Just bear in mind that you may shoot deer in a county other than where you live, and sell to an AGHE in a county other than where you live. Would you contact all the Local Authorities involved for their opinion? No, of course not! You simply comply with the law, by registering as a food business.As I said take NO advice from this site other than contact you LA for their opinion of your individual situation!
As stalkers, we are extremely fortunate to be able to sell carcasses in this way. People who keep farmed deer can't do it, neither can people who keep sheep, cattle, pigs etc. If we abuse the system then we'll lose the privilege.
