR16 lamps and 50 W, 120 V halogen MR16 lamps for some applications. Other

Full Text Available The paper presents the research results of effects of retail brands of consumer goods on the market share they have in Serbia. In particular, the research includes the impact of the retail format on the growth or decrease in market share. The data were obtained from market retailing research of consumer goods on the Internet and the research carried out by the GFK agency. The study used a statistical method of data processing by the method of descriptive statistics. The survey showed that the Serbian retail market is still underdeveloped, and that the strongest impact on the market share of retail chain stores of consumer goods has the size of the retail network, as well as a strong dominance of traditional trade in comparison to organized one. The retail market in Serbia has a long period of consolidation forthcoming and also taking over such a status that organized trades or TOP 10 retail chains have already had in the most developed countries. The market share of TOP 10 retail chains in Serbia is now at the level slightly bigger than 30%, while those in developed market economies have a market share moving up to 75%.

Scott Teeter, Jerold; Meyerhoff, R.D.

2003-01-01

Tylosin, a fermentation-derived macrolide antibiotic, was tested to determine its aerobic degradation rate in cattle, chicken, and swine excreta. For chicken, excreta from a hen administered 14 C-tylosin as part of a metabolism study were used. For cattle and swine, 14 C-tylosin was added to control excreta. The formation of 14 C volatile breakdown products and 14 CO 2 was not observed throughout the study. Material balance for the cabon-14 label ranged between 94% and 104%. Initial, day-0, concentrations of tylosin-A averaged 119.52±4.39, 35.01±1.34, and 62.82±2.11 μg/g (dry weight basis) for cattle, chicken, and swine excreta samples, respectively. After 30 days, samples averaged 4.16±0.69 and 4.11±0.69 μg/g tylosin-A in cattle and swine excreta, respectively. No residues of tylosin-A or its factors were apparent in the chicken excreta samples after 30 days of incubation. In each case, tylosin declined to less than 6.5% of the initial level after 30 days. Calculated first-order half-lives under the test conditions were 6.2 days, <7.6 days, and 7.6 days for cattle, chicken, and swine excreta, respectively. The results indicate that tylosin residues degrade rapidly in animal excreta. Therefore, tylosin residues should not persist in the environment

This is the first statewide census of the product availability, price promotions, and product messaging of vape shops. A comprehensive list of New Hampshire vape shops was developed through a previously validated online search method. Store audits were conducted in 55 stores between January and February 2016 using the Vape Shop Standardized Tobacco Assessment for Retail Settings (V-STARS). Modifiable devices and cig-alikes were sold in 92.6% and 14.6% of stores, respectively. Cross-product promotions with tobacco products were rare, and messaging promoting e-cigarettes as effective cessation devices was found in 27.3% of all stores. Candy/fruit and menthol e-liquids were most commonly found in stores, and sampling of products was available in 83.6% of stores. Ten (18.2%) stores did not have a minimum age sign posted, and self-service sampling displays were available in about one-fifth of stores. Using V-STARS to conduct retail assessments of vape shops is feasible and is important for assessing the changing retail environment of vape shops. Vape shops distinguish themselves from traditional tobacco product retailers and offer a variety of products to customize a consumer's experience. Regulations and effective enforcement ensuring accurate health messages is essential.

1998-12-01

Full Text Available Microbial hazards associated with street-vended grilled chicken intestine (isaw were studied. Grilling of isaw effected ≥89.00% decrease in the total microbial load of the sample. Cooked isaw contained about 105-106 cfu/g aerobic plate counts and 103-104 MPN/g coliform counts. Salmonella per 25 g sample was isolated from cooked isaw samples. Grilling eliminated Staphylococcus aureus and Listeria monocytogenes cells initially present in pre-cooked samples. Different sauces of isaw showed increasing numbers of total aerobic microorganisms and coliform during vending operations. The total plate counts and coliform counts of the sour sauce, which ranged from 103-105 cfu/g and 101 MPN/g, respectively, were observed to be lower than those found in the sweet sauce. Sources of microbial contaminants of grilled chicken isaw included the natural flora of the raw materials, contaminations from food-contact surfaces, bamboo skewers, and the hands of the food handlers. Among the critical control points identified in the street-vending operation of chicken isaw were the control of time and temperature during cooking and hold-on periods during vending operations.

Sub-therapeutic doses of antimicrobial agents are administered routinely to poultry to aid growth and to prevent disease, with prolonged exposure often resulting in bacterial resistance. Crossover of antibiotic resistant bacteria from poultry to humans poses a risk to human health. In this study, 17 chicken samples collected from a vendor operating in an informal settlement in the Cape Town Metropolitan area, South Africa were screened for antimicrobial-resistant Gram-negative bacilli using the Kirby Bauer disk diffusion assay. IN TOTAL, SIX ANTIBIOTICS WERE SCREENED: ampicillin, ciprofloxacin, gentamicin, nalidixic acid, tetracycline and trimethoprim. Surprisingly, Klebsiella ozaenae was identified in 96 and K. rhinoscleromatis in 6 (n=102) of the samples tested. Interestingly, ∼40% of the isolated Klebsiella spp. showed multiple resistance to at least three of the six antibiotics tested. Klebsiella ozaenae and K. rhinoscleromatis cause clinical chronic rhinitis and are almost exclusively associated with people living in areas of poor hygiene.

Competition in the retail gasoline industry

Science.gov (United States)

Brewer, Jedidiah

2007-05-01

This dissertation examines competition in the retail gasoline industry. The first chapter highlights the importance of gasoline in modern society, introduces my work, and places it in the context of the existing academic literature. The second chapter details the institutional structure and profitability of the industry. The vast majority of retail gasoline stations are not directly owned and operated by major oil companies. Instead, most stations are set up under other contractual relationships: lessee-dealer, open-dealer, jobber-owned-and-operated, and independent. Gasoline retailers make relatively low profits, as is the case in many other retail industries, and are substantially less profitable than major oil companies. Gas stations also make less money when retail prices are climbing than when they are falling. As prices rise, total station profits are near zero or negative. When retail prices are constant or falling, retailers can make positive profits. The third chapter describes the entry of big-box stores into the retail gasoline industry over the last decade. The growth of such large retailers, in all markets, has led to a great deal of controversy as smaller competitors with long-term ties to the local community have become less common. I estimate the price impact that big-box stores have on traditional gasoline retailers using cross-sectional data in two geographically diverse cities. I also examine changes in pricing following the entry of The Home Depot into a local retail gasoline market. The results show that big-box stores place statistically and economically significant downward pressure on the prices of nearby gas stations, offering a measure of the impact of the entry of a big-box store. Chapter 4 examines the nature of price competition in markets where some competing retailers sell the same brand. The price effect of having more retailers selling the same brand is theoretically unclear. High brand diversity could give individual retailers

Full Text Available The retail banking sector in South Africa is predominantly characterised by a high face to face interaction and constant product and pricing differentiation. In order for a bank to distinguish itself from other banks in the banking industry, it uses excellence in its service quality to stand out against its competitors. In the study, the researchers adapted the SERVQUAL model to the banking industry. A probability sampling technique was employed for the study. Simple random sampling was employed to test MBA students’ perceptions towards service quality in the banking industry. The findings in the empirical study revealed that MBA students at the university were dissatisfied with the quality of service offerings provided by the retail banks in South Africa. There were quality gaps revealed in tangibles, reliability, empathy, responsiveness and reliability aspects of the service encounters

Hospital-affiliated and hospital-owned retail clinics: strategic opportunities and operational challenges.

Science.gov (United States)

Kaissi, Amer

2010-01-01

Retail clinics have experienced an exponential growth in the last few years. While the majority of retail clinics are freestanding, venture-backed companies affiliated with retail hosts, an increasing number of hospital systems have decided to develop their own retail clinics or partner with existing national companies. Using a stakeholder approach, the purpose of this article is to assess the strategic considerations behind these decisions and the operational challenges associated with them and to use the results to develop a questionnaire that can be applied in future research in a national sample of healthcare executives. We conducted eight in-depth interviews with administrative and clinical leaders in seven hospital systems across the United States that have or had a relationship with retail clinics in the last three years. Our findings show that the hospital systems' association with retail clinics involves two main models: an affiliation with retail chains that operate the clinics and ownership of the clinics with an arms-length relationship with the retail chain. Hospital systems are engaging in these relationships for several strategic reasons: to increase market share through enhanced referrals to physician offices and hospitals, to become closer to consumers, and to experiment with nontraditional ways of delivering health care. Operational challenges included physician resistance and skepticism, poor financial performance, people's perception of retail clinics, staffing issues, and the newness of the business model. Six out of eight respondents thought that hospital affiliation with/ownership of retail clinics is a trend that is here to stay, although many provided caveats and stipulations. Further research is needed to provide more evidence about this emerging way of healthcare delivery.

This investigation aims to study the possibility of using gamma irradiation for microbial decontamination of some chicken meat products (Luncheon, Burger and debonded minced chicken) which are produced by three companies (Halwany Bros.(H)-Faragalla (F) and Egypco (E)). The samples were purchased from local supermarkets and examined for the presence of Salmonella spp. and Staphylococcus aureus. The examination illustrated that all examined samples were positive for Staphylococcus aureus. While Luncheon (F), Burger (H) and debonded minced chicken (E) were only positive for Salmonella spp. Therefore, these product samples were gamma irradiated at 0, 3, 6 and 9 kGy. The effects of radiation treatments and cold storage (5+,-1 degree) on the total volatile basic nitrogen (T.V.B.N.), microbiological quality and sensory properties of samples under investigation were studied. The results indicated that 3kGy dose of gamma irradiation completely destroyed Staphylococcus aureus and Salmonella spp. and caused slight increase in (T.V.B.N.) content for all samples. A gradual increase in total bacteria, molds and yeast and T. V. B. N. during storage were observed, while 6 kGy dose was also sufficient for destroying Salmonella spp. and Staphylococcus aureus in all chicken meat products under investigation without any detectable effects on the sensory properties of these products and increased the shelf-life of luncheon, burger and minced for 8, 4 and 3 weeks respectively as compared with 4, 2 and 1 weeks for control samples

Beef is one of expensive animal protein sources compared to other meats, on the other hand, chicken is cheap animal protein source. Mixing of chicken into beef meatball is possibly performed to decrease production cost. The aim of this study was to detect chicken contamination in beef meatball using Cytochrome b (Cyt b) gene by duplex-PCR. Sample was designed and prepared as follows, 100% of chicken meatball, 100% of beef meatball and serial level of chicken contaminations in beef meatball (1, 5, 10 and 25%, respectively). Isolation of DNA genome from meatball was according to the guideline of gSYNCTM DNA Extraction Kit for animal tissue. The PCR reaction was carried out using KAPA2G Fast Multiplex Mix. This study found that the DNA genome was succesfully extracted. Moreover, chicken contamination in beef meatball was indicated by the presence of 227 bp DNA band on 2% of agarose gels. Current study revealed that duplex-PCR using Cyt b gene as a genetic marker was able to detect chicken contamination in beef meatball until 1% of chicken meat in the sample. It can be effectively used to identify contamination and also authenticate species origin in animal products to protect consumer from undesirable contents in the food.

The food retailing and food service sector is not only an important component of the food marketing channel but is also vital to the United States economy, accounting for more than 7% of the United States gross domestic product in 2001. The business of food retailing and food service is undergoing salient change. The authors argue that the singular force driving this change is the consumer. To understand the linkages in the food marketing channel, this article provides information on the farm-to-retail price spread and the economic forces that influence their magnitude. Examples are given of farm-to-retail price spreads for red meat and dairy industries. In addition, the economics behind the provision of retail services and the growth of the food service industry are discussed. Further, the authors demonstrate that the structure of the food market channel is consumer driven, and present three characteristics of convenience (preparation, delivery, and service) and identify four food distribution channels in terms of convenience (complete convenience, traditional food service, consumer direct, and traditional retail).

Full Text Available Aim: Chicken astroviruses (CAstV are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada. Materials and Methods: Blood samples from 366 indigenous chickens and 92 commercial chicken layers were collected from all parishes of the island and tested for antibodies against CAstV using commercial enzyme-linked immunosorbent assay. Results: The seroprevalence of antibodies against astrovirus was 57.6% (95%, Confidence interval [CI]: 47.4-67.2 in commercial layers and 61.5% (95%, CI: 56.4-66.3 in indigenous chickens. The results show the presence of infection throughout the island. Conclusion: The results show the infection with CAstV in approximately half of the chicken population in Grenada. This is the first report on the prevalence of CAstV in chickens in Grenada and the Caribbean region.

The popularity of electronic cigarettes (e-cigarettes) has spurred the growth of vape shops, but little is known about the retailers who may play an important role in the introduction and dissemination of vape products. In this paper we examine how retailers profile their customers and their perceptions of vaping, and the services their shops provide. Semi-structured interviews were conducted with a convenience sample of retailers (n=77) located across southern California. Open-ended questions were coded and analyzed using a content analysis approach. Three themes emerged from the content analysis: who vapes, why people vape, and the vape shop environment. Retailers profiled customers as friendly, health conscious, and interested in tobacco cessation or cessation maintenance. Retailers believed e-cigarettes were used recreationally or as products that help curb other addictive behaviors. While most retailers reported positive experiences with vaping, some reported potentially negative experiences including failed cessation attempts, dual use of e-cigarettes and combustible cigarettes, and increased nicotine dependence. Retailers reported that they regularly answer questions about vaping and believe their shops function as social lounges that are tied to other recreational activities. Retailers attach certain characteristics to their clientele, perceive certain health benefits associated with vaping, and seek to establish their shops as places that provide guidance on vape products as well as shops with a recreational aesthetic. As vape shops grow in popularity, additional research on, and regulation of, these retailers will be necessary. Education campaigns are needed to inform retailers of the benefits and consequences of vaping.

Paul, T; Wong, J

1984-01-01

A number of striking parallels between recent developments in health care marketing and changes in the retailing industry exist. The authors have compared retailing paradigms to the area on health care marketing so strategists in hospitals and other health care institutions can gain insight from these parallels. Many of the same economic, demographic, technological and lifestyle forces may be at work in both the health care and retail markets. While the services or products offered in health care are radically different from those of conventional retail markets, the manner in which the products and services are positioned, priced or distributed is surprisingly similar.

