What's the Big Deal About BPA?

Whether you’re ordering new plastic containers for your restaurant kitchen or a new water bottle for personal use, you’ve probably seen products that brag, “BPA Free!” But what is BPA, and is it necessary to avoid it? BPA is short for Bisphenol A, a chemical that’s been used to make polycarbonate plastics and resins since the 1950s. The chemical started to get attention in the 1990s when customers began to ask, "Is BPA safe?" Since then, there have been several studies that have attempted to link BPA to health problems, but the FDA has concluded that a low level of BPA exposure is not harmful to humans. Despite this, the U.S. and Canada have banned baby bottles with BPA to prevent potentially negative effects in children, and many companies are voluntarily phasing out adult water bottles with BPA in order to reassure worried consumers.

What Plastics Contain BPA?

Although a certain amount of BPA is safe for daily human ingestion, consumers should be aware of which plastics contain BPA and other potentially harmful chemicals. Plastic is categorized by resin codes that tell consumers how to recycle the different types of plastic. The recycling number also corresponds to chemicals that the plastic is actually made with. It can be difficult to keep these numbers straight, so this list will help you sort out which plastics are safe for use in a variety of different situations.
