Over the years, I've opened plenty of cryo packs that gave off a different smell than normal. Followed the advice I gave above and have never had a problem with it. Of course, if it's green or still foul smelling after a rinse, it gets trashed and my butcher gets an earful. :)
I don't mess with funny smelling meat. I buy 95% of my meat at the same grocer and I'm in there 3-5 times a week picking up things I need. They know me. I've taken a chicken and a pork tenderloin back because they didn't smell, feel, or look right. They took them back no questions asked. Didn't have the receipt with the pork tenderloin. It was cryovac'd, half price, and the sell by date was 30 days away. I actually bought four and only one smelled like "don't eat me or you'll be sorry." It was a slightly different color too I didn't notice when I purchased it.
replacing it with some nitrogen. That's probably what you are smelling.
You did right, just like Demo said (below).Yea it was Tyson meat went back to Wally World. Couldn't wash the smell off it. First piece of bad meat I've got there.
Exactly.
Yep yep, sometimes some gassing goes on in cryovac. Give the pork a good rinse, let the air (and your nose clear) then give it another sniff. Here's where it gets somewhat complicated. If smell is gone, then no more worries. If it flat out smells bad, get rid of it (or take it back and complain). If it just smells a little different than normal, cut a small sliver, fry it up in a pan and take a nibble and see how it tastes.
