What It Is: In some cases, the packaging, especially vacuum-sealed packages, can cause meat to retain more moisture, which can give it a shiny or glossy appearance. This can sometimes create a rainbow effect on the surface, especially if the meat has been exposed to certain lighting.
Why It Happens: The moisture on the surface of the meat can reflect light, causing the rainbow effect. This is more common in meats that are packaged right after slaughter when they are still quite moist.
Is It Safe? Yes, as long as the meat hasn’t been in the packaging for too long or hasn’t reached its expiration date, it’s typically still safe to consume.
3. Oxidation and Spoilage
What It Is: Spoiled meat can sometimes have an unnatural sheen or a strange, rainbow-like discoloration. This is usually due to oxidation or bacterial growth on the surface of the meat.
Why It Happens: If the meat has been improperly stored or is nearing its expiration date, bacteria can start to grow and cause changes in the texture, color, and appearance of the meat. This might include a rainbow-like sheen.
Is It Safe? If the meat smells off or has an unusual texture, it’s best to discard it. Spoiled meat can carry harmful bacteria that cause food poisoning.
