discolored breast meat

[bigdog]

I recently butchered 26 cornish X and 2 had a yellowish green patch in the strip of breast meat closest to the keel of the breast bone, only on 1 side. It was about 1/2 inch wide and 1 inch long. The birds all appeared healthy. None of the batch I ordered had died. The meat looked normal other than the color. I cut out/threw away that hole strip. Any one have any idea what it might have been?
Thanx

I've seen that before, and it's rather alarming. From what I've been told, it could be anything from a bruise to a tumor. On the rare occasion you get that, I think cutting that part out and keeping the rest is fine.

Google "Green muscle disease". There are a couple of PDF files from big producers such as Aviagen, some with photos, that show this syndrome. The condition is caused by the muscle actually dying and beginning to decompose.
