I quarter my deer and put it in a cooler on ice with drain plug open for 3 days. While packaging, I got 3/4 of it done and got to the last hind quarter, deboned it and beginning to cut into thirds when there was a lime green oooz between the muscle where there is cartilage. There was no sign of a wound while skinning nor a bad smell skinning or packaging. Like to send you a couple photos to help others.
