What is a potential consequence of not washing hands properly in food service?

Not washing hands properly in food service can lead to foodborne illness outbreaks. This is because hands can harbor harmful pathogens such as bacteria and viruses that can easily transfer to food during preparation and handling. When these pathogens are ingested, they can cause a range of illnesses, from mild gastrointestinal distress to severe, life-threatening conditions. Proper handwashing is a key practice for maintaining food safety and preventing the spread of these pathogens, thereby protecting both customers and the integrity of the food service establishment.

The other options relate to positive outcomes that are not associated with improper hand hygiene. Increased efficiency, improved customer satisfaction, and reduction in food waste are generally linked to best practices in food handling and service, which would include thorough handwashing. Failing to adhere to these practices can result in negative outcomes like foodborne illness outbreaks, which can overshadow any potential benefits associated with the other options.
