Final answer:
To check the temperature of received packaged food, one should use a thermometer to confirm that it is either at or below 4 degrees C (40 degrees F) for cold foods, or above 60 degrees C (140 degrees F) for hot foods.
Step-by-step explanation:
To check the temperature of received packaged food, it is essential to use a thermometer to ensure that the food has maintained a safe temperature to prevent bacterial growth. For cold foods, make sure the temperature is at or below 4 degrees C (40 degrees F). For hot foods, ensure the temperature is kept above 60 degrees C (140 degrees F), and refrigerate perishable leftovers promptly.
If the refrigerator does not have a built-in thermometer, consider purchasing one to monitor the temperature, especially in situations like power outages. I
t's crucial to keep perishable foods from staying within the danger zone of 4 to 60 degrees C (40 to 140 degrees F) for more than two hours to avoid foodborne illnesses.
When using a thermometer, insert the probe into the thickest part of the food without touching the packaging, bone, or fat. This provides an accurate reading of the food's internal temperature. For refrigerated or frozen items, consider using an infrared thermometer to swiftly check the surface temperature without direct contact.
