When it comes to norovirus risk, there is a broad range of foods that you should be aware of. However, shellfish are amongst the riskiest foods to consume, because it is nearly impossible to distinguish a contaminated food item from a safe one. All types of shellfish, including oysters, clams, and mussels, pose a health risk to consumers. To make matters worse, if you become infected, you are likely to spread the virus to people around you. After coming in contact with contaminated shellfish, you will usually develop watery diarrhea combined with vomiting, two hallmark signs of norovirus infection.
