  1. Brucella serology in abattoir workers

    Brucellosis is an occupational hazard with those particularly at risk either living in close proximity with animals or handling them. It is a public health problem in developing countries with adverse health implications both for animals and human beings as well as economic implications for individuals and communities. The Objectives were to estimate the seroprevalence of brucellosis among abattoir workers of Lahore District and to determine the association of brucellosis with nature of job of the workers. Data was collected in April 2008. It was a cross-sectional study in which four main slaughterhouses in Lahore were included. The slaughterhouse workers were divided into seven strata based on their nature of job: meat sellers, slaughterers, animal keepers, drivers, cleaners, loaders and vets/paravets. A total of 360 such workers were selected using stratified random sampling technique. Sampling frames for different strata were prepared and from each frame, proportionate numbers, were selected through simple random method using random number tables. Data was obtained using a questionnaire. Additionally blood samples were collected and analyzed for anti-Brucella Immunoglobulin G (IgG) using enzyme-linked immunosorbent assay (ELISA) technique. The seroprevalence of anti-Brucella IgG was found to be 21.7%. A statistically significant difference was observed between the immune status of the respondents and their nature of job (p=0.005), age groups (p=0.013), and duration of job (p=0.003). The disease is an important public health problem in Pakistan. The disease can be prevented in the slaughterhouse workers through the use of personal protective devices. Public health authorities should educate the general public regarding prevention of the disease with specific emphasis on people working in slaughterhouses. (author)

    Full Text Available The aim of the present study was to test a possible way of monitoring cattle carcass classification using a statistical approach. For that purpose the analysis of covariance (ANCOVA by SAS was used with the fixed effect of the abattoir, carcass weight (as a covariate and their interaction. The analysis was based on the relationship between carcass weight and conformation or fatness grades. We tested if the regression lines of individual abattoirs differ from the average. The analysis comprised data for young bulls of Simmental breed slaughtered in Slovenia in the period from 2007 to 2010 (52,624 records. Results showed that in many abattoirs the assessment of conformation and fatness deviates significantly from the average, i.e. regression lines for several abattoirs differ significantly from the average (population line. Differences were more important for the conformation than fatness. The statistical process control using the analysis of covariance can be used for additional monitoring of cattle carcass classification.

    Cystic echinococcosis (CE) is an important anthropozoonotic parasitic common in Algeria. The predominant life cycle of E. granulosus is a synanthropic cycle with domestic dogs as definitive hosts and livestock animals as intermediate hosts. Slaughter activity represents a potential source for dogs to access infected offal. The aim of the present study was to determine if the contact between dogs and potentially infected offal was possible in licensed abattoirs. Eighty-one private and public abattoirs located in eastern Algeria were assessed with respect to their level of protection against the intrusion of dogs.We have demonstrated that in 42 % of these abattoirs, dogs could easily come in contact with potentially parasitized offal. The most common incorrect practices were the dumping of offal freely into the environment, the feeding of dogs with offal, and the leaving of unattended offal in an unsealed chamber. Overall, some hazardous practices remained common customs of workers, and enough abattoirs remain non-compliant that the cattledog domestic cycle of CE is unlikely to be broken. Hence, some recommended measures to interrupt parasite transmission include the following: recognition of the importance of abattoirs in the maintenance of canine echinococcosis, the controlled and proper disposal of offal, the abolishment of the custom of feeding dogs with infected offal and improvements in the level of health education of abattoir staff.

    Full Text Available Background and Objective: Sarcocyst infection is one of the most common zoonotic protozoan diseases caused by different Sarcocystis spp. Given the importance of this infection in public health, the infection rate of macroscopic and microscopic sarcocysts in slaughtered goats was determined in Jahrom abattoir. Materials and Methods : Between April and June in 2011, six tissues including the esophagus, tongue, diaphragm, shoulder muscles, thigh muscles, and heart of 4925 slaughtered goats were inspected to detect macroscopic sarcocysts in Jahrom abattoir. To detect microscopic cysts, four tissue samples (esophagus, tongue, diaphragm, and heart from 400 goats free of macroscopic cysts were investigated randomly via impression smear and digestion method. Results: The infection rate of macroscopic cysts was 9.48% and the highest infection rate was observed in the esophagus (91.1%. There was no significant relationship between the infection rate of macroscopic cysts and the age or gender (p value >0.05. The infection rate of microscopic cysts was 59.5% and 100% via impression smear and digestion method, respectively. There was a significant relationship between the infection rate of microscopic cysts and age (p value =0.002, whereas the relationship between the infection rate and age did not constitute statistical significance (p value =0.700. Conclusion: The results showed that digestion method was the most sensitive method for the detection of sarcocystis in goats and 100% of the goats were infected by this method. Thus for the prevention of human infection, the meat should be frozen or cooked sufficiently before consumption irrespective of the results of carcass inspection.

Geophysical investigation of the Atenda area was carried out using Vertical Electrical Sounding (VES of Electrical Resistivity Method (ERM, Electrical Resistivity Tomography (ERT, and also, Very Low Frequency (VLF electromagnetic method. The geophysical investigation was carried out to determine the lithology of the study area, track the contaminant plume view and compute the depth to bedrock in the study area. It was observed that a strong correlation exist between leachates from the Atenda abattoir location and sampled wells in the immediate environment. A groundwater monitoring programme to determine groundwater quality status of wells in the neighbourhood of abattoirs is recommended for implementation to safeguard the health of innocent residents in the vicinity.

  14. The Impact of Physical and Ergonomic Hazards on Poultry Abattoir Processing Workers: A Review.

    Harmse, Johannes L; Engelbrecht, Jacobus C; Bekker, Johan L

    2016-02-01

    The poultry abattoir industry continues to grow and contribute significantly to the gross domestic product in many countries. The industry expects working shifts of eight to eleven hours, during which workers are exposed to occupational hazards which include physical hazards ranging from noise, vibration, exposure to cold and ergonomic stress from manual, repetitive tasks that require force. A PubMed, Medline and Science Direct online database search, using specific keywords was conducted and the results confirmed that physical and ergonomic hazards impact on abattoir processing workers health, with harm not only to workers' health but also as an economic burden due to the loss of their livelihoods and the need for treatment and compensation in the industry. This review endeavours to highlight the contribution poultry processing plays in the development of physical agents and ergonomic stress related occupational diseases in poultry abattoir processing workers. The impact includes noise-induced hearing loss, increased blood pressure, menstrual and work related upper limb disorders. These are summarised as a quick reference guide for poultry abattoir owners, abattoir workers, poultry associations, occupational hygienists and medical practitioners to assist in the safer management of occupational health in poultry abattoirs.

    2013-01-01

    Objective: To assess the food safety knowledge and practices in meat handling, and to determine microbial load and pathogenic organisms in meat at Mekelle city. Methods: A descriptive survey design was used to answer questions concerning the current status of food hygiene and sanitation practiced in the abattoir and butcher shops. Workers from the abattoir and butcher shops were interviewed through a structured questionnaire to assess their food safety knowledge. Bacterial load was assessed by serial dilution method and the major bacterial pathogens were isolated by using standard procedures. Results: 15.4% of the abattoir workers had no health certificate and there was no hot water, sterilizer and cooling facility in the abattoir. 11.3% of the butchers didn't use protective clothes. There was a food safety knowledge gap within the abattoir and butcher shop workers. The mean values of bacterial load of abattoir meat, butcher shops and street meat sale was found to be 1.1×105, 5.6×105 and 4.3×106 cfu/g, respectively. The major bacterial pathogens isolated were Escherichia coli, Staphylococcus aureus and Bacillus cereus. Conclusions: The study revealed that there is a reasonable gap on food safety knowledge by abattoir and butcher shop workers. The microbial profile was also higher compared to standards set by World Health Organization. Due attention should be given by the government to improve the food safety knowledge and the quality standard of meat sold in the city.

  5. A study of preslaughter pig handling and stunning in selected South African Highveld Region abattoirs

    B.T. Spencer

    2010-05-01

    Full Text Available The study hypothesis was that pre-slaughter handling is not conducted in such a way that pigs can be considered humanely slaughtered, nor is it conducive to promoting those properties of fresh meat that could enhance pork quality. The 1st phase of the investigation was aimed at confirming the present compliance level within the prescribed norms. To this end the importance of stunning induction requirements for effective electrical stunning, the welfare implications relating to the pre-slaughter handling of pigs and the stunning and sticking techniques were investigated. Pre-slaughter welfare of the pigs at the abattoir was found to be influenced at the outset by the origin and type of pig slaughtered, the daily throughput range of pigs and the type of abattoir involved. A disappointing pre-arrival aspect was that deficiencies in road motor vehicles were observed while off-loading pigs. Through poor design or lack of maintenance, another factor that hampered free movement of pigs was the off-loading facilities. The nature of animal behaviour in the pens, in the passages and when going into the stunning area was directly related to the pig handling efficiency and to the nature and extent of design and maintenance problems with equipment. None of the abattoirs had a well designed in-feed to a well planned stunning area / facility, and a very high level of pig pre-slaughter stress prevailed. The optimum position of the electrodes is virtually impossible to attain under practical conditions and the practice of repeat application of electrical stunning is common. Of the total sample size (n = 1175, 34% were difficult to shackle, 90% of these being from the abattoirs tending to slaughter more routinely a wide range of different sized pigs. In this survey 149 pigs (13 % required more than a single sticking attempt to bleed out properly, considerably higher than in other published reports.

  7. Human and canine echinococcosis infection in informal, unlicensed abattoirs in Lima, Peru.

    Maria M Reyes

    Full Text Available Echinococcus granulosus infections are a major public health problem in livestock-raising regions around the world. The life cycle of this tapeworm is sustained between dogs (definitive host, canine echinococcosis, and herbivores (intermediary host, cystic hydatid disease. Humans may also develop cystic hydatid disease. Echinococcosis is endemic in rural areas of Peru; nevertheless, its presence or the extension of the problem in urban areas is basically unknown. Migration into Lima, an 8-million habitant's metropolis, creates peripheral areas where animals brought from endemic areas are slaughtered without veterinary supervision. We identified eight informal, unlicensed abattoirs in a peripheral district of Lima and performed a cross-sectional study in to assess the prevalence of canine echinococcosis, evaluated by coproELISA followed by PCR evaluation and arecoline purge. Eight of 22 dogs (36% were positive to coproELISA, and four (18% were confirmed to be infected with E. granulosus tapeworms either by PCR or direct observation (purge. Later evaluation of the human population living in these abattoirs using abdominal ultrasound, chest X-rays and serology, found 3 out of 32 (9.3% subjects with echinococcal cysts in the liver (two viable, one calcified, one of whom had also lung involvement and a strongly positive antibody response. Autochthonous transmission of E. granulosus is present in Lima. Informal, unlicensed abattoirs may be sources of infection to neighbouring people in this urban environment.

    Purpose This study aims to investigate the occupational hazards among the abattoir workers associated with noncompliance to the meat processing and waste disposal laws in Terengganu State, Malaysia. Occupational hazards are the major source of morbidity and mortality among the animal workers due to exposure to many hazardous situations in their daily practices. Occupational infections mostly contracted by abattoir workers could be caused by iatrogenic or transmissible agents, including viruses, bacteria, fungi, and parasites and the toxins produced by these organisms. Materials and methods The methodology was based on a cross-sectional survey using cluster sampling technique in the four districts of Terengganu State, Malaysia. One hundred and twenty-one abattoir workers from five abattoirs were assessed using a validated structured questionnaire and an observation checklist. Results The mean and standard deviation of occupational hazards scores of the workers were 2.32 (2.721). Physical, chemical, biological, psychosocial, musculoskeletal, and ergonomics hazards were the major findings of this study. However, the highest prevalence of occupational hazards identified among the workers was injury by sharp equipment such as a knife (20.0%), noise exposure (17.0%), and due to offensive odor within the abattoir premises (12.0%). Conclusion The major occupational hazards encountered by the workers in the study area were physical, chemical, biological, psychosocial, musculoskeletal, and ergonomics hazards. To ensure proper control of occupational health hazards among the abattoir workers, standard design and good environmental hygiene must be taken into consideration all the time. Exposure control plan, which includes risk identification, risk characterization, assessment of workers at risk, risk control, workers’ education/training, and implementation of safe work procedures, should be implemented by the government and all the existing laws governing the abattoir

    2010-08-01

    Full Text Available Abstract Background Ontario provincial abattoirs have the potential to be important sources of syndromic surveillance data for emerging diseases of concern to animal health, public health and food safety. The objectives of this study were to: (1 describe provincially inspected abattoirs processing cattle in Ontario in terms of the number of abattoirs, the number of weeks abattoirs process cattle, geographical distribution, types of whole carcass condemnations reported, and the distance animals are shipped for slaughter; and (2 identify various seasonal, secular, disease and non-disease factors that might bias the results of quantitative methods, such as cluster detection methods, used for food animal syndromic surveillance. Results Data were collected from the Ontario Ministry of Agriculture, Food and Rural Affairs and the Ontario Cattlemen's Association regarding whole carcass condemnation rates for cattle animal classes, abattoir compliance ratings, and the monthly sales-yard price for various cattle classes from 2001-2007. To analyze the association between condemnation rates and potential explanatory variables including abattoir characteristics, season, year and commodity price, as well as animal class, negative binomial regression models were fit using generalized estimating equations (GEE to account for autocorrelation among observations from the same abattoir. Results of the fitted model found animal class, year, season, price, and audit rating are associated with condemnation rates in Ontario abattoirs. In addition, a subset of data was used to estimate the average distance cattle are shipped to Ontario provincial abattoirs. The median distance from the farm to the abattoir was approximately 82 km, and 75% of cattle were shipped less than 100 km. Conclusions The results suggest that secular and seasonal trends, as well as some non-disease factors will need to be corrected for when applying quantitative methods for syndromic surveillance

  10. Disparities in Beef Tapeworm Identification Rates in the Abattoirs of Gauteng Province, South Africa: A Descriptive Epidemiologic Study.

    Daniel Nenene Qekwana

    Full Text Available Bovine Taenia saginata cysticercus infections (also called bovine cysticercosis or beef measles is usually diagnosed in cattle only during post-mortem meat inspection. The aim of this study was to investigate the identification rates of these infections in and to identify predictors/determinants of variations in the identification rates in abattoirs in Gauteng province, South Africa.Retrospective data for over 1.4 million cattle carcasses inspected in 26 abattoirs between January 2010 and December 2013 were used for the study. The identification rates (proportion of bovine Taenia saginata cysticercus positive carcasses were computed and generalized estimating equations used to identify predictors/determinants of identification rates.The overall identification rate was 0.70% (95% CI: 0.45, 0.95. Significantly (p0.05 association was identified between identification rates and either the number of meat inspectors per abattoir or the provider of inspection services.Although no significant association was found between identification rates and provider of inspection services, follow-up studies will need to be done to specifically investigate the potential conflict of interest arising from the fact that abattoir owners hire meat inspection services directly. Capture of abattoir surveillance data needs to include farm address and for each case to be reported separately. Finally, information on the type of identified cysts (alive or calcified need to be collected to help better estimate risk to consumers. This study provides useful baseline data to guide future studies, surveillance and control efforts.

    Full Text Available The bacteriological quality of beef produced from most abattoir located in southern Nigeria has always been questionable. This work therefore investigated the bacteriological quality of abattoir facilities from both government and private owned abattoirs located in southern Nigeria. The results of our findings revealed that the total heterotrophic counts and total coliform counts exceeded the recommended standard for sanitary practices. Total heterotrophic counts from air flora ranged from 14.50 x 106to 42.50 x 106cfu. Beef-contact surface ranged from 26.50 x 106to 592.50 x 106cfu while total colony counts obtained from wastewaters from both government and private abattoirs ranged from 140.00 x 106to 1206.75 x 106cfu/ml. The total coliform counts also ranged from 14.25 x 103to 33.75 x 103for air flora and 76.00 x 103to 195.00 x 103cfu/ml for wastewaters. Eight bacterial isolates were consistently isolated during this study, and they included; Escherichia coli, Staphylococcus aureus, Staphylococcus sp., Citrobacter sp., Alcaligenes paradoxus, Klebsiella sp. and Enterococcus faecalis with varying percentage of frequency across the sampling points. The presence of indicator organisms as well as possible pathogens in this study is of special concern and stakeholders should be encouraged to review the processes involved in the establishment as well as operation of abattoir in southern Nigeria.

An overall prevalence of 20% (64 positive was obtained with sex prevalence for males and females being 10.62% (34 positive and 9.37% (30 positive respectively out of 180 males and 140 females tested without significant association (P 24 months while; lower prevalence of 3.13% was recorded in age group

  13. Maternal slaughter at abattoirs: history, causes, cases and the meat industry

    Fayemi, Peter Olutope; Muchenje, Voster

    2013-01-01

    Animals of both sexes are slaughtered for meat and meat products at the abattoirs. It has been found in few countries that one-out-of-every-three ewe and one-out-of-every-four doe with single, twin or multiple foetuses are slaughtered in registered slaughterhouses. In quest for meat, numerous viable embryos and foetuses are wasted unnoticed since the productive pregnant animals are not spared in the process. The trend in the slaughter of pregnant animals for meat (ranging from 54.5% to 70.1%)...

Occupational hazards are the major source of morbidity and mortality among the animal workers due to exposure to many hazardous situations in their daily practices. Occupational infections mostly contracted by abattoir workers could be caused by iatrogenic or transmissible agents, including viruses, bacteria, fungi, and parasites and the toxins produced by these organisms. Materials and methods: The methodology was based on a cross-sectional survey using cluster sampling technique in the four districts of Terengganu State, Malaysia. One hundred and twenty-one abattoir workers from five abattoirs were assessed using a validated structured questionnaire and an observation checklist.

    2015-01-01

    Full Text Available The cytogenotoxic potential of abattoir effluent from Bodija, Nigeria, was investigated using micronucleus test in Clarias gariepinus. Fish was exposed to five different concentrations: 0.2, 0.4, 0.8, 1.6, and 3.1% of the effluent for 7, 14, and 28 days. Tap water and 0.02 mL/L of benzene were used as negative and positive controls, respectively. Physicochemical parameters and heavy metals were analyzed in the effluent in accordance with standard methods. After exposure, blood was collected from the treated and control fish and slides were prepared for micronuclei (MN and nuclear abnormality evaluation in the peripheral erythrocytes. The effluent induced significant (p<0.05 increase in the frequency of MN in a time dependent manner. Similarly, the frequency of total nuclear abnormalities (blebbing, notch, bud, binucleation, and vacuolation was higher in the exposed fish than the negative control. Electrical conductivity, nitrate, biochemical oxygen demand, chemical oxygen demand, arsenic, and copper analyzed in the effluent may have provoked the observed cytogenetic damage. The findings herein suggest the presence of clastogens and cytotoxins in Bodija abattoir wastewater which are capable of increasing genomic instability in aquatic biota.

