Deer stalking
No, you can?t. The law on selling venison includes swapping or bartering, so you can only do that if you are qualified to handle meat for public consumption and if it is properly marked and recorded by both you and the recipient.

You may feed your family and guests on venison you have shot but can only dispose of it by way of trade if you are qualified to do so and if both you and the recipient comply with the law on correct handling and recording.
