Salmonella spp. and Campylobacter spp. continue to be prominent food safety concerns for the poultry industry and consumers alike. Peracetic acid (PAA) has been approved as an antimicrobial for use in poultry chillers. To validate its effectiveness, 100 poultry carcasses (per replication x 2) were inoculated with Salmonella (10(6) cfu) or Campylobacter (10(6) cfu) and were randomly allocated into chill water containing chlorine (0.003%) or PAA (0.0025%, 0.01%, or 0.02%). Results indicated that PAA concentrations as low as 0.0025% were effective in decreasing Salmonella spp., whereas PAA levels of 0.02% were effective in decreasing Campylobacter spp. when compared with the chlorine treatment. A sensory study was also conducted with another set of 500 carcasses (not inoculated). Birds were treated with water, chlorine (0.003%), or PAA (0.01%, 0.015%, or 0.02%). Sensory panels and microbial data were collected weekly on randomly sampled carcasses that were stored at 4 degrees C for 21 d. The PAA-treated carcasses at 0.015% and 0.02% had an extended shelf-life compared with those treated with water or chlorine. Specifically, on d 15, the only treatments that could be served to sensory panelists were the carcasses treated with 0.015% or 0.02% PAA. The carcasses treated with water, chlorine, or 0.01% PAA had off-colors, off-odors, and high microbial counts. These results suggest that PAA may be an effective antimicrobial when used in poultry chiller applications and greater levels (>or=0.015%) may extend product shelf-life.
