SÃO PAULO, BRAZIL — Brazilian flour millers are threatening not to buy wheat from Argentina if Brazil commercially approves GMO wheat imports from the country, Reuters said, citing the Brazilian Wheat industry Association (Abitrigo).

The millers along with a group representing bakers and others that use wheat are against processing GMO wheat from Argentina.

CTNBio is evaluating a request to approve the sale of genetically modified wheat produced in Argentina.

Abitrigo said the entire wheat supply chain is worried about the request for approval of GMO wheat here, and have concerns about the health of consumers.

“There is no country in the world that accepts the import of GMO wheat,” Barbosa said. “Brazil would be the first. We don’t want to be the guinea pigs.”

Brazil imports 60% of the wheat that is consumed domestically, with 80% of the imports coming from Argentina. Brazil could increase non-GMO imports from other nations, including Uruguay, Paraguay, the United States, Canada and Russia.
