Current USDA reprocessing procedures were evaluated in five commercial broiler processing facilities. Reprocessing procedures included a carcass wash/rinse in 20 ppm chlorine at a USDA approved reprocessing station. Results suggest that in most plants current reprocessing procedures are microbiologically justified; however, there does appear to be some plant variation regarding the effectiveness of these procedures. In four of five plants total plate counts, Coliform levels, and E. coli counts were significantly lower on the reprocessed prechill carcasses compared to inspection-passed carcasses. There was no difference in incidence of Salmonella spp. (P=0.18) or Campylobacter jejuni/coli (P=0.57) between the two groups of carcasses. However, in two of the five plants reprocessed carcasses had higher levels of Salmonella spp. than did inspection-passed carcasses. Levels of C. jejuni/coli were either not affected or were significantly lower on the reprocessed carcasses.

Key Words: Campylobacter • reprocessing • Salmonella • broilers
