The Connecticut Department of Agriculture has initiated a shellfish closure and voluntary recall of some oysters and clams harvested from the waters of Norwalk and Westport. The affected areas are now closed to harvest until further notice.
Raw or undercooked shellfish have been implicated as the source of a number of illnesses related to the naturally occurring bacterium Vibrio parahaemolyticus, state agricultural officials said.
Oysters, mussels, hard clams, littleneck clams, chowder clams, quahogs, and soft-shell/steamer clams from the affected areas are harvested both commercially and recreationally. A commercial recall is underway.
“If any doubt, throw it out’
“We are advising the public not to consume shellfish obtained from the closed recreational and commercial areas, and to discard recalled shellfish to reduce the risk of contaminating other food and food contact surfaces,” state Agriculture Commissioner Steven K. Reviczky said.
“I want to emphasize the importance of heeding this advice. If there is any doubt, throw it out, regardless of how much you love shellfish,” Reviczky said. “It’s just not worth risking the health of you or your loved ones.”
Inquire about harvest location
Consumers who have purchased hard clams or oysters and are concerned that they may be affected by this recall should speak with the retail establishment regarding the harvest location of the shellfish that were purchased (see a list of the impacted harvest locations later in this article).
Restaurants and retail establishments that believe they have this product on hand should contact their local health department for further instruction.
Symptoms of the infection
Symptoms of V. parahaemolyticus infection include diarrhea, stomach cramps, nausea, vomiting, headache, fever and chills.
Symptoms usually appear 12 to 24 hours after eating contaminated shellfish, and can last two to seven days.
Vibrio infections can be life-threatening for immune-compromised people or those with chronic liver disease.
Also at greater risk are people who regularly take antacids, heart or diabetes medication, and those who have had antibiotic or cancer treatments recently.
Consumers with questions about their individual risks related to shellfish consumption should contact their doctors.
Consumers who think they might have become ill from eating contaminated shellfish should notify their local health departments, as well as consult their healthcare providers for appropriate follow-up and treatment and to request a test be performed to detect Vibrio bacteria.
