I work in the same building as my city's sanitarian. Getting Servsafe certified is something to think about. It tends to make health inspectors think you know what you're doing. Cleanliness is paramount in the food business. The stuff he tells me about just makes me want to shake my head sometimes.
Learn the FDA Food Code as well. Read the book and know what it says. Other than that, best of luck to you!! I'd stop by, but I'm in Iowa.
