What is one important reason for washing hands before handling food?

Washing hands before handling food is crucial primarily to prevent cross-contamination. When food handlers do not wash their hands, they risk transferring bacteria, viruses, and other harmful microorganisms from their hands to the food. These pathogens can come from many sources, including raw meat, poultry, or contaminated surfaces, and can lead to foodborne illnesses if ingested. Proper hand hygiene is an essential practice in food safety, ensuring that food remains safe for consumers and reducing the risk of contamination during preparation and serving.

Other options, while related to food handling, do not accurately capture the primary purpose of handwashing in this context. Enhancing flavor or testing for freshness doesn't relate to health safety, and avoiding food waste focuses on different aspects of food preparation that don't involve hygiene practices. Thus, maintaining clean hands is a critical step in ensuring food safety and preventing illness.
