Interpretive Summary:

Technical Abstract: Peracetic acid (PAA) in poultry processing is variable. Anecdotal evidence suggests PeraClean may be more stable than other companies; however, the effects varying stability has on pathogen and microbial reduction are unknown. This is important as stability may enable the PAA to be more effective for longer periods of time. In order to evaluate the antimicrobial effects of PAA, one PAA (PeraClean; P) was qualitatively compared against two competitor products (Competitors 1 and 2; C1 and C2) at the University of Arkansas Pilot Processing Plant. A total of 150 Ross 708 broilers (42 d) were used in the current study (n=10 per treatment group). Prior to treatment, 10 birds were sampled post-evisceration to evaluate the incoming microbial load on the birds (C). The birds were dipped in either 400 ppm or 600 ppm PAA (A or B), chilled in either 25 ppm or 45 ppm PAA (1 or 2), and then manually agitated in 400 mL of nBPW for 1 min. There were 10 birds per treatment group in total. The resulting rinsates were transported to the Center for Food Safety and assessed for total microbiological load with total aerobic plate counts (Trypticase Soy Agar; APC), coliforms, (Eosin Methylene Blue Media; EMB), Salmonella (Xylose Lysine Deoxycholate agar, XLD), and Campylobacter (modified Charcoal Cefoperazone Deoxycholate Agar, mCCDA). The microbiological plates were incubated as per manufacturer’s directions. Statistical analyses were calculated in JMP 14.0, with a significance level of p less than or equal to 0.05. Data indicate that all three sources of PAA are effective sanitizers for poultry processing, but each product qualitatively resulted in differences in prevalence and load. PA1 had the most effective antimicrobial inclusion rate for PeraClean, effectively reducing Campylobacter prevalence 100%, with load differences in Coliforms (1 log10), Salmonella (0.8 log10), and Campylobacter (2.58 log10). Yet, other products were mostly effective on Campylobacter at different antimicrobial inclusion rates. Additional studies will be required to determine if those differences are quantitatively significant and whether the product effects are due to stability.
