Green fat on frozen pork butt

Have had a couple of butts in the freezer since last fall. When I recently checked on them, they featured a lot of fat that had turned quite green. They have been continuously and thoroughly frozen since purchase.

What say you? I know the general consensus is to toss when questionable, but I also don't want to do so unecessarily; butts are hard to come by in my area and given the consistent freezing, I fail to see how this could be spoilage and am therefore inclined to proceed. 


  • @Woodchunk: Thanks. Had seen that, but is it less than conclusive.

    I agree, it was. The one common thing I found was this is most likely caused by light or air. In the freezer so no light so maybe a tiny hole in the package or on the seam. 

    First st time I have seen this. Sounds like a preservative thing. Is it ok to eat, that's the ?

    So, how did it smell when thawed?

    Haven't yet thawed. I'm just planning ahead. 

    I agree that a sniff test could be somewhat indicative though.

    I did not weigh in on this when you first posted but did have an opinion I just kept to myself as it is not based on any first hand experience. But, since you asked again, personally, I would toss it. I don't see any reason to take a chance. I had to visit the ER a few years ago for kidney stones and that little trip wound up being close to $1000. Now, I don't know if this would result in any food borne illness that would require an ER trip, but again, I would not take the chance.
    It could very well be it is nothing and you will be fine. I hope whatever you choose, you don't get sick over it.

    I wouldn't eat it. It may be fine, but I wouldn't chance it. Let us know what you decide to do.

    Had the same thing on a Costco rack of pork last year.  When thawed it had that sulfer smell that I couldn't get to go away after a couple of rinses.  I ended up throwing it out under the better safe than sorry theory.

    It is probably just the blood/liquids at the surface of the meat that oxidized.  Thaw it, rinse it and trim if required but I don’t see why it would not be good.

    Maybe it's very new cheese... or very old meat. =)

    I hate it when I go to the kitchen for food and all I find are ingredients!

    Food doesn't go bad when frozen.  Looks like freezer burn.

    Presumably you already know your freezer didn't fail during the period it was frozen.  Minerals will migrate through frozen meat.  I'm guessing this is similar to the green ring around an egg yolk after boiling. It's definitely not biological if it occurred while frozen.

    If your assertion that there was never a freezer loss of power, I agree with Nola.  Trim, cook eat if there are no bag leaks or bad smell.