    2009-01-01

    Full Text Available Abstract Background Bovine Tuberculosis is prevalent in Algeria despite governmental attempts to control the disease. The objective of this study was to conduct, for the first time, molecular characterization of a population sample of Mycobacterium bovis strains isolated from slaughter cattle in Algeria. Between August and November 2007, 7250 animals were consecutively screened at the abattoirs of Algiers and Blida. In 260 animals, gross visible granulomatous lesions were detected and put into culture. Bacterial isolates were subsequently analysed by molecular methods. Results Altogether, 101 bacterial strains from 100 animals were subjected to molecular characterization. M. bovis was isolated from 88 animals. Other bacteria isolated included one strain of M. caprae, four Rhodococcus equi strains, three Non-tuberculous Mycobacteria (NTM and five strains of other bacterial species. The M. bovis strains isolated showed 22 different spoligotype patterns; four of them had not been previously reported. The majority of M. bovis strains (89% showed spoligotype patterns that were previously observed in strains from European cattle. Variable Number of Tandem Repeat (VNTR typing supported a link between M. bovis strains from Algeria and France. One spoligotype pattern has also been shown to be frequent in M. bovis strains from Mali although the VNTR pattern of the Algerian strains differed from the Malian strains. Conclusion M. bovis infections account for a high amount of granulomatous lesions detected in Algerian slaughter cattle during standard meat inspection at Algiers and Blida abattoir. Molecular typing results suggested a link between Algerian and European strains of M. bovis.

  17. A retrospective study of the prevalence of bovine fasciolosis at major abattoirs in Botswana.

    Mochankana, M Ernest; Robertson, Ian D

    2016-01-01

    A retrospective study covering a period of ten years (2001-2010) was conducted using postmortem meat inspection records of the Department of Veterinary Services in Gaborone to determine the prevalence of bovine fasciolosis in Botswana. Meat inspection records of monthly and annual returns from the two main export abattoirs in the country were examined, as well as the data collected on the total number of cattle slaughtered and the number of livers condemned due to Fasciola gigantica infection. Only 1250 of the approximately 1.4 million cattle slaughtered were infected with F. gigantica (0.09%, 95% confidence intervals [CI] 0.0% - 0.3%). No distinct seasonal pattern was observed in condemnation rates of livers. However, the pattern of distribution of fasciolosis was higher (but not significant) in cattle that originated from areas with high rainfall and more permanent water bodies than those from relatively low rainfall areas with a transitory water system. It is recommended that a longitudinal survey should be carried out at the abattoirs and farms to determine the prevalence of the disease in cattle of different ages, sex and breed as well as the place of origin in the country. The present study indicated that the prevalence of fasciolosis in cattle is low and the disease is therefore of less significance in Botswana than other African countries for which information is available.

  18. The slaughter of increased numbers of pregnant cows in Tanga abattoir, Tanzania: A cause for concern?

    Emmanuel S. Swai

    2015-02-01

    Full Text Available Information on the level of foetal wastage in slaughtered cattle in Tanzania is limited. A three-month observational study (April – June 2014 of animals slaughtered at the Tanga abattoir in Tanga region, Tanzania was carried out to determine the number of pregnant cows slaughtered. The total number of cattle slaughtered during the study period was 3643, representing a monthly kill average of 1214 and a daily kill average of 40. Over 98% of the cattle presented to the abattoir for slaughter were local breed (Tanzania shorthorn zebu and most were above 3 years of age. Improved breeds of cattle represented only 1.3% of all slaughters. Of the cattle slaughtered, 2256 (61.9% were female and 1387 (38.1% were male. A total of 655 slaughtered cows were pregnant, representing a foetal wastage of 29.1%. Of the 655 recovered foetuses, 333 (50.8% were male and 322 (49.2% were female. Of the recovered foetuses, 25.8% were recovered in the first, 42.7% in the second and 31.6% in the third trimester. This study indicates cases of significant foetal losses, negatively impacting future replacement stock as a result of the slaughter of pregnant animals. The indiscriminate slaughter of pregnant cows suggests that existing animal welfare legislation is not sufficiently enforced and routine veterinary ante-mortem inspection of trade animals is failing to prevent the high level of foetal wastage.

  19. Bovine tuberculosis in Rwanda: Prevalence and economic impact evaluation by meat inspection at Société des Abattoirs de Nyabugogo-Nyabugogo Abattoir, Kigali

    Gervais Habarugira

    2014-02-01

    Full Text Available Despite the significant public health burden of bovine tuberculosis (bTB in Rwanda, the prevalence of bTB is poorly documented. This study was conducted to estimate the prevalence of bTB in cattle using gross examination of granulomatous lesions, to identify mycobacteria species in suspected samples, and to evaluate the economic impact of meat condemnation based on bTB-like lesions in the meat industry in Rwanda. Routine meat inspection was conducted at Société des Abattoirs de Nyabugogo (SABAN-Nyabugogo Abattoir. Tissue samples including 31 lymph nodes, 3 lungs and 2 livers were obtained from cattle of different ages with gross tuberculous lesions. Mycobacterium bovis was identified using microscopy with Kinyoun staining and isolation of mycobacterial species in culture on Löwenstein–Jensen and Colestos media, further identified using biochemical tests. Our findings, based on culture and postmortem results, show that the prevalence of bTB is 0.5%(0.587*148/16753, with an overall gross tuberculous lesion prevalence of 0.9% (148/16753. The presence of lesions were higher in cattle aged 2 years and older (1.6% vs. 0.6%, p < 0.05 and higher in females than in males (1.4% vs. 0.6%, p < 0.05. Of the 36 samples tested, 26 (72.2% were positive by microscopic examination with Kinyoun staining while M. bovis was culture-confirmed in 21 (58.7% cases. Bovine tuberculosis caused condemnation of 1683.5 kg of meat, resulting in an estimated loss of $4810. Our findings indicate that the prevalence of bTB in Rwanda is significant, and that bTB is a major cause of meat condemnation requiring continued implementation of surveillance and control measures. Furthermore, the results from this study also show important variations in sensitivity of the different tests that were used to determine the prevalence of bTB in cattle in Rwanda.

  20. Antimicrobial drug resistance of Escherichia coli isolated from poultry abattoir workers at risk and broilers on antimicrobials

    J.W. Oguttu

    2008-05-01

    Full Text Available Antimicrobial usage in food animals increases the prevalence of antimicrobial drug resistance among their enteric bacteria. It has been suggested that this resistance can in turn be transferred to people working with such animals, e.g. abattoir workers. Antimicrobial drug resistance was investigated for Escherichia coli from broilers raised on feed supplemented with antimicrobials, and the people who carry out evisceration, washing and packing of intestines in a high-throughput poultry abattoir in Gauteng, South Africa. Broiler carcasses were sampled from 6 farms, on each of which broilers are produced in a separate 'grow-out cycle'. Per farm, 100 caeca were randomly collected 5 minutes after slaughter and the contents of each were selectively cultured for E. coli. The minimum inhibitory concentration (MIC of each isolate was determined for the following antimicrobials : doxycycline, trimethoprim, sulphamethoxazole, ampicillin, enrofloxacin, fosfomycin, ceftriaxone and nalidixic acid. The same was determined for the faeces of 29 abattoir workers and 28 persons used as controls. The majority of isolates from broilers were resistant, especially to antimicrobials that were used on the farms in the study. Overall median MICs and the number of resistant isolates from abattoir workers (packers plus eviscerators tended to be higher than for the control group. However, no statistically significant differences were observed when the median MICs of antimicrobials used regularly in poultry and percentage resistance were compared, nor could an association between resistance among the enteric E. coli from packers and those from broilers be demonstrated.

    2013-01-01

    Objective:To establish and estimate incidence of contagious bovine pleuropneumonia(CBPP),using abattoir survey as a diagnostic tool in slaughtered cattle in Northern Tanzania.Methods:A total of 4460 cattle were slaughtered in five abattoirs in 3 northern zone regions(Arusha,Kilimanjaro and Tanga)during the period of January to May 2004.They were examined ante-mortem for‘pneumonia signs’,and‘characteristic contagious bovine pleuropneumonia(CBPP)lung lesions’.Results:Forty-one(0.91%)of the slaughtered cattle,the majority of which were Tanzania short horn zebu,had gross lung lesions suggestive of CBPP.The prevalence of lesions was significantly(P<0.05)higher in Karatu abattoir compared to others.No animal was detected to have lesion in Bomang’ombe abattoir.The most observed pneumonic signs included labored breathing(90%),dry cough(57%)and mucopurulent nasal discharge(47%).The gross characteristic CBPP pathological lesion,frequently encountered was left lung lesion(47%),pinkish lung(71%)and pleural adhesion(98%).Epidemiological reports show that the CBPP reported outbreaks increased from 19 in 2002,65 in 2003 and 18 in 2004(January-March).The corresponding number of reported deaths increased from 137 in 2002,269 in 2003 and 77 in 2004(January-March).Conclusions:It’s concluded from this study that CBPP is a problem in spite of the extensive awareness and vaccination campaigns.Nevertheless,a continued surveillance programme including routine checks of all cattle carcasses at the abattoir and subsequent epidemiological investigation of suspected cases are recommended.

    2015-06-01

    A cross-sectional study was carried out on sheep and cattle slaughtered at a New Zealand abattoir from September to November 2010 to investigate the supplier-specific shedding rate, renal carriage rate and seroprevalence of leptospires. In the 2008/2009 season, this abattoir experienced three human leptospirosis cases from 20 staff, of which two were hospitalized. Urine, kidney and blood samples were collected from carcasses of 399 sheep (six suppliers, 17 slaughter lines) and 146 cattle (three suppliers, 22 slaughter lines). The urine and kidney samples were tested by quantitative real-time PCR (qPCR), while serum samples (from coagulated blood samples) were tested by microscopic agglutination test (MAT). In total, 27% (73/274; 95% CI: 18-37) of urine samples tested positive by qPCR. Species-specific shedding rates (prevalence of positive urine qPCR) were 31% (95% CI: 17-48) for sheep and 21% (95% CI: 14-30) for cattle. For 545 kidney samples tested, 145 were qPCR positive (27%; 95% CI: 17-39). The average prevalence of kidney qPCR positivity was 29% (95% CI: 17-45) for sheep and 21% (95% CI: 15-28) for cattle. Three hundred and thirty of 542 sampled sheep and cattle had antibodies against Leptospira borgpetersenii serovar Hardjobovis (Hardjobovis) and/or Leptospira interrogans serovar Pomona (Pomona), based on reciprocal MAT titre ≥1 : 48 (overall seroprevalence of 61%; 95% CI: 48-73). Seroprevalence was 57% (95% CI: 40-72) for sheep and 73% (95% CI: 59-83) for cattle. Among the seropositive animals, 41% (70/170; 95% CI: 30-54) were shedding (tested positive by urine qPCR) and 42% (137/330; 95% CI: 30-54) had renal carriage (tested positive by kidney qPCR). Some risk management options for abattoirs or farms to prevent human leptospirosis infections include vaccination of maintenance hosts, the use of personal protective equipment, and the application of urine qPCR to detect shedding status of stock as surveillance and as an alert.

    2011-01-01

    The study's objectives were to determine herd- and animal-level prevalence and herd-level risk factors for Salmonella in dairy-bred veal calves at slaughter in Denmark. In total, 1296 faecal samples were collected at five cattle abattoirs in Denmark during 2007 2008. The animals came from 71...... randomly selected specialized veal-calf producers that delivered more than 100 animals to slaughter per year. Salmonella Dublin bacteria were isolated from 19 samples from 12 herds and Salmonella Typhimurium was isolated from one sample. The apparent prevalence of herds delivering Salmonella......-shedding animals to slaughter was 18% (95% CI 9-27). The overall estimated true prevalence of shedding calves at slaughter was 1.3%. Veal-calf herds that purchased animals from herds not classified as low risk in the Danish Salmonella surveillance programme had significantly (P = 0.03) higher risk of delivering...

    2015-12-01

    Fascioliasis, or trematode infestation, is an important disease caused by Fasciola hepatica and Fasciola gigantica. Both species are hepatic parasites that affect humans. We have examined the zoonotic aspects of fascioliasis. A total of 80 fresh liver samples were collected from 67 Kedah-Kelantan crossbred cattle and 13 Murrah buffalo at 4 local abattoirs in Perak, Malaysia. The samples were examined macroscopically to detect the presence of Fasciola spp. The results show 7.50% (6 of 80) of the animals were diagnosed with fascioliasis. Overall, 7.46% (5 of 67) and 7.69% (1 of 13) of cattle and buffalo samples were positive, respectively. There were only F. gigantica species identified in the samples. Our findings suggest that precautions should be taken because the disease has a zoonotic impact on public health. PMID:26868715

  5. Prevalence of African swine fever viral antigens in slaughter pigs at Nalukolongo abattoir, Kampala, Uganda

    P. Sajjakambwe,

    2011-05-01

    Full Text Available The underdevelopment of the African pig industry is widely attributed to African swine fever (ASF. Outbreaks of the disease occur in different parts of Uganda almost annually although cases are rarely confirmed. We conducted an abattoir based survey of ASF associated lymph node lesions to establish the status of the disease in apparently healthy pigs. Highly suspicious lesions were subjected to immunohistochemistry for viral antigen detection. Most lymph nodes with follicular necrosis, parenchymal haemorrhage and lymphoid depletion were positive to ASF antigens. Up to 22 (0.1% of the 258 pigs from which samples were collected were positive to ASF viral antigens. We conclude that domestic pigs in Uganda can act as reservoirs of the disease i.e. sustenance of the disease in pig populations may not be entirely dependent on the sylvatic cycle.

    2014-09-01

    This study evaluated the effect of alkaline industrial by-products such as flyash (FA) and redmud (RM) on phosphorus (P) mobilisation in abattoir wastewater irrigated soils, using incubation, leaching and plant growth (Napier grass [Pennisetum purpureum]) experiments. The soil outside the wastewater irrigated area was also collected and treated with inorganic (KH2PO4 [PP]) and organic (poultry manure [PM]) P treatments, to study the effect of FA and RM on P mobilisation using plant growth experiment. Among the amendments, FA showed the highest increase in Olsen P, oxalic acid content and phosphatase activity. The highest increase in Olsen P for PM treated non-irrigated soils showed the ability of FA and RM in mobilising organic P better than inorganic P (PP). There was over 85 % increase in oxalic acid content in the plant growth soils compared to the incubated soil, showing the effect of Napier grass in the exudation of oxalic acid. Both amendments (FA and RM) showed an increase in phosphatase activity at over 90 % at the end of the 5-week incubation period. The leaching experiment indicated a decrease in water soluble P thereby ensuring the role of FA and RM in minimising P loss to water bodies. FA and RM showed an increase in plant biomass for all treatments, where FA amended soil showed the highest increase as evident from FA's effect on Olsen P. Therefore, the use of FA and RM mobilised P in abattoir wastewater irrigated soils and increased biomass production of Napier grass plants through root exudation of oxalic acid. PMID:24862480

    2016-01-01

    Statutory recording of carcass lesions at the abattoir may have significant potential as a resource for surveillance of livestock populations. Food Standards Agency (FSA) data in Great Britain are not currently used for surveillance purposes. There are concerns that the sensitivity of detection, combined with other issues, may make the outputs unreliable. In this study we postulate that FSA data could be used for surveillance purposes. To test this we compared FSA data with BPHS (a targeted surveillance system of slaughtered pigs) and laboratory diagnostic scanning surveillance (FarmFile) data, from mid-2008 to mid-2012, for respiratory conditions and tail bite lesions in pigs at population level. We also evaluated the agreement/correlation at batch level between FSA and BPHS inspections in four field trials during 2013. Temporal trends and regional differences at population level were described and compared using logistic regression models. Population temporal analysis showed an increase in respiratory disease in all datasets but with regional differences. For tail bite, the temporal trend and monthly patterns were completely different between the datasets. The field trials were run in three abattoirs and included 322 batches. Pearson’s correlation and Cohen’s kappa tests were used to assess correlation/agreement between inspections systems. It was moderate to strong for high prevalence conditions but slight for low prevalence conditions. We conclude that there is potential to use FSA data as a component of a surveillance system to monitor temporal trends and regional differences of chosen indicators at population level. At producer level and for low prevalence conditions it needs further improvement. Overall a number of issues still need to be addressed in order to provide the pig industry with the confidence to base their decisions on these FSA inspection data. Similar conclusions, at national level, may apply to other livestock sectors but require further

    2010-08-01

    Full Text Available Abstract Background Bovine Tuberculosis (BTB is a widespread and endemic disease of cattle in Ethiopia posing a significant threat to public health. Regular surveillance by skin test, bacteriology and molecular methods is not feasible due to lack of resource. Thus, routine abattoir (RA inspection will continue to play a key role for national surveillance. We evaluated efficiency of RA inspection for diagnosis of Mycobacterium bovis infection and discussed its public health implications in light of a high risk of human exposure. Methods The study was conducted in five abattoirs: Addis Ababa, Adama, Hawassa, Yabello and Melge-Wondo abattoirs. The efficiency of routine abattoir (RA inspection was validated in comparison to detailed abattoir (DA inspection, followed by culture and microscopy (CM and region of difference (RD deletion analysis. Diagnostic accuracies (with corresponding measures of statistical uncertainty were determined by computing test property statistics (sensitivity and specificity and likelihood estimations using web-based SISA diagnostic statistics software. Post-test probability of detecting TB infected carcasses was estimated using nomograms. Agreement between RA and DA inspections was measured using kappa statistics. The study was conducted and reported in accordance with standards for reporting of diagnostic accuracy (STARD requirements. Both routine and detailed meat inspection protocols were performed on a subpopulation of 3322 cattle selected randomly from among 78,269 cattle slaughtered during the study period. Three hundred thirty seven carcasses identified through detailed meat inspection protocols were subjected to culture and microscopy; of the 337, a subset of 105 specimens for culture and microscopy were subjected to further molecular testing. Results There was a substantial agreement between RA and DA inspections in Addis Ababa (Kappa = 0.7 and Melge-Wondo abattoirs (Kappa = 0.67. In Adama, Hawassa and Yabello

    There is increasing interest in developing abattoir-based measures to assist in determining the welfare status of pigs. The primary aim of this study was to determine the most appropriate place on the slaughter line to conduct assessments of welfare-related lesions, namely apparent aggression-related skin lesions (hereafter referred to as 'skin lesions'), loin bruising and apparent tail biting damage. The study also lent itself to an assessment of the prevalence of these lesions, and the extent to which they were linked with production variables. Finishing pigs processed at two abattoirs on the Island of Ireland (n=1950 in abattoir A, and n=1939 in abattoir B) were used. Data were collected over 6 days in each abattoir in July 2014. Lesion scoring took place at two points on the slaughter line: (1) at exsanguination (slaughter stage 1 (SS1)), and (2) following scalding and dehairing of carcasses (slaughter stage 2 (SS2)). At both points, each carcass was assigned a skin and tail lesion score ranging from 0 (lesion absent) to 3 or 4 (severe lesions), respectively. Loin bruising was recorded as present or absent. Differences in the percentage of pigs with observable lesions of each type were compared between SS1 and SS2 using McNemar/McNemar-Bowker tests. The associations between each lesion type, and both cold carcass weight and condemnations, were examined at batch level using Pearson's correlations. Batch was defined as the group of animals with a particular farm identification code on a given day. The overall percentage of pigs with a visible skin lesion (i.e. score>0) decreased between SS1 and SS2 (Ppigs with a severe skin lesion increased numerically from SS1 to SS2. The percentage of pigs with a visible tail lesion and with loin bruising also increased between SS1 and SS2 (Ppigs with skin lesions, tail lesions and loin bruising (Ptail lesions and loin bruising are more visible on pig carcasses after they have been scalded and dehaired, and that this is when

    Twenty-two cases of pyrexial illness which occurred amongst workers in a country abattoir were investigated retrospectively for Q fever, brucellosis, and leptospirosis. In 18, the illness was shown to be Q fever. No diagnoses were established for the other four. The demonstration of circulating Q-fever-specific IgM globulin was instrumental in establishing the diagnosis in many of the cases.

