大肠埃希菌O157：H7、沙门氏菌、非O157大肠杆菌季节性流行。大肠杆菌（STEC），和携带stx的细胞在三个中西部饲料牛肉加工厂进行了监测。总的来说，E。大肠杆菌O157：H7从5.9%的粪便样品、60.6%的兽皮样品和26.7%的屠体中回收。该病原体也从1.2%（1，232例中的15例）的冷冻（干预后）取样尸体中回收，
The seasonal prevalence of Escherichia coli O157:H7, Salmonella, non-O157 E. coli (STEC), and stx-harboring cells was monitored at three Midwestern fed-beef processing plants. Overall, E. coli O157:H7 was recovered from 5.9% of fecal samples, 60.6% of hide samples, and 26.7% of carcasses sampled before the preevisceration wash. This pathogen also was recovered from 1.2% (15 of 1,232) of carcasses sampled at chilling (postintervention) at approximate levels of
