What is the most important measure to prevent foodborne illness caused by viruses?

Practicing personal hygiene is crucial in preventing foodborne illness caused by viruses because many viruses, such as norovirus and hepatitis A, can be easily transmitted through contaminated hands. Personal hygiene practices, including regular handwashing with soap and water, are essential for anyone involved in food preparation and handling. Proper handwashing helps remove harmful pathogens that may be present on the hands, which can easily contaminate food and surfaces if not properly managed.

In the context of food safety, other options like cooking food to proper temperatures and avoiding high-risk foods play significant roles in controlling bacterial growth and foodborne illness caused by bacteria. However, when it comes to viruses, improving personal hygiene is the most effective measure since viruses are often transmitted through close contact and contaminated surfaces rather than through undercooked food. Using gloves can also contribute to food safety, but they are not a substitute for proper handwashing and personal hygiene practices, as gloves can become contaminated just like hands. Hence, maintaining high personal hygiene standards is the most effective strategy for preventing virus-related foodborne illnesses.
