Which of the following is one of the main responsibilities of a food handler?

Maintaining cleanliness and hygiene in food handling areas is a fundamental responsibility of a food handler because it directly impacts food safety and public health. Proper hygiene practices help prevent foodborne illnesses, which can arise from contamination by bacteria, viruses, or other pathogens. This responsibility encompasses a range of activities, such as washing hands frequently and thoroughly, sanitizing surfaces and equipment, ensuring proper food storage, and adhering to safe food handling practices. By prioritizing cleanliness and hygiene, food handlers play a crucial role in protecting consumers and ensuring a safe dining experience.

Other responsibilities like ensuring food is served hot can be important, but they don't encompass the broader and more critical aspect of overall food safety that hygiene practices represent. Monitoring guest satisfaction with meals, although valuable for customer service, falls outside the primary duties related to food safety and hygiene. Preparing food without any training jeopardizes the safety and quality of food, which is why training and knowledge in safe food handling practices are essential for food handlers.
