Technical Abstract: Campylobacter is a major concern for poultry processors, as USDA performance standards have become stricter. This study evaluated CMS PoultrypHresh™, a low pH processing aid, and peracetic acid using consecutive and sequential dip treatments to reduce Campylobacter in thighs. Thighs (n=3/treatment group) were inoculated with a C. coli marker strain (108) and each dipped into bags containing 1 L of treatment 1 for 6 s. Thighs were allowed 5 s to drip, placed onto foil for 60 s, and dipped into treatment 2 for 6 s. After 5 s drip time, each was placed in a bag with 150 mL buffered peptone water and hand shaken for 60 s; controls same procedure, no treatment. Rinsates were serially diluted, plated onto Campy Cefex agar with 200 ppm gentamicin and incubated microaerobically for 48 h at 42°C. Procedures were replicated 5 times. Significant reductions (P<0.05) compared to untreated using consecutive dips of PoultrypHresh™ and PAA were 98.2% and 99.3%, respectively. Treatments of PoultrypHresh™ then peracetic acid reduced Campylobacter 99.2% from untreated thighs. Peracetic acid then PoultrypHresh™ showed significant reductions compared to all other treatments (99.9% from untreated). This data suggests that treatment with an oxidizing agent (PAA) following by an acidic treatment maximizes Campylobacter reduction. Treating with this sequence may allow processors to meet the strict performance standards on Campylobacter in broiler parts.
