Campylobacter spp. → positive → beef carcasses
prevalence: 1.5% of 1022 samples
“For beef carcasses, positive tests were obtained for 1.5% of 1022 samples tested for Campylobacter spp.”
E. coli O157:H7 → are primary reservoirs → dairy and beef cattle
“Epidemiological investigations demonstrate that dairy and beef cattle are primary reservoirs of this organism, carrying it asymptomatically and shedding it intermittently and seasonally in their feces.”
Escherichia coli O157 → isolated from → 1.5% of samples of beef products
year: 1996location: Sheffield
“During surveillance in 1996, E. coli O157 was isolated from 5.9% of samples of lamb products and from 1.5% of samples of beef products, despite the prevalence in cattle being much higher than in sheep.”
Shiga toxin (verocytotoxin)-producing Escherichia coli (STEC) → contaminates → minced beef
location: Lugo, Spaintime_period: 1995-2003
“Thus, our data confirm minced beef in the city of Lugo as vehicles of highly pathogenic STEC.”

“Vero cytotoxin (VT)-producing Escherichia coli O157 (O157 VTEC) were isolated from a raw beefburger obtained from a retail source linked to a small community outbreak of O157 VTEC infection in Wales.”
coliform bacteria → isolated → beef and pork carcasses

“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”