    Full Text Available In recent times, many zoonotic diseases have emerged with serious negative consequences on humans. In the light of this, ante-mortem inspections were conducted, using body condition scoring to assess the health status of livestock presenting for slaughter, and to identify issues relating to meat inspection in four purposively selected government approved abattoirs in Benue State, Nigeria. The result of our assessment showed that 5.0% of the cattle and goats presented for slaughter during the investigation period were highly emaciated animals with a prevalence range of 0.0–12.1% with variance between abattoirs, whereas 37.9% were moderately emaciated and 57.2% had good body condition. Extreme emaciation was higher in cattle (6.7% compared to the goats (3.2%. The moderately high prevalence of emaciated animals intended for human consumption coupled with unorganized and inappropriate meat inspection in the studied abattoirs has serious public health implications. To prevent consumers from contacting zoonotic diseases, education of butchers and traders is necessary for thorough and effective inspections. In addition, animal traders should be encouraged to seek veterinary assistance for their sick animals. Meat inspectors should treat all emaciated animals as suspects, as emaciation could be a cause from underlying health problems.

  15. Losses associated with mortality of cattle and camels during transportation to Oko-Oba abattoir, Lagos State, Nigeria

    2010-03-01

    Full Text Available Many food animals meant for slaughter arrive at the Agege abattoir and lairage daily to be produced into wholesome meat for human consumption. These animals generally get to the abattoir packed in Lorries and transported over long distances for many days to get to their destinations. Over a period of 36 months (three years, a total of 1179492 cattle and 11403 camels arrived for slaughter at the abattoir for human consumption. Over the same period, 1197 cattle and 27 camels died in the course of transportation due to the stress and inhumane treatment during transport. All the animals that arrived dead in transit had their carcass totally condemned and destroyed resulting in substantial losses to cattle traders, butchers and the general citizenry. Some of the reasons for these mortalities associated with transportation included overcrowding, long transportation without resting, stress, poor access road networks and traders not adhering to minimal space requirement for animal transportation in a bid to increase their profit margins. Failure to address the issue of proper transportation of food animals are likely to lead to more losses of food animals during transportation.

  16. Maternal slaughter at abattoirs: history, causes, cases and the meat industry.

    Fayemi, Peter Olutope; Muchenje, Voster

    2013-12-01

    Animals of both sexes are slaughtered for meat and meat products at the abattoirs. It has been found in few countries that one-out-of-every-three ewe and one-out-of-every-four doe with single, twin or multiple foetuses are slaughtered in registered slaughterhouses. In quest for meat, numerous viable embryos and foetuses are wasted unnoticed since the productive pregnant animals are not spared in the process. The trend in the slaughter of pregnant animals for meat (ranging from 54.5% to 70.1%) therefore calls for a review to reminisce issues on slaughter reforms, emphasize its implication on losses of genetic materials and sustainability of meat production. As a way of ensuring that welfare quality® assessment is not compromised and cruelty is prevented during animal slaughter, the quantitation of housekeeping genes and naturally occurring microRNAs (miRNAs) are recommended for identifying candidate pain biomarkers. In order to respect consumers' right however, the manuscript suggests meat branding where the consumption of meat from pregnant animals is ethical. PMID:23577300

    The effect of increasing the organic loading rates (OLRs) on the performance of the anaerobic codigestion of olive mill (OMW) and abattoir wastewaters (AW) was investigated under mesophilic and thermophilic conditions. The structure of the microbial community was also monitored. Increasing OLR to 9g of chemical oxygen demand (COD) L(-1)d(-1) affected significantly the biogas yield and microbial diversity at 35°C. However, at 55°C digester remained stable until OLR of 12g of CODL(-1)d(-1) with higher COD removal (80%) and biogas yield (0.52Lg(-1) COD removed). Significant differences in the bacterial communities were detected between mesophilic and thermophilic conditions. The dominant phyla detected in the digester at both phases were the Firmicutes, Actinobacteria, Bacteroidetes, Synergistetes and Spirochaete. However, Verrucomicrobia, Proteobacteria and the candidate division BRC1 were only detected at thermophilic conditions. The Methanobacteriales and the Thermoplasmales were found as a high predominant archaeal member in the anaerobic sludge. PMID:26687494

    Full Text Available Goat serves as a major investment to most homes in Nigeria, mainly for provision of animal protein and income. The output of this animal is disturbed by Tsetse infestation which is the primary vector of Trypanosome. A survey of Trypanosomiasis of goat in Ikpa abattoir Nsukka, Enugu State, Nigeria was carried out between September and October 2010. This was aimed at determining the species of Trypanosome prevalent in the area and their infection rates among breeds of goat. 106 goats were sampled, among which 15(14.1% were positive for Trypanosome infection. The infection rates among the goat breeds were; Sokoto red (10.4% and West African Dwarf Goat (50.0%. The species of Trypanosome encountered were Trypanosoma vivax(66.7% and Trypanosoma brucei (33.3%. In the infection by sex, this was common among female goats in the various breeds examined and this stood as follows; 9.4% in Sokoto red and 4.7% in West African Dwarf goat. Considering the overall infection rate of Trypanosome in the breeds of goat in the study area, this was relatively high when compared with similar results in related areas; chemo prophylactic and insect control measures should be put in place to rescue the area.

    The study was aimed to provide basic information regarding reproductive status of Gaddi sheep reared by nomadic tribe of Himachal Pradesh. Female genitalia of Gaddi sheep (n=190) were collected from unorganized abattoirs around Palampur over a period of one and half years. Out of total genitalia examined, 80.53% were grossly normal and 19.47% had one or more genital abnormalities. Genital abnormalities were categorized as ovarian (5.26%), uterine (10.53%) and miscellaneous (3.68%). Amongst ovarian abnormalities are follicular cysts (3.16%) and ovaro-bursal adhesions (2.10%), which were recorded in Gaddi ewes. Uterine abnormalities include hydrometra (4.74%), pyometra (2.63%), mucometra (2.10%), endometritis (0.53%) and mummification (0.53%). Miscellaneous abnormalities include parovarian cysts (2.10%), parasitic cysts (1.05%) and nodules on both uterine horns (0.53%). Among the genital abnormalities in sheep, highest incidence (24.32%) was observed with hydrometra and lowest (2.7%) with each of endometritis, mummification and nodular growth on both uterine horns. Thus the uterus (54.07%) was most commonly affected, followed by the ovary (27.02%) and miscellaneous (18.91%) in ewes. In present study, 8.95% pregnant sheep were also slaughtered, with fetal age in majority of cases two months or less on the basis of CRL measurement which represents a huge economic loss.

    2012-01-01

    Full Text Available Abstract Background Abattoir data have the potential to provide information for geospatial disease surveillance applications, but the quality of the data and utility for detecting disease outbreaks is not well understood. The objectives of this study were to 1 identify non-disease factors that may bias these data for disease surveillance and 2 determine if major disease events that took place during the study period would be captured using multi-level modelling and scan statistics. We analyzed data collected at all provincially-inspected abattoirs in Ontario, Canada during 2001-2007. During these years there were outbreaks of porcine circovirus-associated disease (PCVAD, porcine reproductive and respiratory syndrome (PRRS and swine influenza that produced widespread disease within the province. Negative binomial models with random intercepts for abattoir, to account for repeated measurements within abattoirs, were created. The relationships between partial carcass condemnation rates for pneumonia and nephritis with year, season, agricultural region, stock price, and abattoir processing capacity were explored. The utility of the spatial scan statistic for detecting clusters of high partial carcass condemnation rates in space, time, and space-time was investigated. Results Non-disease factors that were found to be associated with lung and kidney condemnation rates included abattoir processing capacity, agricultural region and season. Yearly trends in predicted condemnation rates varied by agricultural region, and temporal patterns were different for both types of condemnations. Some clusters of high condemnation rates of kidneys with nephritis in time and space-time preceded the timeframe during which case clusters were detected using traditional laboratory data. Yearly kidney condemnation rates related to nephritis lesions in eastern Ontario were most consistent with the trends that were expected in relation to the documented disease outbreaks

    Full Text Available A total of 300 samples were collected from cattle slaughtered in the Beni-Suef abattoir in Egypt. Samples included muscle, liver and kidney. Animals were randomly selected from the slaughter line. The age of the slaughtered cattle was less than three years (18-30 months. Samples were packed separately in plastic bags, identified and stored at -18°C until analysis which was performed at the Max Rubner Institute in Kulmbach, Germany, for the following heavy metals residues: lead, cadmium, mercury, arsenic, chromium and nickel in beef muscle, liver and kidney samples. The results revealed that the overall mean residual levels of lead were 8.77 µg/kg, 42.70 µg/kg and 109.42 µg/kg fresh weight in muscle, liver and kidney samples, respectively, while the mean residual levels of cadmium were 1.40 µg/kg, 14.16 µg/kg and 62.56 µg/kg fresh weight, respectively, and the mean arsenic residual levels were 5.06 µg/kg, 4.64 µg/kg and 14.92 µg/kg fresh weight, respectively. The mean residual levels of mercury were 3.91 µg/kg, 5.81 µg/kg and 10.14 µg/kg fresh weight, respectively, and the residual levels of chromium were 11.20 µg/kg, 21.85 µg/kg and 25.49 µg/kg fresh weight, respectively. Finally, the mean residual levels of nickel were 21.17 µg/kg, 14.59 µg/kg and 34.95 µg/kg fresh weight, respectively. The mean values of all heavy metals examined were low and did not exceed the permissible limits adopted by different organisations. Most heavy metals accumulated in higher concentrations in the kidney in comparison to the liver and muscle.

    2012-10-01

    A 5-yr retrospective study in livestock slaughtered in abattoirs was carried out in Khuzestan Province (southwestern Iran) to determine the prevalence of parasitic infections responsible for condemnation of slaughtered animals' carcasses and viscera. The economic importance of such infections in terms of lost meat and offal were also estimated. Between 20 March 2006 and 19 March 2011, 125,593 cattle, 1,191,871 sheep, 240,221 goats, and 25,010 buffalos were slaughtered in the study area; the livers of 58,753 (3.7%; 95% confidence interval [CI]: 3.7-3.8%), the lungs of 34,522 (2.2%; 95% CI: 2.1-2.2%), and the carcasses of 78 (0.0049% 95% CI: 0.0048-0.0049%) of these animals were condemned. Proportions of liver, lung, and carcass condemnations during the 5-yr study period in buffalos were significantly greater than the other species (P Sarcocystis spp. cysts were found in ovine and buffalo muscles, whereas Taenia sp. cysticerci were detected in bovine muscle. Muscles of goats were devoid of any parasitic lesions. Parasites were responsible for 54.1% of the condemned organs or carcasses, with a retail value (based on market prices in 2011) of $1,148,181 (U.S.) ($137,880 for cattle, $602,699 for sheep, $280,955 for goats, and $126,647 for buffalos). The parasites contributing most to the condemnation of otherwise marketable organs and flesh were E. granulosus (29.2%) and F. hepatica (18.6%). These parasites clearly remain the most common, causing considerable economic loss in Khuzestan Province and, presumably, other areas of Iran. PMID:22568697

  4. Blood Collection from Local Abattoirs for Mass Production of Tsetse Flies to be used in the Sterile Insect Technique

    The mass production of tsetse flies (Glossina spp.) for the sterile insect technique (SIT) requires a supply of quality blood. For some years already cattle blood has been used as food for laboratory reared flies. The blood is collected from an abattoir using standard procedures. The collection procedures, handling and storage require aseptic conditions to avoid contamination of the blood, which could be fatal to the flies. Fly mortality caused by low quality blood endangers the success of mass rearing. To rear healthy flies with good survival and production the blood should be of good quality - free of contamination and with a packed cell volume (PCV) above 25%. The present work involved the seasonal collection of blood from abattoirs in the United Republic of Tanzania (Tanga, Arusha, Dodoma, Dar-es-salaam). Dodoma was identified as having the best conditions for blood collection. To assess the quality of the blood as a diet for tsetse, blood was screened for the presence of bacteria, and the pathogens were identified. Protocols were developed for blood quality assurance.

    Full Text Available Background: Linguatula serrata, one of the parasitic zoonoses, inhabits the canine respiratory system (final hosts. The objective of this study was to determine the prevalence rate of L. serrata nymphs in mesenteric lymph nodes (MLNs of cattle and buffaloes (intermediate hosts that were processed in the Ahvaz, Iran abattoir.Methods: During November 2010 to March 2011, 223 animals (119 cattle and 104 buffaloes, in differ­ent sex and three age groups (3 years old were sampled randomly at Ahvaz abattoir. Up to 35 grams of their mesenteric lymph nodes were examined separately for nymphal stages of L. serrata by digesting the samples with acid- pepsin method, collected the nymphs and counted under stereomicroscope.Results: Overall 37(16.6% of 223 animals were infected with L. serrata nymphs in their mesenteric lymph nodes. Prevalence of the infection in cattle and buffaloes were 16.8% and 16.3% respectively. The number of collected nymphs of MLNs was ranged from 1 to 16. No significant differences were seen in the infection rates between males and females (sexes and age groups in the cattle and buffa­loes (P <0.05.Conclusion: Linguatula serrata has an active life cycle in the studied area and a zoonotic potential for transmission between animal and human. Avoiding use of raw MLNs to dogs can help reduce the infection.

  7. Energy self-supply of large abattoir by sustainable waste utilization based on anaerobic mono-digestion

    Highlights: • Successful implementation of a new waste and energy concept to large size abattoir. • 85% of slaughterhouse waste accumulated converted to energy by anaerobic digestion. • Coverage of abattoirs’ electrical and thermal energy demand between 50% and 60%. • Reduction of main energy and disposal cost by 63%. • Reduction of greenhouse gas emissions by 79%. - Abstract: Abattoirs have a large number of energy intensive processes. Beside energy supply, disposal costs of animal by-products (ABP) are the main relevant cost drivers. In this study, successful implementation of a new waste and energy management system based on anaerobic digestion is described. Several limitations and technical challenges regarding the anaerobic digestion of the protein rich waste material had to be overcome. The most significant problems were process imbalances such as foaming and floatation as well as high accumulation of volatile fatty acids and low biogas yields caused by lack of essential microelements, high ammonia concentrations and fluctuation in operation temperature. Ultimately, 85% of the waste accumulated during the slaughter process is converted into 2700 MW h thermal and 3200 MW h electrical energy in a biogas combined heat and power (CHP) plant. The thermal energy is optimally integrated into the production process by means of a stratified heat buffer. The energy generated by the biogas CHP-plant can cover a significant share of the energy requirement of the abattoir corresponding to 50% of heat and 60% of electric demand, respectively. In terms of annual cost for energy supply and waste disposal a reduction of 63% from 1.4 Mio € to about 0.5 Mio € could be achieved with the new system. The payback period of the whole investment is approximately 9 years. Beside the economic benefits also the positive environmental impact should be highlighted: a 79% reduction of greenhouse gas emissions from 4.5 Mio kg CO2 to 0.9 Mio kg CO2 annually was achieved.

    Full Text Available Aim: The study was conducted to identify major causes of organs condemnation in cattle slaughtered at Adigrat municipal abattoir and to estimate the direct economic losses.Material and Methods: A cross sectional active abattoir survey, which involves both ante mortem and post mortem examinations, was conducted on 745 cattle from October 2012 to April 2013, and two years (September 2010 - September 2012 retrospective data on meat inspection records was also collected.Results: During ante mortem examination, in 114 (15.3% cattle various types of abnormalities were detected include; lacrimation (3.49%, pale mucus membrane (3.09%, nasal discharge (1.88%, hernia (1.48%, actinomycosis (1.34%, salivation (1.74%, lameness (0.54%, emaciation (0.41%, depression (0.41%, blindness (0.41%, local swelling (0.27% and rough hair coat (0.27%. Postmortem examination revealed that 131 (17.58% liver, 61 (8.19% lungs, 9 (1.21% kidneys and 2 (0.27% hearts were condemned due to various causes. Fasciolosis (9.26% was the main cause of liver condemnation followed by hydatid cyst (3.62% and cysticercus bovis (2.55%, respectively. The major causes of lung condemnation were hydatid cyst, emphysema and pneumonia accounting for 5.1, 1.61 and 1.07%, respectively. Hydronephrosis and cysticercus bovis were the major causes of kidney and liver condemnation with rate of 0.94 and 0.27%, respectively. Totally about 19,910.0 Ethiopian birr (1,083.83 USD was lost from organs condemnation during the active abattoir survey. From the retrospective data it was observed that liver and lung were the most condemned organs with condemnation rate of 17.72 and 7.53%, respectively. The major causes of organ condemnation were hydatid cyst (11.52%, cirrhosis (4.97%, fasciolosis (4.35%, cysticercus bovis (4.12% and hydronephrosis (1.21%, respectively. Consequently, the overall direct economical loss during the two years was estimated to be 83,890.0 Ethiopian birr (4,566.68 USD.Conclusion: The

  9. Implementation of a validated HACCP system for the control of microbiological contamination of pig carcasses at a small abattoir.

    Bryant, Jeffrey; Brereton, Donald A; Gill, Colin O

    2003-01-01

    To guide the implementation of a Hazard Analysis Critical Control Point (HACCP) system at a small abattoir, the microbiological conditions of pig carcasses at various stages of processing were assessed by enumerating total aerobes, coliforms, and Escherichia coli in samples collected from randomly selected sites on the carcasses. Those data indicated that carcasses were contaminated with bacteria mainly during dehairing and operations on the head. When carcasses were pasteurized after head removal, the numbers of total aerobes on dressed carcasses were reduced by about 1 order and the numbers of coliforms and E. coli were reduced by more than 2 orders of magnitude. Implementation of an HACCP system on the basis of the microbiological data gave cooled carcasses with mean numbers of total aerobes < 100/cm2, and mean numbers of coliforms and E. coli about 1/1000 cm2.

