What is the main risk associated with improper hand-washing?

The main risk associated with improper hand-washing is cross-contamination. When food handlers fail to wash their hands thoroughly, they can inadvertently transfer harmful pathogens from their hands to food, surfaces, or utensils. This transmission can occur after handling raw foods, touching their face, or coming into contact with contaminated surfaces.

Cross-contamination is particularly dangerous because it can lead to the spread of foodborne illnesses, as bacteria and viruses thrive in many food environments. The act of washing hands correctly and frequently is a fundamental practice in food safety that minimizes these risks by removing pathogens, thereby ensuring that the food served is safe for consumption.

While other options like increased cooking times, temperature abuse, and insufficient food storage contribute to food safety issues, they are not directly related to the immediate consequences of improper hand-washing. Proper hand hygiene is crucial for preventing the introduction and spread of contaminants, making cross-contamination the primary risk in this context.
