Increases in pig major acute-phase protein in wasting pigs brought to the abattoir.

Plasma proteins of wasting pigs were quantitatively and qualitatively compared with those of normal fattening pigs. Higher expression of a 120 kDa protein was observed in the plasma of wasting pigs by SDS-PAGE. This protein was identified as pig major acute-phase protein (Pig-MAP) by proteomic analysis using two-dimensional electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The plasma concentration of Pig-MAP in wasting pigs was 7-fold higher than that of normal ones.

Quantitative risk assessment of the risks associated with the importation of pigs to abattoirs.

This paper presents a quantitative risk assessment method based on the portrayal of risks using scenario trees, the translation of evidence into probability curves and the aggregation of scenarios using Latin Hypercube simulation. An example of a quantitative risk assessment on the importation of swine for slaughter illustrates the interpretation of evidence of two swine disease risks: pseudorabies (Aujeszky's disease) and brucellosis.

Use of antimicrobial agents in official abattoirs under meat inspection in the United States of America.

Facilities and equipment which are contaminated by a diseased carcass during slaughter and processing operations must be made free from microorganisms of human health concern before being used again. Therefore, a rapid-acting microbicidal agent is necessary to enable the swift resumption of operations. Currently, water heated to 180 degrees F (82.2 degrees C) is the antimicrobial agent of choice, as this rapidly kills microbes without leaving a residue which could jeopardize food products.

A cluster of leptospirosis among abattoir workers.

In early December 1998, the Northern Rivers Public Health Unit (north-eastern New South Wales) was alerted to a possible cluster of leptospirosis cases by the supervising scientist of the Western Pacific Region World Health Organization/Food and Agricultural Organization Collaborating Centre for Reference and Research on Leptospirosis. Investigation revealed a cluster of eight leptospirosis cases diagnosed during October and November 1998. All were employees of a local meat works. Leptospira serovars isolated included pomona and hardjo. Symptoms included headache, fever, muscle pain, sore eyes, abdominal pain, vomiting, jaundice, and rash. Five of the eight cases were hospitalised. The infection could not be traced to any particular source. Unfortunately, records of stock killed during the exposure periods were not available. All cases reported exposure to large volumes of animal urine during the course of their work. Protective clothing provided included an apron, gloves, and rubber boots. All of the patients said they wore rubber boots and seven of the eight wore the apron provided. Only two patients reported wearing gloves, the remainder thought these were too difficult to work in.

Adenosine triphosphate bioluminescence as a method to determine microbial levels in scald and chill tanks at a poultry abattoir.

According to Hazard Analysis of Critical Control Points (HACCP) programs developed for the poultry industry, poultry processing waters should be actively monitored to minimize cross-contamination between chicken carcasses. In order to monitor HACCP programs, a test is required that provides results on a real time basis. A modified adenosine triphosphate (ATP) bioluminescence test has been developed that can assess microbial levels in poultry processing waters within 15 min. A study was conducted to determine the effectiveness of this test for examining scald, prechill, and chill tank waters. The results showed that the modified ATP bioluminescence method gave results comparable to plate counts. The microbial levels were dependent on the tank and the time of sampling. The highest microbial levels were detected in the scald tank. In all three tanks, the microbial levels increased over time during the day.

Common conditions leading to cattle carcass and offal condemnations at 3 abattoirs in the Western Province of Zambia and their zoonotic implications to consumers.

From a total of 32 717 cattle slaughtered, 183 whole carcass condemnations were attributable to 9 diseases and conditions, namely, tuberculosis (TB), cysticercosis, emaciation, generalised lymphadenitis, jaundice, abscesses, moribund, sarcosporidiosis and odour. Bovine TB was the most important cause of condemnations (152/183, 83.1%). Bovine cysticercosis and sarcosporidiosis accounted for 5/183 (2.7%) and 8/183 (4.4%), respectively, while each of the remaining conditions contributed less. Among the many conditions responsible for offal/organ condemnations were fascioliasis, contagious bovine pleuropneumonia, hydatidosis and TB. In terms of number and weight, Fasciola gigantica infections made livers and lungs the most condemned offals (20.1% and 0.7%, respectively). Hydatidosis was the cause of 0.9% lung and 0.1% liver losses. Cysticercus bovis contributed to only 0.05% of all inspected tongues, hearts, and heads. TB was very rare in heads (0.01%). The financial impact of whole carcasses and offals condemned during the study period was enormous and deprived livestock farmers of the much needed revenue and consumers of protein sources. Much or all of the condemned material that could have been useful was wasted by not being retrieved for conversion to processed meat, bone meal or pet food. Failure to detect lesions of potential zoonotic diseases at slaughter poses a health risk to consumers especially when meat is eaten undercooked.

A pilot study on post-evisceration contamination of broiler carcasses and ready-to-sell livers and intestines (mala) with Campylobacter jejuni and Campylobacter coli in a high-throughput South African poultry abattoir.

To assess post-evisceration contamination of broiler carcasses, 300 samples were randomly selected during routine slaughter in the winter of 2004. The samples originated from 50 chicken carcasses, taken directly after evisceration, as well as 25 samples from ready-to-sell packages of fresh intestines (mala) and livers. The samples were taken in batches over a period of 4 weeks to allow randomised sampling from different farms of origin. Conventional culture-based detection methods of Campylobacter spp. usually need 4-6 days to produce a result. The polymerase chain reaction (PCR) used for this study took less than 32 hours. The average contamination rates with Campylobacter in both the skin and liver samples were 24%, and 28% for intestines. Chicken and chicken products, especially livers and intestines, form an integral part of the traditional diet of many Black South Africans, as they are cheap and readily available in bulk and un-chilled for direct distribution, mainly through street vending and other informal retail outlets. This sudy showed that Campylobacter spp. are prevalent in poultry in South Africa. The handling of poultry meat and products contaminated with this organism in households and the potential for cross-contamination of other foods presents a high risk of infection to consumers in South Africa. The study also emphasised the need for further research in this field.

Prevalence of Salmonella spp. and Yersinia enterocolitica in finishing swine at Canadian abattoirs.

The prevalence of Salmonella spp. and Yersinia enterocolitica in finishing swine was evaluated using samples of cecal material. Samples were taken at six different slaughterhouses from 1420 healthy, 5-month-old pigs, raised by 223 producers in Quebec (1009 samples), Ontario (283), and Manitoba, Canada (128). Two different broth media (Rappaport-Vassiliadis and Tetrathionate brilliant green) were used for the selective enrichment of Salmonella spp. The recovery of Y. enterocolitica was done by a cold enrichment technique, followed by plating on a selective media (cefsulodin-irgasan-novobiocin agar). Prevalence (with a 95% confidence interval) of Salmonella spp. and Y. enterocolitica were, respectively, 5.2% (4.0 to 6.4%) and 20.9% (18.8 to 23.0%). Overall, 24.6% of the animals tested were positive for one or both of these pathogens. Since only a few herds (2.8%) appeared to be highly contaminated by Salmonella spp., efforts should be undertaken in priority to control this pathogen in those herds.