  10. Diversity of Mannheimia haemolytica and pasteurella trehalosi serotypes from apparently healthy sheep and abattoir specimens in the highlands of Wollo, North East Ethiopia.

    Sisay, T; Zerihun, A

    2003-01-01

    The prevalence and serotypic diversity of Mannheimia [Pasteurella] haemolytica and Pasteurella trehalosi from nasal swabs, sera and abattoir specimens from sheep in the highlands of Wollo, North East Ethiopia was investigated. Prevalence rates of 83% and 75% of these microorganisms were found in the serum samples and nasal swabs, respectively, from apparently healthy sheep. In a local abattoir, 205 lungs were investigated, 34% of which showed pneumonia, from which samples were collected from 51 lungs and the same number of corresponding tonsils. Mannheimia and Pasteurella species were isolated from 59% of these pneumonic lungs and 69% of the respective tonsils. M. haemolytica serotypes accounted for 41 (59%) and P. trehalosi for 11 (32%) of the isolates from the abattoir specimens. The majority (67%) of isolates from nasal swabs were P. trehalosi, M. haemolytica being isolated f rom 4 (13%) of the swabs. M. glucosida was isolated only from the tonsils. The predominant serotypes of the isolates from both the nasal swabs and the abattoir specimens were M. haemolytica A1 (17%) and P. trehalosi T4 (16%) and T3 (13%). P. trehalosi T15 was less commonly encountered, while M. haemolytica A9 and A13 were not isolated. Studies on sera from 100 sheep indicated that antibodies against M. haemolytica serotype A1 (14%) were most common, followed by A5 and A8 (each 10%) and A9 and P. trehalosi T3 (each 9%) and T4 (8%). Antibodies against M. glucosida or serotype All occurred in 2% of the sera. Multiple serotypes were common in all types of samples. The importance of including in vaccines the most prevalent serotypes involved in the pneumonia of sheep in the area is discussed. PMID:12625399

    Njisane, Yonela Z.; Muchenje, Voster

    2013-01-01

    The objective of this study was to determine the effect of municipal abattoir conditions and animal factors on avoidance-related behaviour (AB) of sheep at slaughter, bleeding times (BT) and mutton quality. The behaviour of 66 castrates and 19 ewes of different age categories was observed at three stages of slaughter. Higher behaviour scores indicated higher levels of AB. Time intervals between the start of blood flow and the time the flow changed from a constant stream into drips were record...

    2014-01-01

    Physiological and behavioural reactions of cattle to handling procedures in a commercial abattoir (electrical prodding actions and duration of the animals׳ stay in the stunning box) were evaluated and set in relation to sex, breed type, and carcass weight. A total of 192 cattle comprised of 45 bulls, 61 steers, and 86 heifers from different breed types (30 dairy breed, 70 beef breed, and 92 crossbreds) were observed from lairage to slaughter during one day. The frequency of electrical proddin...

    Swaby, H; Gregory, N G

    2012-01-01

    There is growing interest in using findings from post-mortem meat inspection as indicators of on-farm and preslaughter animal welfare. This study considered whether oesophago-gastric ulcers might be a useful feature in pigs. The stomachs of 9827 finishing pigs from 60 farms were examined to provide an estimate of the frequency of oesophago-gastric ulcers in England. Stomachs were graded using a four-point scale ranging from normal, hyperkeratotic, eroded or ulcerated with or without stenosis. Over 79% of stomachs had either an oesophago-gastric ulcer or visible pre-ulcerative changes, including hyperkeratosis of the epithelium lining the pars oesophagea. The frequency of severe ulceration (Grade 3) was 6%, and mild ulcers (Grades 1 and 2) 73%. There was a significantly higher frequency of oesophago-gastric lesions in the groups of pigs that were held at the abattoir overnight, compared with those slaughtered on the day of arrival. This could have been due to the combined effect of overnight fasting plus stress in an unfamiliar environment. However, the exact fasting times of the animals were unknown and so it was not possible to provide a precise assessment of the effect of feed withdrawal. PMID:21733635

  14. A Retrospective Survey of Fasciolosis and Dicrocoeliosis in Slaughtered Animals in Meisam Abattoir, Tehran, Iran (2005-2008

    Full Text Available Fasciolosis and dicrocoeliosis are endemic parasitic diseases in Middle East especially Iran, which making significant economic problems. This retrospective survey has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Meisam abattoir, in Tehran, Iran. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a three-year period (2005-2008 has been analyzed. The prevalence rates of fasciolosis and dicrocoeliosis in cattle were 2.20 % and 2.5 %, and the rates in sheep were 2.01 % and 5.83 %, respectively. The average annual direct economic loss incurred as a result of condemnation of ovine and bovine infected livers due to fasciolosis and dicrocoeliosis were estimated as high as 227,907 USD. The results of current survey revealed the rate of dicrocoeliosis is higher than fasciolosis. Our work proved that the highest frequency rate of the fasciolosis and dicrocoeliosis in cattle was in summer and spring, respectively. Whereas winter and autumn had the highest prevalence rate of fasciolosis and dicrocoeliosis in sheep.

    2015-06-01

    Sarcocystosis is a zoonotic disease caused by Sarcocystis spp. with obligatory two host life cycle generally alternating between an herbivorous intermediate host and a carnivorous definitive host. Some species of this coccidian parasite can cause considerable morbidity and mortality in cattle. The present study was set to investigate the prevalence of Sarcocystis spp. and type of cyst wall in slaughtered cattle of Karaj abattoir, Iran. For this purpose 125 cattle (88 males and 37 females) were investigated for the presence of macroscopic and microscopic Sarcocystis cysts in muscular tissues. No macroscopic Sarcocystis cysts were found in any of the samples. In light microscopy, 121 out of 125 cattle (96.8 %) had thin-walled cysts of Sarcocystis cruzi, while 43 out of them (34.4 %) had thick-walled Sarcocystis cyst. In this survey, the most infected tissue was esophagus and heart and the less was diaphragm. Thin-walled cysts (S. cruzi) mostly found in heart and skeletal muscle showed the less. However, thick-walled cyst (S. hominis or S. hirsuta) mostly were detected in diaphragm, heart muscle showed no thick-walled cyst. No significant relation was observed between age and sex and the rate of infection. The results showed that Sarcocystis cyst is prevalent in cattle in the North part of Iran and the evaluation of infection potential can be useful when considering control programs. PMID:26064016

    Full Text Available The discharge of industrial wastewater in the city of Moundou deteriorates the quality of surface and underground water and soils. In this study the physicochemical quality of industrial effluents was investigated in different seasons (summer, winter and rainy. Three sampling sites were used (Central Abattoir discharge, Cotontchad (soap and oil factory discharge, and Brewery discharge, for sampling from July 2013 to December 2014. The following physico-chemical parameters were determined: pH, Temperature, EC, dissolved oxygen, COD, BOD5, NO3,PO4,SO4. Also, the heavy metals: Cu, Cd, Mn, Ni, Pb, As, Zn, Cr, Fe, Al, was analyzed on spectrophotometers and results were compared with World Health Organization (WHO permissible limits. This study revealed that most parameters were much higher than the permissible limit for wastewater discharges:some parameters were to higher: pH (12,6, Temperature (37,8 °C, C.E (4270 µS/cm, organic matters: COD (1200 mg/l, SO4 (1280 mg/l, PO4(4460 mg/l, NO3 (63,6 mg/l, (Fe (63,34 mg/l, Zn (13,27 mg/l, Pb (4,0 mg/l, Cu (25,34 mg/l, Cd (31,78 mg/l, Cr (5,9 mg/l, Ni (39,5 mg/l. The study concludes that discharge of effluents by the companies; factory and materials from other anthropogenic sources severely pollute the Logone River with heavy metals and other pollutants. We recommended that each industry recycle its wastewater and put in place specific treatment plants, because pollutants to eliminate vary depending on the industry.

  17. Effects of cleaning agents in reducing microbial load on meat display tables at the Bodija municipal abattoir, Ibadan, Nigeria

    2011-06-01

    Full Text Available Meat display tables have been implicated as one of the sources of meat contamination and a critical control point in food processing. Cleaning and disinfection operations are of great importance within the food processing industries for food safety reasons. The effectiveness of four cleaning agents as treatments for the reduction of microbial contamination of meat display tables used by meat sellers at the Bodija municipal abattoir in Ibadan, Oyo state, Nigeria was assessed within April and October, 2009. The treatments include the use of: 1. Pipe-borne water (27oC; 2. Hot water at 85oC; 3. Pipe-borne water and detergent; 4. Combination of pipe-borne water, detergent and sodium hypochlorite. Swab samples were taken from a 1cm2 area on each wooden table surfaces before and after application of each treatment. They were processed and grown on nutrient agar and MacConkey agar to determine the effects of each treatment on total aerobic and coliform counts in the laboratory. The results revealed that all the four treatments had statistically significant difference (P<0.05 in reducing microbial contamination with treatment 4– combination of pipe-borne water, detergent and sodium hypochlorite having the highest percent reduction in total aerobic and coliform counts (63% and 75% respectively. It is recommended that treatments 3 and 4 should be incorporated into the routine activities of meat sellers before the commencement of daily sales and after, because of their greater effect in reducing coliform than treatments 1 and 2, in order to minimize contamination of meat arising from meat display tables.

  18. Real time detection of farm-level swine mycobacteriosis outbreak using time series modeling of the number of condemned intestines in abattoirs.

    Adachi, Yasumoto; Makita, Kohei

    2015-09-01

    Mycobacteriosis in swine is a common zoonosis found in abattoirs during meat inspections, and the veterinary authority is expected to inform the producer for corrective actions when an outbreak is detected. The expected value of the number of condemned carcasses due to mycobacteriosis therefore would be a useful threshold to detect an outbreak, and the present study aims to develop such an expected value through time series modeling. The model was developed using eight years of inspection data (2003 to 2010) obtained at 2 abattoirs of the Higashi-Mokoto Meat Inspection Center, Japan. The resulting model was validated by comparing the predicted time-dependent values for the subsequent 2 years with the actual data for 2 years between 2011 and 2012. For the modeling, at first, periodicities were checked using Fast Fourier Transformation, and the ensemble average profiles for weekly periodicities were calculated. An Auto-Regressive Integrated Moving Average (ARIMA) model was fitted to the residual of the ensemble average on the basis of minimum Akaike's information criterion (AIC). The sum of the ARIMA model and the weekly ensemble average was regarded as the time-dependent expected value. During 2011 and 2012, the number of whole or partial condemned carcasses exceeded the 95% confidence interval of the predicted values 20 times. All of these events were associated with the slaughtering of pigs from three producers with the highest rate of condemnation due to mycobacteriosis. PMID:25913899

  19. Influenza A virus infection of healthy piglets in an abattoir in Brazil: animal-human interface and risk for interspecies transmission

    Ariane Ribeiro Amorim

    2013-08-01

    Full Text Available Asymptomatic influenza virus infections in pigs are frequent and the lack of measures for controlling viral spread facilitates the circulation of different virus strains between pigs. The goal of this study was to demonstrate the circulation of influenza A virus strains among asymptomatic piglets in an abattoir in Brazil and discuss the potential public health impacts. Tracheal samples (n = 330 were collected from asymptomatic animals by a veterinarian that also performed visual lung tissue examinations. No slaughtered animals presented with any noticeable macroscopic signs of influenza infection following examination of lung tissues. Samples were then analysed by reverse transcription-polymerase chain reaction that resulted in the identification of 30 (9% influenza A positive samples. The presence of asymptomatic pig infections suggested that these animals could facilitate virus dissemination and act as a source of infection for the herd, thereby enabling the emergence of influenza outbreaks associated with significant economic losses. Furthermore, the continuous exposure of the farm and abattoir workers to the virus increases the risk for interspecies transmission. Monitoring measures of swine influenza virus infections and vaccination and monitoring of employees for influenza infection should also be considered. In addition regulatory agencies should consider the public health ramifications regarding the potential zoonotic viral transmission between humans and pigs.

    2012-10-01

    From January to February 2008, 468 sheep carcasses (335 male and 133 female) in a Khosroshahr (suburb of Tabriz, East Azerbaijan province, Iran) abattoir were randomly selected for inspection. The aim of the study was to estimate the frequency of caseous lymphadenitis (CLA) in sheep and to compare the results of bacterial cultures and histopathology of suspected cases. The mean age of the population was 2.5 years. One hundred ninety-seven cases containing 153 (77.7%) males and 44 (22.3%) females had prominent enlargement of one of the lymph nodes (i.e., prescapular, prefemoral, inguinal, supramammary, or midiastinal); these were removed with the surrounding tissue for further evaluation. For confirmed diagnosis of CLA, samples were sent for microbiology and pathology analysis. Standard bacteriological culture methods for isolation of Corynebacterium pseudotuberculosis and tissue preparations for histopathological sections were performed. To evaluate the effect of age on the frequency of CLA, animals were categorized in four groups: under 1, 1-2, 2-3, and over 3 years of age. Based on the results, in 59 (12.60%) carcasses C. pseudotuberculosis was isolated, and in 94 (20.08%) of the cases histopathological studies revealed pathognomonic signs (lamellated exudates or onion ring) of CLA. The frequency of CLA based on bacteriological culture was 12.60% and on histopathological study 20.08%. In 37 (18.8%) of the carcasses, both bacteriological and histopathological studies confirmed CLA. The frequency of CLA following microscopic examination (20.08%) presented a more precise diagnosis compared to bacteriological culture (12.60%) and macroscopic evaluation of the lymph nodes (P culture and histopathological study (r = 0.196, P = 0.006). The prescapular lymph node had the highest infection rate with 54 (1.70 ± 0.97) and supramammary lymph node had the lowest with two (0.07 ± 0.41) (P < 0.05). There was an increase in CLA detection with increasing

    Despite extensive utilisation in epidemiological investigations of animal health, to date there has been little consideration of the value of abattoir meat inspection as a pig welfare surveillance tool. This study measured the prevalence of tail-docking, tail biting, carcase condemnations and associated financial losses of the latter (Northern Ireland only) in 36,963 pigs slaughtered in six abattoirs from the Republic of Ireland and Northern Ireland in July and August 2010. Over 99 per cent of inspected pigs had been tail-docked, while 58.1 per cent and 1.03 per cent had detectable and severe tail lesions, respectively. Producer losses resulting from carcase condemnation were estimated to be €0.37 per pig slaughtered. Enhanced capture and utilisation of meat inspection data for use in animal welfare surveillance schemes has the potential to drive improvements in production efficiency and animal welfare. However, significant differences were detected in the prevalence of carcase condemnation conditions between abattoirs and judiciaries (Republic and Northern Ireland). This reflects variation in the criteria and methods of data capture used in meat inspection in different abattoirs. Thus, the meat inspection process needs to be standardised and reformed before it can be reliably utilised in large-scale pig welfare surveillance schemes. PMID:23248113

  2. Mycobacterium bovis identification by a molecular method from post-mortem inspected cattle obtained in abattoirs of Mato Grosso do Sul, Brazil

    Cristina Pires de Araújo

    2005-11-01

    Full Text Available The presence of Mycobacterium bovis in bovine carcasses with lesions suggestive of tuberculosis was evaluated. Seventy-two carcass samples were selected during slaughter inspection procedures in abattoirs in the state of Mato Grosso do Sul, Brazil. Seventeen (23.6% of samples showed colonies suggestive of mycobacteria that were confirmed to be acid-fast bacilli by Ziehl-Neelsen staining. Polymerase chain reaction (PCR using primers specific for M. bovis identified M. bovis in 13 (76.5% isolates. The PCR-restriction enzyme pattern analysis using gene encoding for the 65-kDa protein and two restriction enzymes identified the remaining four isolates that were represented by two M. tuberculosis complex and two nontuberculous mycobacteria. The results are indicative of infection of slaughter cattle by M. bovis and other mycobacteria in the state of Mato Grosso do Sul.

    Data relating to 35,389 inseminations carried out in the first three years after inseminators were trained were collected by postal questionnaire from 94 do-it-yourself (DIY) artificial inseminators in the UK. The mean calving rate from 14,528 inseminations they carried out on 92 farms in the first year after they were trained was 59.4 per cent (range 5 to 92 per cent). In the second year the mean calving rate from 11,515 inseminations by 64 inseminators was 62.3 per cent (range 33 to 88 per cent), and in the third year the mean calving rate from 9346 inseminations by 49 inseminators was 64.6 per cent (range 41 to 92 per cent). There was an increase of 5.2 per cent in the mean calving rate over the three years with an overall mean calving rate of 61.5 per cent. Each trainee carried out an average of 376 inseminations (range 20 to 800) during the three years. Thirteen instructors were responsible for the tuition and the average time the trainees spent in an abattoir with access to live cows was 2.88 days, with a range from none to five days. For the trainees who spent up to three days training in an abattoir there was an increase of 5.9 per cent in the calving rate they achieved in their first year for every day they spent training with access to live cows (P < 0.005), but there were no significant effects on the outcome of their inseminations in their second or third years.

  4. A survey of the causes of cattle organs and/or carcass condemnation, financial losses and magnitude of foetal wastage at an abattoir in Dodoma, Tanzania

    Wilfred Tembo

    2015-02-01

    Full Text Available Slaughterhouses provide a safeguard that prevents the public from consuming meat of poor quality or meat which may be infected with zoonotic diseases. This work reviews a 3-year database of cattle that were slaughtered and inspected between 2010 and 2012 at Dodoma abattoir, Tanzania. In addition, meat inspection was undertaken for 1 month (December 2013. The aim of this study was to establish causes of organ and carcass condemnations and their financial implications as well as the magnitude of slaughter of pregnant cows at Dodoma abattoir. During retrospective study, it was found that a total of 9015 (10.5% lungs, 6276 (7.3% intestines, 5402 (6.3% livers, 3291 (3.8% kidneys and 41 (0.05% carcasses were condemned. Pulmonary emphysema (3.4%, fasciolosis (4.5%, pimply gut (5.7%, kidney congenital cysts (1.9% and hydatidosis (3.1% were major causes of organ condemnations. This large number of condemned edible organs and/or carcasses implies that public health considerations result in deprivation of valuable protein. Occurrence of hydatidosis, cysticercosis, fasciolosis and tuberculosis illustrates the possible public health problem and presence of environmental infections. Of the 794 cows slaughtered in December 2013, 46% were pregnant. Financial loss as a result of organ and/or carcass condemnations was estimated at $9892. Condemnation of organs and/or carcasses and indiscriminate slaughter of pregnant cows represent a significant loss of meat and revenue and a reduction in growth of future herds, which has a negative effect on the livestock industry. This justifies appropriate surveillance and disease control programmes coupled with strict enforcement of legislation governing animal welfare to curb the slaughter of pregnant animals.

  5. The prevalence and characterization of verotoxin-producing Escherichia coli isolated from cattle and pigs in an abattoir in Hong Kong.

