Meat company in embargo (5)
I believe the answer is:
bacon
'meat' is the definition.
(I know that bacon is a type of pork meat)
'company in embargo' is the wordplay.
'company' becomes 'co' (abbreviation).
'in' indicates putting letters inside.
'embargo' becomes 'ban' (I've seen this before).
'co' put inside 'ban' is 'BACON'.
(Other definitions for bacon that I've seen before include "Food that can be streaky" , "Cured back or side of pork" , "The meat to bring home for success" , "Cured pig-meat" , "Food - essayist - painter" .)
