SUMMARY:
Food contamination by enterotoxigenic strains of Staphylococcus spp. it is common because they naturally inhabit the human airways and are isolated from several animals, mainly dairy animals. Species of the genus can produce enterotoxins, causing staphylococcal food poisoning, which despite the underreporting caused by the short duration of clinical symptoms, is one of the most common Foodborne Diseases (DTA) in the world. This systematic review aimed to gather information from existing studies around the world on the investigation of staphylococcal enterotoxin (SE) in foods, systematize the results through meta-analysis and answer the question: What is the worldwide prevalence of staphylococcal enterotoxins in foods contaminated by Staphylococcus spp.? The systematic review followed the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) and the protocol was registered in PROSPERO (CRD42021258223). Eligibility criteria were defined based on PECOS (Population - primary studies reporting analysis of SE in foods, Exposure - foods exposed to Staphylococcus spp, Comparator - not applicable, Outcomes - primary: identification of SE in food and secondary: types of toxins and the foods involved, and Study Types - primary cross-sectional studies). The searches were carried out in the following databases: Medline, GALE, Science Direct, CAB Direct, and Google Scholar, in addition to a manual search in the reference list of articles, theses and dissertations directory, and country health agencies. Primary cross-sectional studies published in the last twenty years and without language restriction were selected, which reported the investigation of staphylococcal enterotoxins in foods naturally contaminated by Staphylococcus spp. The risk of bias in the inserted studies was evaluated by the tool developed by the Joanna Briggs Institute for prevalence studies. All steps were performed by two independent researchers, and a third was responsible for conflict resolution. A total of 2382 articles were retrieved and exported to the Rayyan Intelligent Systematic Review application, which was used to select studies in different phases. After applying the eligibility criteria, 35 studies were included in the review and meta-analysis. Three food groups were formed: 1- dairy products, 2- meat products and 3- other foods. In the latter, mixed foods and other less mentioned foods were included. In the meta-analysis, group 1 had the highest number of samples and the prevalence of positive samples was 18.7% (95%, CI 7.41-31.94; p<0.01, I2= 97%). in group 2 the prevalence was 1.78% (95%, CI 0.0-16.7; p<0.01, I2= 97%) and in group 3 it was 27.1% (95%, CI 0, 24-67.53, p<0.01, I2=97%). The results showed a high prevalence of enterotoxin in foods contaminated by Staphylococcus spp. and that the food group with the highest prevalence was group 3. Only 40% (n=14) of the studies cited the type of toxin found, most of which are classic enterotoxins (SEA to SEE). It is necessary to carry out more studies with the analysis of the enterotoxin, to broaden the general perception of the risks to food safety, contribute to the study of the epidemiological profile and guide the efforts of health agencies for the development of preventive measures related to the Good Practices of Food Manufacturing and Handling.
