I cut into my chicken breast and found this neon green flesh — is it radioactive?

Can Cooking Make the Green Color Safe?

Cooking poultry properly is essential for controlling harmful bacteria, but cooking should not be used to “fix” meat that already appears spoiled.

The USDA recommends cooking chicken to a minimum internal temperature of 165°F (74°C), measured with a food thermometer.

Importantly, reaching 165°F addresses microbial safety; it does not mean that every unusual-looking piece of meat should be eaten.

If the product appears spoiled or otherwise abnormal, discard it rather than trying to rescue it through additional cooking.

What Should You Do If You Find Neon-Green Flesh?

If you encounter a small, localized green area inside an otherwise normal chicken breast, it may be related to a muscle abnormality rather than contamination.

But if you’re unsure what you’re seeing, the safest approach is to avoid eating the questionable portion and contact the retailer or producer, particularly if the discoloration is extensive or accompanied by an unusual smell or texture.

Take a photograph of the affected area and keep the packaging and lot information if you intend to report the problem.

Final Thoughts

That shocking neon-green color can certainly look radioactive, but green chicken flesh is not evidence that the meat contains radiation.

A localized green area can be associated with changes in chicken muscle, while green coloration accompanied by unpleasant odor, sliminess, or other spoilage signs is a reason to discard the product.
