RESUMO:

Salmonella spp. it is one of the most widespread pathogens in nature, with man and animals being its main natural reservoirs, besides being considered as one of the main agents involved in food outbreaks worldwide. The incidence of this bacterium motivated by contaminated food shows that, today, despite the technological advances observed, this problem still occurs worldwide. Cattle are one of the main responsible for the dissemination of this pathogenic agent as well as the entire productive chain that involves the production and processing of its products. Certainly, milk and dairy products are among the main foods correlated with cases of foodborne diseases both in Brazil and in several other countries. Depending on the Salmonella serotype involved in the food outbreak, it can cause two main forms of the disease, such as salmonellosis and enteric fever. Both causing gastrointestinal disturbances with enteric fever being the most serious form of the infection. However, the occurrence of these diseases is still quite underreported, especially at the national level. The objective of this work was to prepare a study on the occurrence of Salmonella at the state, national and international levels. In addition to conducting microbiological analysis for Salmonella ssp. in 302 samples of milk and its derivatives sent to the Laboratory of Inspection and Technology of Milk and Derivatives of the Federal University of Bahia between the period of March 2019 to March 2020. These products come from several municipalities in the State of Bahia, Brazil. The ISO 6579: 2002 methodology applied to microbiological research on Salmonella spp. did not detect the presence of this pathogen in any of the samples analyzed in the study. Although, the study did not reveal the presence of Salmonella spp. in none of the dairy products analyzed in Bahia, the risk of ingesting these products should be considered, given the severity of the diseases caused by the bacteria in question. Some factors such as wide distribution of Salmonella spp. among animals, permanence in the environment and in food, as well as the existence of asymptomatic carriers in both animals and man, contribute for this microorganism to assume a role of great relevance in world public health, therefore, permanent control programs must be adopted.