Retail competition

International Nuclear Information System (INIS)

1998-01-01

Retail competition as the cornerstone of a competitive electricity marketplace was the subject of the seventh in the series of policy discussion papers developed at the Market Design Conference. Concern was expressed that because of the complexities involved in market design and technical implementation, the retail competition may lag behind other elements of the implementation of the new market design. A variety of key issues were debated, including the role of physical versus financial contracts, the form of retail competition and financial settlement systems in the short term, the requirement to separate 'competitive' (metering, billing, maintenance, consumer education) from non-competitive' (the transmission wires) services and the role of municipal electric utilities. It was agreed that the IMO should play an important role in defining and enforcing the separation of services, and that as a general rule, the development of policy in this area should be guided by the principle of maximizing the potential for competition

2010-01-01

Influence of gamma irradiation and storage on the microbial load, chemical and sensory quality of chicken kabab was investigated. Chicken kabab was treated with 0, 2, 4 or 6 kGy doses of gamma irradiation. Treated and untreated samples were kept in a refrigerator (1-4 deg. C). Microbiological, chemical and sensory characteristics of chicken kabab were evaluated at 0-5 months of storage. Gamma irradiation decreased the microbial load and increased the shelf-life of chicken kabab. Irradiation did not influence the major constituents of chicken kabab (moisture, protein and fats). No significant differences (p>0.05) were observed for total acidity between non-irradiated (control) and irradiated chicken kabab. Thiobarbitric acid (TBA) values (expressed as mg malonaldehyde (MDA)/kg chicken kabab) and volatile basic nitrogen (VBN) in chicken kabab were not affected by the irradiation. Sensory evaluation showed no significant differences between irradiated and non-irradiated samples.

Salmonella spp. are widespread foodborne pathogens that contaminate egg and poultry meats. Attachment, colonization, as well as biofilm formation capacity of Salmonella spp. on food and contact surfaces of food may cause continuous contamination. Biofilm may play a crucial role in the survival of salmonellae under unfavorable environmental conditions, such as in animal slaughterhouses and processing plants. This could serve as a reservoir compromising food safety and human health. Addition of antimicrobial preservatives extends shelf lives of food products, but even when products are supplemented with adequate amounts of preservatives, it is not always possible to inhibit the microorganisms in a biofilm community. In this study, our aims were i) to determine the minimum inhibitory concentrations (MIC) and minimum biofilm inhibitory concentrations (MBIC) of selected preservatives against planktonic and biofilm forms of Salmonella spp. isolated from chicken samples and Salmonella Typhimurium SL1344 standard strain, ii) to show the differences in the susceptibility patterns of same strains versus the planktonic and biofilm forms to the same preservative agent, and iii) to determine and compare antimicrobial and antibiofilm effects of selected food preservatives against Salmonella spp. For this purpose, Salmonella Typhimurium SL1344 standard strain and 4 Salmonella spp. strains isolated from chicken samples were used. Investigation of antimicrobial and antibiofilm effects of selected food preservatives against Salmonella spp. was done according to Clinical and Laboratory Standards Institute M100-S18 guidelines and BioTimer assay, respectively. As preservative agents, pure ciprofloxacin, sodium nitrite, potassium sorbate, sodium benzoate, methyl paraben, and propyl paraben were selected. As a result, it was determined that MBIC values are greater than the MIC values of the preservatives. This result verified the resistance seen in a biofilm community to food

Martin Machek

2012-12-01

Full Text Available This article is analyzing the trends and development in the retailing sector in Central Europe, namely in the Czech Republic, Hungary, Poland and Slovakia. These markets serve about 63 million inhabitants. The retail industry in Central Europe has changed dramatically in the last two decades, and has become a model for successful transformation of emerging markets. The retail market is highly concentrated and dominated by Western European retail chains. International retail chains are using all formats of modern distribution. This article is focusing on the development of hypermarkets, supermarkets and discount stores. Due to the international retail chains, Central European countries benefit from a dense network of modern shopping places; the intense competition of highly productive retailers contributes to the lower level of inflation rate because of the so-called Wal-Mart Effect. The constant pressure on prices influences the marketing strategies of both retailers and suppliers.

The poultry industry has used organoarsenicals, such as 3-nitro-4-hydroxyphenylarsonic acid (Roxarsone, ROX), to prevent disease and to promote growth. Although previous studies have analyzed arsenic species in chicken litter after composting or after application to agricultural lands, it is not clear what arsenic species were excreted by chickens before biotransformation of arsenic species during composting. We describe here the identification and quantitation of arsenic species in chicken litter repeatedly collected on days 14, 24, 28, 30, and 35 of a Roxarsone-feeding study involving 1600 chickens of two strains. High performance liquid chromatography separation with simultaneous detection by both inductively coupled plasma mass spectrometry and electrospray ionization tandem mass spectrometry provided complementary information necessary for the identification and quantitation of arsenic species. A new metabolite, N-acetyl-4-hydroxy-m-arsanilic acid (N-AHAA), was identified, and it accounted for 3-12% of total arsenic. Speciation analyses of litter samples collected from ROX-fed chickens on days 14, 24, 28, 30, and 35 showed the presence of N-AHAA, 3-amino-4-hydroxyphenylarsonic acid (3-AHPAA), inorganic arsenite (As(III)), arsenate (As(V)), monomethylarsonic acid (MMA(V)), dimethylarsinic acid (DMA(V)), and ROX. 3-AHPAA accounted for 3-19% of the total arsenic. Inorganic arsenicals (the sum of As(III) and As(V)) comprised 2-6% (mean 3.5%) of total arsenic. Our results on the detection of inorganic arsenicals, methylarsenicals, 3-AHPAA, and N-AHAA in the chicken litter support recent findings that ROX is actually metabolized by the chicken or its gut microbiome. The presence of the toxic metabolites in chicken litter is environmentally relevant as chicken litter is commonly used as fertilizer.

Quality criteria of irradiated breaded chicken breast fillets were studied. Fresh boneless and skinless breaded chicken breast meats samples were divided into four separate batches and packed in plastic bags and sealed by an impulse sealer. Samples in plastic bags were exposed to different doses of gamma irradiation (2.5, 5 and 7 kGy) at ambient temperature. Just after irradiation, the samples were stored at 4 ±1 0 C. All samples were evaluated for microbiological, chemical and sensorial properties after irradiation and throughout the storage periods. During storage, the total bacterial count was significantly increased (P<0.05) in all samples with higher rates of increase in non-irradiated samples. In all irradiated samples, Staphylococcus aureus did not detected up to 6 days then detected after 22 days in samples treated with 2.5 kGy as well as 31 days in samples treated with 5 kGy. On the other hand, Staphylococcus aureus was detected after 45 days in samples treated with 7 kGy. Salmonella sp., Listeria monocytogenes and Campylobacter jejuni could not detected in untreated and treated samples. The protein content showed significant decrease immediately after irradiation and during the refrigerated storage. The TVN values for non-irradiated samples were significantly higher (P<0.05) than irradiated samples. The present data showed significant decrease (P<0.05) in protein solubility percentages of irradiated samples at day 0 and 6 of refrigerated storage. The observed decrease was related to the increase of radiation dose. At the end of storage period (62 days), 2.5 kGy samples were significantly higher in TBA values than other irradiated samples. On the other hand, irradiation was significantly reduced (P<0.05) the amount of major mono unsaturated and poly unsaturated fatty acids. Sensory attributes of breaded chicken breast fillets did not affected by irradiation. It could be concluded that irradiation dose of 5 kGy can be used in chicken samples stored in

Avian coccidiosis is a huge problem worldwide. Heavily infected animals that show severe clinical signs and coccidiostat resistance are causing important economic losses. The present study aimed to update the recent cases of coccidiosis in Central Java, Indonesia, and to show the importance of the disease in the region. A total of 699 samples were obtained from different chicken breed. Different Eimeria species were detected in 175 individuals (25.04%). Three different groups of chicken breed were considered: local chicken (autochthonous chickens of Sentul and Jawa), commercial broiler, and layer. Broiler chickens showed the highest prevalence of infection (34%), followed by layer (26.26%) and local chickens (10.45%). Mild to severe clinical signs of avian coccidiosis were observed in 42% of the infected animals, while 58% of the infected animals showed no clinical signs other than low feed conversion rates. Seven different Eimeria species were identified: E. tenella was the most prevalent (43.3%), followed by E. maxima (26.3%), E. necatrix (15.7%), E. acervulina (8%), E. praecox (3.1%), E. mitis (2.2%), and E. brunetti (1.3%). Coinfections with several Eimeria species were diagnosed. With this study we found massive usage of coccidiostat in the region even though its usage cannot guarantee coccidiosis-free chicken production.

Comparisons of Sampling Procedures and Time of Sampling for the Detection of Salmonella in Danish Infected Chicken Flocks Raised in Floor Systems

Directory of Open Access Journals (Sweden)

Madsen M

2002-03-01

Full Text Available Bacteriological follow-up samples were taken from 41 chicken (Gallus gallus flocks in floor systems, where Salmonella enterica (Salmonella had been detected either directly in bacteriological samples or indirectly by serological samples. Three types of follow-up samples were compared to each other within each flock: 1 5 pairs of socks, analysed as 5 samples, 2 2 pairs of socks, analysed as one sample, and 3 60 faecal samples, analysed as one pooled sample. Agreement between sampling methods was evaluated by the following statistical tests: 'Kappa', 'The adjusted rand', McNemar's test for marginal symmetry, Proportion of agreement P0, P+, P-, and Odds Ratio. The highest agreement was found between the 2 types of sock sampling, while the lowest agreement was found by comparing 60 faecal samples with 5 pairs of socks. Two pairs of socks analysed as one pool appeared to be just as effective in detecting S. enterica as the 60 faecal samples. In broiler flocks, 5 pairs of socks were used both in the routine samples taken at about 3 weeks of age for the establishment of infection of the flock, and as one of the follow-up samples taken shortly before slaughter age, which means that the only notable differences between the 2 sampling rounds were the age of the broilers and of their litter. S. enterica was detected more frequently in samples from broilers about 3 weeks old, than in similar samples taken from broilers a few days prior to slaughter at ca. 33–40 days of age.

Thermal inactivation of six Salmonella spp. and Listeria innocua was evaluated in ground chicken breast and liquid medium. Survival of Salmonella and Listeria was affected by the medium composition. Under the same thermal process condition, significantly more Salmonella and Listeria survived in chicken breast meat than in 0.1% peptone-agar solution. The thermal lethality of six tested Salmonella spp. was additive in chicken meat. Survival of Listeria in chicken meat during thermal processing was not affected by the presence of the six Salmonella spp. Sample size and shape affected the inactivation of Salmonella and Listeria in chicken meat during thermal processing.

1986-12-01

The possible use of gamma irradiation at doses of 1.6 to 4.0 kGy to improve bacteriological quality of frozen chicken was investigated. The effects of gamma irradiation on salmonella viability in frozen chicken and on sensory quality of frozen chicken were also evaluated. D 10 -values for different isolated strains of salmonella in frozen chicken varied from 0.41 to 0.57 kGy. A dose of 4 kGy is required for a seven log cycle reduction of salmonella contamination in frozen chicken. Approximately 21 per cent of frozen chicken examined were contaminated with salmonella. Salmonella typhimurium, salmonella virchow, and salmonella java were predominant. Irradiation of frozen chicken at a minimum dose of 3.2 kGy eliminated salmonella, coliform, Escherichia coli, and Staphylococcus aureus and, in addition, reduced baterial load by 2 log cycles. Faecal streptococci was still present in a 3.2 kGy samples but in a very small percentage and the count was not over 100 colonies per g. Discoloring of chicken meat was noted after a 2 kGy treatment. The sensory quality of frozen chicken irradiated at 3 and 4 kGy tended to decrease during frozen storage but was within the acceptable range on a nine point hedonic scale even after eight months of frozen storage. Dosage at 3.2 kGy appeared to be sufficient for improving bacteriological quality of frozen chicken

2014-01-01

Shigellosis in chickens was first reported in 2004. This study aimed to determine the pathogenicity of Shigella in chickens and the possibility of cross-infection between humans and chickens. The pathogenicity of Shigella in chickens was examined via infection of three-day-old SPF chickens with Shigella strain ZD02 isolated from a human patient. The virulence and invasiveness were examined by infection of the chicken intestines and primary chicken intestinal epithelial cells. The results showed Shigella can cause death via intraperitoneal injection in SPF chickens, but only induce depression via crop injection. Immunohistochemistry and transmission electron microscopy revealed the Shigella can invade the intestinal epithelia. Immunohistochemistry of the primary chicken intestinal epithelial cells infected with Shigella showed the bacteria were internalized into the epithelial cells. Electron microscopy also confirmed that Shigella invaded primary chicken intestinal epithelia and was encapsulated by phagosome-like membranes. Our data demonstrate that Shigella can invade primary chicken intestinal epithelial cells in vitro and chicken intestinal mucosa in vivo, resulting in pathogenicity and even death. The findings suggest Shigella isolated from human or chicken share similar pathogenicity as well as the possibility of human-poultry cross-infection, which is of public health significance.

