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
| Food | Main germs | Safe practice |
|---|---|---|
| Raw or undercooked poultry, meat, ground beef | Salmonella, Campylobacter, E. coli | Cook to safe internal temperature |
| Raw or runny eggs | Salmonella | Cook until yolk and white are firm; use pasteurized eggs for raw recipes |
| Raw (unpasteurized) milk and soft cheeses made from it | Listeria, E. coli, Campylobacter | Choose pasteurized products |
| Raw oysters and shellfish | Vibrio, norovirus | Eat cooked |
| Raw sprouts, unwashed leafy greens | E. coli, Salmonella | Rinse greens; cook sprouts if at higher risk |
| Deli meats, hot dogs, smoked fish | Listeria | Higher-risk groups: heat until steaming hot |
| Cooked rice and pasta left out | Bacillus cereus | Refrigerate 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
- 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.
- Separate: separate cutting boards and plates for raw meat and ready-to-eat foods.
- 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.
- 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.
