When deer lay overnite, the gas in the stomach will cause some bloating.
So,when you go to gut it, it is quite easy to accidently cut open the gut because of it being swelled up. When most guys get a whiff of this, they assume that the deer is spoiled and won't take it. Some won't even gut it because it is bloated and they say it is spoiled.
I've had to finish a tracking job in the morning on a few occasions. The weather was quite warm. And yes the deer had a smell to it when I gutted it. Friends that were with me those times, said it was spoiled and I was nuts for taking it. I'd take them anyway and they tasted fine.
That speaks volumes and I highly doubt unless extreme temperatures are taken into considerations that the meat will be spoiled, tenderized yes, spoiled, no.
I've read where top chefs will claim that venison is not even ready to be cooked until it ages, aging venison they will let it hang until the green mold starts on the outside, wipe it down with vineger and cook it, now even for me that is extreme. Unless your deer lays in the extreme heat and in the sun where insects play a role, overnight cooler temperatures won't spoil your meat.