2014-06-01

Three experiments were conducted to evaluate the effects of postmortem deboning time on cook yield of boneless skinless chicken thighs. In experiment 1, chicken thigh meat was deboned at 0.75 (hot-bone), 2, and 24 h postmortem (PM) and trimmed to obtain mainly iliotibialis muscle. Samples were cooked directly from a frozen state. Cook yield of the muscle was significantly influenced by PM deboning time. Hot-boned thighs exhibited a 7% greater cook yield than the samples deboned at 24 h. In experiment 2, boneless skinless chicken thighs were deboned at 0.3, 2, and 24 h PM and cooked directly from a fresh, never-frozen state at 24 h PM. Cook yield of the hot-boned thighs was significantly higher than those of the 2 and 24 h deboned samples, which did not differ from each other. In experiment 3, whole legs (thigh + drumstick) were cut from the carcass backbone at 0.3 (hot-cut), 2, and 24 h PM. Thighs were separated from the legs (drumsticks) at either the same time the whole legs were removed from the carcasses or at 24 h PM. Intact thighs (bone in) were cooked fresh at 24 h PM. Color of fresh thigh muscles, cook yield, and Warner-Bratzler shear force of cooked samples were measured. Cook yield of the thighs cut from the backbone before chilling was significantly higher than those cut from the carcasses at 2 and 24 h PM, which did not differ from each other. The PM time at which intact thighs were separated from the leg (drumstick) did not influence cook yield. These results demonstrate that postmortem deboning time can significantly affect cook yield of boneless skinless chicken thigh products. Deboning chicken thighs after chilling reduces the cook yield. Differences in the cook yield of thighs may also result from the removal of whole chicken legs from the carcass backbone. Poultry Science Association Inc.

Full Text Available In this study, thermal inactivation of Salmonella Enteritidis inoculated to the cake dough and a whole raw chicken was investigated. The cake dough was inoculated with 6.15 log-cfu/g S. Enteritidis then, thermal treatment was applied at 160°C top-bottom fan cooking mode. The initial count of S. Enteritidis showed reductions 1.49 log-cfu/g, 2.06 log-cfu/g and 4.29 log-cfu/g in the samples from the cold point location from the geometric center of the cake at 5, 7 and 10 minutes of thermal treatment, respectively. Although S. Enteritidis is not detected at the end of 15 minutes of heat treatment, the center of the cake temperature has reached 85.69°C and the cake sample is uncooked and its sensory properties are not acceptable. The cake that is safe and favorable with the sensory properties to the consumers was obtained by heat treatment for 30 minutes. After the cold point of a whole raw chicken was inoculated with 7.29 log-cfu/g S. Enteritidis, thermal treatment was applied at 220°C top-bottom fan cooking mode. The temperature at the cold point of 35 and 45 minutes heat-treated chickens reached 59.33 and 74.08°C, respectively, and 1.93 log-cfu/g and 5.33 log-cfu /g S. Enteritidis reduction caused in the samples respectively. S. Enteritidis cells were not detected in the whole chicken heat treated at 220°C for 60 minutes. The cakes, heat treated at 160°C top-bottom fan cooking mode for 30 minutes, were stored at two different storage temperatures as 4°C and 25°C for 72 hours. The whole chicken, heat treated at 220°C top-bottom fan cooking mode for 60 minutes, was stored at 4°C for 72 hours. S. Enteritidis cells were not detected in the cake and the whole chicken samples after the storage period.

Due to the consumption of chicken and chicken products in Turkey at high ratio, trace metal content of chicken and chicken products from Turkey were determined by atomic absorption spectrometry after microwave digestion. The accuracy of the method was confirmed by analysis of standard reference material (NIST SRM 1577b Bovine liver). Trace element content in various parts of chicken samples and chicken products were to be in the range of 0.10-114 μg/g for copper, 0.25-6.09 μg/kg for cadmium, 0.01-0.40 μg/g for lead, 0.10-0.91 μg/g for selenium, 0.05-3.91 μg/g for manganese, 0.06-0.10 μg/g for arsenic, 0.01-0.72 μg/g for chromium, 0.01-2.08 μg/g for nickel, 0.01-0.02 μg/g for cobalt, 0.10-1.90 μg/g for aluminium, 1.21-24.3 μg/g for zinc, 2.91-155 μg/g for iron. The levels of lead in some analyzed chicken products were higher than the recommended legal limits for human consumption

Quantification of Campylobacter spp. in chicken rinse samples by using flotation prior to real-time PCR

DEFF Research Database (Denmark)

Wolffs, Petra; Norling, Börje; Hoorfar, Jeffrey

2005-01-01

Real-time PCR is fast, sensitive, specific, and can deliver quantitative data; however, two disadvantages are that this technology is sensitive to inhibition by food and that it does not distinguish between DNA originating from viable, viable nonculturable (VNC), and dead cells. For this reason......, real-time PCR has been combined with a novel discontinuous buoyant density gradient method, called flotation, in order to allow detection of only viable and VNC cells of thermotolerant campylobacters in chicken rinse samples. Studying the buoyant densities of different Campylobacter spp. showed...... enrichment and amounts as low as 2.6 X 10(3) CFU/ml could be quantified. Furthermore, subjecting viable cells and dead cells to flotation showed that viable cells were recovered after flotation treatment but that dead cells and/or their DNA was not detected. Also, when samples containing VNC cells mixed...

Effect of irradiation on lipid oxidation in eviscerated chicken carcasses during storage

International Nuclear Information System (INIS)

Hassan, I.M.; Hussein, M.F.; Mahmoud, A.A.; Hegazy, R.A.

1988-01-01

Oxidative changes induced in pectoralis major muscle of chicken after irradiation treatments with 0,6,10 and 20 KGy in both non frozen or frozen conditions during subsequent storage were investigated. Ultraviolet (UV) absorption, peroxides and thiobarbituric reactive substances increased in chicken lipids with increasing irradiation doses. These oxidative changes are greater in irradiated refrigerated (4 ± 1°C) than in irradiated frozen (-20°C) chicken lipids during storage. It was found the peroxides and TBA reactive substances do not accumulate as a stable end products of fat oxidation but reach a maximum during storage followed by gradual declining. The UV absorption provides an objective measure of chicken lipids autoxidation suitable for following the progress of autoxidation of irradiated chicken during subsequent non frozen (4 ± 1°C) or frozen (-20°C) storage. The extent of Maillard-like browning was followed in both unirradiated and irradiated samples during storage. All tested objective parameters correlated well with sensory assessment of odour particularly when irradiation dose was increased as well as in frozen samples

The antibody to chicken infectious anemia virus (CIAV) was positive in a specific pathogen-free (SPF) chicken population by ELISA test in our previous inspection, indicating a possible infection with CIAV. In this study, blood samples collected from the SPF chickens were used to isolate CIAV by inoculating into MSB1 cells and PCR amplification. A CIAV strain (SD1403) was isolated and successfully identified. Three overlapping genomic fragments were obtained by PCR amplification and sequencing. The full genome sequence of the SD1403 strain was obtained by aligning the sequences. The genome of the SD1403 strain was 2293 bp with a nucleotide identity of 94.8% to 98.5% when compared with 30 referred CIAV strains. The viral proteins VP2 and VP3 were highly conserved, but VP1 was not relatively conserved. Both amino acids 139 and 144 of VP1 were glutamine, which was in accord with the low pathogenic characteristics. In this study, we first reported that CIAV exists in Chinese SPF chicken populations and may be an important reason why attenuated vaccine can be contaminated with CIAV.

The emerging marijuana retail environment: Key lessons learned from tobacco and alcohol retail research.

Science.gov (United States)

Berg, Carla J; Henriksen, Lisa; Cavazos-Rehg, Patricia A; Haardoerfer, Regine; Freisthler, Bridget

2018-06-01

The emerging retail market for recreational marijuana use warrants research and surveillance as such markets are established in more US states. This research can be informed by the existing literature regarding tobacco and alcohol, which highlights the impact of spatial access to tobacco and alcohol retailers and exposure to tobacco and alcohol marketing on smoking and drinking among youth and young adults. Prior research indicates that tobacco and alcohol retailers, as well as medical marijuana dispensaries, are disproportionately located in neighborhoods characterized by socioeconomic disadvantage and by higher proportions of racial/ethnic minorities and young adults. Moreover, retail marketing or point-of-sale practices may differentially target subpopulations and differ by neighborhood demography and local policy. This literature and the methods employed for studying the tobacco and alcohol market could inform research on the retail environment for marijuana, as current gaps exist. In particular, much of the existing literature involves cross-sectional research designs; longitudinal studies are needed. Moreover, standardized measures are needed for systematic monitoring of industry marketing practices and to conduct research examining neighborhood differences in exposure to retail marketing for marijuana and its contribution to use modality and frequency, alone and in combination with nicotine and alcohol. The use of standardized measures for tobacco and alcohol marketing have been critical to develop an evidence base from cross-sectional and longitudinal studies that document the impact of retail marketing on substance use by adolescents and adults. Similar research is needed to establish an evidence base to inform federal, state, and local regulations of marijuana. Copyright © 2018 Elsevier Ltd. All rights reserved.

Since their introduction in 2007, electronic cigarette ('e-cigarette') awareness and use has grown rapidly. Little is known about variation in e-cigarette availability across areas with different levels of tobacco taxes and smoke-free air policies. This paper looks at US retail availability of e-cigarettes and factors at the store, neighbourhood and policy levels associated with it. In-person store audit data collected in 2012 came from two national samples of tobacco retailers in the contiguous US. Study 1 collected data from a nationally representative sample of tobacco retailers (n=2165). Study 2 collected data from tobacco retailers located in school enrolment zones for nationally representative samples of 8th, 10th and 12th grade public school students (n=2526). In 2012, e-cigarette retail availability was 34% in study 1 and 31% in study 2. Tobacco, pharmacy and gas/convenience stores were more likely to sell e-cigarettes than beer/wine/liquor stores. Retail availability of e-cigarettes was more likely in neighbourhoods with higher median household income (study 1), and lower percent of African-American (studies 1 and 2) and Hispanic residents (study 2). Price of traditional cigarettes was inversely related to e-cigarette availability. Stores in states with an American Lung Association Smoke-Free Air grade of F (study 1) or D (study 2) compared with A had increased likelihood of having e-cigarettes. Currently, e-cigarette availability appears more likely in areas with weak tax and smoke-free air policies. Given the substantial availability of e-cigarettes at tobacco retailers nationwide, states and localities should monitor the sales and marketing of e-cigarettes at point of sale (POS).

Marination using various ingredients has been widely used to improve microbial safety and quality of chicken products at retail markets. The objective of this study was to investigate the effects of commercial marinade seasoning and cultured sugar/vinegar blend on Campylobacter jejuni and Salmonella Typhimurium populations during refrigerated storage. In addition, their effects on the texture of precooked chicken breasts during frozen and refrigerated storage was investigated. Chicken breasts inoculated with 4.5 to 5.0 log cfu/g of C. jejuni and Salmonella Typhimurium were treated with 3% cultured sugar/vinegar blend with and without 0.6% polish rub seasoning containing 32% herb content. Breasts were then vacuum-packaged and stored at 4 and 10°C. Survival and growth curves were fitted to the Baranyi equation to determine survival and growth kinetics of C. jejuni and Salmonella Typhimurium. In addition, the vacuum-packaged precooked chicken breasts with different marination treatments were subjected to 3 freeze-thaw cycles and shear force was measured. At 4°C, the populations of C. jejuni and Salmonella Typhimurium decreased, regardless of treatment group during storage. The greatest survival for C. jejuni was observed in untreated chicken breasts. At 10°C, the growth of Salmonella Typhimurium was completely prevented in precooked chicken breasts treated with 3% cultured sugar/vinegar blend, regardless of the presence of 0.6% seasoning. The 3% cultured sugar/vinegar blend also improved the tenderness of frozen chicken breasts and refrigerated, ready-to-eat chicken breast. Therefore, a natural blend of cultured sugar and vinegar can be used as antimicrobial and texture-modifying agents for poultry meat and poultry products.

Coccidiosis, caused by species of the apicomplexan parasite Eimeria, is a major disease of chickens. Eimeria species are present world-wide, and are ubiquitous under intensive farming methods. However, prevalence of Eimeria species is not uniform across production systems. In developing countries such as Ethiopia, a high proportion of chicken production occurs on rural smallholdings (i.e. 'village chicken production') where infectious diseases constrain productivity and surveillance is low. Coccidiosis is reported to be prevalent in these areas. However, a reliance on oocyst morphology to determine the infecting species may impede accurate diagnosis. Here, we used cross-sectional and longitudinal studies to investigate the prevalence of Eimeria oocyst shedding at two rural sites in the Ethiopian highlands. Faecal samples were collected from 767 randomly selected chickens in May or October 2011. In addition, 110 chickens were sampled in both May and October. Eimeria oocysts were detected microscopically in 427 (56%, 95% confidence interval (95% CI) 52-59%) of the 767 faecal samples tested. Moderate clustering of positive birds was detected within households, perhaps suggesting common risk factors or exposure pathways. Seven species of Eimeria were detected by real time PCR in a subset of samples further analysed, with the prevalence of some species varying by region. Co-infections were common; 64% (23/36, 95% CI 46-79%) of positive samples contained more than one Eimeria spp. Despite frequent infection and co-infection overt clinical disease was not reported. Eimeria oocysts were detected significantly more frequently in October (248/384, 65%, 95% CI 60-69%), following the main rainy season, compared to May (179/383, 47%, 95% CI 42-52%, p Eimeria oocyst positivity in May did not significantly affect the likelihood of detecting Eimeria oocyst five months later perhaps suggesting infection with different species or immunologically distinct strains.

Comparison of antimicrobial resistant genes in chicken gut microbiome grown on organic and conventional diet

Directory of Open Access Journals (Sweden)

Narasimha V. Hegde

2016-12-01

Full Text Available Antibiotics are widely used in chicken production for therapeutic purposes, disease prevention and growth promotion, and this may select for drug resistant microorganisms known to spread to humans through consumption of contaminated food. Raising chickens on an organic feed regimen, without the use of antibiotics, is increasingly popular with the consumers. In order to determine the effects of diet regimen on antibiotic resistant genes in the gut microbiome, we analyzed the phylotypes and identified the antimicrobial resistant genes in chicken, grown under conventional and organic dietary regimens. Phylotypes were analyzed from DNA extracted from fecal samples from chickens grown under these dietary conditions. While gut microbiota of chicken raised in both conventional and organic diet exhibited the presence of DNA from members of Proteobacteria and Bacteroidetes, organic diet favored the growth of members of Fusobacteria. Antimicrobial resistance genes were identified from metagenomic libraries following cloning and sequencing of DNA fragments from fecal samples and selecting for the resistant clones (n=340 on media containing different concentrations of eight antibiotics. The antimicrobial resistant genes exhibited diversity in their host distribution among the microbial population and expressed more in samples from chicken grown on a conventional diet at higher concentrations of certain antimicrobials than samples from chicken grown on organic diet. Further studies will elucidate if this phenomena is widespread and whether the antimicrobial resistance is indeed modulated by diet. This may potentially assist in defining strategies for intervention to reduce the prevalence and dissemination of antibiotic resistance genes in the production environment.

