Question

a shipment of frozen fish arrives at your food establishment. you see that the outside bottoms of the shipping cartons have too much ice and the fish fillets held within the cartons have ice crystals. these are signs of: thawing and refreezing, being safe, high quality, being kept in frozen storage too long, blast chilling

Explanation:

Thawing and refreezing of frozen food (like fish) can lead to ice formation on the outside of shipping cartons and ice crystals within the product. When food thaws, moisture melts and then refreezes, creating these ice - related signs. High - quality, safe frozen food shouldn't have excess ice, long - term frozen storage alone doesn't typically cause such external ice on cartons, and blast chilling is a quick - freezing method that doesn't result in this ice formation pattern.

Answer:

Thawing and refreezing
