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

It’s also important to pay attention to the expiration date and consume the ham within a few days of opening the package. Leaving the ham exposed to air or storing it at higher temperatures can accelerate spoilage, leading to unpleasant odors and textures.

Determining when 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 of caution.

When purchasing deli ham, choose a reputable supplier and check that the product is within its expiration date. Opt for ham that is pre-packaged or freshly sliced in-store, and avoid meats that appear discolored or have an off smell.