This study explored the thermal characteristics (D- and z-values) of Salmonella Typhimurium in raw chicken shawirma. Marinated and non-marinated chicken breasts with skin were inoculated with S. Typhimurium 112 or S. Typhimurium 144. Inoculated samples were ground, packed in sterile bags and submerged in a water bath at 54, 56, 58 and 60°C for 2.5 to 72min. The mean D-values of S. Typhimurium strains in inoculated, non-marinated, ground raw chicken breast, as well as those of S. Typhimurium 15h after exposure to the marinade (inoculated before marinating, IBM) or after brief exposure (30min) to the marinade (inoculated after marinating, IAM) ranged from 9.15 to 12.44, 2.89 to 3.92, 1.06 to 1.30 and 0.32 to 0.52min at 54, 56, 58 and 60°C, respectively. Generally, no significant differences (P>0.05) were found among the D-values of S. Typhimurium in all chicken samples. However, the D-values of S. Typhimurium in raw ground chicken shawirma IBM were the lowest. The z-values of S. Typhimurium in all products ranged from 3.78 to 4.58°C. It was concluded that thorough cooking of the outside of the shawirma meat cylinder or cone before removal of slices at foodservice counters can enhance the safety of the product.

Cooking loss, tenderness, and sensory evaluation of chicken meat roasted after wrapping with edible films.

Science.gov (United States)

Küçüközet, Ahmet Oktay; Uslu, Mustafa Kemal

2018-01-01

In this study, edible films were produced from sodium caseinate and a sodium caseinate-starch mixture and with or without oleoresins (cumin and oregano oleoresin mixture). Chicken meat was wrapped in the respective films, stored at 4 ℃ for four days, and roasted at 200 ℃ for 30 min. The cooking loss, color changes, instrumental tenderness (shear force and energy) were measured. In addition, sensory evaluation was performed. All films effectively reduced cooking loss from chicken meat. The sodium caseinate-starch-based films were the most successful in preventing cooking loss. The average shear force and shear energy values of the wrapped samples were about 40% and 30% less than those of control samples, respectively. In sensory evaluation, chicken meat roasted after wrapping with the films was considered more tender and delicious than the control. Particularly, chicken meat wrapped with the films containing oleoresin mixture was assessed as the most delicious among the samples. It was shown that the cooking quality of the chicken meat could be significantly improved by pre-wrapping the meat with edible films.

This study evaluated the effectiveness of 11 chemical compounds to reduce Campylobacter jejuni on chicken skin and meat samples dipped in chemical solutions. Treatment of skin samples for 1 min using tartaric acid (2%) and caprylic acid sodium salt (5%) caused reductions of C. jejuni NCTC11168...... effective, indicating that some cells may recover after a 1-min treatment with these chemicals. An increase in treatment time to 15 min resulted in higher effectiveness of trisodium phosphate and formic acid. Interestingly, when reduction of the C. jejuni population was compared on chicken skin and meat...

Objectives Electronic nicotine delivery systems (ENDS) have recently emerged as a component of the tobacco retail environment. The aims of this study were to describe the availability, types of ENDS and placement of ENDS relative to traditional tobacco products at franchised licensed tobacco retailers and non-franchised licensed tobacco retailers. Design Observational study. Setting Franchised and non-franchised tobacco retailers in Cleveland County, Oklahoma, USA. Primary and secondary outcome measures The number of stores selling ENDS, the variability in brands of ENDS sold, the location of the ENDS within the retailers, the quantity of ENDS sold compared with traditional tobacco products, and the presence of outdoor signage. Results Data from 57 randomly sampled tobacco retailers were used to describe the presence of ENDS at independent non-franchised and franchised tobacco retailers. The overwhelming majority (90%) of licensed tobacco retailers sold ENDS, and differences were observed between franchised and non-franchised stores. 45 of the 51 retailers (88%) selling ENDS had them placed at the point of sale. 2 of the 21 franchised retailers (9.5%) had ENDS placed at ≤3½ feet above floor level compared to none of the 30 non-franchised retailers (0%). Conclusions This small study is the first to characterise ENDS within the tobacco retail environment in a county in Oklahoma, USA. The results from this study demonstrate the complexity of the tobacco retail landscape and generate questions for future studies regarding the incorporation and placement of ENDS in tobacco retail environments.

Employing approximately 1.5 million employees and comprised of 80,000 employers, the retail and wholesale sector accounted for 16.1% of South Africa's gross domestic product in 1996. HIV/AIDS threatens the retail sector, but it is unclear whether the pandemic threatens equally every sub-sector of the industry. The 4 main sub-sectors are fast-moving consumer goods; clothing, footwear, and textiles; vehicles; and furniture and major appliances. The nature of retail infrastructure and competitive and economic trends are described. Over the next decade, AIDS may reduce the size of consumer markets through increased mortality, and will certainly slow growth in spending. The pandemic may also divert spending away from retail merchandise to health care, and threaten businesses which extend credit and offer death benefits and funeral policies to clients. AIDS morbidity and mortality could also disrupt supply chains, especially for retailers who buy their products locally. The vulnerability of retail activities is discussed, with reference to the Living Standards Measure (LSM) developed by the South African Advertising Research Foundation.

Chicken were subjected to gamma irradiation doses of 2.5, 5.0, 7.5 and 10.0 KGy and post-irradiation storage of 21 days at 4±2º. The effects on fat and protein of chicken were studied. Rate of formation of total volatile basic-nitrogen was less in irradiated samples particularly in samples treated with 5.0KGy during the entire storage. Fatty acid profiles of chicken lipids were not significantly (P≤ 0.05) affected by irradiation especially at doses of 5.0 KGy. However, irradiation caused a large increase in thiobarbituric acid (TBA) values which continued gradually during storage. Changes in amino acids were minimal. Irradiated and unirradiated samples showed the appearance of protein subunits with molecular weights in the range of 10.0 to 88.0 and 10.0 to 67.0 KD, respectively. No changes were observed in the sarcoplasmic protein but the intensity of bands in all irradiated samples decreased after 21 days of storage

Some life-threatening, foodborne, and zoonotic infections are transmitted through poultry birds. Inappropriate and indiscriminate use of antimicrobials in the livestock industry has led to an increased prevalence of multidrug-resistant bacteria with epidemic potential. Here, we present a functional molecular epidemiological analysis entailing the phenotypic and whole-genome sequence-based characterization of 11 H. pullorum isolates from broiler and free-range chickens sampled from retail wet markets in Hyderabad City, India. Antimicrobial susceptibility tests revealed all of the isolates to be resistant to multiple antibiotic classes such as fluoroquinolones, cephalosporins, sulfonamides, and macrolides. The isolates were also found to be extended-spectrum β-lactamase producers and were even resistant to clavulanic acid. Whole-genome sequencing and comparative genomic analysis of these isolates revealed the presence of five or six well-characterized antimicrobial resistance genes, including those encoding a resistance-nodulation-division efflux pump(s). Phylogenetic analysis combined with pan-genome analysis revealed a remarkable degree of genetic diversity among the isolates from free-range chickens; in contrast, a high degree of genetic similarity was observed among broiler chicken isolates. Comparative genomic analysis of all publicly available H. pullorum genomes, including our isolates (n = 16), together with the genomes of 17 other Helicobacter species, revealed a high number (8,560) of H. pullorum-specific protein-encoding genes, with an average of 535 such genes per isolate. In silico virulence screening identified 182 important virulence genes and also revealed high strain-specific gene content in isolates from free-range chickens (average, 34) compared to broiler chicken isolates. A significant prevalence of prophages (ranging from 1 to 9) and a significant presence of genomic islands (0 to 4) were observed in free-range and broiler chicken isolates

2012-02-01

The objectives of this study were to use a meat flavor lexicon to identify and quantify flavor differences among different types of meats such as beef, chicken, lamb, pork, and turkey, and to identify and quantify specific flavor attributes associated with "beef flavor" notes. A trained descriptive panel with 11 participants used a previously developed meat lexicon composed of 18 terms to evaluate the flavor of beef, chicken, pork, turkey, and lamb samples. Results show that beef and lamb samples can be described by flavor attributes such as barny, bitter, gamey, grassy, livery, metallic, and roast beef. Inversely related to these samples were pork and turkey and those attributes that were closely related to them, namely brothy, fatty, salty, sweet, and umami. Chicken was not strongly related to the other types of meats or the attributes used. The descriptive panel also evaluated samples of ground beef mixed with chicken to identify and quantify flavor attributes associated with a "beef flavor." Meat patties for this portion consisted of ground beef mixed with ground chicken in varying amounts: 0%, 25%, 50%, 75%, and 100% beef, with the remainder made up of chicken. Beef and beef-rich patties (75% beef) were more closely related to flavor attributes such as astringent, bloody, fatty, gamey, metallic, livery, oxidized, grassy, and roast beef, while chicken was more closely associated with brothy, juicy, sour, sweet, and umami. This research provides information regarding the specific flavor attributes that differentiate chicken and beef products and provides the first set of descriptors that can be associated with "beefy" notes. POTENTIAL APPLICATION: The use of a standardized flavor lexicon will allow meat producers to identify specific flavors present in their products. The impact is to identify and quantify negative and positive flavors in the product with the ultimate goal of optimizing processing or cooking conditions and improve the quality of meat products. �

Fresh produce items can become contaminated with enteric pathogens along the supply chain at the preharvest (e.g., irrigation water, soil, fertilizer) or postharvest (e.g., vendor handling or consumer handling) stages. This study assesses the concentrations of fecal indicator bacteria Escherichia coli , enterococci (ENT), and Bacteriodales on surfaces of carrots, eggplants, red amaranth leaves, and tomatoes obtained from both a wholesale market (recently harvested) and neighborhood retail markets in Dhaka, Bangladesh. We detected E. coli in 100% of carrot and red amaranth rinses, 92% of eggplant rinses, and 46% of tomato rinses. Using a molecular microbial source tracking assay, we found that 32% of produce samples were positive for ruminant fecal contamination. Fecal indicator bacteria were more likely to be detected on produce collected in retail markets compared with that in the wholesale market; retail market produce were 1.25 times more likely to have E. coli detected ( P = 0.03) and 1.24 times more likely to have ENT detected ( P = 0.03) as compared with wholesale market produce. Bacteriodales was detected in higher concentrations in retail market produce samples compared with wholesale market produce samples (0.40 log 10 gene copies per 100 cm 2 higher, P = 0.03). Our results suggest that ruminant and general fecal contamination of produce in markets in Dhaka is common, and suggest that unsanitary conditions in markets are an important source of produce fecal contamination postharvest.

Backyard poultry are regaining popularity in Europe and increased interest in the health and management of non-commercial farms has resulted. Furthermore, commercial poultry farm owners have become concerned about the risk represented by contagious avian diseases that nearby backyard poultry could transmit. Fifty-one voluntary backyard chicken farms were visited between October 2012 and January 2013. Blood samples and individual cloacal swabs were collected from 457 chickens. In 44 farms (86%), one or more of the tested chickens had antibodies against avian encephalomyelitis and chicken infectious anaemia viruses, 24 farms (47%) had chickens seropositive for infectious bronchitis virus, 10 farms (20%) had chickens seropositive for infectious bursal disease virus, six farms (12%) had chickens seropositive for infectious laryngotracheitis virus and two farms (5.4%) had chickens seropositive for avian influenza virus. No farms had chickens seropositive for Newcastle disease virus. Of the 51 farms, five (10%) had chickens positive for coronavirus reverse transcription polymerase chain reaction. A phylogenetic analysis showed that all backyard chicken coronaviruses collected were QX type infectious bronchitis viruses. All chickens tested for avian influenza and Newcastle disease viruses using real time reverse transcription polymerase chain reaction were negative. To our knowledge, there is no evidence to date to suggest that these diseases would have been transmitted between commercial and non-commercial flocks.

The urgency of the task of analyzing the foodstuffs quality is determined by the strategy for the formation of a healthy lifestyle and the rational nutrition of the world population. This applies to products, such as chicken eggs. In particular, it is necessary to control the chicken eggs quality at the farm production prior to incubation in order to eliminate the possible hereditary diseases, as well as high embryonic mortality and a sharp decrease in the quality of the bred young. Up to this day, in the market there are no objective instruments of contactless express quality control as analytical equipment that allow the high-precision quality examination of the chicken eggs, which is determined by the color parameters of the eggshell (color uniformity) and yolk of eggs, and by the presence in the eggshell of various defects (cracks, growths, wrinkles, dirty). All mentioned features are usually evaluated only visually (subjectively) with the help of normalized color standards and ovoscopes. Therefore, this work is devoted to the investigation of the application opportunities of contactless express control method with the help of technical vision to implement the chicken eggs' quality analysis. As a result of the studies, a prototype with the appropriate software was proposed. Experimental studies of this equipment on a representative sample of eggs from chickens of different breeds have been carried out (the total number of analyzed samples exceeds 300 pieces). The correctness of the color analysis was verified by spectrophotometric studies of the surface of the eggshell.

2018-07-01

Retailer mobility, defined as the shifting geographic patterns of retail locations over time, is a significant but understudied factor shaping neighborhood food environments. Our research addresses this gap by analyzing changes in proximity to SNAP authorized chain retailers in the Atlanta urban area using yearly data from 2008 to 2013. We identify six demographically similar geographic clusters of census tracts in our study area based on race and economic variables. We use these clusters in exploratory data analysis to identify how proximity to the twenty largest retail food chains changed during this period. We then use fixed effects models to assess how changing store proximity is associated with race, income, participation in SNAP, and population density. Our results show clear differences in geographic distribution between store categories, but also notable variation within each category. Increasing SNAP enrollment predicted decreased distances to almost all small retailers but increased distances to many large retailers. Our chain-focused analysis underscores the responsiveness of small retailers to changes in neighborhood SNAP participation and the value of tracking chain expansion and contraction in markets across time. Better understanding of retailer mobility and the forces that drive it can be a productive avenue for future research. Copyright © 2018 Elsevier Ltd. All rights reserved.

