FAQs: Processing • I processed my chickens and they looked fine, but when I cooked them and went to carve the chicken for dinner, there was green disgusting meat in the breast. What is this?
Green Muscle Disease
BROILER QUALITY: Green muscle disease • Also called Deep Pectoral Myopathy • A non-infectious, focal bi- or uni-lateral necrosis of the deep pectoral muscle (breast tenderloin) • Initially noticed in fast growing turkeys • Recently observed sporadically in heavy broilers destined for deboned breast meat production – Lesions observed during processing indicate that birds are either genetically predisposed to this condition or some "stressor" acts as a trigger this condition during the pre-slaughter phase
