Would NSF certification or some other third party food safety standard help executives avoid prosecution, or at a minimum demonstrate good faith compliance?

Every potential prosecution would have its own set of facts, so it is impossible to state for certain whether third party certification would mitigate culpability. That said, third party certification can’t hurt companies that are serious about managing food contamination risks.

Food grade lubricants may be safely used for handling, canning, bottling, blending, chilling, cooking, cutting, slicing, and peeling on machinery components such as pumps, mixers, gearboxes, chain drives, and conveyor belts.
