San Diego Food Handlers 2025 – 400 Free Practice Questions to Pass the Exam

Washing hands thoroughly and frequently is the most important practice for food service workers to prevent germs in food preparation because hands are one of the primary carriers of pathogens that can contaminate food. Proper handwashing removes dirt, bacteria, and viruses that can be transferred to food during preparation, which is crucial in maintaining food safety.

Hands can easily come into contact with various surfaces and food items throughout the day, increasing the risk of cross-contamination. When food handlers wash their hands using soap and warm water for at least 20 seconds, they significantly reduce the likelihood of spreading harmful microorganisms, thereby protecting customers and ensuring food safety.

While other practices such as wearing gloves, using sanitizer, and keeping food covered contribute to food safety, they are not as foundational as handwashing. Gloves can sometimes provide a false sense of security, as they can still become contaminated if not used properly. Sanitizers are effective for surfaces but do not replace the need for hand hygiene. Similarly, covering food helps prevent contamination but does not address the germs that food handlers might introduce to the food if their hands are not clean. Therefore, handwashing is emphasized as the most crucial step in preventing foodborne illness in food preparation.
