Microbiological safety of food: development of normative and methodical base

Abstract

The main results and prospects of fundamental and applied hygienic research of the laboratory of biosafety and nutrimicrobiome analysis of the Federal Research Centre of Nutrition, Biotechnology and Food Safety (hereinafter - the Institute of Nutrition) in the direction of developing a regulatory and methodological framework for assessing the microbiological safety of food are reviewed. The formation of microbiological regulation as a scientific analytical and administrative managerial process in the former USSR and the Russian Federation is considered in the context of historical data, including personal contribution of the scientists of the Institute of Nutrition and other specialists. The basic principles of regulation are emphasized: the scientific validity of the established criteria and requirements, the feasibility, technological attainability, differentiation according to the degree of danger to the health of consumers, preventive nature. The resource of the national normative and methodological base in the field of microbiological food safety at the turn of the century is characterized, the features of the introduction of the microbiological risk assessment (MRA) methodology in the substantiation of Russian norms and measures for the prevention of food infections are described. The information is given on the developed guidance documents on MRA and on the examples of norms adopted on its basis. The article covers the issues of reglamentation the requirements for food safety and reducing the spread of new pathogens Stx-Escherichia coli, Listeria monocytogenes, Enterobacter sakazakii, Campylobacter spp. in the food chain based on risk-oriented approaches. The necessity of taking specific measures for the prevention of cross-contamination in the poultry processing industry is substantiated, taking into account the evidence of the high adaptability of C. jejuni isolated from domestic raw poultry. In the sanitarian-mycological aspect, the monitoring perspective of mould fungi, taking into account their chemotypes, in cereals and non-grain plant products is shown to predict the risk of mycotoxin accumulation and take timely measures. The need to assess the impact on the population, taking into account the characteristics of consumption in the country, as well as the development of criteria for indirect risk of residues are argued for regulation of the antibiotics in food. In light of the challenges in the field of agro- and food technologies to public health at the present stage, contributing to the acceleration of microbial evolution and the emergence of new risks in food, the priority tasks of improving the regulatory and methodological base for assessing microbiological safety have been identified, with an emphasis on the introduction into the process of substantiating the norms of innovative OMICs-technologies based on the achievements of genomics, transcriptomics, proteomics, metabolomics, bioinformatics.
