When the meat first comes in contact with the air, it turns red/pink, according to theU.S.
It’s the same phenomenon that turns your avocado or sliced apple brown.
And oxidized food isn’t necessarily bad food, at least not right away.

First, check the expiration date.
Next, smell it.
Last, feel the texture.

If it is slimy or greasy in feeling, toss it.
That could indicate bacteria growth and spoilage.
Packaged meat might have a darker purple-red color, and that’s okay.

That just means it hasn’t been exposed to much oxygen because of its vacuum-seal packaging.
Also check that the packaging doesn’t contain excessive liquid and that it’s properly sealed with no holes.
It can safely be stored up to three to four months this way.
Plan to use it in the next few days?
