Which delivery condition is a valid reason to REJECT a shipment of fresh produce and packaged foods?

解析

Deliveries must be rejected when packaging is torn, punctured, or water-stained, when there is evidence of pests such as droppings or gnaw marks, or when there are off odors, slime, or mold, because these indicate contamination or abuse. Cold crisp lettuce, a sealed lot-coded bag of flour, and squarely stacked cases with nothing crushed or leaking are all signs of an acceptable load, not grounds for rejection. The receiving inspection is a key control before food enters storage.
