The correct answer is B) Shellfish in a box surrounded by crushed ice.
The other option of the question was a) items that are frozen.
The sign that food should be rejected at the loading dock when receiving is "shellfish in a box surrounded by crushed ice."
When receiving this type of food be aware if the package is broken, or it is not sealed. If something leaks, watch out. Frozen temperatures must be correct when receiving shellfish. If food smells bad or has different kind of odor as the usual, do not receive it. Shellfish in bad condition can produce diseases when people eat it.
