Norovirus and Food Safety

Norovirus is a common foodborne illness that is easily spread, especially in certain settings, such as cruise ships and restaurants. Understanding how this virus affects food safety can help food workers prevent outbreaks.

What Is Norovirus?

Norovirus is a contagious illness that causes vomiting, diarrhea and stomach pain that goes from one to three days on average. In severe cases, this virus can lead to dehydration that requires hospitalization, especially in the elderly, in children and in those with other health issues. You can get norovirus from consuming contaminated water or food, from touching your mouth after coming into contact with a contaminated surface, or from being around those who have this virus. Norovirus typically clears up on its own after running its course, but drinking plenty of fluids is important to prevent dehydration.
