Microbiological evaluation of pork offal products collected from processing facilities in a major United States pork-producing region

摘要

Analysis of 370 offal samples from 15 US pork-processing facilities detected Yersinia enterocolitica-positive (2.4%) and Salmonella positive (21.8%) samples and mesophilic aerobic plate counts & 10(7) colony-forming units/g (3.2%). A risk assessment showed intestine (20%), brain (21%), liver and heart (73%), and kidney (87%) sampling batches were acceptable for human consumption.
