A good place to check in on legal issues is your state's dept of Agriculture. They will have info on marketing and possible legal issues that may affect you. Food safety is an increasingly important issue as it affects your customers and how you handle and market your products.
You might also check with your local county's ag extension agent. They are a wealth of information and at least can point you in the right direction. As long as you don't ship out of state the USDA probably won't affect your activities. Our state people are great.
