Wholeoysters

The state of Massachusetts has closed Duxbury, Plymouth, Marshfield, and Kingston Bay Complex to commercial oyster harvesting because of an outbreak of Vibrio parahaemolyticus. This is the first time those waters have been closed, despite a two-year effort of government and industry to implement safeguards against that bacteria. The Massachusetts Department of Public Health is currently investigating an outbreak of more than 40 people sickened by Vibrio this summer. Some of those illnesses have been definitively attributed to cultured oysters from that specific growing area. There is no wild harvest on those waters. All oysters harvested from this area that are in commerce are being recalled. The closure is in effect from August 30, 2013 until further notice. The symptoms of a … [Read more...]

The Seattle and King County Health Department is warning consumers of the dangers of eating raw or undercooked shellfish.

Eight Cases of Vibrio Food Poisoning Linked to Oysters Reported in Massachusetts This Year

Wholeoysters

The Cape Cod Times is reporting that eight cases of Vibrio food poisoning were reported in Massachusetts this year from oysters. Last summer the state designed new regulations to keep consumers safe from this bacteria, but they failed.  The eight cases were linked to oysters harvested from Wellfleet, Orleans, Edgartown, Duxbury, Kingston, Barnstable, and Dennis. Public health officials think that increased public awareness may be part of the cause of this outbreak, but warmer water and air temperatures this last summer may be to blame. Vibrio was not seen in Massachusetts oysters until 2011 because the state's colder water temperatures discouraged the growth of the bacteria. In every month in 2012, the mean air temperatures were higher than average, including the third-warmest April and … [Read more...]

Vibrio in Shellfish Sicken 30 in Washington State

Wholeoysters

According to the Washington State Department of Health, Vibrio in shellfish have caused 30 confirmed illnesses in Washington this summer. The presence of the bacteria has closed three commercial growing areas, including Totten Inlet near Olympic, North Bay, and Dabob Bay in north Hood Canal for the rest of the summer. Vibriosis, the illness caused by the bacteria Vibrio parahaemolyticus, is caused by eating raw or undercooked oysters. Despite the typical recommendation of cooking shellfish until they open, that is not enough to destroy Vibrio. To be safe, shellfish should be cooked to an internal temperature of 145 degrees F for 15 seconds. In addition, rinsing cooked oysters in seawater can re-contaminate them. And, some pathogens can't be "cooked out" of shellfish. Some biotoxins can … [Read more...]
