The final update on a multistate outbreak of Vibrio parahaemolyticus infections linked to fresh crab meat imported from Venezuela can be found here:


  • This outbreak investigation is over.
  • As of September 18, 2018, 26 Vibrio parahaemolyticus illnesses were reported from Colorado, Delaware, District of Columbia, Louisiana, Maryland, New York City, Pennsylvania, Virginia. Nine people were hospitalized. No deaths were reported.
  • Illnesses in this outbreak started on dates ranging from April 1 to July 19, 2018.
  • FDA and regulatory officials in Maryland traced back the source of the crab meat from restaurants and grocery stores and identified multiple Venezuelan suppliers. The investigation did not identify a single firm as the only supplier of crab meat linked to the outbreak.
  • Vibrio illness typically begins 24 hours after swallowing the germ. Symptoms of infection include watery diarrhea, stomach cramping, nausea, vomiting, fever, and chills.
  • Symptoms usually lasts about 3 days, and most people recover without treatment. People with Vibrio infection should drink plenty of liquids to replace fluids lost through diarrhea.


  • To prevent Vibrio infection, don’t eat raw or undercooked shellfish, such as oysters and crab.
  • When buying fresh crab meat – especially for use in cold dishes that do not need further cooking, such as crab salad – look for the word “pasteurized” on the label.
    • Fresh crab meat may be labeled as “fresh” or “precooked” and is a ready-to-eat product. It is often sold in refrigerated plastic containers.
    • Pasteurization is the process of heating a product to a high enough temperature for a long enough time to kill illness-causing germs.
  • When preparing a hot dish containing fresh crab meat, such as crab cakes, crab dip, and crab casserole, use a food thermometer to make sure the dish is cooked to the safe minimum temperature of 165°F.
    • Reheat leftovers to the safe minimum temperature of 165°F as measured by a food thermometer.
  • Wash hands, utensils, and surfaces with hot, soapy water before and after handling or preparing dishes using fresh crab meat.
