St. Louis, MO (KSDK) -- Officials are investigatinga fewcases of Vibriosis in eastern Missouri, the Missouri Department of Health and Senior Services said Tuesday.

There are three cases of Vibriosisin Missouri that were identified between June 27-28, 2012.

DHSS says the infection is associated with consuming raw or undercooked shellfish, particularly oysters. Vibriosis is caused by vibrio bacteria that grow in coastal waters.

Symptoms of the disease include nausea; vomiting, diarrhea, abdominal cramps, and in some cases, signs of severe infection (septicemia), including fever and low blood pressure. DHSS says symptoms can begin within 4 to 96 hours of consuming contaminated food.

These infections can be treated with antibiotics. Cases are required to be reported within three days to a local public health agency or DHSS at 800-392-0272.

Questions can be directed to DHSS' Bureau of Communicable Disease Control and Prevention at 573-751-6268 or 800-392-0272.
