Ziploc Faces Class Action Lawsuit Over Microplastics in 'Microwave Safe' Products
Overview of the Lawsuit
On April 25, 2025, a class action lawsuit was filed in the U.S. District Court for the Northern District of California against S.C. Johnson & Son, Inc., the parent company of Ziploc. The plaintiff, Linda Cheslow, alleges that Ziploc's marketing of certain products as "microwave safe" and "suitable for freezer use" is misleading, as these products may release microplastics under extreme temperatures.
Allegations of Misleading Marketing
The lawsuit contends that Ziploc products made from polyethylene and polypropylene, when used in microwaves or freezers, can degrade and release microplastics into food. Despite being labeled as safe for such uses, the plaintiff argues that consumers were not adequately warned about these potential risks.
Health Implications of Microplastics
Microplastics are tiny plastic particles less than five millimeters in size. Research has detected their presence in various human tissues, including blood and organs. Studies suggest that microplastics can disrupt hormones, damage DNA, and may contribute to illnesses such as cancer and cardiovascular disease.
