I love reading about what you're doing and I know you are making a positive difference in the lives of the people you are serving.
At some point you may well be facing scrutiny from the law of the land (or not) so I would encourage you to take that ServSafe class because if you are ever challenged by a cranky person or authority, you can show the certificate and while you may not be producing in a certified kitchen, you are following food safety guidelines. Takes some of the air out of the argument, so to speak. I think that's all the comment was about: be prepared for the challenge so you can flip the narrative from a position of strength (knowledge).
Edited to add: what i meant by "cranky person" is someone in your neighborhood who sees what you're doing and wants to ruin it.
