Is melamine in dishware crossing into babies during pregnancy?
Yes. Melamine moves across the placenta and disrupts steroid hormones there.
What's actually in it
Melamine is the hard plastic in unbreakable plates, bowls, and serving spoons. The factory makes the resin from melamine and formaldehyde. Heat, acid, and abrasion let small amounts of melamine leak into food. Microwaving melamine speeds the leaching.
What the research says
A 2026 study in Environ Sci Technol went past the well-known kidney effects of melamine. The team showed melamine crosses the placenta and changes steroid hormone production in the placental tissue. Steroid hormones are how the placenta keeps a healthy pregnancy going.
Skip melamine for hot or acidic food. Plain ceramic, glass, or stainless steel are the safest plates. Bamboo or wood salad bowls work for cold food. For kid plates, look for silicone or stainless rather than melamine. Never microwave melamine, even if the back says "microwave safe."