    Leung, P H; Yam, W C; Ng, W W; Peiris, J S

    2001-04-01

    The aim of the study was to define the prevalence of verotoxin-producing Escherichia coli (VTEC) in cattle and pigs in a Hong Kong abattoir. Faecal and carcass samples collected from 986 cattle and 487 pigs from an abattoir were tested for verotoxin (VT) by PCR and cytotoxicity assays. VTEC was isolated from 415 and 1-8% of cattle faecal and carcass samples and from 2.1 and 0.2% of porcine faecal and carcass samples, respectively. Amongst 409 VTEC isolates from cattle, 9 were serotype O157:H7 and eaeA+. The most prevalent vt genotype among bovine VTEC was vtl+vt2 (73.8%) and in porcine VTEC was vt2e+ (30%). None of the porcine VTEC isolates and 9.3% of the bovine VTEC isolates was eaeA+. The non-O157 serogroup VTEC isolates carrying eaeA and EHEC-hlyA belonged to serogroups O172, O15, O84, O91, O110 and O121. The local dietary preference for pork or chicken (rather than beef), the low VTEC carriage in pigs, the rarity of additional virulence factors (caeA) in VTEC isolated from cattle may explain the apparently low incidence of human diarrhoeal disease associated with VTEC in Hong Kong hitherto. However, the presence of non-O157 VTEC strains carrying the eacA virulence marker in cattle highlights the fact that sole reliance on sorbitol-MacConkey agar for screening human VTEC isolates may underestimate the human disease burden. The changing dietary habits of the population in Hong Kong reinforce the need for continued vigilance. PMID:11349966

  6. A case study for biogas generation from covered anaerobic ponds treating abattoir wastewater: Investigation of pond performance and potential biogas production

    Highlights: • We report on the performance of a novel covered anaerobic pond system. • Potential biogas production was estimated using BioWin modelling software. • Ponds maintained stable operation; however, accumulation of crust was an issue. • Modelling indicated that biogas yield can be influenced by decomposition efficiency. • Configuration and operation of ponds can also impact potential biogas production. - Abstract: Covered anaerobic ponds offer significant advantages to the red meat processing industry by capturing methane rich gas as a fuel source for bioenergy while reducing greenhouse gas emissions (GHG). This paper presents the results of a novel-designed anaerobic pond system at an Australian abattoir in relation to pond performance and potential biogas production. Key findings in assessing the effectiveness of the system revealed that the covered ponds are capable of efficient wastewater decomposition and biogas production. The primary issue with the covered ponds at the abattoir was the build-up of fat/crust that prevented the accurate measurement of biogas and effective use of the cover. In the absence of field biogas data the novel application of the computer modelling software BioWin® was carried out to simulate chemical oxygen demand (COD) removal rates and subsequent biogas yield. The unique parameter used to fit field data was the fraction of the inlet COD due to a superficial crust which did not follow anaerobic digestion. Field data effluent COD removal rates were matched to simulated rates predicted by BioWin when measured influent COD was reduced to 30%. Biogas modelling results suggest significant variation in the economic benefit of biogas energy, with the quantity of biogas potentially varying tenfold (from 328 m3/d to 3284 m3/d) depending on site factors such as pond efficiency, pond configuration and operational practices

  7. Isolation of Multidrug-Resistant Escherichia coli O157 from Goats in the Somali Region of Ethiopia: A Cross-Sectional, Abattoir-Based Study.

    2015-01-01

    Toxigenic Escherichia coli (E. coli) are an important cause of gastroenteritis in developing countries. In Ethiopia, gastroenteritis due to food-borne disease is a leading cause of death. Yet, there is no surveillance for E. coli O157 and little is known about the carriage of this pathogen in Ethiopia's livestock. This study aimed to assess the prevalence and levels of antimicrobial resistance of E. coli O157 in goat meat, feces, and environmental samples collected at a large abattoir in the Somali region of Ethiopia. The samples were enriched in modified tryptone broth containing novobiocin, and plated onto sorbitol MacConkey agar. Isolates were confirmed using indole test and latex agglutination. Antimicrobial susceptibility testing was conducted using the disk diffusion method. A total of 235 samples, including 93 goat carcass swabs, 93 cecal contents, 14 water, 20 hand, and 15 knife swabs were collected. Overall, six (2.5%) samples were contaminated with E. coli O157 of which two (2.1%) were isolated from cecal contents, three (3.2%) from carcass swabs, and one (7.1%) from water. All isolates were resistant to at least two of the 18 antimicrobials tested. Two isolates (33.3%) were resistant to more than five antimicrobials. Abattoir facilities and slaughter techniques were conducive to carcass contamination. This study highlights how poor hygiene and slaughter practice can result in contaminated meat, which is especially risky in Ethiopia because of the common practice of eating raw meat. We detect multi-resistance to drugs not used in goats, suggesting that drugs used to treat human infections may be the originators of antimicrobial resistance in livestock in this ecosystem. The isolation of multidrug-resistant E. coli O157 from goats from a remote pastoralist system highlights the need for global action on regulating and monitoring antimicrobial use in both human and animal populations.

    Full Text Available In this study, the presence of extended spectrum beta lactamase (ESBL producing organisms in abattoirs, a non-hospital community was investigated. The presence of ESBL-producing phenotypes was confirmed by the Double Disc Synergy Test (DDST. Out of the 99 isolates screened for ESBL, 28 (28.3% were confirmed positive. The positive isolates were characterised by using Matrix-Assisted Laser Desorption/Ionization Time of flight Mass Spectrometry. 50% of the isolates were Pseudomonas spp., the rest were different species of Acinetobacter, Stenotrophomonas and Achromobacter. Pseudomonas monteilli and Pseudomonas putida were the most occurring in the intestine. The entire positive ESBL producers were subjected to plasmid curing to ascertain the location of the resistant marker. The result of the plasmid curing indicated that the resistant genes were chromosomally borne. The findings have therefore established the presence of ESBL producing organisms in the gut of animals from abattoirs and the table were the meat are sold, and its rate of occurrence is comparable to hospital ICUs. Abattoir communities could probably be a source of human infection with ESBL expressing pathogens and possible transfer to non-ESBL producers.

  10. Hot-water spraying is a sensitive test for signs of life before dressing and scalding in pig abattoirs with carbon dioxide (CO2) stunning.

    2016-02-01

    This study investigated the benefits of hot-water spraying (HWS) as a diagnostic test to verify the absence of signs of life (SOL) before scalding in pigs slaughtered with carbon dioxide (CO2) stunning. A total of 37 108 finishing pigs from five German abattoirs (A to E) operating at 55 to 571 pigs per hour were assessed. Suspended pigs were sprayed onto the muzzle, head and front legs (143 to 258 s post sticking for 4 to 10 s, 57°C to 72°C). Any active movements during HWS were rated as positive test outcomes. In comparison, SOL were considered to be absent if a subsequent manual examination was negative and no active movements were observed following HWS. The incidence of pigs with activity during hot-water spraying (PWA) was restricted to two abattoirs (B: 0.25%; D: 0.02%; A, C, E: 0.00%). PWA showed movements of facial muscles (88%), mouth opening (78%), righting reflex (63%), isolated leg movements (35%) and vocalization (4%). The manual examination was positive in 71% of PWA (corneal/dazzle reflex: 67%/53%, nasal septum pinch: 33%), whereas all inactive pigs tested negative (P99.9% in either case. Any positive manual findings as well as any respiratory activity were instantly terminated using a penetrating captive bolt. Active movements triggered by the shot were shown to be an indicator for SOL (Pactivity (controls). Results for different categories of SM in PWA v. controls were as follows: 100% v. 2.6% for mouth opening, 16.0% v. 0.1% for righting reflex and 22.0% v. 0.9% for isolated leg movements (all P<0.001). First mouth opening after sticking was observed later in PWA (28±24 v. 10±7 s), but mouth openings were observed for a longer period of time (141±44 v. 27±25 s) (both P<0.001). PWA with shorter mouth-opening intervals showed higher movement intensities during HWS and more positive manual findings (P<0.05). We conclude that HWS is a promising test for SOL. SM and sustained mouth opening in particular are indicators for compromised animal

    The prevalence of rumen fluke, the incidence of clinical paramphistomosis and the trematode's species identity were studied in cattle and sheep in the Republic of Ireland using passive veterinary surveillance (faecal examination and necropsy results; 2010-2013) and abattoir data. Based on faecal examination, the prevalence of rumen fluke was higher in cattle than in sheep. Rumen fluke prevalence in cattle and sheep fluctuated over the year and in most years (2011-2013), prevalence was higher in winter (December-February) than in summer (June-August). For 3 of 4 years studied, there was no correlation between monthly prevalence of rumen fluke and prevalence of liver fluke as estimated by faecal examination. At sample level, joint occurrence of rumen fluke and liver fluke was 1.1-2.0 times more common than would be expected under the assumption of independence. Based on necropsy data, a spike in deaths attributed to paramphistomosis was observed in 2012, when rainfall was unusually high. This spike in mortality was not accompanied by a spike in faecal prevalence, emphasizing that the incidence of disease, which is due to high burdens of juvenile rumen fluke in the gut, is not correlated with prevalence of infection, which is measured by faecal examination and reflects presence of adult fluke in the rumen. At slaughter, 52% of 518 cattle from 101 herds were positive for rumen fluke, compared to 14% of 158 sheep. Prevalence in cattle was higher than reported in most studies from mainland Europe and varied by animal category, age, sex, abattoir visit and location (county) of farm from which the animal was submitted for slaughter, but in multivariate analysis, only sampling month and county were significantly associated with detection of rumen fluke. The identity of rumen fluke in cattle and sheep was confirmed as Calicophoron daubneyi. Although C. daubneyi is thought to share an intermediate host snail with Fasciola hepatica, the differences in prevalence between host

    Full Text Available Salmonellae are ubiquitous, found in animals, humans, and the environment, a condition which facilitates transmission and cross contamination. Salmonella enterica serotypes exert huge health and economic impacts due to their virulence or carriage of antibiotic resistance traits. To address this significant issues with regard to public health, availability of adequate information on the prevalence and antibiotic resistance patterns of Salmonella, and establishment of adequate measures to control contamination and infection are needed. A cross-sectional study was conducted to assess the level of Salmonella infection in slaughtered bovines and ovines at Addis Ababa abattoir. Samples were collected randomly and processed for identification and antimicrobial susceptibility testing of Salmonella spp. From 280 animals examined, 13 (4.64% (8 bovines and 5 ovines were positive, with most samples (12/13, 92% comprising Salmonella Dublin. Very high level of resistance to some antibiotics used in human medicine was detected. Most isolates were susceptible to gentamycin and amikacin. Nine (69% of all isolates were resistant to multiple antibiotics. Serotyping revealed 12 of 13 isolates to be of the Dublin serotype with 9,12:g,p:- antigenic formula. This study emphasizes the importance of improving the evisceration practice during slaughtering and restricting the use of antibiotics in farm animals.

    Broiler mortality during transport to abattoirs (dead-on-arrival/DOA) evokes concern due to compromised animal welfare and associated economic losses. The general aim of this study was to characterize pathological lesions associated with mortality in broilers close to slaughter. The specific aim was to investigate whether disease at the end of the growth period may be a predisposing factor for DOA by describing and comparing the pathological findings in broilers dead-on-farm (DOF) in the final days of the production cycle and in broilers DOA from the same flocks. Gross post-mortem examinations were performed on 607 broilers from 32 flocks, either DOF (371) or DOA (236). In DOF broilers, the most common pathological lesions were lung congestion (37.7%), endocarditis (29.4%), and ascites (24.0%), whereas the most common findings in broilers DOA were lung congestion (57.2%) and trauma (24.6%). Lung congestion was more prevalent among DOA broilers compared to DOF broilers (P-value of > 0.001). A possible cause behind the pathological finding lung congestion is sudden death syndrome (SDS). The study indicates that steps in the transportation process per se cause the majority of pathological lesions such as lung congestion and trauma that may have led to the mortalities registered. Pre-existing diseases such as ascites and osteomyelitis may also predispose for DOA. Thus, factors relating to on-farm health, catching, and transportation are all areas of future investigation in order to reduce transport mortalities and to enhance welfare in broilers.

    Water used in a modern poultry processing line was tested from October 2005 to June 2006 to determine the level of bacteria in an abattoir in Germany. A total of 420 water samples were taken from 14 processing sites (PSs), at 10 times, and from three different hours of the working shift at three sampling hours (SHs) at 5:00 a.m. (SH 1), 9:00 a.m. (SH 2) and 12:00 a.m. (SH 3). Each sample was assessed for the aerobic plate count (APC) and the prevalence of Salmonella, Campylobacter, Listeria and Yersinia over 30 sampling weeks. The APC numbers of each PS from three SHs were compared, and the prevalence of Salmonella, Campylobacter, Listeria and Yersinia from each PS of three SHs was determined as well as change from the initial PS to the end of the processing line. A total of 46 water samples were positive for Salmonella, 120 positive for Campylobacter and 4 positive for Listeria. None of the water samples was found to be positive for Yersinia. During the course of the day, the APC increased. Salmonella was mostly found during SH 1 (5 a.m.) in water from all PSs. A high number of Campylobacter were observed at SH 2 (9 a.m.) and SH 3 (12 a.m.) from all PSs. The results show that water, which is still used in substantial amounts in present poultry processing technology, can serve as a carrier for Salmonella and Campylobacter. The findings indicate that birds might progressively contaminate the equipment and become contaminated via the same equipment, that water at every processing position of the line constitutes a risk and that more attention should be paid to effective water management in the processing plan.

    2010-12-01

    In nine districts in the north of Khorasan province, in north-eastern Iran, a 5-year retrospective study was carried out to determine the prevalences, in livestock slaughtered in abattoirs, of the parasitic infections responsible for the condemnation of the animals' carcasses and viscera (and the economic importance of such infections in terms of lost meat and offal). Between 20 March 2005 and 19 March 2010, 436,620 animals (45,360 cattle, 275,439 sheep, 115,674 goats and 147 camels) were slaughtered in the study area and the livers of 30,207 (6.9%), the lungs of 23,259 (5.3%) and the carcasses of 1072 (0.2%) of these animals were condemned. Almost all (92.4%) of the condemned livers, most (68.9%) of the condemned lungs but only 10.8% of the condemned carcasses were rejected because of parasitic infection. The parasitic lesions observed in the condemned livers were attributed to Echinococcus granulosus, Fasciola hepatica and/or Dicrocoelium dendriticum (cattle, sheep and goats) or entirely to E. granulosus (camels). All the parasitic lesions observed in the condemned lungs (which also came from cattle, sheep, goats and camels) were attributed to E. granulosus. Sarcocystis cysts and/or Taenia cysticerci were found in ovine muscle while only Taenia cysticerci were detected in bovine muscle (no parasitic lesions were observed in the muscles of the goats and camels). Parasites were responsible for 80.8% of the condemned organs or carcasses, and the value of the food lost because of parasite-related condemnation (based on market prices in 2010) was estimated to be U.S.$421,826 (U.S.$47,980 for cattle, U.S.$316,344.0 for sheep, U.S.$57,372 for goats and U.S.$130 for camels). The parasites contributing most to the condemnation of otherwise marketable organs and muscles were E. granulosus (52.2%) and D. dendriticum flukes (29.5%). These parasites clearly remain too common and cause considerable economic loss in Khorasan and, presumably, other areas of Iran. PMID:21144183

    Full Text Available This work aimed to assess the effects of preslaughter lairage time on the welfare and mortality of broilers transported in different farm-abattoir distances. It was evaluated 215 poultry transport trucks from a commercial poultry slaughterhouse from 2006 to 2007. Data were obtained from the holding area acclimatized through fans and water misting in the mornings, afternoons and at night. The thermal variables (temperature and relative humidity, distance, lairage time and density of birds per cage were considered in the analysis. The effects of distance and lairage time were important in the variation of rectal temperature of the animals and on the number of dead animals per truck. Two models were developed (mean and dispersion, for each response variable in function of the interaction between lairage time and distance. As the lairage time in the holding area increased, the rectal temperature of the birds was reduced for all the studied distances. In farm-abattoir distances higher than 25 km, mortality was low when lairage time was lower than 1 hour. However, for distances below 25 km, in the same time interval, the number of dead birds was two-fold higher than in the first situation. The adjustment of lairage time has to be done accordingly to the distance provided that the lairage environment is correctly climatized.Avaliou-se o efeito do tempo de espera pré-abate no bem-estar e na mortalidade de frangos de corte transportados em diferentes distâncias granjas-abatedouro.

    Mycoplasma hyopneumoniae, the causative agent of porcine enzootic pneumonia, is present in swine herds worldwide. However, there is little information on strains infecting herds in Canada. A total of 160 swine lungs with lesions suggestive of enzootic pneumonia originating from 48 different farms were recovered from two slaughterhouses and submitted for gross pathology. The pneumonic lesion scores ranged from 2% to 84%. Eighty nine percent of the lungs (143/160) were positive for M. hyopneumoniae by real-time PCR whereas 10% (16/160) and 8.8% (14/160) were positive by PCR for M. hyorhinis and M. flocculare, respectively. By culture, only 6% of the samples were positive for M. hyopneumoniae (10/160). Among the selected M. hyopneumoniae-positive lungs (n=25), 9 lungs were co-infected with M. hyorhinis, 9 lungs with PCV2, 2 lungs with PRRSV, 12 lungs with S. suis and 10 lungs with P. multocida. MLVA and PCR-RFLP clustering of M. hyopneumoniae revealed that analyzed strains were distributed among three and five clusters respectively, regardless of severity of lesions, indicating that no cluster is associated with virulence. However, strains missing a specific MLVA locus showed significantly less severe lesions and lower numbers of bacteria. MLVA and PCR-RFLP analyses also showed a high diversity among field isolates of M. hyopneumoniae with a greater homogeneity within the same herd. Almost half of the field isolates presented less than 55% homology with selected vaccine and reference strains. PMID:24345410

    Full Text Available The presence of Aeromonas spp. in food has been demonstrated. They are often introduced from water, which is the natural habitat of many species and is thought to be the main source of contamination. The occurrence of Aeromonas spp. was investigated in 70 water samples of a bovine abattoir. Aeromonas spp. were present in 21.4% of water samples. A. hydrophila was isolated from 11.4% of supplying water samples and from 25.7% of the water drained from carcasses, whereas A. sobria was sole isolated from 5.7% of supplying water samples. Although greater number of positive samples were from water drained from carcasses, only A. hydrophila isolates were present. This suggests that the supplying water is the source of contamination. The antibiotic susceptibility testing revealed all strains were resistant to b-lactam antibiotics. However, the susceptibility to other antimicrobials was variable, being A. hydrophila more resistant than A. sobria strains. The investigation for virulence factors revealed positive reactions of hemolysis and hemagglutination. The results indicate that Aeromonas spp. are present in the supplying water system. These microorganisms may be a potential contaminant of carcasses and widespread in derived food.A presença de bactérias do gênero Aeromonas nos alimentos tem sido demonstrada. Normalmente destacam-se os alimentos que durante sua industrialização entraram em contato com a água, a qual é tida como habitat natural das diversas espécies e principal fonte de contaminação.

