Which of the following is considered a TCS food?

A TCS (Time/Temperature Control for Safety) food is one that requires specific temperature control in order to limit the growth of harmful microorganisms. TCS foods are typically those that are moist, nutrient-rich, and have a neutral or slightly acidic pH.

Baked potatoes are considered a TCS food because they are cooked and contain moisture, making them conducive to bacterial growth if not stored properly. They must be kept at safe temperatures to ensure that they remain safe to eat. When cooked, baked potatoes can be in the temperature danger zone if they are left out and not held at proper temperatures, which poses a risk for foodborne illnesses.

In contrast, whole-wheat bread, orange juice, and refried beans do not meet all the criteria that classify them as TCS foods in the same way that baked potatoes do. Whole-wheat bread is less prone to bacterial growth when stored properly, orange juice is acidic, which inhibits microbial growth, and canned refried beans, while they can be TCS when prepared and left in the temperature danger zone, typically do not retain moisture in the same way as baked potatoes once they are cooked and processed. Therefore, baked potatoes are the correct choice for a TCS food.
