I would add that nothing in 3D printing can be inherently food-safe given that the product cannot be sealed. One would have to use a food-grade sealant to make it truly food-safe.
Having said that, many filament makers claim “USDA food-grade,” but if you read the fine print, that only applies to the raw material meeting USDA safety standards for microbial contact. 3D printing by its nature has open pores where bacteria can accumulate and be retained.
Here’s a good writeup that sums up the do’s and don’ts, how’s and why’s.
Just in case you’re interested there was a discussion on this topic a while back that may lend additional insights.