  7. Survey of porcine parvovirus infection in swine fetuses and their dams at a Minnesota abattoir

    Thacker, B.J.; Leman, A.D.; Hurtgen, J.P.; Sauber, T.E.; Joo, H.S.

    1981-05-01

    Reproductive tracts were recovered from 209 sow and 32 gilt carcasses at slaughter; animals had been pregnant not less than 27 days. Of 241 litters examined, 28 (11.6%) contained one or more porcine parvovirus (PPV)-infected fetuses, as determined by immunofluorescent microscopy. The frequencies in sow and gilt litters were 12.0% and 9.4%, respectively. The PPV antigen was detected in 219 of 334 (65.6%) dead or mummified fetuses and in 12 of 2,172 (0.5%) live fetuses examined. The 18 litters which contained only dead or mummified fetuses were infected with PPV. As the percentage of litter mummification increased, the likelihood of finding PPV increased. The PPV antibody was detected in ovarian follicular fluids of 94.3% of the sows and 78.1% of the gilts. These findings indicate that PPV is highly associated with fetal mummification and that some pregnant gilts and sows are susceptible to infection.

    Full Text Available Examinations were carried out during the period from January 2006 until March 2007 on a total of 449 samples of the cecum of broilers and the cecum and the colon of pigs. These samples included 251 samples originating from broilers and 198 samples of pig cecums and colons. All the listed samples were obtained by scraping the surface of these parts of the digestive system of broilers and pigs. At the site of sampling, the diluted material was sown on a medium (Karmali agar, in order to get individual colonies. After sowing, the bases were placed in anaerobic jars in which microaerophilic conditions were achieved using Campy Pak, BBL bags. On arrival at the laboratory, the jars containing the sown bases were placed in a thermostat, at a temperature of 42oC for 48 hours for the purpose of incubation. Following incubation, the grown colonies were examined macroscopically, and then microscopic preparations were made from them, which were stained with 2% carbol fuchsin after drying and fixation. Those isolates which were in the form of a comma, the letter S, or gull's wings in the microscopic preparations were considered Campylobacter species (Figures 1 and 2. The isolated thermophilic campylobacteria were identified using conventional and commercial biochemical tests API Campy, manufactured by Bio Mérieux, France. With the application of these microbiological methods, thermophilic Campylobacter species were isolated from 203 (80.88% of the 251 samples of broiler cecums. Furthermore, thermophilic campylobacteria were isolated from 153 (77.27% of the 198 samples from the cecum and colon of pigs taken within these investigations. The obtained results indicate that there is a somewhat greater prevalence of these bacteria among the broilers. However, such a high percentage of both broilers and pigs colonized by thermophilic Campylobacter species could pose a serious problem, in particular when it is known that infections of humans caused by the consumption of insufficiently thermally processed meat of broilers or pigs are not infrequent.

  10. Diagnostic accuracy of porcine acute phase proteins in meat juice for detecting disease at abattoir.

    Gutiérrez, A M; Martínez-Subiela, S; Cerón, J J

    2015-07-01

    The aim of this work was to evaluate whether acute phase protein (APP) determinations could assist Official Veterinarians carrying out work in slaughterhouses. To test this hypothesis, the diagnostic accuracy of APP determinations in meat juice of pigs was analysed to differentiate between healthy and diseased pigs. One hundred and one pigs of two different origins were classified into two groups according to their health status (healthy and diseased pigs), which was determined by a veterinary clinical examination on the farm. To assess the pigs' immune status, against the main porcine diseases, serological analyses were monitored. A general idea of the degree of disease coverage was analysed by examining organ lesions postmortem. Haptoglobin (Hp) and C reactive protein (CRP) were measured in meat juice samples. 72.13 per cent of pigs appeared to be seropositive for the porcine respiratory and reproductive syndrome virus, and almost 86.2 per cent of them had concomitant infections with other pathogens, such as Porcine circovirus type 2 or Swine influenza virus. Median Hp and CRP concentrations were significantly higher in diseased animals at different stages of the production chain, when compared with levels found in healthy finishing pigs (P<0.0001). Receiver operating characteristic analysis showed the highest sensitivity-specificity pairs, nearly 80-90 per cent, at cut-off levels of 83 and 10 µg/ml for Hp and CRP determinations, respectively, with high AUCs 0.9. This cut-off could be useful for veterinary inspections at the time of slaughter, to differentiate between the carcase of a healthy animal and the carcase of an animal suffering from a systemic disease, which should be completely condemned.

    2010-01-01

    The study hypothesis was that pre-slaughter handling is not conducted in such a way that pigs can be considered humanely slaughtered, nor is it conducive to promoting those properties of fresh meat that could enhance pork quality. The 1st phase of the investigation was aimed at confirming the present compliance level within the prescribed norms. To this end the importance of stunning induction requirements for effective electrical stunning, the welfare implications relating to the pre-slaught...

  13. Biological phosphorus removal from abattoir wastewater at very short sludge ages mediated by novel PAO clade Comamonadaceae.

    2015-02-01

    Recent increases in global phosphorus costs, together with the need to remove phosphorus from wastewater to comply with water discharge regulations, make phosphorus recovery from wastewater economically and environmentally attractive. Biological phosphorus (Bio-P) removal process can effectively capture the phosphorus from wastewater and concentrate it in a form that is easily amendable for recovery in contrast to traditional (chemical) phosphorus removal processes. However, Bio-P removal processes have historically been operated at medium to long solids retention times (SRTs, 10-20 days typically), which inherently increases the energy consumption while reducing the recoverable carbon fraction and hence makes it incompatible with the drive towards energy self-sufficient wastewater treatment plants. In this study, a novel high-rate Bio-P removal process has been developed as an energy efficient alternative for phosphorus removal from wastewater through operation at an SRT of less than 4 days. The process was most effective at an SRT of 2-2.5 days, achieving >90% phosphate removal. Further reducing the SRT to 1.7 days resulted in a loss of Bio-P activity. 16S pyrotag sequencing showed the community changed considerably with changes in the SRT, but that Comamonadaceae was consistently abundant when the Bio-P activity was evident. FISH analysis combined with DAPI staining confirmed that bacterial cells of Comamonadaceae arranged in tetrads contained polyphosphate, identifying them as the key polyphosphate accumulating organisms at these low SRT conditions. Overall, this paper demonstrates a novel, high-rate phosphorus removal process that can be effectively integrated with short SRT, energy-efficient carbon removal and recovery processes.

    2015-10-01

    Full Text Available Introduction & Objective: 130 heteroxenous species of sarcosytis with different life cycle and pathogenesis have been recognized. The pathogenic species for humans are S. hominis from cattle and S. suihominis from pig that humans are definitive and cattle and pig are intermedi-ate hosts. Some species of Sarcocystis can cause important economic loss and disease in livestock, and health issues in humans. The aim of this study was to determine the prevalence of Sarcocystis infection in slaughtered Cattle and sheep in Hamadan, west of Iran. Materials & Methods: In this cross sectional descriptive study a total of 324 cattle and 334 sheep carcasses were examined using naked eye inspection for macroscopic Sarcocysts, and digestion method, for microscopic types of parasite. Muscles from thigh, heart, tongue, esophagus, diaphragm and costal muscles were examined. All carcasses examined by naked eyes and tissues were minced and poured in digestion medium separately and sediment was examined microscopically. Results: The prevalence of microscopic Sarcocystis in cattle was detected in 100% and there was no macroscopic cyst in examined carcasses. However, the prevalence of microscopic Sarcocystis in the sheep was also 100% and the sarcocysts were found in the 48.34 % of esophagus and 29.49% of diaphragm muscles by naked eyes inspection. Conclusion: The digestion is found the most sensitive method for diagnosis of Sarcocystis. Al-though 100% of muscles were found infected but the majority of the cysts in the sheep and all in the cattle were as microcysts. That means, the meat should be cooked sufficiently irrespec-tive of meat inspection results. (Sci J Hamadan Univ Med Sci 2015; 22 (3: 210-216

    Full Text Available The purpose of this study was to explore the audits, quality assurance (QA programmes and legal frameworks used in selected abattoirs in Zimbabwe and slaughterhouse workers’ perceptions on their effectiveness. Data on slaughterhouse workers was gathered through a self-completed questionnaire and additional information was obtained from slaughterhouse and government records. External auditing was conducted mainly by the Department of Veterinary Public Health with little contribution from third parties. Internal auditing was restricted to export abattoirs. The checklist used on auditing lacked objective assessment criteria and respondents cited several faults in the current audit system. Most respondents (>50.0% knew the purposes and benefits of audit and QA inspections. All export abattoirs had QA programmes such as hazard analysis critical control point and ISO 9001 (a standard used to certify businesses’ quality management systems but their implementation varied from minimal to nil. The main regulatory defect observed was lack of requirements for a QA programme. Audit and quality assurance communications to the selected abattoirs revealed a variety of non-compliances with most respondents revealing that corrective actions to audit (84.3% and quality assurance (92.3% shortfalls were not done. A high percentage of respondents indicated that training on quality (76.8% and regulations (69.8% was critical. Thus, it is imperative that these abattoirs develop a food safety management system comprising of QA programmes, a microbial assessment scheme, regulatory compliance, standard operating procedures, internal and external auditing and training of workers.

This research was carried out between January 2005 and June 2006. Swab samples were collected from abattoirs cutting tables with sterile swab sticks and immediately transferred and cultured in the laboratory on a selective medium Sabouraud Dextrose Agar (SDA. The disinfectants’ concentrations were prepared at 10%, 20%, 40%, and 70%, in triplicates and the mean values calculated. 0.5 Mc Farland turbidity method of standardization and Agar diffusion method were used for disinfectants testing of the isolates. Statistical analysis of the data showed no significant difference in the effectiveness of these disinfectants at (p<0.05. In conclusion, this study has shown that savlon and dettol were the most potent antimicrobial agents at 10% concentration on Candida albicans isolates when compared with purit and jik in this study, hence they are good sanitizing agents to be applied on the abattoirs cutting tables, before meat products can be displayed for sale.

    2014-01-01

    Veterinary surgeons working on farms and food-processing establishments play a fundamental role in safeguarding both public health and the welfare of animals under their care. An essential part of veterinary public health (VPH) undergraduate training in the UK involves students undertaking placements within abattoirs, a practice that remains vital to the educational experience of future veterinary professionals. However, several issues have adversely affected the ability of students to gain such extramural placements. For this reason, the Virtual Slaughterhouse Simulator (VSS) was developed to strengthen and enhance undergraduate VPH teaching at the Royal (Dick) School of Veterinary Studies, enabling students to explore a realistic abattoir work environment with embedded educational activities. The aim of this research project was to evaluate the VSS as a teaching and learning tool for training and educating veterinary students. Ninety-eight final-year veterinary students engaged with the prototype VSS, followed by assessment of their knowledge and behavior when faced with a "real-life" abattoir situation. Further evaluation of their experiences with the VSS was carried out using questionnaires and focus groups. The results of this investigation show that there is the potential for the VSS to enhance the student learning experience in basic abattoir procedures. This innovative tool provides a visually based learning resource that can support traditional lectures and practical classes and can also be used to stimulate interactive problem-solving activities embedded in the relevant context.

    Velarde, A; Gispert, M; Faucitano, L; Manteca, X; Diestre, A

    2000-07-01

    Two commercial pig abattoirs (A and B) equipped with a head-only and head-to-chest electrical stunning systems, and two (C and D) equipped with compact carbon dioxide (CO(2)) stunning systems, were visited during 3 days to evaluate the effects of the stunning system on meat quality and haemorrhages. Meat quality was evaluated by measuring muscle electrical conductivity (PQM) and colour (Minolta Chromameter) at 2 and 7 h post mortem (abattoirs A and C, and B and D, respectively). PQM and colour were measured in 2486 and 2321 loins respectively. Also ultimate pH (pHu) was measured in 2395 loins at 24 h post mortem. Haemorrhages were evaluated by recording the incidence of petechiae, ecchymosis and haematomas, bone fractures were also recorded. A total of 1980 shoulders, 3943 loins, and 5438 hams were inspected. In the abattoirs equipped with the electrical stunning systems, a higher (P6) was found compared with the abattoirs equipped with CO(2) stunning. Likewise, the loins from electrically stunned pigs were paler than those from CO(2) stunned pigs (PElectrical stunning increased the incidence of petechiae in the loin and the ham (Pelectrical stunning. However, petechiae are not of great importance because they can be removed from the affected commercial cuts. PMID:22061288

    Full Text Available Antimicrobial resistant Salmonella are among the leading causes of foodborne infections. Our aim was to determine Salmonella contamination during cattle slaughter in South African rural abattoirs (n = 23 and environmental samples. Furthermore, antimicrobial resistance patterns of the Salmonella isolates were determined. Samples of cattle faeces (n = 400, carcass sponges (n = 100, intestinal contents (n = 62, hides (n = 67, and water from the abattoirs (n = 75 were investigated for Salmonella species using microbiological techniques and species-specific polymerase chain reaction targeting the invA gene. In total 92 Salmonella species isolates were recovered. The Salmonella mean frequency of occurrence on hides, carcasses, and intestinal contents was 35.37% (n = 81. Eleven faecal samples (2.75% tested positive for Salmonella. The predominant serovar was Salmonella Enteritidis. Diverse serovars that were identified on carcasses were not necessarily found on the hides and intestinal contents. The inconsistent occurrence of the diverse Salmonella serovars on hides, carcasses, and intestinal contents implies that in addition to carriage on hides and in intestinal contents, other external factors also play an important role regarding carcass contamination. The 92 Salmonella were serotyped and tested for susceptibility towards the following antimicrobials: ampicillin, cefotaxime, enrofloxacin, kanamycin, and oxytetracycline using the disk diffusion method. Most Salmonella (n = 66; 71.7% isolates were resistant to at least one antimicrobial with highest resistance observed towards oxytetracycline (51.90%, which highlights the need for strict hygiene during slaughter and prudent antimicrobial use during animal production. In conclusion, cattle slaughtered in South African rural abattoirs harbour diverse Salmonella serovars that are resistant to antimicrobials, which could be a public health risk. The findings should assist policymakers with improving

  11. Saltelli Global Sensitivity Analysis and Simulation Modelling to Identify Intervention Strategies to Reduce the Prevalence of Escherichia coli O157 Contaminated Beef Carcasses.

    Victoria J Brookes

    Full Text Available Strains of Shiga-toxin producing Escherichia coli O157 (STEC O157 are important foodborne pathogens in humans, and outbreaks of illness have been associated with consumption of undercooked beef. Here, we determine the most effective intervention strategies to reduce the prevalence of STEC O157 contaminated beef carcasses using a modelling approach.A computational model simulated events and processes in the beef harvest chain. Information from empirical studies was used to parameterise the model. Variance-based global sensitivity analysis (GSA using the Saltelli method identified variables with the greatest influence on the prevalence of STEC O157 contaminated carcasses. Following a baseline scenario (no interventions, a series of simulations systematically introduced and tested interventions based on influential variables identified by repeated Saltelli GSA, to determine the most effective intervention strategy.Transfer of STEC O157 from hide or gastro-intestinal tract to carcass (improved abattoir hygiene had the greatest influence on the prevalence of contaminated carcases. Due to interactions between inputs (identified by Saltelli GSA, combinations of interventions based on improved abattoir hygiene achieved a greater reduction in maximum prevalence than would be expected from an additive effect of single interventions. The most effective combination was improved abattoir hygiene with vaccination, which achieved a greater than ten-fold decrease in maximum prevalence compared to the baseline scenario.Study results suggest that effective interventions to reduce the prevalence of STEC O157 contaminated carcasses should initially be based on improved abattoir hygiene. However, the effect of improved abattoir hygiene on the distribution of STEC O157 concentration on carcasses is an important information gap-further empirical research is required to determine whether reduced prevalence of contaminated carcasses is likely to result in reduced

  12. RELIGIOUS SLAUGHTER: EXAMPLES OF PRACTICES IN ITALY

    B. Catanese

    2011-01-01

    Full Text Available The present study aimed at identifying the procedures for current methods of religious slaughter. It consisted of spot visits in abattoirs carried out from October 2008 to March 2009 in Italy. The species covered were cattle, sheep and poultry. During this period, five abattoirs in three different Italian regions were assessed. All the animals were slaughtered without stunning. A reliable protocol was developed to record each animal during slaughter, to get 329 minutes and 28 seconds of video. 313 animals were observed by video image analysis for both halal slaughter and shechita. Observed parameters are discussed in the light of animal welfare. Remarks on restraining methods as well as post-cut clinical indicators of consciousness are considered.

  13. Reproductive wastage through slaughtering of pregnant ewe and goat in Quagadougou, Burkina Faso

    Data collected from 3190 small ruminants (2408 ewe and 782 goats) have been examined after slaughtering, from January to June 2005 in Ouagadougou refrigerated abattoir. 26.70% of sheep and 34.91% of goats were more in advanced gravidity with losses estimated to 0.33 lamb and 0.44 kid per slaughtered sheep and goat. Animals slaughtered during the second half of their gravidity (2-5 months) represented 53.19% of sheep and 58.24% of goats although at this period, the foetus becomes palpable and detectable. This survey attracts the attention on the losses due to the slaughtering of pregnant females, as the deficit in animal proteins doesn't stop worsening. Urgent measures must be considered to decrease the extent of these losses and it is recommended to detect pregnancy females in abattoir and breeders must be trained to simple methods of gestation detection

  14. The effect of the sticking method on the welfare of slaughter pigs.

    Anil, M H; Whittington, P E; McKinstry, J L

    2000-07-01

    A project was undertaken to investigate the causes of inadequate sticking encountered during a survey of pig abattoirs. The results of the investigation identified the length of the sticking (exsanguination) wound as a major contributor to the problem. Experimental abattoir trials conducted on slaughter pigs comparing two sticking lengths indicated that the rate of bleed out was delayed with short sticking wounds. In addition, information about the identity of blood vessels severed following sticking was obtained. The results indicate that following head-only electrical stunning, a relatively long sticking wound should provide better welfare in slaughter pigs. The study has also highlighted the health and safety problems for the operatives as well as the welfare concerns associated with manual application of electrical stunning. PMID:22061289

  15. A prevalence study of Salmonella spp., Yersinia spp., Toxoplasma gondii and porcine reproductive and respiratory syndrome virus in UK pigs at slaughter.

