Far more leeching of BPA occurs in ready-to-serve canned liquid formula than in baby bottles. According to the Environmental Working Group (EWG) and the FDA, testing has shown that the BPA that leaches into formula and other canned goods subjects babies and pregnant women to harmful exposure. The EWG has calculated that 1 out of 16 children fed ready-to-eat formula from steel cans have exposures to BPA that exceeds doses which are harmful in animal studies. The National Institute of Health (NIH) has also expressed concerns about infant exposure to BPA. A panel of 38 BPA experts expressed grave concerns related to human exposure to BPA that are at or above levels that have caused harm in animal studies. The Center for the Evaluation of Risks to Human Reproduction (CERHR) has concluded that brain development and behavior can have adverse affects when there is infant exposure. This suggests that parents should avoid exposure to BPA until there is futher information.
