S. aureus cells are relatively more resistant than many gram negative food spoilage organisms. Human intoxication is caused by ingesting enterotoxins produced in food by strains of S. aureus, usually because the food has not been kept hot enough (60ºC, or above) or cold enough (7.2ºC, or below). In frozen foods they may survive even at -10ºC. In general, survival of S. aureus is best in foods that contain high concentration of sugars, eggs and buffering component such as phosphates and protein.
