What is a sign that food should be rejected at the loading dock when receiving?

A sign that food should be rejected at the loading dock is if the packaging is damaged, torn, or shows signs of contamination, such as leaks or stains. Additionally, if the temperature of perishable items is outside safe limits, or if there is an unusual odor or discoloration, these are clear indicators that the food may be unsafe for consumption. Always check for expiration dates and proper labeling as well.
