Dead meat (7)
I believe the answer is:
carrion
'dead meat' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for carrion that I've seen before include "Food for crow" , "Dead flesh (for e.g. crow)" , "Cor! Rain! (anag.)" , "Decaying flesh of dead animals" , "Rotting dead body of an animal" .)
