Abstract

In 2006 and 2007 beef and pork carcass swabs from provincially inspected abattoirs in Alberta, Canada were tested to determine the levels of total aerobic bacteria, coliform bacteria, and generic Escherichia coli, and the prevalence of Salmonella spp., Campylobacter spp., and Shiga toxin-producing E. coli (STEC). Swabs from beef and pork carcasses from 48 and 34 facilities, respectively, were analyzed. All samples tested were positive for aerobic bacteria with 99.8% of beef and 96.0% of pork samples, having total counts of ≤ 100 000 CFU/cm(2). Coliform bacteria were isolated from 22.4% and 42.0% of beef and pork carcass samples, respectively. Generic E. coli were recovered from 14.6% of beef and 33.7% of pork carcass samples. For beef carcasses, positive tests were obtained for 0.1% of 1036 samples tested for Salmonella spp., 1.5% of 1022 samples tested for Campylobacter spp. and 5.4% of 1018 samples tested for STEC. For pork carcasses, positive tests were obtained for 1.6 % of 1076 samples tested for Salmonella spp., 8.8% of 1070 samples tested for Campylobacter spp. and 4.8% of 1067 samples tested for STEC.
