From U.S. PIRG:
Microwave popcorn is a staple snack, and a reliable presence at after-school homework sessions and family movie nights. Unfortunately, research shows that the bags microwave popcorn comes in are almost always laced with toxic PFAS chemicals — which can cause devastating health effects.
We’re pushing to ban PFAS chemicals in food packaging, but in the meantime, here are a few things to know:
PFAS chemicals are linked to serious health problems, including cancer.
Studies indicate that two kinds of PFAS chemicals — PFOA and PFOS — can cause tumors, reproductive and developmental issues, liver and kidney problems, and immunological effects in lab animals. Findings also linked the chemicals to low infant birth weights, cancer and thyroid hormone disruption.1 These studies don’t mean that if you eat microwave popcorn, you’ll automatically be stricken with these health effects. But they do suggest you’re taking a risk — an unnecessary one at that — when you eat it.
Every microwavable popcorn bag tested in 2017 came back positive for PFAS.
In 2017, the Center for Environmental Health tested a range of microwave popcorn brands sold at dollar stores. Every brand the group purchased tested positive, including Act II, Orville Redenbacher’s, Pop Secret, Clover Valley, Lowrey’s, Regal Cinemas and Pop Weaver.2
Because of the ubiquity of PFAS-laced popcorn bags, we recommend making your own.
If you love popcorn, but don’t want to risk exposure to toxic chemicals, you can still buy non-microwavable popcorn or make your own at home. According to renowned food writer Mark Bittman, all you need is corn oil, popping corn, butter and salt.3 And it only takes 10 minutes.
We’re working to ban PFAS chemicals so we don’t have to avoid our favorite snacks, and we’ve already had real success.4 Our advocates in Washington state recently celebrated the passage of a landmark bill that bans the use of paper food packaging products containing PFAS chemicals.