AN OVERVIEW ON RETAIL REVERSE LOGISTICS

Directory of Open Access Journals (Sweden)

Ioana Olariu

2014-07-01

Full Text Available This article is a theoretical approach on retail reverse logistics. Environmental concern and the current marketing strategy have spurred retailers to implement strategies to facilitate product returns from end customers. Reverse logistics, indicating the process of this return flow, encompasses such activities as the movement of returned products, facilities to accommodate returned items, and overall remedy process for returned items. The retail industry, under great competitive pressure, has used return policies as a competitive weapon. Grocery retailers were the first to begin to focus serious attention on the problem of returns and to develop reverse logistics innovations. Grocery retailers first developed innovations such as reclamation centers. Reclamation centers, in turn, led to the establishment of centralized return centers. Centralizing returns has led to significant benefits for most firms that have implemented them. Over the last several years, retailers have consolidated. Now, more than ever, reverse logistics is seen as being important. This reverse distribution activity can be crucial to the survival of companies, because the permanent goodwill of the company is at stake. Businesses succeed because they respond to both external and internal changes and adjust in an effective manner to remain competitive.

An outbreak of campylobacter enteritis involving 7 of 17 people over a period of 5 days followed a dinner at a restaurant. A chicken casserole dish was implicated with a food-specific attack rate of 58%. Campylobacter jejuni Penner serotype 18/21/29, resistant to metronidazole, was isolated from 3 of 4 symptomatic patients and from three raw fresh chicken samples closely associated with the implicated chicken. Numbers of C. jejuni in the chicken ranged from 5.3 X 10(1) to 7.5 X 10(2) colony forming units per square centimeter of surface area. This is the first outbreak of campylobacter enteritis reported in Australia in which C. jejuni has been isolated from both human and food sources and the isolates serologically confirmed as identical.

Full Text Available Manufacturing companies took advantage of internationalization as early as in the seventies and eighties of the last century, whereas retail companies have used these chances not before the last few years in order to improve access to resources, to increase sales and to extend activities to external markets. Once a retail company has decided to penetrate a foreign market they must be aware of the unfamiliar working of external environment that they cannot control. Even the world’s leading retailers make mistakes when approaching markets they do not understand properly.

Chicken infectious anaemia (CIA) is a disease with a highly economic impact in the poultry industry. The infected chickens are characterized by aplastic anaemia and extreme immunosuppression, followed by the increased susceptibility to secondary infectious pathogens and suboptimal immune responses for vaccination. Commercially available CIA vaccines are routinely used in the breeders in Taiwan to protect their progeny with maternal-derived antibodies. However, CIA cases still occur in the field and little is known about the genetic characteristics of Taiwanese chicken anaemia viruses (CAVs). In this study, CAV DNA was detected in 72 of 137 flocks collected during 2010-2015. Among the PCR-positive samples, the coding regions of 51 CAVs were sequenced. Phylogenetic analysis of the VP1 gene revealed that, although most of Taiwanese CAVs belonged to genotypes II and III, some isolates were clustered into a novel genotype (genotype IV). Moreover, a Taiwanese isolate in this novel genotype IV appeared to be derived from a recombination event between genotypes II and III viruses. Five Taiwanese CAV isolates were highly similar to the vaccine strains, 26P4 or Del-Ros. Taken together, these results indicate that the sequences of CAVs in Taiwan are variable, and inter-genotypic recombination had occurred between viruses of different genotypes. Moreover, vaccine-like strains might induce clinical signs of CIA in chickens. Our findings could be useful for understanding the evolution of CAVs and development of a better control strategy for CIA. © 2018 Blackwell Verlag GmbH.

A new active portfolio risk management for an electricity retailer based on a drawdown risk preference

International Nuclear Information System (INIS)

Charwand, Mansour; Gitizadeh, Mohsen; Siano, Pierluigi

2017-01-01

This paper addresses the deciding under uncertainty of an electricity retailer in order to maximise its total expected rate of return. The developed methodology is based on the modelling of the stochastic evolution of zonal prices that seeks to manage a portfolio of different contracts. Retailer's load and the price at each zone are forecasted using the seasonal autoregressive integrated moving average (SARIMA) model and a clustering technique is used for scenario reduction. Supply sources include the pool, self-production facilities, forward and bilateral contracts. The risk of cost fluctuation due to uncertainties is explicitly modelled using the multi-scenario drawdown methodology. This risk function quantifies in aggregated format the frequency and magnitude of the portfolio drawdowns over planning horizon. In-sample and out-of-sample runs are performed for a portfolio allocation problem. Carried out experimental results on the basis of realistic data, show that imposing risk constraints improve the “real” performance of a portfolio management in out-of-sample runs. - Highlights: • A new drawdown-based method is introduced to retailer deciding under uncertainty. • This tool is used to assess the risk levels regarding retailer midterm strategies. • The methodology is based on the modeling of the stochastic evolution of zonal prices. • The risk function quantifies the frequency and magnitude of the portfolio drawdowns. • In-sample and out-of-sample runs are performed for a portfolio allocation problem.

Microbiological Safety of Chicken Litter or Chicken Litter-Based Organic Fertilizers: A Review

Directory of Open Access Journals (Sweden)

Zhao Chen

2014-01-01

Full Text Available Chicken litter or chicken litter-based organic fertilizers are usually recycled into the soil to improve the structure and fertility of agricultural land. As an important source of nutrients for crop production, chicken litter may also contain a variety of human pathogens that can threaten humans who consume the contaminated food or water. Composting can inactivate pathogens while creating a soil amendment beneficial for application to arable agricultural land. Some foodborne pathogens may have the potential to survive for long periods of time in raw chicken litter or its composted products after land application, and a small population of pathogenic cells may even regrow to high levels when the conditions are favorable for growth. Thermal processing is a good choice for inactivating pathogens in chicken litter or chicken litter-based organic fertilizers prior to land application. However, some populations may become acclimatized to a hostile environment during build-up or composting and develop heat resistance through cross-protection during subsequent high temperature treatment. Therefore, this paper reviews currently available information on the microbiological safety of chicken litter or chicken litter-based organic fertilizers, and discusses about further research on developing novel and effective disinfection techniques, including physical, chemical, and biological treatments, as an alternative to current methods.

“Chickens Are a Lot Smarter than I Originally Thought”: Changes in Student Attitudes to Chickens Following a Chicken Training Class

Susan J. Hazel

2015-08-01

Full Text Available A practical class using clicker training of chickens to apply knowledge of how animals learn and practice skills in animal training was added to an undergraduate course. Since attitudes to animals are related to their perceived intelligence, surveys of student attitudes were completed pre- and post- the practical class, to determine if (1 the practical class changed students’ attitudes to chickens and their ability to experience affective states, and (2 any changes were related to previous contact with chickens, training experience or gender. In the post- versus pre-surveys, students agreed more that chickens are easy to teach tricks to, are intelligent, and have individual personalities and disagreed more that they are difficult to train and are slow learners. Following the class, they were more likely to believe chickens experience boredom, frustration and happiness. Females rated the intelligence and ability to experience affective states in chickens more highly than males, although there were shifts in attitude in both genders. This study demonstrated shifts in attitudes following a practical class teaching clicker training in chickens. Similar practical classes may provide an effective method of teaching animal training skills and promoting more positive attitudes to animals.

Following a large regulatory reform in 2009, which ended the state's pharmacy monopoly, non-pharmacy retailers in Sweden today sell certain over-the-counter (OTC) drugs. The aim of this study was to investigate consumer preferences regarding OTC drug retailers and the reasons for choosing a pharmacy versus non-pharmacy retailer. We conducted a web survey aimed at Swedish adults. Out of a stratified sample of 4058 persons, 2594 agreed to take part (48% women; mean age: 50.3 years). Questions related to OTC drug use, retailer choice and factors affecting the participants' preferences for OTC drug retailers. Logistic regression was conducted to analyse OTC drug use and reasons for retailer choice in relation to sex, age and education. Nine in ten participants reported OTC drug use in the 6 months prior to the study. For their last OTC purchase, 76% had gone to a pharmacy, 20% to a grocery shop and 4% to a convenience store, gas station or online. Geographic proximity, opening hours and product range were reported as the most important factors in retailer choice. Counselling by trained staff was important to 57% of participants. The end of the state's pharmacy monopoly and the increase in number of pharmacies seem to have impacted more on Swedish consumers' purchase behaviours compared with the deregulation of OTC drug sales.

The incidence and severity of disease associated with toxigenic Clostridium difficile have increased in hospitals in North America from the emergence of newer, more virulent strains. Toxigenic C. difficile has been isolated from food animals and retail meat with potential implications of transfer to human beings. The objective of the present study was to determine the prevalence of C. difficile in pork from sausage manufacturing plants and retail meat in Texas. Twenty-three C. difficile isolates were detected from 243 meat samples (9.5%) from 3 sausage-manufacturing plants and 5 retail meat outlets from 2004 to 2009. Twenty-two isolates were positive for toxins A, B, and binary toxin, and were characterized as toxinotype V, PFGE type-NAP7, or "NAP7-variant." Susceptibilities to 11 antimicrobial agents in the current study were similar to those reported previously for toxinotype V isolates, although the results suggested somewhat reduced resistance than reported for other meat, animal, or human clinical toxinotype V isolates.

The retail market : a consumer perspective

International Nuclear Information System (INIS)

Girvan, J.

2002-01-01

A consumer's perspective of the Ontario open retail electricity market was presented. The author, who believes the retail market in Ontario is flawed, presents some key decisions that were made regarding open competition, that may have been done differently or which have helped the market move forward. It was noted that the 1996 report by the Macdonald Committee clearly recommended that retail competition should be phased in only after the wholesale market was in place. That report also cautioned about the risks of proceeding with an open retail market without being properly prepared. The Ontario government rejected the recommendations of the Macdonald Committee and chose to open both wholesale and retail markets at the same time. Another important decision by the Ontario Energy Board was to determine that Standard Supply Service customers would be billed on the basis of a spot price pass-through model. It was noted that the lack of understanding by consumers regarding the new market and the absence of a comprehensive education campaign gave retailers an opportunity to deceive some customers. Allowing retailing prior to the introduction of unbundled bills has also led to the current state of customer confusion. Although the government has now made communication efforts, it is believed that these efforts must be greater in assuring that local distribution companies are providing what is necessary to understand the new billing format. The government has introduced Bill 58, a new legislation that includes a Customer Bill of Rights. Although this is a good initiative, it does not help the thousands of people who were misled and locked into long-term contracts. It was recommended that immediate action must be taken in the retail sector to maintain customer confidence

To compare the retail distribution and density per population of electronic and conventional cigarettes in smoke-free communities with and without e-cigarette restrictions. A cross-sectional study with field observations of retail tobacco stores. Two Central Kentucky counties with 100% smoke-free workplace regulations; counties selected on the basis of whether e-cigarette use was restricted. Fifty-seven tobacco retailers in two counties, including conventional retailers and stand-alone e-cigarette stores. Type and location of store and products sold; addresses of stores and schools geocoded with ArcGIS. Bivariate comparisons between counties, rates and confidence intervals for frequency of tobacco retailers and e-cigarette stores per population. Fifty-three percent of tobacco retailers sold e-cigarettes. E-cigarette availability did not differ by whether smoke-free regulation covered e-cigarettes. Rates of tobacco retailers and e-cigarette distributors per 10,000 were 8.29 and 4.40, respectively, in the two-county area. Of the 40 schools, 88% had a tobacco retailer and 68% had an e-cigarette distributor within 1 mile. In this exploratory study, e-cigarette use restriction was not related to store availability. For a relatively new product, e-cigarettes were readily available in retail outlets and close to schools.

Physicochemical Characteristics and Lipid Oxidation of Chicken Inner Fillets Subjected to Different Thermal Processing Types

Directory of Open Access Journals (Sweden)

NN Arguelo

Full Text Available ABSTRACT The objective of this study was to evaluate the effects of different types of thermal processing on the physiochemical characteristics and lipid oxidation of chicken inner fillets. The study was divided into three assays. In the first assay, 50 chicken inner fillets were divided into five treatments, totaling 10 samples per treatment. Treatments consisted in cooking in water bath, electric oven, microwave oven, deep frying, or grilling. The analyzed variables were: cooking weight loss (CWL and lipid oxidation determined by thiobarbituric acid reactive substances (TBARS. In the second assay, 50 chicken inner fillets were divided into five treatments, totaling 10 samples per treatment. Each treatment consisted of the same cooking methods applied in the first assay, and storage for 48 hours under refrigeration and reheating in a microwave oven. The variable analyzed in the second assay was lipid oxidation (TBARS. In the third assay, 30 samples of chicken inner fillets were subjected to one, four and eight freeze-thaw cycles, after which meat pH, myofibrillar fragmentation index (MFI, water retention capacity (WRC, and lipid oxidation (TBARS were determined. Chicken inner fillets submitted to deep frying and cooked in a microwave oven presented greater lipid oxidation than the other cooking methods, and deep frying resulted in the highest cooking weight loss. Reheating chicken inner fillets in a microwave oven caused the highest meat lipid oxidation. Increasing the number of freeze-thaw cycles increases the pH, MFI, WRC and TBARS values of chicken inner fillets.

Marketing Sustainable Retail Development

Directory of Open Access Journals (Sweden)

Dragan Ilić

2013-06-01

Full Text Available One of the primary benefits of sustainable retail over the long run has to be the marketing gain from having something other competitors do not: lower operating costs, a more socially responsible public profile, ease of gaining planning approval for new projects, better access to certain investment pools, higher rents (in the case of developers, ease of recruiting and retaining key people. Each of these benefits needs marketing and public relations support; each benefits from a clear and consistent corporate message that promotes sustainable retail. To date, there are very few retailers or developers who have championed sustainability long enough, consistently enough and with enough actual demonstration of changes in standard operations to gain the benefits of green marketing, but the very paucity of examples serves to underscore the point: the green marketing space is wide open for large retailers and developers. What would be the marketing steps that a company could take to benefit from its “sustainability focus?” The key to any marketing program is to differentiate a company’s actions from those of competitors and to do it along lines that its various stakeholders care about. This practice of differentiation is often expressed as “finding a difference that makes a difference, to someone who makes difference to you.” For retail developers, the first differentiator should be to attract more and better tenants to all of their centers, tenants who value lower operating costs and the developer’s program of sustainable development and corporate social responsibility.

