Illustration: Avoid Food Poisoning: High-Risk and Low-Risk Foods

About 48 million Americans get sick from foodborne illness each year. Most cases are mild, but some groups — pregnant women, young children, older adults and people with weakened immunity — are at risk of serious illness. Knowing which foods are risky and following four simple rules prevents most of it.

Higher-risk foods

FoodMain germsSafe practice
Raw or undercooked poultry, meat, ground beefSalmonella, Campylobacter, E. coliCook to safe internal temperature
Raw or runny eggsSalmonellaCook until yolk and white are firm; use pasteurized eggs for raw recipes
Raw (unpasteurized) milk and soft cheeses made from itListeria, E. coli, CampylobacterChoose pasteurized products
Raw oysters and shellfishVibrio, norovirusEat cooked
Raw sprouts, unwashed leafy greensE. coli, SalmonellaRinse greens; cook sprouts if at higher risk
Deli meats, hot dogs, smoked fishListeriaHigher-risk groups: heat until steaming hot
Cooked rice and pasta left outBacillus cereusRefrigerate within 2 hours

Lower-risk foods

Well-cooked foods eaten right away, hard cheeses, pasteurized dairy, washed whole fruits and vegetables, bread, dried foods and canned foods from undamaged cans.

The four rules: clean, separate, cook, chill

  1. Clean: wash hands for 20 seconds before cooking and after handling raw meat; wash surfaces and produce. Don't wash raw chicken — it spreads bacteria.
  2. Separate: separate cutting boards and plates for raw meat and ready-to-eat foods.
  3. Cook: use a food thermometer — poultry 165 °F (74 °C), ground meat 160 °F (71 °C), whole cuts of beef, pork and lamb 145 °F (63 °C) with a 3-minute rest, fish 145 °F.
  4. Chill: keep the fridge at 40 °F (4 °C) or below; refrigerate leftovers within 2 hours (1 hour if it's above 90 °F outside); thaw in the fridge, not on the counter.

When to see a doctor

Bloody diarrhea, fever above 102 °F (38.9 °C), diarrhea lasting more than 3 days, frequent vomiting that prevents keeping fluids down, or signs of dehydration (little urine, dizziness). Pregnant women with fever after eating a risky food should call their doctor — Listeria can harm the baby.
