Food Safety News Vibrio

California officials have closed some commercial shellfish farming areas while they investigate an outbreak of norovirus that has sickened at least 44 people who reported eating raw oysters from Hog Island Oysters.

The company agreed to recall its “Sweetwater” and “Atlantic” oysters from a total of more than 40 restaurants and retailers in California, according to a notice posted by the California Department of Public Health (CDPH). The company did not appear to have any information about the recall or illnesses on its website as of last night. 

A spokesperson for the CDPH told Food Safety News that the source of the highly contagious norovirus had not been determined as of yesterday afternoon. It has, however, been confirmed that norovirus is responsible for the illnesses, as opposed to other foodborne pathogens. 

UK and Ireland -Norovirus oyster outbreak

Food Safety News


Authorities in the United Kingdom and Ireland are investigating a foodborne outbreak suspected to be caused by norovirus in live oysters.

The oysters are thought to have come from Ireland and been purified in the UK and it is believed they are no longer on the market.

Harvesting records and purification operations at the unnamed implicated business in Ireland have been checked with nothing proving that oysters harvested at the time were contaminated.

A number of people fell ill in England and the investigation has pointed towards a potential norovirus outbreak linked to one restaurant.

The Food Safety Authority of Ireland (FSAI) told Food Safety News that it has sought detailed clarification on traceability and delivery channels.

Norovirus outbreaks increase during the winter months because more people are together indoors. But some venues, such as nursing homes, schools, and cruise ships, can be struck by this virus at any time. A Norovirus outbreak on a Royal Caribbean cruise ship has sickened 475 passengers.

According to the Centers for Disease Control and Prevention (CDC), 129,678 passengers were sickened on cruise ships from 2008 to 2014. That seems like a large number, but just 10% of those illnesses were norovirus. And the number of people on those cruses was 74,000,000

The purpose of this document is to set out guidance for health professionals, port health and other agency staff and the crew of affected vessels for the identification and management of Norovirus outbreaks aboard cruise vessels. It also forms the basis of an approach to minimise the impact of the disease being brought aboard a vessel by passengers and crew, particularly during periods of heightened activity of the virus in the UK and other countries where a significant number of passengers are due to join the vessel.

This is not a prescriptive document as it is recognised that each individual incident has to be managed according to the circumstances prevailing and the decisions of the outbreak control group will reflect such variations in circumstances.
