If you are selling to the public, the animal must be slaughered and butchered in an approved premises - for our small numbers, it's not worth setting up as a butcher's cutting room, so yes, animals go off to the abattoir; from there to the butcher, who cuts, vac packs and labels, then we pick the meat up from there and sort it into 10kg boxes as a mix of joints, steaks, stewing and braising cuts, mince, burgers and sausages. We tot up the weights as we go and it's generally about 11kg. We charge £125 per box. This year we sold 20 and we've still got a lot of sausages (BBQ summer please this year), mince and some other bits and pieces in the freezer that we're selling off.
The whole / half lambs, we weigh and charge at £11.50/kg.
We have our own labels but we just use the butcher's prices for individual cuts.
Don't forget to register with your local EHO. The burden for selling fresh and frozen meat in small quantities isn't high, the way we do it. We need to have thermometers in the freezers and record the temperatures daily.
