I'm wondering if someone can help me out here... I thought I read somewhere that you don't have to use food grade lubricants as long as it is not being used directly over a product zone or an area where the food might come into contact with. My first question is if this is stated anywhere by the FDA or if it's more of a common knowledge thing.
The next question, what about bearings that are on the outside of a conveyor and face away from the product, would you need to use food grade grease there because the food actually is on that conveyor or could you argue that since the bearing is on the outside of the conveyor that food would not touch it and therefore you could use non-food grade grease?
