It's not consumed in June at encampment (7)
I believe the answer is:
uneaten
'it's not consumed' is the definition.
(I've seen this before)
'in june at encampment' is the wordplay.
'in' indicates a hidden word.
'UNEATEN' is hidden within 'june at encampment'.
(Other definitions for uneaten that I've seen before include "not chewed" , "Make an outline of" , "Left on the plate" , "Not taken in" , "still on the table?" .)
