Question

Which is NOT a safe way to thaw frozen food?

a) Submerged in cold running water
b) At room temperature on an elevated shelf
c) In the refrigerator or walk-in cooler
d) None of the above

Answer 1

The unsafe method for thawing frozen food is at room temperature on an elevated shelf. Safe methods include thawing in the refrigerator, being submerged in cold running water, and thawing in the microwave.

Step-by-step explanation:

The question asks about unsafe methods for thawing frozen food. Not all thawing methods are safe, and identifying the ones that are not is crucial for food safety. The method that is NOT safe for thawing frozen food is b) At room temperature on an elevated shelf. This method risks the growth of bacteria as food reaches a temperature that is conducive for microorganisms to become active after being dormant while frozen.

According to the US Department of Agriculture (USDA), safe thawing methods include the following:

• Thawing in the refrigerator, which keeps the temperature at or below 4 degrees C (40 degrees F).
• Submerged in cold running water, changing the water every 30 minutes to keep it cold.
• Thawing in a microwave, followed by immediate cooking.

These methods ensure that food does not reach temperatures where bacteria can grow rapidly. Foods should be kept at safe temperatures to inhibit bacterial growth, whether being stored in the refrigerator or during the thawing process.
