Safe to have (6)
I believe the answer is:
edible
'safe to have' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for edible that I've seen before include "Good enough to eat" , "Fit to be used as food" , "Fit to be eaten" , "Belied (anag)" , "Able to be eaten" .)
