Safe Microwave Defrosting, Cooking and Reheating of Food

Thaw food using the defrost button on your microwave.

  • Remove food from packaging before defrosting. Do not use foam trays and plastic wraps because they are not heat stable at high temperatures.
  • Cook meat, poultry, egg casseroles and fish immediately after defrosting in the microwave oven. During defrosting in the microwave, food heats up and can cause bacteria that may be present to start multiplying.
  • Cover foods with a lid or a microwave-safe plastic wrap to hold in moisture and provide safe, even heating.
  • After reheating foods in the microwave oven, allow the food to "stand." Then, use a clean food thermometer to check that food has reached 165°F.

Microwave-Safe Containers & Wraps

Only use cookware that is specially manufactured for use in the microwave oven. Glass, ceramic containers and all plastics should be labeled for microwave oven use.
