Food recall cause (1,4)
I believe the answer is:
e coli
'food recall cause' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for e coli that I've seen before include "cause of ill-feeling" , "Nasty bug" , "cause of illness" , "Gut bugs" , "Some types of this bacterium are toxic" .)
