Food Safety Basics

Safe minimum internal temperatures from USDA, plus clean, separate, cook and chill: the habits the recipes here rely on.

Safe minimum internal temperatures

Color is not a reliable sign of doneness. Use a food thermometer in the thickest part of the food, away from bone, fat and gristle.

FoodCook toRest
Beef, pork, veal and lamb steaks, chops and roasts145°Fat least 3 minutes
Ground meats (beef, pork, veal, lamb)160°F
Ham, fresh or smoked (uncooked)145°Fat least 3 minutes
Fully cooked ham, to reheat140°F if packaged in a USDA-inspected plant; 165°F for all others
All poultry (breasts, whole birds, legs, thighs, wings, ground poultry, giblets, stuffing)165°F
Eggs and egg dishes160°F
Fish and shellfish145°F

Clean, separate, cook, chill

  • Clean: wash your hands with plain soap and water for at least 20 seconds, including the backs, between the fingers and under the nails. Wash utensils and counters often.
  • Separate: use one cutting board for produce and foods eaten raw, and another for raw meat, poultry and seafood. Do not rinse raw meat, poultry, eggs or seafood; it spreads germs.
  • Cook: use a food thermometer and the temperatures above.
  • Chill: refrigerate perishable food within 2 hours (1 hour above 90°F). Fridge 40°F or below, freezer 0°F or below. Thaw in the fridge, not on the counter.

For meal prep and lunchboxes

  • Cool big batches quickly: divide soups, rice and casseroles into shallow containers and refrigerate within 2 hours.
  • Most cooked leftovers keep 3 to 4 days in the fridge. Plan to eat or freeze prep-day food within that window.
  • Reheat leftovers to 165°F.
  • Pack cold lunches with an ice pack in an insulated bag. For hot lunches, fill an insulated food jar with boiling water for a few minutes, empty it, then add food heated to 165°F.
