Abstract

Shiga toxin–producing Escherichia coli (STEC) and Salmonella are foodborne pathogens commonly harbored in the gastrointestinal tract of sheep. These pathogens can be on the hide of sheep and transferred to the carcass, causing a foodborne hazard. Salmonella can also be found in the lymph nodes of sheep, creating a biological hazard during harvest and processing. Developing countries lack baseline data on the presence of these foodborne pathogens on meat products, specifically sheep meat. Therefore, the objective of this study was to evaluate the presence of STEC and Salmonella on sheep hides, preevisceration carcasses, and final carcasses and Salmonella in subiliac lymph nodes from two small Honduran harvest facilities, plants A and B. Sponge swabs from the foreshank region of hides and carcasses and subiliac lymph node samples were collected from 96 sheep (86 at plant A; 10 at plant B). Microbial detection of STEC and Salmonella was performed by using the BAX System to screen for pre
