It’s understandable that you’re concerned about meat that appears shiny and rainbow-like, as this is not something typically seen in fresh meat. There are a few potential explanations for this unusual appearance, but most of them are relatively harmless. Here are some common reasons for this phenomenon:
1. Natural Meat Reflection (Iridescence)
- What It Is: Sometimes, fresh meat, particularly beef, pork, or lamb, can develop a shiny, rainbow-like appearance when light reflects off the muscle fibers. This effect is called iridescence, and it’s a natural optical phenomenon that happens due to the way light interacts with the meat’s fibers, moisture, and fat.
- Why It Happens: The meat might have been exposed to light in a certain way that causes this reflection, similar to the effect you see on the surface of a bubble or the feathers of some birds.
- Is It Safe? Yes, iridescence is generally harmless, and the meat is typically still safe to eat. Just ensure the meat is fresh, has been stored properly, and doesn’t have any off smells.
