Interventions to reduce microbiological contamination of beef variety meats.

Hot water and solutions of acetic acid, lactic acid, or trisodium phosphate applied by immersion or spraying, chlorine solution applied by immersion, and exposure to steam in a pasteurization system, in a cabinet, or in combination with vacuum were evaluated for their effectiveness in reducing levels of bacterial contamination on samples of beef cheek meat, large intestine, lips, liver, oxtail, and tongue. Treated samples (five per treatment) and controls were analyzed for aerobic plate counts (APCs) on tryptic soy agar and for total coliform counts (TCCs) and Escherichia coli counts (ECCs) on Petrifilm. Acetic acid (2%) immersion and trisodium phosphate (12%) spraying and immersion for 10 s were among the most effective treatments in 16, 15, and 14, respectively, of 18 comparisons for reducing APCs, TCCs, and ECCs on four or more of the six variety meats tested. Acetic acid (2%) spraying, lactic acid (2%) immersion, and hot water (78 to 80 degrees C) spraying for 10 s were among the most effective treatments for reducing APCs, TCCs, and ECCs on four or more of the six variety meats. Chlorine (0.005%) immersion and steam were among the least effective treatments for reducing APCs, TCCs, and ECCs on variety meats. The results indicated that interventions applied to decontaminate beef carcasses can also be considered for decontamination of variety meats.
