Just a few of the rules I can remember for Kansas are: Plant must be USDA inspected, If you are selling by the cut/pound, the package has to come from the butcher with a kind of cut and weight of cut on the tag, you must collect sales tax if you are selling cuts, you can be audited by the USDA to make sure you are following safe handling/storage techniques. That's all I can remember, I'm sure there are tons more. It's interesting to note that in Kansas, if you sell the live animal to the person, and they pay to have it butchered there is no taxes paid, however, if you pay to have it butchered and sell the cuts, you must pay taxes on this.