    Powell, L F; Cheney, T E A; Williamson, S; Guy, E; Smith, R P; Davies, R H

    2016-05-01

    An abattoir-based study was undertaken between January and May 2013 to estimate the prevalence of Salmonella spp. and Yersinia spp. carriage and seroprevalence of antibodies to Toxoplasma gondii and porcine reproductive and respiratory syndrome virus (PRRSv) in UK pigs at slaughter. In total, 626 pigs were sampled at 14 abattoirs that together process 80% of the annual UK pig slaughter throughput. Sampling was weighted by abattoir throughput and sampling dates and pig carcasses were randomly selected. Rectal swabs, blood samples, carcass swabs and the whole caecum, tonsils, heart and tongue were collected. Salmonella spp. was isolated from 30·5% [95% confidence interval (CI) 26·5-34·6] of caecal content samples but only 9·6% (95% CI 7·3-11·9) of carcass swabs, which was significantly lower than in a UK survey in 2006-2007. S. Typhimurium and S. 4,[5],12:i:- were the most commonly isolated serovars, followed by S. Derby and S. Bovismorbificans. The prevalence of Yersinia enterocolitica carriage in tonsils was 28·7% (95% CI 24·8-32·7) whereas carcass contamination was much lower at 1·8% (95% CI 0·7-2·8). The seroprevalence of antibodies to Toxoplasma gondii and PRRSv was 7·4% (95% CI 5·3-9·5) and 58·3% (95% CI 53·1-63·4), respectively. This study provides a comparison to previous abattoir-based prevalence surveys for Salmonella and Yersinia, and the first UK-wide seroprevalence estimates for antibodies to Toxoplasma and PRRSv in pigs at slaughter.

  1. Knife force differences when cutting meat at different temperatures

    Hägg, Göran M; Vogel, Kjerstin; Karltun, Johan; McGorry, Raymond

    2012-01-01

    Introduction Meat cutters in abattoirs is a group with high risks for musculoskeletal disorders. A major reason for this is that they exert high hand forces over a great part of the day when cutting meat. Though meat is refrigerated due to hygienic demands, meat temperature can vary. Meat cutters have claimed that knife forces increase with lower temperatures. This study was performed to find out what effects the meat temperature has on cutting forces. In addition, the same issue was addresse...

    2013-08-01

    Full Text Available The accumulation of Polycyclic Aromatic Hydrocarbons (PAH in sediment and the flesh/carapace of the edible swimming crab Callinectes pallidus from Azuabie creek in the upper Bonny Estuary, Niger Delta and Nigeria were studied. Sediment and crab samples were collected from three sampling stations along the Azuabie creek in July (rainy season and November (dry season 2007. These stations were selected to reflect point of abattoir waste input (which includes ash from tyre used for roasting meat into the creek as well as locations upstream and downstream of the point. Seasonal and spatial variations were observed in the concentrations of PAH. Significant differences in PAH (p<0.01 were observed between rainy season and dry season samples. The major classes of PAH found in sediment and Callinectes pallidus Callinectes pallidus C. pallidus Naphthalene, Benzo (a pyrene, Benzo (a anthracene and Phenanthrene which are known to be carcinogenic. The PAHs were higher during the rainy season probably due to run-off of tyre ash from the nearby abattoir. The observations made in this study suggest thatC. pallidus from the Azuabie creek might not be safe for human consumption because of the levels of PAHs found in the flesh of samples mostly in the rainy season. The abattoir appears to impact the creek because significantly higher levels of PAHs were recorded at the proximate sampling station.

  20. Effects of the stunning procedure and the halothane genotype on meat quality and incidence of haemorrhages in pigs.

    Velarde, A; Gispert, M; Faucitano, L; Alonso, P; Manteca, X; Diestre, A

    2001-07-01

    A total of 313 pigs (127 halothane-free, NN, and 186 heterozygous halothane, Nn) were slaughtered in four batches at two commercial abattoirs with two different stunning systems, an automatically head-only followed by head-to-chest electrical stunner and a compact carbon dioxide (CO(2)) stunning unit. Meat quality on the loin muscle was assessed by measuring electrical conductivity (PQM) and colour (Minolta CR 200) at 7 h post mortem, and ultimate pH. Loins showing PQM >6.0 μs were classified as clearly pale, soft and exudative (PSE) meat. The incidence of petechiae, ecchymosis and haematomas in the shoulders, loins and hams was also evaluated. In the abattoir equipped with the electrical stunning system, a higher incidence of potentially PSE meat was found compared with the abattoir equipped with CO(2) stunning (35.6 vs. 4.5%). Likewise, electrical stunning increased significatively the incidence of petechiae in the loins, shoulders and hams, and ecchymosis in the loins and hams. Also, the incidence of PSE meat was higher in the Nn pigs compared with NN pigs (24.7 vs. 7.9%). It is suggested that for improving meat quality and reducing incidence of haemorrhages electrical stunning should be avoided. Further improvements in meat quality can be achieved by eliminating the halothane gene specially in CO(2)-stunned pigs. PMID:22062262

  1. Brucellae through the food chain : the role of sheep, goats and springbok (Antidorcus marsupialis as sources of human infections in Namibia

    K. Magwedere

    2011-05-01

    Full Text Available A confirmed case of human brucellosis motivated an investigation into the potential source of infection in Namibia. Since domestic animals are principal sources of Brucella infection in humans, 1692 serum samples were screened from sheep, goats and cattle from 4 presumably at-risk farms and 900 springbok (Antidorcas marsupialis serum samples from 29 mixed farming units for Brucella antibodies by the Rose-Bengal test (RBT and positive cases confirmed by complement fixation test (CFT. To assess the prevalence of human brucellosis, 137 abattoir employees were tested for Brucella antibodies using the standard tube agglutination test (STAT and by enzyme linked immunosorbent assay (ELISA. Cattle and sheep from all 4 farms were negative by RBT and CFT but 2 of the 4 farms (Ba and C had 26/42 and 12/285 seropositive goats, respectively. Post mortem examination of seropositive goats revealed no gross pathological lesions typical of brucellosis except enlarged mesenteric and iliac lymph nodes seen in a single buck. Culture for brucellae from organs of seropositive animals was negative. None of the wildlife sera tested positive by either RBT or CFT. Interviews revealed that besides the case that prompted the investigation, a family and another person from other farms with confirmed brucellosis shared a common history of consumption of unpasteurised goat milk, home-made goat cheese and coffee with raw milk and prior contact with goats, suggesting goats as the likely source of infection. All 137 abattoir employees tested negative by STAT, but 3 were positive by ELISA. The 3 abattoir workers were clinically normal and lacked historical connections with clinical cases. Although goats are often associated with B. melitensis, these studies could not explicitly implicate this species owing to cross-reactivity with B. abortus, which can also infect goats. Nevertheless, these data reinforce the need for a better National Control Programme for brucellosis in Namibia.

  3. A new molecular approach to assess the occurrence of Sarcocystis spp. in cattle and products thereof: preliminary data

    Francesco Chiesa

    2013-11-01

    Full Text Available The genus Sarcocystis consists of more than 200 species. Those protozoa are characterised by a biological cycle composed by two obligatory hosts, definitive and intermediate. Apart from being possibly pathogenic for the intermediate host, a number of authors consider the intestinal sarcocystosis a minor zoonotic disease. Humans, in fact, can act as definitive host for two sarcosporidian species, S. suihominis e S. hominis, being infected through the consumption of raw or undercooked pig and bovine meat, respectively. Other two species could parasitise cattle: S. cruzi and S. hirsuta, having canids and felids as definitive hosts, respectively. The three species differentiate from each other in dimensions and cystic wall morphology, this latter being the basis for taxonomical studies. In 2010, the European Food Safety Authority (EFSA highlighted the absence of reliable methods for epidemiological studies on the presence of Sarcocystis spp. in animals and products thereof. On this basis, the present study has been developed a new molecular method for the identification of Sarcocystis in bovine meat. For the development of the polymerase chain reaction (PCR protocol, a set of samples of bovine meat from cattle (N=15, slaughtered at the didactic abattoir at the Veterinary Faculty of Turin University, has been collected, sequenced and used as reference samples during the study. A second set of samples (N=29, gathered from the same abattoir (N=12 and from abattoirs of Piedmont region (N=17, has been used for applicability tests. The overall positive rate for Sarcocystis spp. in our samples has been 91% (40/44, with S. cruzi representing the species with higher rates (68%, followed by S. hominis (43% and S. hirsuta (2%. Based on the results of specificity and applicability tests performed in this study, the newly developed protocol proved to be reliable and suitable for epidemiologic purposes.

    2012-03-01

    Full Text Available Abstract Background The Irish Horse Industry expanded during the Celtic Tiger boom years, then contracted in the current economic recession. High value horses were traditionally controlled through sale at public auction, private sales and sales to dealers; these are now also being reduced by decreases in production (> 40%, and increases in retirement, re-homing, euthanasia and disposal through Category 2 plants and abattoirs. The absence or banning of horse abattoirs has been shown to have very significant welfare social and economic consequences in the USA. This study described the currently available data on the demographics of unwanted horses in Ireland from 2005 to 2010. Results The majority of horses euthanised by practicing veterinarians are destroyed on medical grounds but the number euthanised at the request of welfare groups and the state, as well as welfare related calls and the number of horses involved in these calls and subsequent visits is increasing reflecting the increasing involvement of the veterinary profession in equine welfare. Welfare groups have limited resources and do not have a tradition of recording data, but they too have reported increasing calls, visits and numbers of horses per visit. Welfare groups provide significant service to equine welfare and the community. Local Authorities report similar trends. Over 300 horses were found dead or required immediate or subsequent euthanasia following welfare group and local authority visits in 2010, which is of national concern. The majority of local authority interfaces with unwanted horses are with urban (60% rather than rural (40% horses. Mortality figures are poor indicators of non-fatal neglect. More horses were admitted into the care of local authorities than welfare groups, reflecting significant state and taxpayer investment in the control of low value horses. Category 2 plants and abattoirs represent a significant state investment in licensing and control in the

    The application of a RAM-based neural network to robot vision is demonstrated for the guidance of a pig evisceration robot. Tests of the combined robot-vision system have been performed at an abattoir. The vision system locates a set of feature points on a pig carcass and transmits the 3D...... coordinates of these points to the robot. An active vision strategy taking advantage of the generalisation capabilities of neural networks is used to locate the control points. A neural network PC-expansion board that provides a new classification every 180 mu s is used to speed up the neural network...

    2013-06-01

    Full Text Available The objective of this study was to evaluate the commercial cuts income and to study the carcass characteristics of non-castrated Nellore males slaughtered at different weights. Forty Nellore males with initial average weight of 350 kg were used. The animals were divided into four groups: animals with 0 and two teeth, with carcass weight up to238,0 kg (young and light carcass; 2-teeth animals with carcass weight ranging from 238,1 to 258,0 kg (young and medium carcass; 2-teeth animals with carcass weight above 258 kg (young and heavy carcass and animals with four or six teeth, regardless of carcass weight (adults. After 84 days of feedlot, the animals were slaughtered in a commercial abattoir. There was no difference for carcass fat characteristics and meat marbling, as well as for commercial cuts percentages, hot carcass weight and yield. Income analysis showed that, depending on the wholesale price differences of the primary cuts of the carcass, studies on cattle breeding should seek to increase the conformation and hindquarter percentage, provided they meet the minimum finishing degree required by the abattoirs.

  16. The study of the pathogenicity of Brucella suis field isolate and transmission ability from pig to human

    Agus Sudibyo

    1998-12-01

    Full Text Available The aim of this work was to study the pathogenicity of Brucella suis field isolate and its ability to transmit the disease from pig to human. The transmission ability of field isolate of B. suis was studied by using 4 brucellosis negative pigs which were put together with one of the artificially infected pig. The transmission ability of the diseases from pig to human was carried out by collecting blood samples from pigs and from the workers of pig farms and abattoir and tested them with the Rose Bengal Plate Test. The result indicated that field isolate of B. suis biotype 1 was pathogenic for pigs with the ID50 of 500 CFU. The infection was widely distributed into several organs or lymphnodes such as retropharingeal, submaxillaris, femoralis, suprascapularis, supramamaria and the spleen. The transmission of brucellosis from artificially infected pigs to negative pig in the group occurred between 4-6 weeks after they were put together. Brucellosis in the pigs was transmittable and causing brucellosis to workers of pig farms and abattoir.

    The objective of this study was to develop a duplex quantitative polymerase chain reaction (qPCR) assay for simultaneous detection of bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhea virus (BVDV) type I and type II. Follicular fluid was collected from a BoHV-1 acutely infected heifer, a BVDV I persistently infected heifer, and from 10 ovaries recovered from an abattoir. Both the BoHV-1 and BVDV contaminated follicular fluid were diluted 1:5 to 1:10(7) using the pooled, abattoir-origin follicular fluid. Each dilution sample was analyzed using the duplex qPCR, virus isolation, reverse transcription-nested PCR (RT-nPCR), and BoHV-1 qPCR. The duplex qPCR was able to simultaneously detect BoHV-1 and BVDV I in the fluid diluted to 1:100 and 1:1000, respectively. These results corresponded with the reverse transcription-nested PCR and BoHV-1 qPCR. Therefore, the duplex qPCR might be used for quality assurance testing to identify these two viruses in cells, fluids and tissues collected from donor animals and used in reproductive technologies.

  18. Tail-biting: a new perspective.

    Taylor, Nina R; Main, David C J; Mendl, Mike; Edwards, Sandra A

    2010-11-01

    Tail-biting data from different studies are difficult to compare because a range of definitions of tail-biting behaviour and tail-biting lesions are used. Although records from abattoirs provide a large database, their usefulness is restricted as tail-biting is under-recorded and environmental and husbandry factors associated with the behaviour are unlikely to be known. Both farm and abattoir data provide no information on the number of pigs biting, only those bitten. Studying individual animals that tail-bite should give a better understanding of the pig's motivation to tail-bite and which of the components of its environment should be adjusted to improve welfare. This review examines the existing literature on tail-biting in pigs but considered from a new perspective using three different descriptive behavioural types, namely, 'two-stage', 'sudden-forceful' and 'obsessive', each of which may have different motivational bases. The article also considers the different environmental and husbandry factors which may affect each type of behaviour and discusses why this is such a complicated field and why it is often difficult to draw conclusions from available research.

    The aim of this study was to identify and determine the genetic diversity of Fasciola species in cattle from Zimbabwe, the KwaZulu-Natal and Mpumalanga provinces of South Africa and selected wildlife hosts from Zimbabwe. This was based on analysis of DNA sequences of the nuclear ribosomal internal transcribed spacer (ITS1 and 2) and mitochondrial cytochrome oxidase 1 (CO1) regions. The sample of 120 flukes was collected from livers of 57 cattle at 4 abattoirs in Zimbabwe and 47 cattle at 6 abattoirs in South Africa; it also included three alcohol-preserved duiker, antelope and eland samples from Zimbabwe. Aligned sequences (ITS 506 base pairs and CO1 381 base pairs) were analyzed by neighbour-joining, maximum parsimony and Bayesian inference methods. Phylogenetic trees revealed the presence of Fasciola gigantica in cattle from Zimbabwe and F. gigantica and Fasciola hepatica in the samples from South Africa. F. hepatica was more prevalent (64%) in South Africa than F. gigantica. In Zimbabwe, F. gigantica was present in 99% of the samples; F. hepatica was found in only one cattle sample, an antelope (Hippotragus niger) and a duiker (Sylvicapra grimmia). This is the first molecular confirmation of the identity Fasciola species in Zimbabwe and South Africa. Knowledge on the identity and distribution of these liver flukes at molecular level will allow disease surveillance and control in the studied areas. PMID:26476916

    The objective of this paper is to review the scientific literature to identify on-farm factors that contribute to market weight pig transportation losses. Transportation of market weight pigs is an essential element to the multisite pork production model used in the United States. In 2011 alone, approximately 111 million market weight pigs were transported from the finishing site to the abattoir. For pigs, the marketing process can present a combination of potentially novel, physical, and/or unfamiliar experiences that can be stressful. If the pig cannot cope with these sequential and additive stressors, then an increased rate of transportation losses could occur with a detrimental effect on pork carcass value. Current yearly estimates for transport losses are 1 million pigs (1%). A variety of market weight pig and farm factors have been reported to detrimentally affect transportation losses. By understanding how pigs interact with their environment during marketing, researchers, producers, and personnel at the abattoir may begin to identify, prioritize, and attempt to minimize or eliminate these stressors. This process will ultimately decrease transportation losses, improve pork quality, and increase profitability. PMID:23478817

  1. REVIEW OF RESEARCH IN VETERINARY PARASITOLOGY IN THE RESEARCH INSTITUTE FOR VETERINARY SCIENCE (RIVS SINCE 1983

    2012-09-01

    Full Text Available Studies on gastrointestinal parasites and the epidemiology and pathogenesis of blood protozoa in ruminants have been undertaken during the last few years. An abattoir survey for a period of one year showed that most large ruminants slaughtered in the Bogor abattoir were infected with nematodes, about half with trematodes and few with blood parasites. Worm infections were also common in small ruminants but none were infected with blood protozoa. Some field studies on Fasciola infection in large ruminants showed that these animals were susceptible to the disease. The seasonal prevalence of fascioliasis is not yet fully determined; management systems and the local geography play an important role. Most anthelmintics were effective against worm infection in large and small ruminants. A new flukicide (triclabendazole is highly effective against both immature and mature liver flukes. Studies on the epidemiology and pathogenesis of trypanosomiasis in cattle and buffalo have been conducted since 1982. The results indicate that T. evansi is prevalent in five regions in Java; the prevalence rates are higher in Sahiwal and Belmont Red than Ongole cattle or buffalo. ELISA values increase with increasing age of the animals. Buffaloes are more susceptible than cattle. Naganol is the drug of choice for control of trypanosomiasis in Indonesia.

    Full Text Available The spatial distribution of airborne bacterial contamination (with Total aerobic bacteria, Gram-negative bacteria, Coliforms, Staphylococci and Streptococci was studied within the municipal abattoir of Constantine (North-East of Algeria. Open plate air samples were collected at twenty sampling locations weekly during two months. At the same chosen locations, temperature and humidity of the air were measured. The spatial distribution of bacterial contamination was studied using a Geographic Information System. The viscera processing section recorded the highest bacterial concentration and poor correlations had been recorded between bacterial counts and the environmental conditions within the abattoir. The high air bacterial loads recorded all over the slaughterhouse were consequence of the execution of all processing operations within the same section (for both bovine and ovine carcasses associated to the absence of structural barriers, spatial separation between processing operations and uncontrolled airflow. This study highlights the poor hygienic level of the municipal slaughterhouse of Constantine. The implementation of serious measures is needed to reduce the risk of contamination and proliferation of pathogens in meat during slaughtering processes.

