On June 16, 2014 the American magazine Mother Jones reported on scientific findings of estrogenic chemicals migrating from BPA-free plastic products. In her article, journalist Mariah Blake summarized a recent peer-reviewed publication by scientists who had measured estrogen activity leaching from different brands of plastic baby bottles and other plastic containers, using in vitro assays (Bittner et al. 2014; FPF previously reported). The scientists tested 50 re-useable containers and exposed them to heat and UV radiation. More than three-quarters of the tested containers were shown to be positive for estrogenic activity, regardless of their plastic type. Notably, brand names of specific products are detailed, and the Mother Jones article gives an overview of selected products’ estrogenic activity before and after UV exposure.
