Abstract: Microbial contamination on beef carcasses was evaluated in a small-scale meat processing facility that was utilizing an organic acid wash system to minimize carcass contamination. Treatments were evaluated as a function of time in the process for aerobic plate count, lactic acid producing microbes, total coliforms and generic Escherichia coli. Treatments were, prior to the wash system, immediately after the wash and 24 h after the wash at-2 �C . Significant differences were observed between treatments for each class of microorganism. Sampling location (rump, fore shank and brisket) on the carcass was also evaluated and found to have a significant difference between locations ( = 0.05). Results indicated significant reductions in beef carcass contaminants could be achieved through the carcass washing system being evaluated. Significant reduction of E. coli and total coliforms after the carcass wash was not observed due to the already low counts observed as a result of the wash itself.
