The temperature in a refrigerator should be maintained at or below 40 F, and food should be stored in covered containers. Heat kills bacteria. Pasteurized eggs should be used in place of shell eggs when making homemade ice cream, eggnog and mayonnaise. If you cannot obtain pasteurized eggs, then you must omit the egg ingredient when making homemade ice cream. When cooking eggs, make sure that the yolk and white are firm, not runny.
Microwave cooking requires special precautions.
Many microwave dishes must be removed from the oven and stirred to ensure thorough cooking. Always heat pre-cooked foods or leftovers thoroughly, whether in a microwave or conventional oven. Chronically ill persons need to avoid the same foods in restaurants that they would at home. A good way to determine doneness is to cut into the center of a steak, hamburger or other piece of meat. If it is the least bit pink or bloody, it needs more cooking.
