Antibiotics have traditionally been used to prevent and treat common diseases in farm animals. However, residual antibiotics in dairy products and meat remain a serious public health problem, which is associated with antibiotic resistance. The research objective was to assess the impact of antibiotic contamination on the quality and safety of dairy products, the microbiological composition of milk, and antibiotic-resistant bacteria. The study featured six years of Russian and foreign scientific articles registered in PubMed (National Center for Biotechnology Information, USA), Scopus and ScienceDirect (Elsevier, the Netherlands), Web of Science (Clarivate, USA), and eLibrary.ru. The analysis involved 63 foreign and domestic sources. Residual antibiotics in milk inhibits the vital activity of lactic acid bacteria, which, in its turn, disrupts the technological process of yogurts, cheeses, etc. After such processing as normalization, pasteurization, and homogenization, antibiotics accumulate in fermented dairy products and bind with milk proteins and fats. Antibiotics, in their initial amount, enter yoghurts from dairy raw materials. In cheese production, antibiotics usually pass into the whey, but aminoglycosides, quinolones, and tetracyclines remain in the finished product because they bind with the protein fraction. The problem of biological safety of dairy products is associated with antibiotic resistance developed by human intestinal microbiota. This problem remains understudied, and the number of scientific papers on the matter is limited.