Full Text Available The study was carried out to determine the effect of rapeseed meal (RSM on nutrient digestibility and intestinal parameters of jejunum of 21 days old broiler chickens. Three groups of Ross 308 chickens were formed and fed with corn-soy based feed (control group or feed with inclusion of 10% or 15% of rapeseed meal (low glucosinolate and low eruca acid content. All mixtures were balanced to the same energy and crude protein level.  To determine digestibility, 20 male chickens per treatment were put into metabolic cages. Digestibility was determined by using the method of total collection. Digestibility of dry matter, organic matter, crude protein, fat and energy was determined. At 21 days of age, chickens were sacrificed to obtain samples for morphometric parameters of jejunum. On jejunal samples, villus height and area, crypt depth and villus to crypt ratio were measured as indicators of gut integrity. No significant differences (P>0.05 were observed in any measured digestibility or gut health parameter. Addition of up to 15% of rapeseed meal in well balanced diets of young broiler chicken does not have an adverse effect on both digestibility of nutrients and broiler gut health.

Recently, deoxynivalenol-3-sulfate (DON-3-sulfate) was proposed as a major DON metabolite in poultry. In the present work, the first LC-MS/MS based method for determination of DON-3-sulfate, deepoxy-DON-3-sulfate (DOM-3-sulfate), DON, DOM, DON sulfonates 1, 2, 3, and DOM sulfonate 2 in excreta samples of chickens and turkeys was developed and validated. To this end, DOM-3-sulfate was chemically synthesized and characterized by NMR and LC-HR-MS/MS measurements. Application of the method to excreta and chyme samples of four feeding trials with turkeys, chickens, pullets, and roosters confirmed DON-3-sulfate as the major DON metabolite in all poultry species studied. Analogously to DON-3-sulfate, DOM-3-sulfate was formed after oral administration of DOM both in turkeys and in chickens. In addition, pullets and roosters metabolized DON into DOM-3-sulfate. In vitro transcription/translation assays revealed DOM-3-sulfate to be 2000 times less toxic on the ribosome than DON. Biological recoveries of DON and DOM orally administered to broiler chickens, turkeys, and pullets were 74%-106% (chickens), 51%-72% (roosters), and 131%-151% (pullets). In pullets, DON-3-sulfate concentrations increased from jejunum chyme samples to excreta samples by a factor of 60. This result, put into context with earlier studies, indicates fast and efficient absorption of DON between crop and jejunum, conversion to DON-3-sulfate in intestinal mucosa, liver, and possibly kidney, and rapid elimination into excreta via bile and urine.

The analysis of food products retailing in European Union

Directory of Open Access Journals (Sweden)

Rapaić Stevan

2009-01-01

Full Text Available Author is analyzing a share of food products in the structural profile of retail trade in European Union by presenting areas of retailing in which food, beverages, and tobacco products are predominant. The main task of retailing is to overcome gaps in time and space between production and consumption, in order to meet the needs of consumers. This main task of retailing becomes more difficult considering the fact that the European Union consists of demanding consumers that expect all products, especially food, to be served to them at the most accessible places, in most suitable time, and with prices that coincide with the worth of products. In the structure of retail trade of the European Union, food products can be found in sector of non-specialised in-store retailing (hypermarkets, supermarkets, Cash&Carry stores as well as in sector of specialised in-store food retailing (butcher shops, bakeries, fish markets, etc.. Restructure of retailing, internationalization, and concentration of total retail trade network are only some of the basic trends in contemporary retail sale of food products in the European Union, that are being explored in this text.

Avian hepatitis E virus (HEV) infection is common in chicken flocks in China, as currently no measures exist to prevent the spread of the disease. In this study, we analyzed the effect of caged versus cage-free housing arrangements on avian HEV transmission. First, 127 serum and 110 clinical fecal samples were collected from 4 chicken flocks including the two arrangements in Shaanxi Province, China and tested for HEV antibodies and/or virus. Concurrently, 36 specific-pathogen-free chickens were divided equally into four experimental living arrangement groups, designated cage-free (Inoculated), caged (Inoculated), cage-free (Negative) and caged (Negative) groups. In caged groups, three cages contained 3 chickens each. Three chickens each from cage-free (Inoculated) and caged (Inoculated) groups (one chicken of each cage) were inoculated by cutaneous ulnar vein with the same dose of avian HEV, respectively. The cage-free (Negative) and caged (Negative) groups served as negative control. Serum and fecal samples were collected at 1 to 7 weeks post-inoculation (wpi) and liver lesions were scored at 7 wpi. The results of serology showed that the avian HEV infection rate (54.10%) of the cage-free chickens was significantly higher than the one (12.12%) for caged chickens (P chickens (6) was significantly higher than the one for the uninoculated caged birds (2), as evidenced by seroconversion, fecal virus shedding, viremia and gross and microscopic liver lesions. These results suggest that reduction of contact with feces as seen in the caged arrangement of housing chickens can reduce avian HEV transmission. This study provides insights for prevention and control of avian HEV infection in chicken flocks.

Separation procedures utilizing ultrafiltration, Sephadex G-15 and reversed-phase high-performance liquid chromatography were used to isolate umami taste peptides. Combined with sensory evaluation and LC-Q-TOF-MS, the amino acid sequences of 12 oligopeptides were determined. The amount of taste compounds was higher in chicken enzymatic hydrolysate than that of chicken soup. Eight oligopeptides from chicken enzymatic hydrolysate were identified, including Ala-Asp, Ala-Met, His-Ser, Val-Glu, Ala-Glu, Asp-Ala-Gly, Glu-Asp and Ala-Glu-Ala. Four oligopeptides from chicken soup were identified, including Val-Thr, Ala-His, Ala-Phe and Thr-Glu. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of the study was to compare three types of meat snacks made from ostrich, beef, and chicken meat in relation to their nutrients content including fat, fatty acids, heme iron, and peptides, like anserine and carnosine, from which human health may potentially benefit. Dry meat samples were produced, from one type of muscle, obtained from ostrich ( m. ambiens ), beef ( m. semimembranosus ), and broiler chicken meat ( m. pectoralis major ). The composition of dried ostrich, beef, and chicken meat, with and without spices was compared. We show that meat snacks made from ostrich, beef, and chicken meat were characterized by high concentration of nutrients including proteins, minerals (heme iron especially in ostrich, than in beef), biologically active peptides (carnosine-in beef, anserine-in ostrich then in chicken meat). The, beneficial to human health, n -3 fatty acids levels differed significantly between species. Moreover, ostrich jerky contained four times less fat as compared to beef and half of that in chicken. In conclusion we can say that dried ostrich, beef, and chicken meat could be a good source of nutritional components.

The aim of this investigation was to study the possibility of detecting irradiated chicken and fish meats by the determination of Gram negative bacteria combined with the determination of endotoxin concentrations. Samples of chicken breast with skin, skinless chicken breast and eviscerated Bolti fish (Tilabia nilotica) were irradiated at room temperature at doses of 0, 1.5 and 3 kGy followed by storage at refrigeration temperature (4 ± 1 degree C) for 12 days or frozen storage at -18 degree C for 60 days. Furthermore, other samples of chicken and Bolti fish were irradiated in the frozen sate at doses of 0, 3, and 7 kGy followed by frozen storage at - 18 degree C for 60 days. Then the enumeration of Gram negative bacteria in conjunction with the determination of endotoxin concentrations were carried out for both irradiated and non-irradiated samples post treatments and during storage in addition to the discovery of Pseudomonas spp. The obtained results showed that chicken and fish samples irradiated at dose of 1.5 kGy could be identified during refrigerated storage for 6 and 9 days, respectively, while all samples irradiated at dose of 3 kGy were identifiable during 12 days of refrigerated storage. Moreover, all irradiated and frozen stored samples were identifiable during their frozen storage (- 18 degree C). The absence of Pseudomonads in all irradiated samples may aid in the differentiation of irradiated and non-irradiated samples especially during refrigerated storage. This method can be applied as a general screening method to predict the possible treatment of chicken and fish meats by ionizing radiation

Molecular detection of toxigenic potential of fungi in peanut samples collected in retail shops in Maringá/PR, Brazil

Full Text Available Many foods are susceptible to fungal contamination. Grains, such as peanuts, are commonly affected, with consequences including compromised integrity and infeasibility for human and animal consumption. Furthermore, some fungi may pose a health risk, largely due the production of mycotoxins. Among these, aflatoxins produced by Aspergillus flavus and A. parasiticus produce various carcinogenic, teratogenic, immunosuppressive, hepatotoxic and nephrotoxic effects. Molecular techniques have been used to identify and distinguish fungal species in foods. The objective of this study was molecular detection of Aspergillus species in peanut samples collected in stores in Maringá-PR, by amplification of fungal genetic material with specific primers for the intergenic spacer aflR-aflJ and later cutting with restriction enzymes. Of the 50 peanut samples analyzed, 27 were positive for the intergenic spacer aflR-aflJ, seven of which were identified as Aspergillus flavus. Our results demonstrate that peanuts sold in retail stores in this region have potential for contamination with toxigenic fungi.

The concentrations and enantiomer fractions (EFs) of α-, β-, and γ-hexabromocyclododecanes (HBCDs) were measured in chicken diet sources (soil and chicken feed), home-raised adult chicken (Gallus domesticus) tissues, eggs during incubation, and hatchling chicken tissues. HBCD concentrations were not detected-0.69 ng/g dry weight (dw) and 25.6-48.4 ng/g dw in chicken feed and soil, respectively. HBCDs were detected in all adult chicken tissues, except the brain, at median levels of 13.1-44.0 ng/g lipid weight (lw). The proportions of α-HBCD in total HBCDs increased from 51% in soil to more than 87% in adult chicken tissues. The accumulation ratios (ARs) of α-HBCD from diet to adult chicken tissues were 4.27 for liver, 11.2 for fat, and 7.64-12.9 for other tissues, respectively. The AR and carry-over rate (COR) of α-HBCD from diet to eggs were 22.4 and 0.226, respectively. The concentrations of α-HBCD in hatchling chicken liver (median: 35.4 ng/g lw) were significantly lower than those in hatchling chicken pectoral muscle (median: 130 ng/g lw). The EFs of α-HBCD decreased from soil to adult chicken tissues and from eggs to hatchling chicken liver. Meanwhile, the EFs of γ-HBCD increased from soil to adult chicken tissues. These results indicate the preferential enrichment of (-)-α-HBCD and (+)-γ-HBCD in chickens. The alteration of diastereoisomeric and enantiomeric patterns of HBCDs might be influenced by the different absorption and elimination rates of the six HBCD enantiomers as well as variations in HBCD metabolism in chickens.

Postprocessing contamination in processing plants has historically been a significant source of Listeria monocytogenes in ready-to-eat delicatessen meats, and therefore a major cause of human listeriosis cases and outbreaks. Recent risk assessments suggest that a majority of human listeriosis cases linked to consumption of contaminated deli meats may be due to L. monocytogenes contamination that occurs at the retail level. To better understand the ecology and transmission of Listeria spp. in retail delicatessens, food and nonfood contact surfaces were tested for L. monocytogenes and other Listeria spp. in a longitudinal study conducted in 30 retail delis in three U.S. states. In phase I of the study, seven sponge samples were collected monthly for 3 months in 15 delis (5 delis per state) prior to start of daily operation; in phase II, 28 food contact and nonfood contact sites were sampled in each of 30 delis during daily operation for 6 months. Among the 314 samples collected during phase I, 6.8% were positive for L. monocytogenes. Among 4,503 samples collected during phase II, 9.5% were positive for L. monocytogenes; 9 of 30 delis showed low L. monocytogenes prevalence (Listeria spp. isolates, including 184 Listeria innocua, 48 Listeria seeligeri, and 13 Listeria welshimeri were characterized. Pulsed-field gel electrophoresis (PFGE) was used to characterize 446 L. monocytogenes isolates. PFGE showed that for 12 of 30 delis, one or more PFGE types were isolated on at least three separate occasions, providing evidence for persistence of a given L. monocytogenes subtype in the delis. For some delis, PFGE patterns for isolates from nonfood contact surfaces were distinct from patterns for occasional food contact surface isolates, suggesting limited cross-contamination between these sites in some delis. This study provides longitudinal data on L. monocytogenes contamination patterns in retail delis, which should facilitate further development of control strategies in

How do minimum cigarette price laws affect cigarette prices at the retail level?

Science.gov (United States)

2005-04-01

Half of US states have minimum cigarette price laws that were originally passed to protect small independent retailers from unfair price competition with larger retailers. These laws prohibit cigarettes from being sold below a minimum price that is set by a formula. Many of these laws allow cigarette company promotional incentives offered to retailers, such as buydowns and master-type programmes, to be calculated into the formula. Allowing this provision has the potential to lower the allowable minimum price. This study assesses whether stores in states with minimum price laws have higher cigarette prices and lower rates of retailer participation in cigarette company promotional incentive programmes. Retail cigarette prices and retailer participation in cigarette company incentive programmes in 2001 were compared in eight states with minimum price laws and seven states without them. New York State had the most stringent minimum price law at the time of the study because it excluded promotional incentive programmes in its price setting formula; cigarette prices in New York were compared to all other states included in the study. Cigarette prices were not significantly different in our sample of US states with and without cigarette minimum price laws. Cigarette prices were significantly higher in New York stores than in the 14 other states combined. Most existing minimum cigarette price laws appear to have little impact on the retail price of cigarettes. This may be because they allow the use of promotional programmes, which are used by manufacturers to reduce cigarette prices. New York's strategy to disallow these types of incentive programmes may result in higher minimum cigarette prices, and should also be explored as a potential policy strategy to control cigarette company marketing practices in stores. Strict cigarette minimum price laws may have the potential to reduce cigarette consumption by decreasing demand through increased cigarette prices and reduced

USING OF COMBINED TREATMENT BETWEEN PROPOLIS (BEE GLUE) AND GAMMA RADIATION FOR EXTENDING SHELF-LIFE OF CHICKEN BURGER

International Nuclear Information System (INIS)

MATTAR, Z.A.; ABDELDAIEM, M.H.

