    Understanding Food Poisoning -- Symptoms

    What Are the Symptoms of Food Poisoning?

    Generally, food poisoning causes some combination of nausea, vomiting, and diarrhea that may or may not be bloody, sometimes with other symptoms.

    • After eating tainted food, abdominal cramps, diarrhea, and vomiting, can start as early as one hour in the case of staph and as late as 10 days in the case of campylobacter. It may take even longer to develop symptoms from parasite infections such as Giardia. Symptoms can last from one day up to a couple of months or longer, depending on the type of infection.
    • Vomiting, diarrhea, sweating, dizziness, tearing in the eyes, excessive salivation, mental confusion, and stomach pain may be symptoms of chemical or toxin food poisoning such as that from poisonous mushrooms.
    • Partial loss of speech or blurred vision, muscle weakness, difficulty swallowing, dry mouth, muscle paralysis from the head down through the body, and vomiting may indicate botulism, a severe but very rare type of bacterial food poisoning.
