Delivery of infected pigs to the slaughterhouse is a major source of pork meat contamination by bacterial hazards to humans. We propose a model of Salmonella spread within a farrow-to-finish pig herd, assuming the prevalence in infected delivered pigs depends on the whole pig life-time and growing process. This stochastic discrete-time model represents both the population dynamics in a farrow-t...

The aim of the present study was to determine the Trichinella seroprevalence in slaughter pigs in Kathmandu Valley, Nepal. Serum samples were obtained from 400 pigs at 4 major slaughterhouses and tested for Trichinella antibodies by ELISA using larval excretory-secretory (E/S) antigen. Four were positive and one was equivocal, giving a Trichinella seroprevalence of 1% (95% CI: 0.27 - 2.54). On ...

BACKGROUND Tularemia is a zoonotic disease caused by the Gram-negative bacterium Francisella tularensis. Human infections often occur through manipulation of infected animals or animal carcasses. METHODS In this study, we determined the tularemia seroprevalence in butchers and slaughterhouse workers in 10 counties of Sistan and Baluchestan Province in Iran. RESULTS A mean seroprevalence of ...

In Cyprus, echinococcosis (Echinococcus granulosus) was an important public and animal health problem until the 1970s. In 1971, the Department of Veterinary Services instigated a control programme, which was based on an island model, using arecoline testing, euthanasia of positive dogs, control of dog breeding, elimination of stray dogs and control measures in slaughterhouses. The first program...

This study aims at investigating Salmonella environmental contamination of trucks and lairage pens and evaluating the efficiency of an improved cleaning and disinfection protocol to reduce Salmonella environmental contamination. During four days, the lairage of two French pig slaughterhouses were sampled twice a day when pigs were present and once at the end of the week after the cleaning proto...

The prevalent microbial growth on carcasses before and after overnight cooling in an ostrich abattoir and de-boning plant was investigated. The effect of warm or cold trimming of the carcasses was examined together with possible causes of contamination along the processing line. An attempt was made to link the prevalent microorganisms that were identified from carcasses to those from specific e...

A mathematical model of chicken processing that quantitatively describes the transmission of Campylobacter on chicken carcasses from slaughter to chicken meat product has been developed in Nauta et al. (2005). This model was quantified with expert judgment. Recent availability of data allows updating parameters of the model to better describe processes observed in slaughterhouses. We propose Ba...

A study was conducted in northern Thailand to characterize Campylobacter spp isolated from chickens at farms, slaughterhouse, and chicken meat at fresh markets, and stools from chicken farmers as well as neighboring crop farmers who served as controls. The Campylobacter isolates were collected during the rainy months of the years 2000, 2001, and 2002. Standard methods were used for primary isol...

Pan-European surveillance of bacteraemia caused by methicillin-resistant Staphylococcus aureus (MRSA) shows it to be a problem affecting all European countries, although there is marked geographical variation in prevalence. Although the proportion of S. aureus bacteraemia due to MRSA is declining in many countries, data from the European Antimicrobial Resistance Surveillance System (EARSS) for ...

The national bovine tuberculosis and brucellosis eradication pro­ gramme in Australia was developed in 1968 and officially started in July 1970 on a regional basis. The method of prophylaxis of bovine tuberculosis consis­ ted of a strict identification and systematic tuberculin testing of cattle as well as the inspection of carcasses at the abattoir in order to find the original herd of tubercu...
