A shipment of frozen shrimp arrives. Which sign indicates it was thawed and refrozen and should be rejected?

Frozen food should be received frozen solid; signs of thawing and refreezing, such as large ice crystals, pooled frozen liquid, or water stains on the case, indicate time-temperature abuse and require rejection. Being cold, solidly frozen, or properly labeled with a harvest date are all good signs, not reasons to reject. Refreezing lets pathogens grow during the thaw period.
