Which of the following statements about viruses is true?

The accurate statement regarding viruses is that they can indeed be prevented by proper handwashing. This is critical in food safety, as many viral pathogens can be transmitted through contaminated hands, particularly in food service environments. Effective handwashing practices help to remove viruses that may be present on the hands after activities such as using the restroom or touching surfaces that may harbor pathogens.

While it is also true that viruses can be transmitted by people, it doesn't fully encapsulate the role of hygiene in controlling the spread of these pathogens. Proper handwashing significantly reduces the chances of transmission, making it a crucial preventive measure. The size comparison between viruses and bacteria is not applicable since viruses are generally much smaller than bacteria. Additionally, viruses do not depend on specific foods for survival; rather, they require a host to replicate and spread. Therefore, it's essential to emphasize the importance of hand hygiene in preventing viral infections in food safety practices.
