Pulled deli ham from the fridge and noticed a rainbow-like shine on the slices. Is that normal?

What’s happening:
It’s called iridescence. When meat is sliced, light reflects off the muscle fibers and fat in a way that creates a rainbow effect (basically light diffraction). It’s common on ham, roast beef, corned beef, and turkey, especially under fridge or LED lighting.

When it’s fine:

  • Smells normal (just “meaty,” not sour)

  • Feels normal (not slimy or sticky)

  • Color underneath looks pink/normal for ham

  • Within the “use by” date and kept cold

When to toss it instead:
