Can you sell food at art and craft shows?

Selling food at an arts and craft show is very risky, unless you are a professional with the proper licenses. Some show rules do not permit food at all, and the ones that do have very strict rules to make sure you comply with the laws of your area. This includes pre-packaged foods, as well as food prepared on site. There may be some lee-way with the very small fund raisers, such as a teen club bake sale, but even that is getting harder to organize, since people are more aware of the risks.
