Final answer:
Thawing food at room temperature for a maximum of 2 hours is NOT an acceptable way to thaw food.
Step-by-step explanation:
The correct answer is B. At room temperature for a maximum of 2 hours.
Thawing food at room temperature is not safe because it allows bacteria to multiply rapidly. Bacteria generally multiply most rapidly at temperatures between about 4 and 60 degrees C (40 and 140 degrees F). Perishable foods that remain within that temperature range for more than two hours may become dangerous to eat because of rapid bacterial growth.
The acceptable ways to thaw food are: A. In a refrigerator at a product temperature of 45*F or lower; C. Under running potable water at a temperature of 70*F or lower; and D. In a microwave as long as the food will be cooked within 24 hours.
