Don't we do this already?What also holds things back is the lack of an immutable level of traceability from field to fork, showing that the carcass has been kept appropriately from the shot onwards. Nick Rout touched on this last night, with talk of carcass tags - he mentioned ear tags similar to those used for livestock, but I can also see a place for the type of carcass tags used in the US. I can imagine the uproar from the stalking community were such an idea to be touted, but quite frankly whilst the largely voluntary system that is in place at present may do what it is designed for, it is still pretty rudimentary when it comes to supply chain best practice.
You shoot a deer and tag it with your hunter number, deliver to game dealer, job done.
Or are you referring to shooting and producing it yourself?
All you need to do is mark on your label your own reference number.
It cannot be compared to the US system, you pay for a TAG to hunt, once harvested the TAG remains with the carcass, they can't split it down and sell the meat, that would be illegal.
But what the US does have is food banks, they are very well setup, it's where I have delivered my game in the past, one even charged me a $20 processing fee!
