Unknown aetiology
Major cell involved is eosinphil
Usually noticed at slaughter - green muscle discoloration
May be caused by degenteration of Sarcocystis spp.
Grossly:
- Green discolored areas, well demarcated
- Mostly in muscles of back and thighs
Histologically:
- Massive eosinophil infiltration
- Muscle fibres may degenerate
- In old lesions - endimysial fibrosis, myofibre atrophy, some regeneration, lymphocytes, plasma cells, macrophages and few eosinophils
- Capsule may form
