This is one of those times it's probably good to remind people that the way the tallow comes in is often in chemical tankers. They'll make it to the agricultural docks sooner or later among their rotation between chemical plants when they get here.
You're depending on the integrity of the ship's personnel as to how well they cleaned the vessel compartments overseas before loading the tallow, when the odds are extremely high that the previous cargo in one or more of the tanks was quite toxic.
Yum.
