Chobani markets its Greek yogurt as “real” and “natural,” but one anti-GMO group doesn’t think that it’s enough.

The group GMO Inside released a statement last week demanding that Chobani step up to the plate and stop using milk from cows that eat genetically modified feed.

"Chobani has an opportunity to be a leader amongst meat and dairy companies by listening to its customers and ensuring its cows are given non-GMO food,” GMO Inside Campaign Director Elizabeth O'Connell said in a news release.

The group urged Chobani customers to sign a petition or contact Chobani’s CEO, Hamdi Ulukaya.

Chobani responded to the media buzz surrounding the group's request, explaning the complexities of ensuring feed to its 78,000 cows across 875 farms is 100 percent GMO-free. Chobani noted that there is no universal dfinition of GMO-free milk, and also explained why they decided not to pursue USDA Organic certification.

"But please know that our team is dedicated to addressing GMOs. We’re currently navigating its complexities, specific to dairy, knowing that teamwork from our farmers and industry is necessary," Chobani wrote.

But is using milk from cows fed non-GM feed what Chobani customers want? Many of Chobani’s customers made it clear that GMO Inside doesn’t necessarily represent their opinions.

“I'm certainly not interested in purchasing something labeled as Non-GMO. I've done my research and I don't believe that GMO crops are something that I should be worried about. And I am really not concerned with the dairy products made with milk from cows that may or may not have had part of their diet come from gmo crops. If you want to start an organic line, go for it. I'm perfectly happy with the product you have now,” one person commented to Chobani’s response.

“I think Chobani yogurt is great. It does not have to be GMO-free. Keep doing the good job you are doing and thanks for standing up to the activists who are trying to tell you how to run your business. I am still trying to wrap my head around Mustafa eating that much yogurt every day! He might live to be 120,” another Chobani fan wrote.
