    Gastroenteritis

    What Causes Gastroenteritis continued...

    Another bacteria, shigella, is often passed around in day care centers. It typically is spread from person to person, and common sources of infection are contaminated food and drinking water.

    Parasites can also cause gastroenteritis, but it's not common. You can pick up organisms such as giardia and cryptosporidium in contaminated swimming pools or by drinking contaminated water.

    There are also other unusual ways to get gastroenteritis:

    • Heavy metals (arsenic, cadmium, lead, or mercury) in drinking water
    • Eating a lot of acidic foods, like citrus fruit and tomatoes
    • Toxins that might be found in certain seafood
    • Medications such as antibiotics, antacids, laxatives, and chemotherapy drugs
