In reality, I wouldn't sweat it much unless you are eating it "Sushi Style".
I've been in the meat business for over 28 years.
I know for a fact that you and I both have eaten some "undesirable delicacies" in our term as carnivores.
I've seen puss bags, ulcers, worms, abcesses and a whole assortment of lovely additions to USDA inspected meat and we won't even talk about seafood!
It's nature, and until we all start to enjoy soylent green wafers, that's just the way it is.
I'd just recommend cooking that particular animal rather well done!
