If your company is looking for a food-grade third-party logistics (3PL) provider, there’s a lot of vetting required to make sure it can protect the integrity of your products. From the size and cleanliness of the warehouse to the safety and procedural knowledge of employees, there are many telltale signs that distinguish the best food-grade 3PLs from the rest of the pack. One of the most important of these signs is AIB certification, which shows that a provider truly walks the walk when it comes to food product safety.
