These bacteria are found on the skin, in the nose, mouth, and throat of many healthy people. These bacteria sometimes cause skin infections, such as acne or boils. You can get staphylococcal food poisoning by eating food contaminated with staphylococcal bacteria. Food is usually contaminated when someone handles food with bare hands, especially after touching the face or mouth. If the food is not cooked thoroughly or properly kept hot or cold, the bacteria can grow and produce toxin in the food.
Foods commonly involved include ham, poultry, filled pastries, custard, egg salad and potato salad.
The illness goes away on its own, usually within a day. See your doctor. The illness is usually diagnosed by symptoms and quick onset, but your doctor may order tests to rule out other conditions. There is no medicine to cure staphylococcal food poisoning. Drinking lots of fluids helps your body replace fluids lost by diarrhea and vomiting.
