Final answer:
Sliced watermelon is classified as a time/temperature control for safety food (TCS/PHF) because it requires temperature control to prevent bacterial growth. Other options like whole apples, uncooked rice, and graham crackers are not TCS foods as they do not support rapid bacteria growth at the same rate when left at room temperature.
Correct option is d. Sliced watermelon
Step-by-step explanation:
The food classified as a time/temperature control for safety food (TCS/PHF) is sliced watermelon. TCS foods are those that need time and temperature control to prevent the growth of microorganisms and the production of toxins. Examples of TCS foods include dairy products, meat, sliced fruits, and vegetables. They become unsafe when they are in the temperature danger zone of 4 to 60 degrees C (40 to 140 degrees F) for more than two hours. Whole apples, uncooked rice, and graham crackers are generally not considered TCS foods because they do not support the rapid bacteria growth that TCS foods do when held at improper temperatures.
It's important to note the food safety practices such as regular handwashing, using a thermometer to ensure foods reach safe internal temperatures, and proper storage of perishable foods. As part of food hygiene, it is also crucial to wash the outer rind of melons before cutting to prevent cross-contamination of the flesh from pathogens that may be present on the surface.
