Will you get sick if you eat cooked green beans that have turned sour in the refrigerator?

Yes, eating cooked green beans that have turned sour in the refrigerator can pose a risk of foodborne illness. Sourness may indicate spoilage, which can be caused by bacterial growth. It's best to avoid consuming any food that shows signs of spoilage, including off smells or changes in texture, to prevent potential sickness. When in doubt, it's safer to discard the food.
