Contamination of Beef Carcasses during Hide Removal and use of a Test Bacterial Decontamination System on Beef HideIn Ireland, the Abattoirs Act, 1988 (Veterinary Examination) (Amendment), 1998 (S.I. No. 6, 1998) empowers the ante mortem veterinary inspector to reject animals for slaughter or require slaughter under special conditions, based on the level of visible hide contamination. Special conditions for slaughter include reduced line speed, increased space between animals and increased use of workstation hygiene facilities. Since their introduction in Ireland, cattle regulations have become more stringent and at present, both category 4 and 5 animals are rejected. However, a procedure for shaving accumulated hardened faeces (faecal clods) from category 4 and 5 animals has been introduced into most abattoirs, enabling them to reach the cleanliness standard. The potential risk of pathogens surviving in faecal clods on the hide of animals at slaughter is not known. This study examined: 1. The relationship between livestock cleanliness categories and the amount of contamination on the resultant carcasses. 2. The difference in bacterial contamination on carcasses from category 4 animals dressed without increased use of workstation hygiene facilities and those dressed with increased use of hygiene facilities. 3. The survival of E. coli O157:H7 in faecal clods
