Hello all.

Does anyone know if a food handlers permit/certificate is needed for someone who volunteers to make food for a public event?
I know people prepare foods for potlucks at church or public events... and pretty sure they don't have permits... so, I guess I don't understand how they work.
Does someone who VOLUNTEERS to make food for the public need one? Is it just for people that SELL food?

I keep searching on the internet, but can't find anything specific! I found lots of stuff... but nothing SPECIFIC.

This is for the state of MD.
