BPA is an abbreviation for Bisphenol A, a building block of many plastics. In recent years, the government questioned the safety of BPA for consumers, giving rise to the “BPA Free” movement in plastic water bottles and food containers. Regulatory authorities have more recently concluded that consumer exposure levels to BPA are very low and therefore do not pose a risk. Still, many manufacturers tout their bottles and containers as BPA free to ease consumers’ minds.
