Which of the following is considered a TCS food?

A TCS (Time/Temperature Control for Safety) food is any food that requires specific time and temperature controls to remain safe for consumption. This designation typically includes foods that are more prone to bacterial growth and spoilage, especially those that are high in moisture or protein.

Sliced tomatoes are classified as TCS foods because once they are cut, they provide an opportunity for bacteria to grow due to increased surface area exposure and moisture. This vulnerability necessitates careful temperature management to prevent foodborne illnesses. Proper handling, such as keeping them refrigerated and using them promptly, is essential to ensure food safety.

In contrast, air-cooled hard boiled eggs, dry cereal, and commercially prepared mayonnaise do not fall under the TCS category because they are generally stable at room temperature for longer periods and do not support rapid bacterial growth to the same extent as cut produce. This distinction emphasizes the importance of understanding which foods require more stringent control measures to maintain safety.