2008-01-01

This investigation was carried out to extend the shelf-life of chicken burger using ethanol extract of propolis (EEP) at different concentrations (1 and 2%) as individual treatment using gamma irradiation at doses of 1.5, 3 and 4.5 kGy as individual treatment and combined treatments. The untreated and treated samples of chicken burger were divided into three groups, the first was control, the second group was chicken burger samples treated with 1% EEP then irradiated at doses of 1.5, 3 and 4.5 kGy and the third group was chicken burger samples treated with 2 % EEP then irradiated at doses of 1.5, 3 and 4.5 kGy. The effects of these treatments on the microbiological, chemical and sensory characteristics of chicken burger samples were studied post-treatment and during cold storage (4±1 0 C). The results showed that concentrations of EEP at 1 and 2% reduced the total bacterial count, lactic acid bacteria, Enterobacteriaceae total mold and yeast count, Staphylococcus aureus, Enterococccus faecalis and Bacillus cereus, and the growth of Salmonella spp, was not detected in all treated samples. Also, shelf-life periods were increased up to 27 days for chicken burger treated by 2% EEP and gamma radiation at dose of 4.5 kGy and these combined treatment were more effective as antimicrobial, consequently may be useful as natural food preservative

Intestinal Microbiota of Broiler Chickens As Affected by Litter Management Regimens

Science.gov (United States)

Wang, Lingling; Lilburn, Mike; Yu, Zhongtang

2016-01-01

Poultry litter is a mixture of bedding materials and enteric bacteria excreted by chickens, and it is typically reused for multiple growth cycles in commercial broiler production. Thus, bacteria can be transmitted from one growth cycle to the next via litter. However, it remains poorly understood how litter reuse affects development and composition of chicken gut microbiota. In this study, the effect of litter reuse on the microbiota in litter and in chicken gut was investigated using 2 litter management regimens: fresh vs. reused litter. Samples of ileal mucosa and cecal digesta were collected from young chicks (10 days of age) and mature birds (35 days of age). Based on analysis using DGGE and pyrosequencing of bacterial 16S rRNA gene amplicons, the microbiota of both the ileal mucosa and the cecal contents was affected by both litter management regimen and age of birds. Faecalibacterium, Oscillospira, Butyricicoccus, and one unclassified candidate genus closely related to Ruminococcus were most predominant in the cecal samples, while Lactobacillus was predominant in the ileal samples at both ages and in the cecal samples collected at day 10. At days 10 and 35, 8 and 3 genera, respectively, in the cecal luminal microbiota differed significantly in relative abundance between the 2 litter management regimens. Compared to the fresh litter, reused litter increased predominance of halotolerant/alkaliphilic bacteria and Faecalibacterium prausnitzii, a butyrate-producing gut bacterium. This study suggests that litter management regimens affect the chicken GI microbiota, which may impact the host nutritional status and intestinal health. PMID:27242676

The economics of gasoline retailing : petroleum distribution and retailing issues in the U.S

2005-03-31

Some of the controversies surrounding gasoline retailing prices in the United States were discussed with specific reference to zone pricing and non-price vertical restraints. Integrated refiners use a variety of often conflicting distribution methods to transport gasoline to consumers. The use of different retail provisions allows refiners to offer retail outlets to as many markets as possible, and these provisions have been the subject of antitrust scrutiny. Issues concerning refinery growth and capacity were reviewed along with brand management and federal standards. Various types of branded retail outlets were also discussed, along with company operated outlets and franchised dealer outlets. Issues concerning hypermarkets were examined and legal relationships between franchisers and franchisees in the petroleum industry were reviewed in relation to zone pricing. The motivation for non-price vertical restraints was considered, with reference to antitrust and anticompetitive behavior. It was suggested that the best way to analyze the gasoline sector is to examine the extent of margins in the sector. It was concluded that distribution channels help refiners market gasoline. Interactions between distribution channels can create competitive tensions in terms of brand free-riding and brand network operations. The use of price zones and non-price vertical restraints allow integrated refiners to offer retail distribution outlets across as many markets as possible. Antitrust scrutiny has not resulted in successful litigation as the refiners' actions are not expected to afflict consumers. 33 refs., 3 figs.

Recent incidents of foodborne illness associated with spices as the vehicle of transmission prompted this examination of U.S. retail spices with regard to Bacillus cereus. This study focused on the levels of aerobic-mesophilic spore-forming bacteria and B cereus spores associated with 247 retail spices purchased from five states in the United States. Samples contained a wide range of aerobic-mesophilic bacterial spore counts (spices had high levels of aerobic spores (> 10(7) CFU/g). Using a novel chromogenic agar, B. cereus and B. thuringiensis spores were isolated from 77 (31%) and 11 (4%) samples, respectively. Levels of B. cereus were spice isolates to form spores, produce diarrheal toxins, and grow at moderately abusive temperatures makes retail spices an important potential vehicle for foodborne illness caused by B. cereus strains, in particular those that produce diarrheal toxins.

Multi-strain infections and 'relapse' of Leucocytozoon sabrazesi gametocytes in domestic chickens in southern China.

Directory of Open Access Journals (Sweden)

Wenting Zhao

Full Text Available Leucocytozoon parasites infect many species of avian hosts, including domestic chicken, and can inflict heavy economic loss to the poultry industry. Although the prevalence and distribution of two Leucocytozoon species (L. sabrazesi and L. caulleryi have been reported in China previously, there are many questions related to the parasite infection that remain unanswered, including population diversity and transmission dynamics in domestic chickens. Here we surveyed chicken blood samples from seven sites in four provinces of China to identify Leucocytozoon infection, characterized parasite diversity within individual infected hosts and between sampling sites, and investigated the dynamics of gametocytemia in chickens over time. We found high infection rates in three of the seven sites. Clustering parasite sequences of the mitochondrial cytochrome oxidase III (coxIII and cytochrome b (cytb genes showed lack of grouping according to geographic origins and individual hosts carrying large numbers of L. sabrazesi strains. Monitoring gametocytemia in blood samples from infected chickens over time showed 'relapse' or persistence of low-level gametocytemia for 4-5 months, which could be explored as an in vivo model for testing drugs against liver stages of Apicomplexan parasites. This study provides important information on population diversity and transmission dynamics of L. sabrazesi and for disease control.

A retail audit of lamb loin tenderness was conducted over a 12-month period to determine the variation in tenderness of Australian lamb. Tenderness was objectively measured using Warner-Bratzler (WB) shear force. Muscle pH and cooking loss were determined on all samples and colour was measured on a sub-sample of loins. A total of 909 midloins from retail butcher shops and supermarkets located in four Australian capital cities (Sydney, Canberra, Melbourne, and Perth) were evaluated at four sampling times (December 1997 and March, June, and October 1998). Overall, 20.3% of all midloins purchased had a WB shear force value above the threshold level of 5 kg. Generic samples from Melbourne butcher shops were similar for WB shear force on average to the generic samples from Canberra and Sydney, whereas those from Melbourne supermarkets had significantly (Plamb had a greater WB shear force (Plamb. No relationship was found between price per kg and shear force (r=0.02) for loins purchased in Sydney (n=220). Price per kg differed between months (Plamb sold in the domestic market. A lamb eating quality assurance system, based on set protocols, is one approach that is currently being investigated in Australia to ensure the supply of consistently high eating quality lamb to consumers.

Full Text Available Foreign retailers are gaining progressively more of the Croatian retail market share. This paper is an analysis of the retail structure in the Republic of Croatia (sector G – 52, with respect to the origin of trading companies (domestic and foreign retailers, to their size (small, medium and large companies and to sub-sectors within a sector G – 52. The aim of this paper is to contribute to the understanding of causes underlying the foreign retailers’ expansion regarding their business success. The paper includes an analysis of the structure of household consumption in the Republic of Croatia as an important condition for the development of the retail structure. The analysis involves the indicators of domestic and foreign retailers’ business success: the turnover per one trading company and the turnover per one employee of the trading company. The comparison of these indicators for domestic and foreign retailers lead to certain differences (foreign retailers are slightly more productive than the domestic retailers and to the evaluation of the differences caused by the size of the company. Since a correlation of the size of the structure of domestic and foreign trading companies in certain sub-sectors within sector G –52 must not exist, the conclusion suggests itself in the form of a need to investigate other features of the retail structure. The research is related to the year 2001. Nevertheless, the research presented in the paper points at an inadequate adaptability of domestic retailers to the structure of demand in the Republic of Croatia as the cause of the insufficient trading success.

A meta-analysis of eight UK food studies was carried out to determine the microbiological quality of food and its relationship with the presence in food businesses of hazard analysis systems and food hygiene training. Of the 19,022 premises visited to collect food samples in these studies between 1997 and 2002, two thirds (66%) were catering premises and one third (34%) were retail premises. Comparison with PHLS Microbiological Guidelines revealed that significantly more ready-to-eat food samples from catering premises (20%; 2,511/12,703) were of unsatisfactory or unacceptable microbiological quality compared to samples from retail premises (12%; 1,039/8,462) (p catering premises (p catering premises (p catering) compared with premises where the manager had received food hygiene training (11% retail, 19% catering) (p catering) were from premises where there was no hazard analysis system in place compared to premises that had a documented hazard analysis system in place (10% retail, 18% catering) (p catering premises compared with those collected from retail premises may reflect differences in management food hygiene training and the presence of a hazard analysis system. The importance of adequate training for food handlers and their managers as a pre-requisite for effective hazard analysis and critical control point (HACCP) based controls is therefore emphasised.

Food waste occurs throughout the entire food supply chain, from production to consumption of food in households. Retailers are in a unique position to contribute to food waste avoidance, not only by minimizing the amount of waste in their distribution channels but also by influencing consumer...... attitudes and behaviors. This explorative study aims to identify which food waste avoidance actions are conducted by retailers in Denmark, to which extent, and how they vary across food categories and supermarket chain. Based on an analysis of secondary and empirical data collected via observations...... at retail stores, the authors identify 22 food waste avoidance actions in Danish retail. The results provide new insights into food waste avoidance in retail. Based on the findings, suggestions for further research directions are developed that should serve to identify the most efficient customer targeted...

Towards a sustainable development of retailing in Romania

2013-11-01

Full Text Available Sustainable development becomes increasingly important in the design of development policies. The economic field, due to the businesses it involves, is regarded as a tool capable of generating social well-being by caring for resource conservation. The retailing is part of this process, playing an important role due to the connection it provides between producers and consumers. The objectives of this study were to highlight the extent to which retailing developed in Romania, to measure the efficiency of firms in the industry and to identify sustainable development practices these firms used. In developing our approach a sample of 12 firms were selected, which were defined as constituting a reference framework based on their size and turnover. Further on, the descriptive research method was used, based on secondary sources of data investigation. After analyzing the data, it was concluded that the retailing sector in Romania is a powerful one, with a market slightly increasing, dominated by trends of concentration and with efficiency in line with the European average. The use of the principles of sustainable development into trade business companies in Romania is low. There is no urge to see these principles as business opportunities and sources of competitiveness.

3D Product authenticity model for online retail: An invariance analysis

Directory of Open Access Journals (Sweden)

Algharabat, R.

2010-01-01

Full Text Available This study investigates the effects of different levels of invariance analysis on three dimensional (3D product authenticity model (3DPAM constructs in the e- retailing context. A hypothetical retailer website presents a variety of laptops using 3D product visualisations. The proposed conceptual model achieves acceptable fit and the hypothesised paths are all valid. We empirically investigate the invariance across the subgroups to validate the results of our 3DPAM. We concluded that the 3D product authenticity model construct was invariant for our sample across different gender, level of education and study backgrounds. These findings suggested that all our subgroups conceptualised the 3DPAM similarly. Also the results show some non-invariance results for the structural and latent mean models. The gender group posits a non-invariance latent mean model. Study backgrounds group reveals a non-invariance result for the structural model. These findings allowed us to understand the 3DPAMs validity in the e-retail context. Managerial implications are explained.

A Closed-Loop Supply Chain Problem with Retailing and Recycling Competition

Full Text Available We investigate a durable product retailing and recycling problem in a closed-loop supply chain consisting of a single manufacturer and two competitive retailers, in which the manufacturer collects used products via retailers from the consumers and has sufficient channel power over the retailers to act as a Stackelberg leader; the retailers compete in retail products and recycling used products. In order to analyze the impact of retailing and recycling competitions on the profits of the manufacturer and the competitive retailers, two collection models (coordinated collection (Model C and decentralized collection (Model D are established, respectively. Then, based on game theory, we derive the optimal retail price, the optimal repurchase price, and the optimal profits of the manufacturer and the retailers. The managerial insights demonstrate that more intense retailing competition induces the increase of the manufacturer's profits in both forward and reverse channels and retailers' profits in the forward channel and the decrease of retailers' profits in the reverse channel, while more intense recycling competition induces the decrease of the profits of the manufacturer and retailers in both forward and reverse channels. Finally, numerical examples are given to illustrate the effectiveness of the proposed models.

2007-01-01

Full Text Available Retailing is carried on by those business which sell goods to the final consumer. The obvious example is provided by the shops we all know and deal with. The retailing stage, therefore, is the one where goods reach the end of their journey from the manufacturer. This does not that in those instances there is not retailing. The manufacturer or wholesaler who sells direct to the consumer is acting as a retailer; he adds retailing to his other activities. What ever channel of distribution is used, the retailing function always exists. In the past almost all retailers confined their activities to retailing; they did not combine it with other activities. These we can call “traditional” retailers. The functions of the traditional retailer where/and are: they break bulk into saleable portions; they put the goods in a saleable condition; they make goods immediately available to consumers; they measure consumer preferences. But the times have changed! In the “new” retailing the retailer provides a long range of services to whom he sells and to those from whom he buys. We’ll have in mind in this paper the refrigeration engineering and the “artificial cold”, the creative services at the point of sale (POS, the POS marketing, the marketing activities a the point of promotion (POP, the international diversity. In recent years most retail businesses tend to grow, and the statistics proves this, as it is shown in the paper.

