Veterinary and sanitary measures are one of the components of the technological process at food and meat processing plants, aimed at preventing the occurrence and spread of infection from primary processing to finished products. The objective of this study was to provide a sanitary and bacteriological assessment and experimentally study the bactericidal activity of «Biolok» for disinfecting surfaces and process equipment in sausage production facilities. Scientific novelty is a fundamental aspect of introducing a new disinfectant into meat production and processing facilities. It must meet all legal veterinary and sanitary requirements and be safe, both as food raw materials and as food products. Based on the results of production trials, a concept and recommendations for preventive disinfection regimens and methods were formulated. During the trials, disinfection of the treated objects was carried out using a wet method, using fine-droplet irrigation, at a relatively low solution flow rate (0.2-0.5 l/m2). A fundamental aspect and underlying criterion for introducing a new disinfectant into meat production and processing facilities is its compliance with all established veterinary and sanitary requirements and safety at all stages – from food raw materials to finished food products. The results of sanitary production trials of the product at a meat processing facility, in sausage production facilities, demonstrated high bactericidal efficacy. Studies have shown that «Biolok» effectively disinfects smooth surfaces with a 1.0% solution at a rate of 0.25-0.3 l/m² with a 3-hour exposure time, and rough surfaces with a 4.0% solution at a rate of 0.5 l/m² with a 3-hour exposure time, when current regulations require disinfection quality control for the isolation of coliform bacteria and staphylococci. The tested product demonstrated satisfactory results in terms of microbiological purity in meat processing facilities and can be recommended for sanitary and industrial measures in production facilities to ensure microbiological purity, with quality control for the isolation of E. coli and St. aureus .
