I work for a city in the Dallas area. We have a "swap meet" that is city-wide which is similar to Craigslist. I put a post on there a couple days ago for "Farm fresh eggs from free range chickens - $3." I have posted eggs for sale several times in the last couple years. WELL..... I just got a call from someone in the City Health Department. At first I thought she wanted to buy them. Not so much. She proceeded to tell me that it violates the City health code to sell food without a permit. I was also told it is against City policy to sell food on the swap meet. Needless to say, I had to remove the post.
I guess if I lived somewhere more rural it wouldn't be an issue...
