Turkey broiler carcases surface microbiocenosis after their treatment with peracetic acid

When using the method of airborne irrigation with a solution of PA-15 (0.02 %), the maximum indicator of QMAFAnM (9.2 ± 0.21×103) on the surface of broiler turkey carcasses was observed when using peracetic acid at a concentration of 0.02 % by immersion in water, the solution was exposed to 15 min, while the minimum (3.7 ± 0.07×10) was recorded with the airborne method of using the solution at a concentration of 0.06 %. When processing turkey carcasses for 15 minutes at a solution concentration of 0.06 %, microorganisms of the genus Salmonella and L. monocytogenes were absent. The minimum index of contamination of the surface of broiler turkey carcasses NMAFAM was recorded at a concentration of 0.06 % of the PA-15 preparation and an exposure of 20 minutes after treatment with airborne irrigation and in an aqueous solution. With an exposure of 25 minutes, the smallest amount of NMAFAM is observed with airborne irrigation and treatment with a 0.06 % aqueous solution of the PA-15 preparation. At a drug concentration of 0.04 % on the surface of carcasses with airborne irrigation, the smallest amount of NMAFAM is detected and microorganisms of the species L. monocytogenes and salmonella are not detected. At a concentration of the working solution PA-15 of 0.06 %, discoloration of the surface tissues of the carcasses was observed. The drug based on peracetic acid PA-15, both with airborne and water treatment, reduces the content of pathogenic and opportunistic microflora on the surface of broiler turkey carcasses at the tested concentrations (0.02 %; 0.04; 0, 06 %). The best bactericidal effect is achieved when processing carcasses with airborne irrigation at a working solution concentration of 0.04 % and exposure for 25 minutes. The specified parameters of the drug use do not have a negative effect on the quality indicators of turkey meat.
