Biofilms are microbial communities attached to surfaces that are transferred by cross contamination when direct contact between food, surfaces and utensils takes place (1). They are of interest for public health and for the food industry because they are formed by both non-pathogenic and pathogenic environmental bacteria (1) (23) and they have the ability to survive food processing stresses, such as disinfection (2). These pathogenic microorganisms such as E. coli, Listeria monocytogenes and Salmonella, as well as their serotypes, produce biofilms, occurring more frequently in meats (1) (2) due to the organic residues which provides the adequate conditions for its growth, causing the reduction of food shelf life (2) and foodborne infections (3). Due to its transfer form, cross contamination can happen at any time during the production line (1) (2) especially at critical points such as filling, cutting, marinating and curing stages (22), as pointed out by Wagner and collaborators (23), which represent microbiological, chemical and physical hazards for food (19). Studies carried out on the aforementioned biofilm-producing pathogens in the chicken samples in the United States (6), Brazil (15) and China (9) show their 3 prevalence in the product, even after disinfection. Peru was ranked as one of the largest chicken consumers in Latin America in 2018 (18) and, seeing the growing demand of the consumers, it is necessary to control the formation of biofilms to avoid the contamination of these chicken meat products. Furthermore, the low resources and poor sanitation of the developing countries (3) in production plants opens the possibility of greater sanitary consequences in the future. It is really challenging to follow the trace of the origin of the contamination given that it is spread by direct contact, so it is not possible to determine any spatial or temporal pattern that may be associated with failures in the control of the product’s processing. Therefore, it is suggested to obtain samples for microbiological control during the process’s stages through conventional or molecular tests to compare the strains and establish their origin (22) (21) (1). In addition, a continuous effort is necessary to investigate the origin of these bacteria and their incidence in chicken meat contamination in production plants (1). Consequently, this work proposes to determine the efficacy of the disinfection method at critical points associated with biofilms formation in the chicken meat processing chain.
