How to prevent Bacteria and Foodborne Illness?

Most cases of foodborne illnesses can be prevented through proper cooking or processing of food, which kills bacteria. In addition, because bacteria multiply rapidly between 40°F and 140°F, food must be kept out of this temperature range.

Follow these tips to prevent harmful bacteria from growing in food:

  • Refrigerate foods promptly. If prepared food stands at room temperature for more than 2 hours, it may not be safe to eat. Set your refrigerator at 40°F or lower and your freezer at 0°F.
  • Cook food to the appropriate internal temperature—145°F for roasts, steaks, and chops of beef, veal, and lamb; 160°F for pork, ground veal, and ground beef; 165°F for ground poultry; and 180°F for whole poultry. Use a meat thermometer to be sure. Foods are properly cooked only when they are heated long enough and at a high enough temperature to kill the harmful bacteria that cause illnesses.
  • Prevent cross-contamination. Bacteria can spread from one food product to another throughout the kitchen and can get onto cutting boards, knives, sponges, and countertops. Keep raw meat, poultry, seafood, and their juices away from all ready-to-eat foods.
  • Handle food properly. Always wash your hands for at least 20 seconds with warm, soapy water before and after handling raw meat, poultry, fish, shellfish, produce, or eggs. Wash your hands after using the bathroom, changing diapers, or touching animals.
  • Wash utensils and surfaces before and after use with hot, soapy water. Better still, sanitize them with diluted bleach—1 teaspoon of bleach to 1 quart of hot water.
  • Wash sponges and dish towels weekly in hot water in the washing machine.
  • Keep cold food cold and hot food hot.
  • Maintain hot cooked food at 140°F or higher.
  • Reheat cooked food to at least 165°F.
  • Refrigerate or freeze perishables, produce, prepared food, and leftovers within 2 hours.
  • Never defrost food on the kitchen counter. Use the refrigerator, cold running water, or the microwave oven.
  • Never let food marinate at room temperature—refrigerate it.
  • Divide large amounts of leftovers into small, shallow containers for quick cooling in the refrigerator.
  • Remove the stuffing from poultry and other meats immediately and refrigerate it in a separate container.
  • Wash all unpackaged fruits and vegetables, and those packaged and not marked “pre-washed,” under running water just before eating, cutting, or cooking. Scrub firm produce such as melons and cucumbers with a clean produce brush. Dry all produce with a paper towel to further reduce any possible bacteria.
  • Do not pack the refrigerator. Cool air must circulate to keep food safe.
