Question

The time-temperature indicators on the outside of refrigerated cases of product tell if the product was -

A) Properly stored
B) Recently delivered
C) Exposed to light
D) Contaminated

Answer 1

Time-temperature indicators on refrigerated cases help determine if a product has been properly stored, by showing if it has been exposed to unsafe temperatures that could lead to rapid bacterial growth and spoilage.Answer is option (a).

Step-by-step explanation:

The time-temperature indicators on refrigerated products are designed to show whether the product has been properly stored by displaying a change if the product has been exposed to temperatures outside the recommended storage range. These indicators are critically important because bacteria and other microorganisms can multiply rapidly at temperatures between 4 and 60 degrees C (40 and 140 degrees F). Therefore, perishable foods left within this danger zone for more than two hours can become unsafe to consume.

For example, if a container of milk is left at room temperature, it would spoil rapidly because the increased temperature would accelerate the chemical reactions and the growth of bacteria that cause spoilage. Similarly, storage facilities for fruits and vegetables are usually refrigerated and well ventilated because the lower temperatures slow down the spoilage processes and ventilation prevents the buildup of ethylene gas, which can hasten ripening and spoilage.
