Controversial Liberal Senator Cory Bernardi's parliamentary inquiry into food certification - really, halal certification - has been receiving all sorts of wonderful and well thought out submissions from the public.

Mr Bernardi has long held fears about where the money paid for halal certification "ends up" - he has referred to it in the past as a "racket" - including whether it helps fund terrorist groups or religious activities in Australia.

He says he's keen for the inquiry to "establish all the facts" about certification. The Australian Crime Commission said last year it found no links between halal certification and the financing of terror groups.
