Can expired onions (whole) make you sick?
Yes — but the printed date isn't the trigger. Foodborne illness comes from bacterial growth (Salmonella, E. coli, Listeria, Staphylococcus) or fungal toxins, which depend on storage temperature and time, not the calendar date on the package.
Symptoms of food poisoning typically appear within 6–48 hours and include nausea, vomiting, diarrhea, stomach cramps, and fever. Severe cases — especially in young children, elderly, pregnant, or immunocompromised people — warrant medical attention. The safest practice: when in doubt, throw it out.
