Processed meat not wild (4)
I believe the answer is:
tame
'not wild' is the definition.
('tame' is the opposite to 'wild')
'processed meat' is the wordplay.
'processed' is an anagram indicator.
'meat' anagrammed gives 'TAME'.
(Other definitions for tame that I've seen before include "Flat" , "Restrained" , "Domisticated with meat" , "Not exciting; domesticate" , "Submissive -- pedestrian" .)
