New York, NY – Many New Yorkers woke up sick on Black Friday after large Thanksgiving meals, and state health officials say food-poisoning risks tied to undercooked turkey and improperly handled leftovers may be behind a rise in stomach illness reports across New York.
According to the New York State Department of Health, the day after Thanksgiving often sees a spike in nausea, stomach cramps, diarrhea, and fatigue. While heavy meals and late-night eating can cause discomfort, experts say improperly cooked poultry and food left out too long are the leading contributors to post-holiday illness.
Large turkeys are especially difficult to cook evenly. The thickest parts—deep in the breast and thigh—often heat more slowly and may not reach the required 165°F internal temperature even when the outside looks done. Many families remove the turkey early to keep it moist, unintentionally increasing the risk of bacteria such as Salmonella and Campylobacter, both commonly found in undercooked poultry.
Leftovers present an additional risk. New York’s Thanksgiving buffets, potluck meals, and extended gatherings often leave food sitting out for hours. Once dishes remain in the “danger zone” between 40°F and 140°F for more than two hours, bacteria multiply quickly. Organisms such as Staphylococcus aureus and Bacillus cereus—both linked to food left out too long—can cause rapid-onset vomiting and stomach discomfort.
Nutrition specialists recommend discarding questionable leftovers, reheating foods to 165°F, and staying hydrated if symptoms develop. Severe vomiting, dehydration, high fever, or symptoms lasting beyond 24 hours should be evaluated by a medical professional.
ADDITIONAL SAFETY TIPS
✓ Check leftovers: Discard anything left out for more than 2 hours.
✓ Reheat properly: Heat all leftovers to 165°F before eating.
✓ Watch for symptoms: Sudden nausea, cramps, or diarrhea may indicate bacterial illness.
✓ Cook turkey fully: Verify temperature at the thickest parts of the bird.
✓ Seek care when needed: High fever, dehydration, or blood in stool warrant medical attention.
