Introduction. Food poisoning occurs when you eat food contaminated with bacteria or other toxins. Symptoms include diarrhea, vomiting, and stomach cramps, and generally start 4 to 36 hours after eating contaminated food. While food poisoning is often caused by bacteria, it can also result from eating poisonous plants (some mushrooms, for instance) and animals (pufferfish). Food poisoning is especially common during summer when food may not be kept cold enough to prevent bacteria from growing.
