What is a primary technique for preventing food-borne disease in cafeteria-type food service establishments?

1. Encouraging customers to wash their hands before eating

2. Maintaining warm foods at a sufficiently high holding temperature

3. Weekly application of pesticides

4. Annual physical examinations of food service workers

The correct answer is: Maintaining warm foods at a sufficiently high holding temperature

Maintaining warm foods at a sufficiently high holding temperature is a critical technique for preventing food-borne diseases in cafeteria-type food service establishments. This practice is grounded in the principles of food safety that emphasize temperature control as a key factor in inhibiting the growth of pathogens and reducing the risk of food contamination. When foods are held at the correct high temperatures (generally above 140°F or 60°C), it creates an environment that is less conducive to the growth of bacteria and other harmful microorganisms that can lead to food-borne illnesses. Proper temperature management is essential during both the holding and serving phases of food preparation, especially in settings where food is prepared in bulk and kept warm for extended periods before being served. While practices such as encouraging hand washing, applying pesticides, and conducting regular health assessments of food service workers do contribute to overall food safety, they do not specifically address the immediate risks associated with improper food holding temperatures— a direct and significant factor in preventing food-borne diseases. This makes the maintenance of appropriate warm food holding conditions particularly vital in cafeteria settings, where a high volume of food is served to many individuals.
