Which of the following food shipments is most likely to be rejected?

The chosen answer highlights an important aspect of food safety, particularly concerning the freshness and quality of seafood. When fish have dull, sunken eyes, it indicates that they are not fresh and may be spoiled. Fresh fish typically have clear, bulging eyes, which is a sign of good quality and proper handling. Eyes that are sunken and dull suggest that the fish has been stored improperly or for too long, leading to potential foodborne illnesses if consumed.

In contrast, eggs received at 45°F can still be acceptable if they are kept at or below that temperature, as they are typically considered safe when managed properly. Clams with their shells closed indicate that they are alive and fresh, which is desirable. Firm chicken that springs back when touched reflects proper handling and freshness, suggesting it has been stored correctly. Each of these alternatives demonstrates that the products meet safety standards, while the fish with dull, sunken eyes fails to meet the criterion for freshness and therefore would likely be rejected based on these quality indicators.
