Research Note: Lactic Acid and Trisodium Phosphate Treatment of Lamb Breast To Reduce Bacterial Contamination

摘要

Lactic acid and trisodium phosphate (TSP) were evaluated for the ability to reduce Escherichia coli and aerobic plate counts (APCs) on lamb breasts than were inoculated with a lamb fecal paste. A 90-s water rinse was applied followed by either a 9-s (55 deg. C) 2/100 lactic acid spray, a 60-s (55 deg. C) 12/100 TSP dip, or a combined treatment of both lactic acid and TSP treatments. Lactic acid reduced E. coli and APCs by 1.6 log_10cm~2, and TSP caused a 1.8-log_10/cm~2 reduction in E. coli and a 0.7-log_10/cm~2 reduction in APCs.
