A farmer who campaigns against halal certification has made a video pointing out that Jewish synagogues aren't harbouring terror plots.

Kirralie Smith argues that consumers should be wary of the halal certification of common supermarket foods, which funds Islamic religious activity.

'The money raised by halal certification is funding mosques and Islamic preachers, in some cases who do promote messages of violence and death towards unbelievers,' she said in a Facebook video on Monday.

Farmer Kirralie Smith says halal certification is funding mosques that host radical preachers

Common food items like Cadbury chocolates are halal-certified and sold at supermarkets

The farmer from the New South Wales Mid-North Coast wants consumers to be aware that kosher products are primarily sold in Jewish stores while halal-certified foods are widely sold in major Australian supermarkets.

Major corporations like Cadbury chocolates, Kellogg's breakfast cereals and Sara Lee desserts pay third-party halal companies a fee to certify that they contain no traces of pork or alcohol, making them permissible in Islam.

Secular Muslims and liberally-minded Islamic scholars, including Adelaide Shia Sheikh Mohammad Tawhidi, argue that halal-certified goods shouldn't be imposed on non-Muslims.

Ms Smith, who ran as a Senate candidate last year with the right-wing Australian Liberty Alliance, is concerned that consumers are unwittingly funding mosques that harbour extremist preachers.

'I've never heard a rabbi preach 'death to democracy or kill the infidel'. However, there are many imams in Australia and around the world who have preached these very things,' she said.

'Synagogues in Australia are not preaching sermons of hate towards Westerners or unbelievers.

'They are not radicalising their youth with messages of violence and death.'

Ms Smith has recently joined Liberal defector Cory Bernardi's Australian Conservatives party.

In April, The Project's Waleed Aly ate a non-halal Lindt Easter bunny live on air to mock One Nation leader Pauline Hanson's call for Australians to boycott halal foods at the supermarket.
