In response to the claims made by Kirralie Smith and HalalChoices, officials from the Australian Criminal Intelligence Commission have stated that the commission has been on "heightened lookout" for links between halal certifiers and terrorism since the issue surfaced last year, but has "not found any direct linkages", an inquiry has heard. Furthermore, a Senate inquiry into food certification asserted that there was "no link" between the religious approval process and extremist groups.[19] It recommended that the federal government increase its oversight of domestic halal certifiers to address fraudulent conduct in the sector.[20] It said that it had heard, "credible reports suggesting that the lack of regulation has been unscrupulously exploited". In tabling the report, committee chairman Sam Dastyari said, "Some certifiers are nothing more than scammers."[21] The committee recommended a single halal certification authority.[21] The committee in recommending clearer labelling, specifically referred to the need for meat processors to label products sourced from animals subject to religious slaughter.[22]
