What type of food cannot be offered for self-service except in specific circumstances?

Raw, unpackaged food cannot be offered for self-service except in specific circumstances primarily due to food safety concerns. Raw food items pose a higher risk for foodborne illnesses if they are not handled and monitored correctly. When food is presented for self-service, there is a greater chance of cross-contamination and improper temperature maintenance, which can lead to serious health risks.

In many jurisdictions, the regulations specify that raw foods such as meat, poultry, seafood, and certain vegetables must be prepared by a food handler to ensure proper cooking temperatures and to minimize contamination risks. These foods may be offered for self-service only in designated situations with strict guidelines in place, such as when they are part of a supervised buffet with appropriate food safety measures, or when they are pre-packaged and already prepared in a safe manner.

Other food items like packaged snacks, cooked meats, and fruits and vegetables usually present lower risks and can be more safely handled in a self-service environment, adhering to general food safety protocols.
