Action of "DEZON NUK-5" preparation on microflora of bird carcass surfaces

There is a serious problem in the production of poultry meat - the potential probability of its exogenous seeding by pathogenic microorganisms - causative agents of food infections, toxicoinfections and toxicosis. These are Escherichia, Salmonella, Staphylococcus, Campylobacter and other bacteria. Disinfection in cooling baths should ensure the destruction of such microorganisms on the surface of carcasses and prevent the threat of contamination of consumers of poultry products. Purpose of the work: to determine the effectiveness of the use of the disinfectant "DEZON NUK 15" in cooling baths for surface treatment of chicken and turkey carcasses after slaughter and evisceration. To study the bactericidal action of the prepared solutions, we used models - poultry products of broilers and turkeys (chilled wings) with good organoleptic characteristics. The models were contaminated with cultures of sanitary indicative and pathogenic bacteria: Staphylococcus aureus, Escherichia coli, Salmonella Enteritidis, Campylobacter jejuni, Bacillus subtilis. Contaminated models were kept in working solutions of a disinfectant with a concentration of 0.025%, 0.050%, and 0.100% according to NUK. After an exposure of 10, 25 and 40 minutes, inoculations were made on nutrient media from the surface of the models and incubated under optimal conditions. Found that the drug "DEZON NUK-15" has bactericidal activity against the tested working cultures of bacteria. After contamination with the tested cultures of bacteria, the surface of poultry products of chickens and turkeys is disinfected with a solution of the drug "DEZON NUK-15" with a concentration of 0.050% and 0.100% for 25-40 minutes. No changes or deterioration in the organoleptic characteristics of poultry products was observed. The bactericidal effect of the drug is practically the same in relation to poultry products of chickens and turkeys.
