At what temperature should frozen food be stored?

0° FKeep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these temperatures and are generally inexpensive.

What is the 2 4 hour rule?

Can water be colder than 0 degrees?

Yes, water can stay liquid below zero degrees Celsius. … When we apply pressure to a liquid, we force the molecules to get closer together. They can therefore form stable bonds and become a solid even if they have a higher temperature than the freezing point at standard pressure.

Will water freeze at 20 degrees?

There is no simple answer. Water freezes at 32 degrees Fahrenheit, but indoor pipes are somewhat protected from outdoor temperature extremes, even in unheated areas of the house like in the attic or garage. … As a general rule, temperatures outside must drop to at least 20 degrees or lower to cause pipes to freeze.

Why are foods frozen at a temperature below zero?

Freezing to 0 °F inactivates any microbes — bacteria, yeasts and molds — present in food. … Since they will then grow at about the same rate as microorganisms on fresh food, you must handle thawed items as you would any perishable food. Trichina and other parasites can be destroyed by sub-zero freezing temperatures.

These foods are still safe to eat, but may not taste good.

What is the 4 hour rule?

What is the 4-hour/2-hour rule? Studies show that food can be safely held out of temperature control for short periods of time without significantly increasing the risk of food poisoning. … However, the total time in the temperature danger zone must not be longer than 4 hours.
