There are Food Safe PLA filaments. These PLA filaments share similar qualities with ABS, in regards to temperature extremes et al. There are several on the market. (Eg. https://shop.germanreprap.com/en/pp-plastic-600g-3mm-black and http://www.formfutura.com/hdglass/ -- I've not used the HD glass personally but have been told it works well)
When shopping for food safe PLA filaments check for the Material Safety Data Sheet (MSDS) that comes with the filament. It will contain all the normal chemical warnings, some composition information, etc. but will also indicate if the material is Food and Drug Administration(FDA) approved.
PLA, food safe or not, can also have bacterialogical issues--the material is pourous enough to allow for bacterial growth. I would suggest using a polyurethane to seal the printed part to limit bacterial growth.
You will need to check what sort of extruder you have on your pinter. Many brass extruders also contain lead which can leach into the printed product. Switch to a stainless steel print head to avoid this issue.
General care--warm soapy water and handwashing.
I would not, as yet, recommend any printed product as a vessel for food--cup/bowl. This element is still somewhat new and I don't personally trust the materials for extended contact with food. (Knives/spoons et al. have much shorter contact with food vs. a plastic mug of hot coffee).
For your intended application, the piece in question would not come into direct contact with food to be consumed. As such, you should be fine with the correct filament.
