Meat company included in embargo (5)
I believe the answer is:
bacon
'meat' is the definition.
(bacon is a kind of meat)
'company included in embargo' is the wordplay.
'company' becomes 'co' (abbreviation).
'included in' means one lot of letters goes inside another.
'embargo' becomes 'ban' (I've seen this before).
'co' going within 'ban' is 'BACON'.
(Other definitions for bacon that I've seen before include "Cured pig-meat" , "famous artist" , "Artist - meat" , "rasher" , "See 9" .)
