What does proper handwashing help prevent in food establishments?

Proper handwashing plays a crucial role in preventing foodborne illnesses in food establishments. Handwashing is an effective way to remove harmful pathogens, such as bacteria and viruses, that can be transferred to food through contaminated hands. When food employees wash their hands properly, they significantly reduce the risk of these pathogens being introduced to food items, which could lead to foodborne illnesses among customers.

Maintaining hygiene through effective handwashing is particularly vital in food service environments where the handling of raw and cooked foods occurs. By eliminating germs and contaminants from hands, food handlers help ensure that the food served is safe to consume, thereby protecting public health and enhancing overall food safety standards.

The other options relate to different aspects of food management but do not specifically address the critical role of handwashing in preventing illness. Spoiled food pertains to improper food storage and handling practices, waste accumulation involves managing waste efficiently, and bad odors derive from various sources unrelated to hand hygiene. Thus, the effectiveness of handwashing directly connects to reducing foodborne illnesses, making it the most appropriate answer.
