Final answer:
Time and temperature checks should be performed at minimum every 4 hours according to the FDA Food Code, but more frequent checks every 2 hours are recommended for better food safety.
Step-by-step explanation:
The question about time and temperature checks is related to food safety protocols, which are essential for preventing foodborne illnesses. These protocols typically recommend checking the temperature of food at regular intervals to ensure that it is being stored safely. This is particularly important for food being held at temperature, such as on a buffet or in a warming unit.
The Food and Drug Administration (FDA) Food Code recommends that food temperatures be checked at least every four hours. However, if the food is being held at a temperature above 135 degrees Fahrenheit (which is the recommended holding temperature for hot foods), checking every two hours allows for quicker corrective actions if the temperature falls out of the safe zone.
Therefore, the correct answer to the student's question is: Time and temperature checks should be performed at minimum every 4 hours, but more frequent checks at every 2 hours are advisable for better safety.
