Iridescence is most commonly seen on:
- Deli ham
- Roast beef
- Corned beef
- Turkey
- Smoked meats
- Some fish
It is most noticeable when the meat is sliced very thinly and viewed under bright light.
Is Rainbow-Colored Meat Safe to Eat?
Yes—provided the meat is otherwise fresh and has been stored properly.
The rainbow sheen by itself does not:
- Mean the meat is spoiled
- Indicate bacterial contamination
- Affect taste or texture
- Change the nutritional value
Food safety should be judged by other signs, not by the rainbow colors alone.
