[QUOTE="TerryJ2, post: 150832, member: 3419"] Yes, I remember this. But in regard to cancer, not behavior. Anything is possible, though. It is basically a very bad idea to microwave anything in plastic, as the heat will cause the plastic to degrade on a molecular level and start floating around in the water. Plastic is known to be carcinogenic and some plastics are more carcinogenic than others. Never BOIL baby forumla in plastic in the microwave. WARM it in a glass container to slightly above rm temp and then transfer it to a plastic baby bottle. (It stands to reason you wouldn't give boiling water to a baby anyway.) Here's a good explanation, and a link to the same article: [URL]http://www.bisphenol-a.org/whatsNew/20080131.html[/URL] Although this study was small in scope, the finding of no difference between old and new bottles is good news. A persistent myth about polycarbonate bottles is that they degrade with use. That myth was not confirmed in this study. Even a nine year old bottle was no different from the new bottles. The finding of increased migration into boiling water is not news at all. It is a well known general phenomenon that migration levels increase with increasing temperature. That phenomenon has been confirmed in many earlier studies of migration of bisphenol A from polycarbonate bottles. The further finding that migration into room temperature water remained elevated in bottles previously filled with boiling water is only part of the story.
