Cooking Tips:
Does Freezing Destroy Bacteria
& Parasites?
Freezing to 0 °F inactivates
any microbes -- bacteria, yeasts and molds - - present in food.
Once thawed, however, these microbes can again become active,
multiplying under the right conditions to levels that can lead
to foodborne illness. 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. However, very strict
government-supervised conditions must be met. It is not
recommended to rely on home freezing to destroy trichina.
Thorough cooking will destroy all parasites.
