That communal hamburger thing should be an absolute deal-breaker.
Some people do not know how to handle a deer in the field.
It's why so many people think that venison tastes skunky.
+1000 on that.
If I ever found out my processor did that, it would be the last deer he did for me. Fortunatly for me my processor and I have been buddies before he got into the business, and when you take your deer in, you get YOUR deer out. He's real good about leaving them hang in big coolers to get the tenderness going.
What a lot of people don't understand is that when you take your animal in all covered in gut shot gore, and mud in the innards, the state meat inspectors don't allow the processor to do a lot of cleaning with water, as the water can carry some bugs. I don't buy all that, but thats what another processor told me a few years back.
I've always taken them home or to the farm, where they get hung, and rinsed out really good. As always the first stop is to get bags of ice to cool the meat until it can get home for a cleaning, then the ice goes back in the cavity and off to be processed.