  3. Animal welfare at markets and during transport and slaughter.

    Gregory, N G

    2008-09-01

    This review highlights some recent developments in our understanding of stress and physical injuries that occur before and during transport to slaughter, during handling at livestock markets, and at the time animals are put-up for slaughter within abattoirs. Stress in pigs during transfer to the stunning point within the abattoir has important effects on meat quality, and there is growing evidence that strenuous exercise or CO(2) stunning can contribute to oxidative rancidity in pigs, poultry and fish. In the EU, putting cattle through a crush in order to check that their eartag numbers correspond to their passport numbers is imposing additional stress, and there are reports that it is leading to greater hide contamination with Escherichia coli O157. Recent developments in stunning and slaughter include a better understanding of the causes of variation in captive bolt gun performance, the effectiveness of poll instead of frontal shooting in water buffalo, the prevalence of false aneurysms in carotid arteries during shechita and halal slaughter, and the stress effects of CO(2) stunning in fish. Stunning pigs with 90% CO(2) leads to less PSE meat than 80% CO(2). There have been concerns about the physical activity that cattle show following electrical stunning with an electrically induced cardiac arrest, and with electrical stunning using DC waveforms in broiler chickens. There is also growing concern about the hygiene problems that exist in wet markets, where animals are slaughtered alongside meat that is on display to customers. PMID:22063164

    To the present study, the capacity of food grade trissodic phosphate to reduce bacterial spoiling and pathogenic effect on bovine meat from three different categories of abattoirs was estimated, as well as shelf life of bovine meat kept under refrigeration. Trissodic phosphate was efficient to reduce bacterial spoiling and pathogenic effect, represented by mesophils and psychrotrophs, indicator microorganisms, fecal coliforms and pathogens such as Staphylococcus aureus and Salmonella. The shelf life of treated bovine meat was influenced by the abattoir category and by the treatment with 10% solution of trissodic phosphate which represented an increase of 26.66%, 27.77% and 31.03% in the durability of meat coming from abattoirs A, B and C, respectively.

    2007-02-01

    The first objective of this study was to test the ability of systems of weighing and classifying bovine carcasses used in commercial abattoirs in Ireland to provide information that can be used for the purposes of genetic evaluation of carcass weight, carcass fatness class, and carcass conformation class. Secondly, the study aimed to test whether genetic and phenotypic variances differed by breed of sire. Variance components for carcass traits were estimated for crosses between dairy cows and 8 breeds of sire commonly found in the Irish cattle population. These 8 breeds were Aberdeen Angus, Belgian Blue, Charolais, Friesian, Hereford, Holstein, Limousin, and Simmental. A multivariate animal model was used to estimate genetic parameters within the Holstein sire breed group. Univariate analyses were used to estimate variance components for the remaining 7 sire breed groups. Multivariate sire models were used to formally test differences in genetic variances in sire breed groups. Field data on 64,443 animals, which were slaughtered in commercial abattoirs between the ages of 300 and 875 d, were analyzed in 8 analyses. Carcass fat class and carcass conformation class were measured using the European Union beef carcass classification system (EUROP) scale. For all 3 traits, the sire breed group with the greatest genetic variance had a value of more than 8 times the sire breed group with least genetic variance. Heritabilities ranged from zero to moderate for carcass fatness class (0.00 to 0.40), from low to moderate for carcass conformation class (0.04 to 0.36), and from low to high for carcass weight (0.06 to 0.65). Carcass weight was the most heritable (0.26) of the 3 traits. Carcass conformation class and carcass fatness class were equally heritable (0.17). Genetic and phenotypic correlations were all positive in the Holstein sire breed group. The genetic correlations varied from 0.11 for the relationship between carcass weight and carcass fatness class to 0.44 for the

    Full Text Available Livestock-associated bacteria with resistance to two or more antibiotic drug classes have heightened our awareness for the consequences of antibiotic consumption and spread of resistant bacterial strains in the veterinary field. In this study we assessed the prevalence of concomitant colonization with livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA and enterobacteriaceae expressing extended-spectrum betalactamases (ESBL-E in farms at the German-Dutch border region. Nasal colonization of pigs with MRSA (113/547 (20.7% was less frequent than rectal colonization with ESBL-E (163/540 (30.2%. On the individual farm level MRSA correlated with ESBL-E recovery. The data further provide information on prevalence at different stages of pig production, including abattoirs, as well as in air samples and humans living and working on the farms. Notably, MRSA was detected in stable air samples of 34 out of 35 pig farms, highlighting air as an important MRSA transmission reservoir. The majority of MRSA isolates, including those from humans, displayed tetracycline resistance and spa types t011 and t034 characteristic for LA-MRSA, demonstrating transmission from pigs to humans. ESBL-E positive air samples were detected on 6 out of 35 farms but no pig-to-human transmission was found. Detection of ESBL-E, e.g. mostly Escherichia coli with CTX-M-type ESBL, was limited to these six farms. Molecular typing revealed transmission of ESBL-E within the pig compartments; however, related strains were also found on unrelated farms. Although our data suggest that acquisition of MRSA and ESBL-E might occur among pigs in the abattoirs, MRSA and ESBL-E were not detected on the carcasses. Altogether, our data define stable air (MRSA, pig compartments (ESBL-E and abattoir waiting areas (MRSA and ESBL-E as major hot spots for transmission of MRSA and/or ESBL-E along the pig production chain.

    1.1 This guide outlines procedures for the irradiation of pre-packaged refrigerated and frozen processed meat and poultry products. Note 1—The Codex Alimentarius Commission defines "meat" (including poultry and game) as "the edible part of any mammal slaughtered in an abattoir," and "poultry meat" as "the edible part of slaughtered domesticated birds, including chicken, turkeys, ducks, geese, guinea-fowls, or pigeons." (CAC/RCP 13-1976) Note 2—Current U.S. regulations limit the definition of livestock species to cattle, sheep, swine, goat, horse, mule, or other equine and poultry species to chicken, turkey, duck, goose, and guinea (2, 3). 1.2 This guide addresses all refrigerated and frozen meat and poultry products NOT covered by Guide F 1356. 1.3 This guide provides information regarding absorbed doses used for inactivation of parasites and reduction of bacterial load. Such doses are typically less than 10 kilogray (kGy).

  10. Expression Marker-Based Strategy to Improve Beef Quality

    Cassar-Malek, Isabelle; Picard, Brigitte

    2016-01-01

    For beef cattle research, a main objective is to control concomitantly the development of muscles and the qualities of beef cuts. Beef quality is a complex phenotype that is only detectable after slaughter and is highly variable. The beef industry is in need of tools to estimate beef quality of live cattle or online in abattoirs, with specific attention towards sensory attributes (tenderness, juiciness, flavour, and colour). Identification of relevant genetic and genomic markers is ongoing, especially for tenderness—a top priority quality attribute. In this paper, we describe the steps of an expression marker-based strategy to improve beef sensory quality, from the discovery of biomarkers that identify consistent beef and the biological functions governing beef tenderness to the integration of the knowledge into detection tests for desirable animals. These tools should soon be available for the management of sensory quality in the beef production chain for meeting market's demands and assuring good quality standards. PMID:27066527

  11. Production of bioactive peptide hydrolysates from deer, sheep and pig plasma using plant and fungal protease preparations.

    Bah, Clara S F; Bekhit, Alaa El-Din A; Carne, Alan; McConnell, Michelle A

    2015-06-01

    Plasma separated from deer, sheep and pig blood, obtained from abattoirs, was hydrolysed using protease preparations from plant (papain and bromelain) and fungal (FP400 and FPII) sources. Antioxidant and antimicrobial activities of the peptide hydrolysates obtained after 1, 2, 4 and 24h of hydrolysis, were investigated. The release of trichloroacetic acid-soluble peptides over the hydrolysis period was monitored using the o-phthaldialdehyde (OPA) assay, while the hydrolysis profiles were visualised using SDS-PAGE. The major plasma proteins in the animal plasmas were identified using MALDI-TOF-TOF MS. Hydrolysates of plasma generated with fungal proteases exhibited higher DPPH radical-scavenging, oxygen radical-scavenging capacity (ORAC) and ferric reducing antioxidant power (FRAP) than those generated with plant proteases for all three animal plasmas. No antimicrobial activity was detected in the hydrolysates. The results indicated that proteolytic hydrolysis of animal blood plasmas, using fungal protease preparations in particular, produces hydrolysates with high antioxidant properties. PMID:25624206

    In national surveillance programmes of broiler flocks carried out in Denmark during 1998 and 1999, 89,110 samples for Campylobacter representing 8911 broiler flocks were taken at 10 different abattoirs, and 44,550 samples for Salmonella were taken from the same flocks in the broiler houses at the...... farms. Of the swabs, 42.5% were Campylobacter positive. Most positive samples were found during July, August and September, while the lowest number of positive samples were found during January, February, March and April. Of the flocks, 5.5% were Salmonella positive, but no seasonal variation was...... observed. For each flock, the presence of Campylobacter and Salmonella was recorded in order to estimate the possible correlation between colonisation with the two pathogens. In conclusion, no significant effects on intensive cleaning and disinfection procedures on Campylobacter occurrence could be...

  13. Some issues of environmental concern in Kampala, the capital city of Uganda.

    Matagi, Samuel Vivian

    2002-07-01

    Kampala, the capital city of Uganda is the administrative, political, commercial, industrial, educational and cultural centre of Uganda. The city has an area of 190 km2 and is located 8 km north of Lake Victoria (the second largest fresh water lake in the world) and approximately 42 km north of the equator. The population varies from about 1.2 million during the day to perhaps 0.9 million at night. The anthropogenic activity of this population far exceeds the infrastructure capacity of the city, leading to the deterioration of the urban environment. This article highlights the major sources of environmental degradation and pollution in the city, which include solid waste, abattoir waste, sewage, sanitation, drainage, industrial pollution, traffic pollution, atmospheric pollution, urban agriculture, rapid urbanisation and water hyacinth.

    2011-05-01

    Targets for maximum acceptable levels of Salmonella in pigs and pork are to be decided. A stochastic simulation model accounting for herd and abattoir information was used to evaluate food safety and economic consequences of different surveillance and control strategies, based among others on Danish surveillance data. An epidemiological module simulated the Salmonella carcass prevalence for different scenarios. Cost-effectiveness analysis was used to compare the costs of the different scenarios with their expected effectiveness. Herd interventions were not found sufficient to attain Salmonella carcass prevalence information becomes available. This framework contributes to informed decision-making for a more cost-effective surveillance and control of Salmonella in pigs and pork. PMID:20653990

    A higher herd prevalence of antibodies (ELISA) to Yersinia enterocolitica O:3 was found in conventional slaughter production (86.0% seropositive herds) than in conventional farrow-to-finish herds (53.1% seropositive herds). The herd prevalence of antibodies to Y. enterocolitica in multiplying herds...... (56.1%) was similar to the level in the conventional farrow-to-finish herds. An epidemiological study in conventional pig herds demonstrated that farrow-to-finish production (odds ratio, OR = 0.15) was an important protective factor. Using under-pressure ventilation (OR = 0.33) and manual feeding of...... slaughter pigs (OR = 0.44) also lowered the herd prevalence. The most expressed risk factor was using an own farm vehicle for transport of slaughter pigs to abattoirs (OR = 12.92).

  17. PRESENCE OF Listeria monocytogenes IN HEALTHY CATTLE AT SLAUGHTERING: FIRST RESULTS

    E. Pavoletti

    2013-02-01

    Full Text Available Listeria monocytogenes is an ubiquitous pathogen occasionally present in the intestinal tract of various animal species. The aim of this study was to assess the incidence of Listeria spp. and Listeria monocytogenes in faeces of healthy cattle at slaughtering. Listeria spp. was isolated in 18 out of 220 (8.2% faecal samples, and Listeria monocytogenes was isolated in 3 faecal samples (1.4%. From the 220 faecal samples were also isolated 9 strains of L. grayi, 4 strains of L. innocua and 2 strains of L. ivanovii. Although limited, our results show that animal faeces can represent a source of L. monocytogenes contamination of carcasses in abattoirs and can be a potential hazard to human health.

    Over 1 year, from January to December 1999, a total of 173 slaughtered sheep at Al-Mahala abattoir were examined for presence of nematode parasites. Eighteen sheep (10.4%) were infected with eight different species of nematodes. The prevalence rates of detected nematode parasites were; Haemonchus contortus (3.5%), Haemonchus placei (1.7%), Trichuris ovis (5.8%), Parabronema skrjabini (2.9%), Ostertagia trifurcata (1.2%), Chabertia ovina (0.6%) and Strongyloides papillosus (0.6%), and Graphidiops species (2.9%). The seasonal prevalence of the infection with the nematode parasites was studied and the highest rate was during autumn (15.2%) followed by summer (11.1%) and winter (9.4%) while the lowest rate was during spring (5.6%).

    Background: The predominant food borne pathogen in the western world today is Campylobacter. Campylobacter specific bacteriophages (phages) have been proposed as an alternative agent for reducing the burden of Campylobacter in broilers. One concern in relation to phage biocontrol is the narrow host...... range often displayed by phages. To identify the potential of phages as a Campylobacter reducing agent we needed to determine their infectivity on a panel of isolates representing the Campylobacter strains found in broilers as well as humans. Results: In this study, Campylobacter phages were isolated...... from the intestines of broilers and ducks and from abattoir sewage. Twelve phages were investigated to determine their ability to infect the Campylobacter Penner serotypes commonly present in Danish poultry and patients with campylobacteriosis. A total of 89% of the Campylobacter jejuni strains and 14...

    Full Text Available Echinococcosis is the major helminthic parasitic infection in Iran. The health hazard and economic loss in man and livestock is significant. In this study 3 major topics as the prevalence of hydatid cyst in human population, in livestock and echinococcosis in stray dogs, were studied. Total of 1114 serum samples in different age groups in Sanandaj and Divandareh area of Kurdestan province in west of Iran were examined by indirect immunoflurecent test (IFA. In Sanandaj area 3.3% and in Divandareh 9.5% of serum samples were positive for hydatidosis. In livestock using abattoir inspection the rate of infection was 51.9% and 28.02% for sheep and cattle, respectively. Nine stray dogs (44% autopsied in Sanandaj were positive for Echinococcosis.

    Full Text Available During 2006 one hundred and three white veal calves slaughtered at an abattoir in Isernia (Italy were examined for E. coli O157 intestinal carriage and carcass contamination, using Immuno-Magnetic Separation (IMS and multiplex PCR. Faecal material before slaughtering and carcass samples, using sponge-bag, were collected. E. coli O157 isolates were found in 10 (9,71% faecal and 9 (8,7% carcass samples. PCR analysis showed that all the strains from faecal and from carcass samples carried eaeA, hlyA and stx2 genes, while five strains stx1 gene. The results confirm that the slaughter practices can largely influence the rate of E. coli O157 carcasses contamination and suggest that white veal calves meat could be an important risk for human health.

    Wohlfahrtiimonas chitiniclastica is an emerging zoonotic bacterium commensally living in larvae of particular flies. It has been associated with human and animal infections but never isolated from food. In the present study, a whole chicken carcass was rinsed in buffered peptone water which was then inoculated into BHI and the growth plated onto selective medium. Species identification was performed by MALDI-TOF MS. Those bacteria identified as W. chitiniclastica were subjected to 16S rRNA sequencing for confirmation and MEGA software was used to obtain their phylogenetic position. The findings of this study raise concerns regarding the abattoir, transport and stock practices of frozen meat carcasses and should be of interest with regard to microbiology, entomology and food production.

    Full Text Available Aim: This study was undertaken to identify Paramphistomum cervi on the basis of its morphology and histology to be the common cause of paramphistomosis in infected sheep and its differentiation from other similar Paramphistomes in Gujarat. Materials and Methods: Adult rumen flukes were recovered from the rumen of naturally infected sheep slaughtered in various abattoirs in Gujarat. Some adult flukes were flattened and stained in Borax carmine, and some were sectioned in the median sagittal plane and histological slides of the flukes were prepared for detailed morphological and histological studies. Result: Microscopic pictures of the parasite used in identification define the similarity in the morphology and histology of the anterior sucker, pharynx, esophagus, genital atrium, posterior sucker (acetabulum and testes to the P. cervi. Conclusion: It can be concluded that the most common species found in sheep infected with Paramphistomosis is P. cervi on the basis of its histo-morphological appearance in Gujarat.

    place, a receiving herd needed to be found. The distance, in which the receiving herd should be found, was calculated from movement data for animals and from data from trucks and abattoirs for movements to slaughter and milk tankers. For persons visiting herds, we used a combination of expert opinions......Geographical locations of the farms are the core in these models. We used geographical data, number of animals and specification of herd types for the 50,853 herds in the Danish Husbandry Register (CHR) in 2007. For each herd, the daily probability of moving animals, to another herd or to the......, disease was simulated to spread via direct contacts (movements of animals), indirect contacts (trucks and persons) and local spread (mice, birds, airborne spread in limited distances). Furthermore, in some scenarios airborne spread was included. For all contact types, when a contact was simulated to take...

    2014-02-01

    Prediction of ultimate pH (measured 48 h post mortem; pH(u)) in beef from Visible-near infrared (VIS-NIR) spectra collected 20 to 40 min post mortem was assessed. Spectra were collected from carcasses (cows: n = 86, bulls: n = 170, steers: n = 363, and heifers: n = 38) in a commercial hot boning abattoir under routine conditions. Partial Least Squares (PLS) models showed limited accuracy with RMSE for validation equal to 0.26, 0.20 and 0.36 for the All-animals, Non-bulls and Bulls models, respectively. The pH(u)-PLS-predicted values were used to segregate carcasses as normal (pH(u)spectroscopy (NIRS) could be used for on-line classification of beef carcasses based on pH(u). PMID:24211544

    Full Text Available Fasciola spp. were collected from naturally infected cattle at a local abattoir of Khanh Hoa province, Vietnam, for morphological and genetic investigations. Microscopic examination detected no sperm cells in the seminal vesicles, suggesting a parthenogenetic reproduction of the flukes. Analyses of sequences from the first and second internal transcribed spacers (ITS1 and ITS2 of the ribosomal RNA revealed that 13 out of 16 isolates were of Fasciola gigantica type, whereas three isolates presented a hybrid sequence from F. gigantica and Fasciola hepatica. Interestingly, all the mitochondrial sequences (partial COI and NDI were of F. gigantica type, suggesting that the maternal lineage of the hybrid form is from F. gigantica. No intra-sequence variation was detected.

    ABSTRACT To clarify the pathophysiology of left displaced abomasum (LDA), beef cattle fed high-starch diets were examined. The abomasal pH in beef cattle with LDA was lower than that in non-LDA reference animals (data from beef cattle at an abattoir), suggesting that it facilitated acidity. Bacteriological examinations of the abomasal fluid in cattle with LDA revealed the presence of Pseudomonas spp., Clostridium spp. and Candida spp., presumably reflecting the accelerated influx of ruminal fluid into the abomasum. Biochemical analyses of serum revealed that LDA cattle had higher lactic acid and lower vitamin A and E levels than non-LDA reference animals. These results indicate that beef cattle with LDA may suffer from vitamin A and E deficiencies due to maldigestion of starch and the high acidity of abomasal fluid. PMID:24813464
