Which practice is effective in preventing Norovirus from causing foodborne illness?

Correct handwashing is effective in preventing Norovirus from causing foodborne illness because the virus is highly contagious and can spread easily through contaminated food, surfaces, and direct person-to-person contact. Proper handwashing involves using soap and water to thoroughly clean the hands, especially after using the restroom, before handling food, and after touching surfaces that may be contaminated.

Norovirus is resilient and can survive on surfaces, so washing hands effectively helps eliminate the virus from the skin, significantly reducing the risk of transmission. While using disposable utensils, wrapping food tightly, and using gloves are practices that may help in specific circumstances, they do not address the crucial factor of hand hygiene, which is the primary defense against the spread of Norovirus in food preparation and handling environments.
