20 Sep 2018 --- Bisphenol A (BPA) alternatives used in “BPA-free” bottles, cups, cages and other items have been found to cause reproductive problems in mice by researchers at Washington State University. “BPA-free” or not, plastic products that show signs of damage or aging cannot be considered safe, the researchers warn. Patricia Hunt, a researcher in the lab, further tells PackagingInsights that it is not possible for consumers to determine if a product contains bisphenols, but states that “new recycling codes or other mandatory labeling that would allow consumers to make educated decisions would be ideal.”
