So you can fix this by using a 1:4 slurry of abs and acetone. You’ll want to do a minimum of 3 dips and allow it to cure in a heated print chamber for at lest 16 hours but preferably 24. Also important, Reinforce the layers by either printing parallel to the angle of use or by attaching the print to a sturdier material, you wouldn’t want it to break across layer lines in use.

With ABS you might be able to fix it with an acetone bath to re-melt the top layer, but I haven’t checked.

There is food-safe filament for 3D printers but it isn’t ABS. I just wouldn’t do it at all, indeed like you said for the layer lines creating perfect spots for bacteria. But also because most of the filaments or plastic used for filaments are made in China and they tend to use harmful chemicals to cheap out on production or their machines are covered in bad chemicals for lubrication for example, ending up in/on your filament.
