SIXTY SAMPLES OF TISSUE FRAGMENTS WITH LESIONS SUGGESTIVE OF TUBERCULOSIS FROM BOVINE ABATTOIRS, KEPT IN SATURATED SOLUTION OF SODIUM BORATE, WERE SUBJECTED TO FOUR TREATMENTS: 4% NaOH (Petroff Method), 12 % H2SO4 and 1.5% HPC (1-Hexadecylpyridinium Chloride) decontamination, and physiological saline solution (control). The HPC method showed the lowest contamination rate (3%) when compared to c...

Recent research has shown that much preharvest Salmonella enterica infection in pigs occurs immediately before slaughter during this rest period in the contaminated abattoir holding pens. The objective of this study was to evaluate a potential intervention strategy to reduce the prevalence of S. enterica-positive pigs at slaughter, which consisted of resting pigs prior to slaughter on their tra...

One hundred and forty-four samples of chilled turkey meat from six flocks, taken directly from the slaughterhouse, and 100 samples of turkey meat retail products were examined. Over one-quarter (29.2%) of the tested samples from the slaughterhouse were Campylobacter positive, showing high variability in the flocks. The lowest percentage of Campylobacter-positive samples was found in flocks I an...

Surveillance at the slaughterhouse level for animal health and food safety purposes encompasses examination for the presence of pathology, pathogens, drug residues, chemical contaminants and antimicrobial resistance. Government, industry and academia are the primary proponents of such surveillance. A variety of policies and policy instruments from voluntary to legislative may be applied to prom...

higher in the winter months, when the horse’s thicker coat makes an ideal microclimate for the louse. Reports from the USA (Jones and DiPietro 1996) and Canada (Wright 1999) state that infestations of domestic horses with lice are rare; this could be due to management practices, such as combing and clipping, or because of the use of broad-spectrum ectoparasiticides. However, lice are apparently...

Rinderpest was confirmed in Kenya in 1986, 1987, 1988 and 1989. Three epidemiologically distinct events appear to have occurred: repeated outbreaks in West Pokot district related to cross-border movement of stock, an outbreak in Marsabit district in 1987 (thought to have been caused by illegal movement of cattle, possibly in vehicles, from countries further north) and a series of related outbre...
