A new study found traces of phthalates in store bought mac and cheese products, specifically in the cheese powders. Phthalates are chemicals that keep plastics flexible, transparent and durable. Past research has linked these chemicals to lower sperm count and hormone disruption.
The study, which was conducted by The Coalition for Safer Food Processing & Packaging, found that 29 out of 30 packages tested had contained the chemicals. Although phthalates aren’t intentionally added to the food, they can slip in pretty easily through the process. Since discovering this, the coalition has launched a #KleanUpKraft petition to get rid of “toxic industrial chemicals” completely. Although these chemicals have been found in all kinds of store bought mac and cheese, including organic labels, Kraft sells the most.

In the letter, the coalition explained that young children’s and pregnant women’s number one source of phthalates is through food.
Kraft released a statement to Time explaining that they don’t add phthalates to any of their products. “The trace amounts that were reported in this limited study are more than 1,000 times lower than levels that scientific authorities have identified as acceptable,” the company stated. “Our products are safe for consumers to enjoy.”
