Step-by-step explanation:
Frozen food should always be received following proper food safety guidelines. It is important to ensure that the temperature in the freezer is kept consistently below -2°C (28°F) to inhibit bacterial growth and preserve the quality of the food. Thawing frozen foods should be done in a safe manner, either in the refrigerator, in cold water changed every 30 minutes, or in the microwave, to prevent bacterial growth in the thawed food. It is essential to avoid refreezing food once it has thawed to maintain its safety and quality.
