Buy safe food

Follow these tips to make sure the food you bring home from the grocery store is safe to eat.

  • Buy cold foods last during your shopping trip.
  • Don’t buy food if the package is torn or leaking.
  • Don’t buy food past its "sell–by" date.
  • Keep raw meat and poultry separate from other food.
  • Don’t buy canned goods that are bulging, dented or rusted.

Prepare food safely

  • Take steps during the preparation process to reduce the risk of poisoning.
  • Wash hands in hot, soapy water before, during and after food preparation.
  • Wash all fruits and vegetables before eating.
  • Wash cutting boards and utensils in hot, soapy water or a 10% bleach solution after use.
  • Thoroughly cook all meats, poultry and seafood.
  • Use a meat thermometer, rather than relying on how meat looks. Cook to these temperatures:
    • Ground meats: 160°F
    • Ground poultry: 165°F
    • Beef, veal, lamb steaks, roasts and chops: 145°F
    • Fresh pork: 160°F.
    • Whole poultry: 180°F for thighs; 170°F for breasts
  • Keep raw meat, poultry, fish and their juices away from other food.
  • Don’t eat raw or partially cooked eggs or shellfish.
  • Cook foods as close to serving time as possible.
  • Marinate meats and poultry in the refrigerator.
  • Eat cooked leftovers within 4 days.
