Storing spoiled meat with fresh meat in a freezer
I just bought a new chest freezer to store some lamb and beef. I placed the fresh lamb meat in a couple of metal containers (not covered) and put these in the freezer. I did the same with the beef but in different containers (not covered) and put them into the same freezer. However, after already dropping a couple of the beef containers in the freezer, I noticed a pungent smell of spoiled beef coming out of the one last container.
I immediately opened the freezer and removed the other beef containers out of it. They must have been in there for like 5-10 minutes tops. The thing is that the freezer is ridden with the rancid smell of spoiled meat and it just doesn't seem to go away. The lamb is fresh and unspoiled. But that's what I'm worried about: if that spoiled batch of beef had an effect on the lamb and spoiled it as well.
Can that happen? Can you spoil fresh meat in a freezer by putting spoiled meat next to it in the same freezer (in uncovered separate vessels/containers, of course)? Or is it just the smell of that spoiled batch of meat and nothing to worry about?
Best Answer
The chemicals associated with the odor of rancid or spoiled meat can indeed float around in a freezer and condense on other surfaces, such as the other meats.* Since these chemicals are detectable at extremely low concentrations, even a small amount of migration would make those objects noticeably rotten-smelling.
That probably didn't happen to the meat, though. Vapor doesn't want to condense just anywhere; it wants to condense on cold surfaces. And the coldest thing in your freezer, at least for a few hours after you initially filled it, is the freezer itself. I think it most likely that the surfaces of the freezer -- and the air in it, for that matter -- are the only things with a significant residual odor.
If you like, scrub down the sides of the freezer with a dilute ammonia solution (aka window cleaner). But I don't think you need to do anything about the rest of the meat.
* On one occasion, a roadkilled skunk was stored for some time in a refrigerator. The mercaptans from the scent glands turned the butter (it was not a roadkilled-skunk-specific refrigerator) into, well, skunk butter. "You can't pick your family", as they say.

Can you freeze spoiled meat?
If you don't plan on eating your meat within the FDA-recommended time periods, you can keep your meat from going bad by freezing it at 0 degrees F. The USDA says that freezing food at this temperature inactivates bacteria and other microbes. Freezing food can even help destroy certain parasites.Does freezing fresh meat affect quality?
If your beef is loosely wrapped and frozen slowly (or frozen marginally), you risk losing the quality of the meat and subject it to freezer burn. When meat is frozen slowly, the water in it turns to ice crystals that grow large and rupture the fibre or muscle cell structure.BUTCHER EXPLAINS AGING MEAT VS ROTTEN MEAT - How Do You Age Meat Safely?