Chicken embryonic stem cells (ESCs) were separated from blastoderms at stage-X and cultured in vitro. Alkaline phosphatase activity and stage-specific embryonic antigen-1 staining was conducted to detect ESCs. Then, chicken ESCs were transfected with linearized plasmid pEGFP-N1 in order to produce chimeric chicken. Firstly, the optimal electrotransfection condition was compared; the results showed the highest transfection efficiency was obtained when the field strength and pulse duration was 280 V and 75 μs, respectively. Secondly, the hatchability of shedding methods, drilling a window at the blunt end of egg and drilling a window at the lateral shell of egg was compared, the results showed that the hatchability was the highest for drilling a window at the lateral shell of egg. Thirdly, the hatchability of microinjection (ESCs was microinjected into chick embryo cavity) was compared too, the results showed there were significant difference between the injection group transfected with ESCs and that of other two groups. In addition, five chimeric chickens were obtained in this study and EGFP gene was expressed in some organs, but only two chimeric chicken expressed EGFP gene in the gonad, indicating that the chimeric chicken could be obtained through chick embryo cavity injection by drilling a window at the lateral shell of egg.

This research was conducted to investigate the effect of chicken feed additives (antibiotic, Lacto-lase® and probiotic) on protein and fat content of chicken meat. Chicken fed with control diet (corn-soy based diet) served as a control. The treated diets were added with zinc bacitracin (antibiotic), different amount of Lacto-lase® (a mixture of probiotic and enzyme) and probiotic. Chicken were slaughtered at the age of 43-48 days. Each chicken was divided into thigh, breast, drumstick, drumette and wing. Protein content in chicken meat was determined by using macro-Kjeldahl method meanwhile Soxhlet method was used to analyse fat content. The result of the study showed that the protein content of chicken breast was significantly higher (p≤0.05) while thigh had the lowest protein content (p≤0.05). Antibiotic fed chicken was found to have the highest protein content among the treated chickens but there was no significant different with 2g/kg Lacto-lase® fed chicken (p>0.05). All thighs were significantly higher (p≤0.05) in fat content except for drumette of control chicken while breast contained the lowest fat content compared to other chicken parts studied. The control chicken meat contained significantly higher (p≤0.05) amount of fat compared to the other treated chickens. Chicken fed with 2g/kg Lacto-lase® had the lowest (p≤0.05) fat content. The result of this study indicated that the addition of Lacto-lase® as a replacement of antibiotic in chicken feed will not affect the content of protein and fat of chicken meat.

The use of antibiotics in food animals is of public health concern, because resistant zoonotic pathogens can be transmitted to humans. Furthermore, global trade with food may rapidly spread multi-resistant pathogens between countries and even continents. The purpose of the study was to investigate whether imported chicken meat and meat from locally reared chicken are potential sources for human exposure to multi resistant Escherichia coli isolates. 188 samples from imported and locally produced chicken meat were sampled and analyzed. 153 bacteria isolates were successfully cultured and identified as E. coli using MALDI-ToF. Of these 109 isolates were from meat whereas the remaining 44 were isolated from the cloaca of locally reared live chickens. Antimicrobial susceptibility test was done on the identified E. coli isolates. Additionally, beta-lactamases production (ESBL and/or AmpC) were phenotypically confirmed on all isolates showing resistance to cefpodoxime. Beta-lactamase producing (BLP) E. coli meat isolates were further genotyped. Antimicrobial resistance to four antibiotic markers with highest resistance was detected more frequently in isolates from local chickens compared to imported chickens (tetracycline 88.9% vs. 57.5%, sulphonamide 75.0% vs. 46.6%, ampicillin 69.4% vs. 61.6% and trimethoprim 66.7% vs. 38.4%). Beta-lactamase production was found in 29 E. coli meat isolates, with 56.9% of them being multiple drug resistant (≥ 3). The predominant phylogroup identified was B1 followed by A and D, with similar distribution among the isolates from meat of locally reared chickens and imported chickens. Beta-lactamase producing genotype blaCTX-M-15 (50%; 10/20) was the most frequently drug resistant gene detected. More BLP E. coli isolates were found in imported chicken meat compared to locally reared chickens, demonstrating that these isolates may be spreading through food trade. In conclusion, both imported and locally produced chicken meats are potential

In anticipation of the full opening of the Ontario electricity market in November 2000, some of the newly-licensed electricity retailers are reported to be ready to begin testing the market early, hoping that all the uncertainties that still exist about pricing will be worked out in time. Among those jumping in now is Direct Energy Marketing, a retailer which claims 800,000 households in Ontario as electricity supply customers, as well as a wholesale gas marketing business. Direct Energy began retail electrical marketing on April 3, 2000, starting cautiously with small commercial operations as the initial target. Greengrid Electric, another of the new marketers, planned to begin marketing in mid-April, offering 100 per cent renewable-sourced electricity. Provident Energy Management, one of the new marketers whose licence is still pending, hopes to begin direct marketing as soon as its licence is confirmed. Another marketer ready to go as soon its license is issued is the former Sault Ste. Marie Hydro, now reorganized as PUC Energies Inc. PUC has the advantage of having a firm contract with a NUG (non-utility generator), Great Lakes Power, signed while PUC was still a municipal electric utility. As far as the other potential marketers are concerned, caution overrides opportunity for the present. Principal concerns are uncertainty over the retail settlement code, the electronic business data transfer system, transmission and distribution tariffs, whether existing non-utility generator contracts will allow for supply to another party, and over how quickly Ontario Power Generation Inc's (successor to Ontario Hydro) market power will be ratcheted down. Many of the potential marketers feel that despite the Ontario government's desire to see more competition, the power mitigation agreement, as it now reads, leaves little room for the small retailer to compete.

Fresh, chilled chicken carcasses were irradiated at 2.5 kGy and stored at 40 degree C. At intervals samples were withdrawn for microbial, chemical and sensory evaluation. Result showed that combination of a 2.5 kGy irradiation dose and storage at 4 degree C were adequate for a radicidised chicken process. Immediately after irradiation, the microbial spoilage was reduced by at least 4 log cycles. The carcasses were qf excellent quality for at least 16 days of storage and were free from Salmonella and other food pathogens. Changes in chemical composition (moisture, fat, protein, ash and amino acids) and sensory quality of chicken carcasses irradiated at 2.5 kGy were not significant. Therefore the dose of 2.5 kGy should be the target for chilled chicken irradiation process

A radioimmunoassay was developed for measurement of chicken plasma prolactin. The assay used chPRL(AFP-10328B) as reference standard, chPRL(AFP-4444B) as the radio labelled ligand, rabbit anti-chicken PRL (AFP-151040789) as first antibody, and donkey anti-rabbit IgG antiserum as second antibody. For iodide ratio labelling of chicken PRL, a modified chloramine T method which reduced the amount of chloramine T and omitted sodium metabisulfite, and produced the labelled hormone with a specific activity of 29μCi/μg was used. The assay sensitivity was 0.34 ng/ml. the ED75, ED50 and ED25 of standard curve were 1.30, 3.71 and 10.60 ng/ml, respectively. Both coefficients of variations between and within assay were less than 15%. Serial dilutions of chicken samples showed a parallel inhibition curve to that of the standards. Plasma PRL concentrations of samples from hens at different reproductive states measured by this assay revealed significant differences and rational changing trends. These results validate the assay

POLICIES OF RETAIL SECTOR OF INDIA AND OTHER SELECTED COUNTRIES

Full Text Available The retail sector is one of the fastest growing sectors in India. Before 1991, the retail sector was mainly unorganized and fragmented. The rapid growth of the organized retail sector has resulted in the decreasing sales of unorganized retail outlets. Along with that, the traditional unorganized retailers were lagging behind in the context of promotional strategies. This study intends to examine the government policies of different countries including India regarding the unorganized and organized retail sector. The present study examines whether the government provides a tight legal framework along with economic support to the small and unorganized retailers to sustain in this big fight. The study concludes that in the environment of intense competition, governments of different countries (including India had helped small as well as big domestic retail chains through formulating appropriate policies over time. The governments had helped domestic retail chains by providing capital support and/or formulating strict legislations to restrict entry of foreign retailers in their respective countries. In India, all the regulations regarding retail sector is still in state level and is being influenced by the existing political parties of different states. Thus, it varies across states and their impacts are also heterogeneous.

The author studied the conditions needed to routinely estimate the radiation dose in chicken bone by repeated re-irradiation and measuring ESR signals. Chicken meat containing bone was γ-irradiated at doses of up to 3kGy, accepted as the commercially used dose. The results show that points in sample preparation and ESR measurement are as follows: Both ends of bone are cut off and central part of compact bone is used for experiment. To obtain accurate ESR spectrum, marrow should be scraped out completely. Sample bone fragments of 1-2mm particle size and ca.100mg are recommended to obtain stable and maximum signal. In practice, by re-irradiating up to 5kGy and extrapolating data of the signal intensity to zero using linear regression analysis, radiation dose is estimated. For example, in one experiment, estimated doses of chicken bones initially irradiated at 3.0kGy, 1.0kGy, 0.50kGy and 0.25kGy were 3.4kGy, 1.3kGy, 0.81kGy and 0.57kGy. (author)

Supply chain-related game theoretical applications have been discussed for decades. This research accounts for the emergence of a dominant retailer, and the retailer Stackelberg pricing models of distribution channels. Research in the channel pricing game may use different definitions of pricing decision variables. In this research, we pay attentions to the retailer Stackelberg pricing game, and discuss the effects when choosing different decision variables. According the literature it was shown that the strategies between channel members depend critically on the form of the demand function. Two different demand forms—linear and non-linear—will be considered in our numerical example respectively. Our major finding is the outcomes are not relative to manufacturers' pricing decisions but to the retailer's pricing decision and choosing percentage margin as retailer's decision variable is the best strategy for the retailer but worst for manufacturers. The numerical results show that it is consistence between linear and non-linear demand form.

Consumer behavior in the context of online food retail channels is analyzed. The research is a follow-up to an earlier study conducted in early 1998 on consumer response to online food shopping. In the 1998 study (N=243), a majority of the sample (51 percent) were "new" users of online food shopping (6 months). In contrast, the new user segment in the follow-up study (N=412) was 29 percent; the intermediate segment was 28 percent; and the experienced group was 43 percent. Demographic profiles...

The genotypes and oxacillin resistance of 263 Staphylococcus aureus isolates cultured from chicken cloacae (n = 138) and chicken meat (n = 125) was analyzed. Fifteen spa types were determined in the studied S. aureus population. Among 5 staphylococcal protein A gene (spa) types detected in S. aureus from chicken, t002, t3478, and t13620 were the most frequent. Staphylococcus aureus isolates from meat were assigned to 14 spa types. Among them, the genotypes t002, t056, t091, t3478, and t13620 were dominant. Except for 4 chicken S. aureus isolates belonging to CC398, the remaining 134 isolates were clustered into multilocus sequence clonal complex (CC) 5. Most of meat-derived isolates were assigned to CC5, CC7, and CC15, and to the newly described spa-CC12954 complex belonging to CC1. Except for t011 (CC398), all other spa types found among chicken isolates were also present in isolates from meat. Four S. aureus isolated from chicken and one from meat were identified as methicillin-resistant S. aureus (MRSA) with oxacillin minimum inhibitory concentrations from 16 to 64 μg/mL. All MRSA were assigned to spa types belonging to ST398, and included 4 animal spa t011 SCCmecV isolates and 1 meat-derived spa t899, SCCmecIV isolate. Borderline oxacillin-resistant S. aureus (BORSA) isolates, shown to grow on plates containing 2 to 3 μg/mL of oxacillin, were found within S. aureus isolates from chicken (3 isolates) and from meat (19 isolates). The spa t091 and t084 dominated among BORSA from chicken meat, whereas t548 and t002 were found within animal BORSA. We report for the first time the presence of MRSA in chicken in Poland. We demonstrate that MRSA CC398 could be found in chicken meat indicating potential of introduction of animal-associated genotypes into the food chain. We also report for the first time the possibility of transmission of BORSA isolates from chicken to meat. ©2014 Poultry Science Association Inc.

Full Text Available Aim: The current study was the first of its kind taken upon indigenous ecotypes of the Karnataka in order to unravel the diversity details at 20 chicken microsatellite regions. Materials and Methods: 210 indigenous chicken belonging to six districts of Bangalore and Mysore division formed the target sample for the present study. The genomic deoxyribonucleic acid was isolated by phenol chloroform isoamyl alcohol method. A panel of 20 microsatellite regions, including 14 recommended by FAO and six identified from published scientific literature became the targeted chicken genomic region. 27-33 samples were successfully genotyped in each of the six ecotypes through simplex or multiplex polymerase chain reactions, polyacrylamide gel electrophoresis and silver staining for the selected microsatellite panel. Results: The chickens of Ramanagara and Chamrajnagara were most distant with a Nei’s genetic distance value of 0.22. The chickens of Bangalore rural and Mysore were least distant with a value of 0.056. The Ramanagara and Chamrajnagara pair had Nei’s genetic identity value of 0.802, which is least among all pairs of ecotypes. There were five main nodes from which the six ecotypes evolved on the basis 20 microsatellite markers used in this study. This study indicates that the four ecotypes Ramnagara, Bangalore Rural, Chickaballapura and Mysore are genetically identical due to their common ancestral evolution while, Mandya and Chamrajnagara ecotypes formed a relatively different cluster due to a separate common ancestral chicken population and less number of generations since drifting from bifurcation node. Conclusion: Twenty microsatellite markers based genetic diversity study on six indigenous ecotypes indicated lower genetic distances as well as lower FST values compared to the distinguished breeds reported. There were two main clusters, which differentiated into six ecotypes. They may differentiate into more distinct varieties if bred in
