ABSTRACT

Poultry processing activities require large amount of high quality water for processing, cleaning and cooling. Contamination of water at any point in the processing stage is likely to affect meat hygiene. Waste water generated during these activities typically has high presence of organic material such as blood, fat, flesh and excreta. In developing countries like Nigeria where access to portable water is lacking, it is not uncommon to “reuse” rinse water for processing several batches of poultry carcass.Several samples were collected from three poultry slaughterhouses within Jos metropolis at intervals for a period of 6 months to check for presence of Salmonella during various stages of processing. Salmonella was isolated from at least one of the four matrices in the three LBM with an overall prevalence of 20.2%. Of the 84 samples collected, 17 contained Salmonella. With regard to the matrices, there was no difference in Salmonella prevalence among the four matrices considered. Four different serotypes were identified with Salmonella Llandoff having the highest isolation rate in all the matrices sampled (58.8%), followed by, S. Kentucky (17.7%), S. Schwarzengrund and S. Havana had the lowest isolation rate (11.8%). S. Llandoff was isolated in all the matrices and was distributed across the three LBM whereas the other less frequent serovars had a more circumscribed distribution. Resistance to Methicillin, Penicillin, Erythromycin and Oxacillin was 100% for all the serotypes while Gentamicin had the lowest resistance (5.9%).This is one of few studies on the occurrence and antimicrobial resistance profile of Salmonella in poultry slaughter slab (processing plants) in Nigeria. The relatively high prevalence rate documented in this study may be attributed to the generally poor infrastructure, lack of well-equipped poultry slaughter houses, lack or inadequate water supply at these markets which hampers the ability of handlers to maintain good sanitary and hygiene conditions of the carcass, environment and themselves. Data collected could be valuable for instituting effective intervention strategies for Salmonella control in Nigeria with the aim of reducing Salmonella spread from poultry to humans.
