 Philips is one company, Handicraft is the other. It's the maker of the brand Dr. Brown's Baby. The plaintiffs allege that both companies knew their baby bottles were made using microplastics that can leak when heated, seeping directly into the baby's food or drink. The suit also alleges that both companies were aware of the dangers but still labeled their products BPA-free. The dangers of microplastics are still being examined, but some environmental groups say their ingestion has been proven to be dangerous, especially in small children. Sherry Preston, ABC News.
