Final answer:
A baked potato is a TCS food because it requires careful temperature management to prevent the growth of bacteria and other pathogens.
Step-by-step explanation:
The question 'Which is a TCS food? Select one: a. Saltines b. Bananas c. Baked potato d. Coffee' relates to food safety and the identification of foods that require time and temperature control for safety (TCS foods). Among the options provided, the correct answer is c. Baked potato. TCS foods are often moist, rich in protein, and neutral or slightly acidic. These foods require careful temperature management to prevent the growth of bacteria and other pathogens. Examples of TCS foods include meat, dairy products, cooked vegetables like baked potatoes, and cooked rice or beans. In contrast, saltines, bananas, and coffee, do not generally fall into the category of TCS foods, as they do not support the growth of harmful microorganisms as easily.
