Imported frozen mixed berries are suspected to be behind an outbreak of norovirus in Switzerland.
The Federal Food Safety and Veterinary Office (FSVO) told Food Safety News that the agency was informed by cantonal food enforcement authorities that illnesses were probably due to berries contaminated with norovirus. A canton is a region of the country.
These regional units examined suspected contaminated berries for norovirus and found the virus, which led to the fruits being identified as the likely source of the infections.
FSVO, also known as OSAV, BLV or USAV, is the central authority for food safety in Switzerland.
