Why is rapid cooling of hot foods important for food safety?
The cooling step gives bacteria a chance to multiply to dangerous levels—if bacteria growth isn’t controlled while food cools. That’s why the FDA guidelines are so effective. These guidelines ensure that food passes through the temperature danger zone quickly so bacteria don’t have a chance to make food unsafe.
What is the minimum temperature for reheating food?
Food made in-house and reheated for hot holding must reach an internal temperature of at least 165°F for 15 seconds. Food made in a food processing plant, opened in the food establishment, and reheated for hot holding must reach a temperature of 135°F. Reheat food rapidly, within two hours.

Which is colder in the fridge 1 or 5?
Some fridges don’t show the temperature but work on a setting that is listed from 1 to 5. The numbers on the fridge’s temperature dial indicate the refrigerating power. Therefore, the higher the setting, the cooler the fridge will be. Choosing setting 5 will make your fridge the coldest.
What is best setting for fridge?
between 37°F and 40°F
Check the temperature setting on your refrigerator. It should be set between 37°F and 40°F—the ideal refrigerator temperature to keep food fresh and cold but not frozen. If you have a numbered dial setting instead of a temperature reading, the highest number is the coldest (usually 5).
What number should I set my fridge to?

Keep your appliances at the proper temperatures.
The freezer temperature should be 0° F (-18° C).
Is 2 degrees too cold for a fridge?
The temperature inside your refrigerator needs to be cold enough to inhibit bacterial growth, and warm enough so the food doesn’t freeze. Refrigerators should be set to 40 degrees F (4 degrees C) or colder. A good temperature range for a refrigerator is between 34-38 degrees F (1-3 degrees C).
Do refrigerators run better full or empty?
Answer: A Refrigerator Works Better 3/4 Full
Keeping a refrigerator at 3/4 full is where it’s at. This allows the refrigerator to operate at maximum efficiency. Air circulation is unhindered and freely moving, and the food is properly absorbing the cold to assist in the process.
