Shellfish (oysters, clams, mussels) pose the greatest risk to be contaminated with norovirus; there is no way to detect a contaminated oyster, clam, or mussel from a safe one.
\nBecause shellfish are filter feeders and concentrate virus particles present in their environment, shellfish become contaminated when their waters are polluted with raw sewage.<\/p>\n

2018 Contaminated Oyster Norovirus Outbreak<\/h3>\n

A\u00a02018 multi-state outbreak of Norovirus illnesses<\/a> was associated with contaminated oysters harvested in Baynes Sound, British Columbia, Canada,\u00a0 and were distributed to AK, CA, FL, HI, IL, MA, NY, and WA. The contamination was determined to be human sewage in the marine environment.
\nAccording to the the Public Health Agency of Canada<\/a>, a total of 176 cases of gastrointestinal illness linked to oyster consumption were reported in three provinces: British Columbia (137), Alberta (14), and Ontario (25). No deaths were reported. Individuals became sick between mid-March and mid-April 2018.
\nThe California Department of Public Health (CDPH)<\/a> reported approximately 100 individuals reported illness after they consumed raw British Columbia oysters sold by restaurants and retailers throughout the state.
\nAlthough the outbreak appears to be over, this outbreak is a reminder that oysters are a known risk for causing food-related illness if consumed as a raw product.<\/p>\n

Oysters can cause food-related illness if eaten raw, particularly in people with compromised immune systems. Food contaminated with noroviruses may look, smell, and taste normal.
\nNorovirus infection can be prevented through attention to proper sanitation and cooking procedures.<\/p>\n

    What is norovirus?<\/h3>\n

    Norovirus is a highly contagious virus that can cause viral gastroenteritis, often called “food poisoning” or the \u201cstomach flu.\u201d Eating raw or partially cooked shellfish can cause norovirus infection.<\/p>\n
