(CNN) - Is Ben & Jerry's popularity melting?
The Organic Consumers Association reported that 10 out of 11 samples of the Vermont-based company's ice cream had traces of glyphosate, a key ingredient in herbicide.
The OCA is calling for organic and natural food stores to dump the products unless the company goes organic.
In a statement, the group said "Ben & Jerry's falsely advertises its products as 'natural' and its brand as 'sustainable' and 'socially responsible.'"
Among the flavors the glyphosate was reportedly found in: Cherry Garcia, Half-baked, Phish Food and Peanut Butter Cookie.
The World Health Organization's International Agency for Research on Cancer deemed glyphosate was a "probable carcinogen" in 2015.
In wake of the news, some of its customers were bashing the company on its Facebook page, with one person writing, "You are my favorite ice cream brand, but I CANNOT buy your ice cream again until it no longer comes up positive for MONSANTO'S GLYPHOSATE."
The company has not responded to a request for comment.
Ben and Jerry's details its business practices on its website, including using non-GMO ingredients for most of its products.
