Vibrio parahaemolyticus

Both pathogenic and non-pathogenic forms of Vibrio can be found in fish and shellfish in marine environments of the United States.  The duration of the illness is generally two to three days, with an incubation period ranging from four hours to four days after ingestion.

Only a few cases of Vibrio require hospitalization, because the disease is usually mild.  Effects take route when the organism binds to the walls of the small intestine and excretes toxin. (The secreted toxin is currently unidentified). Symptoms of Vibrio may include: diarrhea, abdominal cramps, nausea, vomiting, headache, fever, and chills.

Vibrio infections have been reported with the consumption of raw or improperly cooked fish and shellfish.  There is a correlation between Vibrio infection and the warmer months of the year. Improper refrigeration of contaminated seafood will allow proliferation, which increases risk of infection. All consumers of contaminated seafood are at risk of contracting Vibrio; however, few cases require antibiotics.

Food Safety Tip of the Day

Divide and conquer

Int'l FS icon - cooling

Large amounts of leftovers should be divided into small, shallow pans for quicker cooling. Increasing the exposed surface area of the food will help it cool more rapidly. The goal for proper food cooling is to get the inner-most temperature to less than 70°F within two hours and below 41°F within an additional four hours.
