Boston, MA – Many Massachusetts residents woke up sick on Black Friday after large Thanksgiving meals, and state health officials say food safety issues involving undercooked turkey and improperly handled leftovers may be driving a spike in stomach illness reports.
According to the Massachusetts Department of Public Health, the day after Thanksgiving often brings a rise in nausea, stomach cramps, diarrhea, and fatigue. While overeating rich holiday foods can contribute, experts say undercooked poultry and dishes left out too long are among the most common causes of post-holiday illness in the state.
Large turkeys are especially difficult to cook evenly. The thickest sections of the bird—particularly deep in the breast and thigh—may not reach the required 165°F internal temperature even when the exterior appears fully done. Many families remove the turkey early to preserve moisture, unintentionally increasing exposure to bacteria such as Salmonella and Campylobacter, both widely associated with poultry.
Improper leftover handling adds to the risk. Thanksgiving potlucks, buffet-style meals, and long family gatherings often lead to food sitting out for hours. Once dishes remain in the “danger zone” between 40°F and 140°F for more than two hours, bacteria can multiply rapidly. Organisms such as Staphylococcus aureus and Bacillus cereus—two of the most common pathogens tied to food left out too long—can cause fast-onset vomiting and stomach discomfort.
Nutrition specialists recommend discarding questionable leftovers, reheating food thoroughly to 165°F, and staying hydrated if symptoms arise. Severe vomiting, dehydration, high fever, or symptoms lasting more than 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.
