Abstract

The hide and viscera of cattle entering a slaughter facility are potential sources of contamination of carcasses including significant pathogens such as Escherichia coli O157:H7, Campylobacter spp. and Salmonella spp. If evisceration is correctly performed, visceral contents do not therefore contribute significantly to the overall contamination of the carcass. However, it is much more difficult to restrict contamination from the hide. The aim of this work is to investigate the relationships between the levels of dirt and contamination on the hide of animals presented for slaughter and the levels of contamination on the resultant carcasses. Cattle were visually inspected in the lairage of 2 abattoirs and assigned to a category ranging from 1 (very clean) to 5 (very dirty) depending on the observed cleanliness of the hide. Samples of hides and carcasses were taken from 50 animals for enumerate total viable counts, Enterobacteriaceae and Escherichia coli. The results show that there is a direct correlation between animal dirtiness and total bacterial count of the carcasses.
