In response to growing consumer anxiety, California lawmakers are considering enacting what could be the first statewide restrictions on bisphenol A, a chemical found in plastic baby bottles and infant formula cans.

The bill would require that all products or food containers designed for children 3 years and younger contain only trace amounts of the chemical.

Bisphenol A can disrupt the hormonal system, and there is concern that the chemical could cause changes in behavior and the brain.

The U.S. Congress is also considering legislation to ban it in children’s products, and Canada has announced that it intends to ban the use of the chemical in baby bottles.
