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

to toss deli ham depends on a combination of visual, olfactory, and tactile assessments. If the ham shows any signs of discoloration, mold, or off-putting odors, it should be discarded immediately. A slimy or sticky texture is another indicator that the ham is no longer safe to eat.
Conversely, if the ham’s only unusual feature is its iridescent sheen, and it otherwise smells and feels fresh, it is generally safe to consume. Trusting your senses is key, and if you’re ever in doubt, it’s best to err on the side
