What is one of the most effective ways to prevent foodborne illness?

Washing hands properly is one of the most effective ways to prevent foodborne illness because hands are a common vector for transferring harmful pathogens to food. The process of washing hands with soap and water significantly reduces the number of bacteria and viruses that can be present, particularly after handling raw foods, using the restroom, or touching potentially contaminated surfaces. Proper hand hygiene acts as a first line of defense against the spread of contaminants, which is essential in both food preparation and service environments.

While cooking food at high temperatures is also important for killing pathogens, it is not always feasible in every situation. Avoiding raw foods can help limit exposure to certain pathogens, but it does not address the myriad of ways food can become contaminated throughout handling and preparation. Similarly, while using food preservatives can extend shelf life and inhibit microbial growth, they do not eliminate the risks associated with improper food handling practices. Thus, handwashing remains a critical step in maintaining food safety at all levels.
