A recent test by rtings.com reveals that nonstick cookware can shed particles even when the coating appears undamaged. The study focused on PTFE (polytetrafluoroethylene) coatings, commonly found in nonstick pans. Researchers subjected various pans to rigorous use, including repeated heating, cooling, and scrubbing, simulating years of typical home use.

Contrary to the assumption that visible wear is a prerequisite for particle shedding, the tests demonstrated that microscopic damage, not always apparent to the eye, can lead to the release of PTFE particles. This finding raises concerns about potential ingestion of these particles, although the long-term health effects are still debated among scientists and regulatory bodies.

The study emphasizes the importance of proper care to extend the lifespan of nonstick cookware and potentially minimize particle release. Recommendations include avoiding high heat, using non-metal utensils, and hand-washing instead of using a dishwasher. The rtings.com team conducted 1000 cycles of use on each pan, utilizing various cooking methods and cleaning techniques to assess durability and particle shedding.
