What practice promotes good hand hygiene in the food industry?

The practice that promotes good hand hygiene in the food industry is handling chemical cleaners and washing hands before handling foods. This emphasizes the importance of proper handwashing as a fundamental aspect of food safety. Effective hand hygiene helps to prevent the transfer of harmful pathogens from hands to food, thereby reducing the risk of foodborne illnesses.

Washing hands properly before food handling removes dirt, bacteria, and chemicals that might be present on the skin, ensuring that the food being prepared remains safe for consumption. It's also vital to understand that while using disposable gloves can provide a barrier, they are not a substitute for handwashing; hands must still be cleaned before putting gloves on and when switching between different tasks. Thus, the practice highlighted in the correct answer directly addresses the significance of clean hands in maintaining food safety.

Cooking food at high temperatures and storing food at appropriate temperatures are essential safety practices but do not specifically address hand hygiene. They play a role in food safety, but maintaining clean hands is the primary defense against contamination throughout food preparation.
