Ziploc, a trusted household name in food storage, is facing a proposed class action lawsuit over allegations that its popular bags and containers release harmful microplastics when microwaved or frozen. Filed in the U.S. District Court for the Northern District of California, the suit claims that S.C. Johnson & Son, Inc., the maker of Ziploc, misled consumers by labeling its products as “Microwave Safe” and “Freezer” ready—despite scientific evidence suggesting that the polyethylene and polypropylene used in these products can release millions of microplastic particles under such conditions. These particles may pose significant health risks, including to the digestive, immune, and reproductive systems.
According to the complaint, consumers like lead plaintiff Linda Cheslow relied on these safety claims when purchasing Ziploc products for everyday use. However, studies cited in the case reveal that ordinary usage, such as microwaving leftovers or freezing meals, could result in dangerous levels of microplastic exposure. The lawsuit seeks damages for consumers and injunctive relief requiring S.C. Johnson to stop marketing the products as safe for microwave and freezer use unless they are reformulated or properly labeled. This case underscores growing consumer concern about microplastic contamination in food and the need for greater transparency in product safety claims.
