Also, pay close attention to renewal date deadlines for any licenses or certificates you hold, as those dates can be easily overlooked and become expired, which could lead to legal issues for your business. Some licenses, permits, and regulations apply to producers on a national-scale, while others may be state- or even county-specific. Whether you are starting a new farm business or already have an existing business, there are several regulations you'll need to be aware of if you intend to produce, market, and sell your product to the public.
