Final answer:
The correct answer is option d. Reject a fish delivery if the fish appears slimy or has an off smell, as this indicates spoilage, posing a health risk to consumers.
Step-by-step explanation:
When receiving a fish delivery for your restaurant, it is essential to ensure the quality and safety of the products. The sign that should prompt you to reject the delivery is D) Slimy or off-smelling fish. Fresh fish should have a mild ocean smell (B), and a firm and elastic texture indicates good quality (C). However, a fish that is slimy or has an unpleasant odor is a clear indicator that the fish may be spoiled or not handled properly, and consuming such fish could pose health risks to your customers.
It is not uncommon for fresh fish to have a slightly higher temperature than recommended (A) if it has been out of refrigeration briefly during transport, but it should still be within safe limits. Always use a calibrated thermometer to check the internal temperature of the fish and compare it to food safety guidelines to make an informed decision.
