Which of the following is a common virus that can contaminate food?

Norovirus is a highly contagious virus and is one of the most common causes of foodborne illness outbreaks. It is often associated with consuming contaminated food or water, as well as through contact with infected individuals or surfaces. This virus can survive on surfaces for extended periods and is resistant to many common disinfectants, making it a significant concern in food safety.

Unlike the other options listed, which are primarily bacterial pathogens, Norovirus is classified as a virus. Common sources of Norovirus contamination include raw or undercooked shellfish, leafy greens, and any food that has been handled by an infected person without proper hand hygiene. This information highlights the importance of practicing good personal hygiene, such as frequent handwashing, especially in food preparation areas, to prevent the spread of this virus.
