🌈 What That Rainbow Shine Really Is

🚫 When to Toss It

Skip the ham if you notice:

• A sour or rotten smell

• Slimy texture

• Gray, green, or black spots (not just a sheen)

• It’s been open too long or improperly stored

🧠 Bottom Line

That shimmering rainbow effect might look strange, but it’s usually harmless and common in deli meats. One of those moments where food science looks spooky—but isn’t.

Next time you see it, you’ll know: weird-looking doesn’t always mean unsafe.
