Fate of Escherichia coli O157:H7, Salmonella Typhimurium DT 104, and Listeria monocytogenes in Fresh Meat Decontamination fluids at 4 and 10 deg. C

摘要

Bacterial pathogens may colonize meat plants and increase food safety risks following survival, stress hardening, or proliferation in meat decontamination fluids (washings). The objective of this study was to evaluate the ability of Escherichia coli O157:H7, Salmonella Typhimurium DT 104, and Listeria monocytogenes to survive or grow in spray-washing fluids from fresh beef top rounds sprayed with water (10 or 85 deg. C) or acid solutions (2 /100 lactic or acetic acid, 55 deg. C) during storage of the washings at 4 or 10 deg. C in air to simulate plant conditions.
