Question

give reason: when using frozen food items one should take out only the required quantities thawed food should never be refrozen​

Answer 1

Answer:

When using frozen food items one should take out only the required quantities thawed food should never be refrozen, as while putting a thawed piece of steak or brick of cheese back into the freezer might lead to some changes in taste or texture, it's perfectly safe and poses no risks to your health.

Answer 2

Answer:

In the freezer, bacterial growth is stopped – until the food is thawed. Then the bacteria pick up right where they left off. Just because you freeze, thaw, and refreeze food won't make it unsafe. But it does increase the risk of bacterial growth to unsafe levels.
