Is Plastic Number 7 Safe?

If you come across a plastic bottle marked with the number 7 and featuring the letters "PC," it indicates that the bottle contains bisphenol A (BPA). While all polycarbonate bottles are classified as number 7, not all manufacturers include the "PC" labeling. Additionally, not every plastic with a number 7 designation contains BPA. However, if the bottle is clear and rigid and labeled with the number 7, there is a possibility it may contain BPA.
