We recently had a truck load of products refused at their destination due to ants on products. When the truck was loaded at our dock there were no ants present and the driver checked the BOL showing there were no rodents, bugs or bad odors and signed for the load. However, when it arrived 200 miles away there WERE ants on bags of product as shown in pictures that were provided by the refusal party. So, my question to the forum is how to handle an issue like this where all parties do not admit liability and how to keep it from happening again in the corrective action sense? Is there a template for transportation companies to fill out concerning what is done on their end to assure their trucks are maintained in a way that prevents contamination? Currently, we access the inside and outside condition of the vehicle but, what measures should be taken by the transporting party to ensure safe movement of products once it leaves our dock? Any help would be greatly appreciated.
