Question

A shipment of frozen fish arrives at your food establishment. Signs of brown edges on fillets and excessive ice on cartons indicate:

A. Blast chilling
B. Being safe, high quality
C. Thawing and refreezing
D. Being kept in frozen storage too long

Answer 1

Brown edges on fillets and excessive ice on cartons indicate thawing and refreezing of the fish, which can compromise its quality and safety.

Step-by-step explanation:

Signs of brown edges on fillets and excessive ice on cartons in a shipment of frozen fish indicate C. Thawing and refreezing. Such conditions suggest that the fish was not maintained at a consistent, sufficiently low temperature, leading to a partial thaw before being refrozen.

This can compromise the quality and safety of the fish. To avoid these issues, it is important to educate food handlers about maintaining appropriate freezer temperatures and proper food handling protocols, including minimizing freezer burn by wrapping food tightly before freezing and thawing food in safe ways recommended by the US Department of Agriculture (USDA).
