Which coating? Benchmade has 4 - Cerakote, BK1, BT2, BP1.
Most Grips that are coated with BK1 which has been described as similar to teflon.
While many 'liquid' protection coatings like Tuff Glide are not food safe and come off the blade relatively easily. But hard coatings don't come off so easily and when it does not in significant quantities.
Most likely any artificial coating on a blade is probably not a good thing to eat. Just depends on how much is consumed. Even teflon eventually wears off and gets in your food.
BTW, is the epoxy coating on Becker or ESEE knives 'food safe'? But they doesn't come off easily, certainly not due to the rigors of food prep.
And what do you oil your uncoated blades with? Is it food safe?
Frankly, I'd be more concerned about the contaminated food/water supply the animal/vegetable I prep'ing had been exposed to than the hard coating on the blade.
