To thaw the food, submerge the bag in cold tap water. Never use hot water, as that can cause the outer layer of the food to heat up to a temperature where harmful bacteria begins to multiply.

Using this thawing method, small packages of frozen meat or poultry (about a pound) can defrost in one hour or less. For larger items, you should estimate about 30 minutes of defrosting time per pound of food. Once the food is thawed completely, youâll need to cook it immediately.
