In February and May of 1999, the sanitary services of the Health Board in the cities of Manhuaçu and Passa-Quatro, Minas Gerais, Brazil, were notified of two food poisoning outbreaks involving a total of 378 individuals. In the first outbreak, 50 individuals became ill after eating Minas cheese. The symptoms of food poisoning (diarrhoea, vomiting, dizziness, chills, and headaches) appeared within 2 h of the individuals ingesting the cheese. The second outbreak affected 328 individuals, who presented with symptoms of diarrhoea and vomiting after consuming raw milk. Samples of the cheese and raw milk were collected. The analysis of the cheese and unpasteurized milk in outbreak one showed that Staphylococcus aureus was present at 2·4×103 – > 2·0×108 cfu g−1 and had produced the enterotoxins SEA, SEB, and SEC. The analysis of the raw milk in outbreak two indicated the presence of coagulase-negative staphylococci in counts exceeding 2·0×108 cfu g−1 and the production of enterotoxins SEC and SED. The specific enterotoxins found in each of the two outbreaks implicate the source of contamination in the first out break to be the food handlers and for the second case cattle mastitis.
