Foods such as cereals, rice, pasta and spices may seem benign when it comes to foodborne illness, but if these foods are cooled slowly without refrigeration, they can become prime targets for Bacillus cereus, a pathogen that forms heat-resistant spores and can lead to diarrhea or vomiting. The bacteria are found in soil and in foods that grow close to the ground. As the Food Safety Information Council reports, starchy vegetables, meat products, grain-based foods, sauces, puddings and spices are all culprits. While the spores Bacillus cereus produces are dormant, they can multiply when exposed to warmth and moisture. Cooking or reheating the food will not destroy the toxin, so to help prevent it, store cooked foods in shallow containers and refrigerate them promptly, don’t let frozen foods thaw at room temperature, and make sure any precooked foods are stored in the refrigerator for a maximum of two or three days.
