To determine the prevalence and level of E. coli O157:H7 and Salmonella on hides and pre-evisceration carcasses in small beef processing plants.
Approach: We will collect hide and preevisceration carcass samples from seven small (<1000/d) processing plants. Samples will be obtained from each plant on three consecutive days. These samples will be tested for the prevalence and level of E. coli O157:H7 and Salmonella.
