Abstract
ABSTRACTOur objective was to determine the effect of acetic acid (AA) and temperature in inhibiting Salmonella typhimurium, aerobic plate counts (APCs) and total coliforms on pork cheek meat. Compared with initial APCs of control cheeks, a reduction in log10 CFU/cm2 APC by more than 78.6% was found in all samples that were treated with 20 and 40° acetic acid (P < 0.05). Additionally, total coliforms for acidtreated cheeks were lower for both AA treatments (P < 0.05). Cheeks (n = 10/treatment) were also sprayed in a commercial pork slaughter facility carcass wash with 2% AA (25°) and compared to control (non‐treated) cheeks. The incidence of Salmonella decreased by 67% for acid‐treated cheeks (P < 0.05). A significant decrease in APCs and coliforms occurred for the acid‐treated cheeks (P < 0.05).
