The Senate voted 35 to 1 Thursday to ban the sale of plastic baby bottles, food containers, and sippy cups that contain Bisphenol-A.

The chemical helps make plastic shatter-proof and is used as coating on the inside of almost all food and beverage cans. A growing body of scientific research shows the chemical may be harmful to humans, especially infants and small children.

The bill now goes back to the House because the Senate did not approve an amendment, which requires all food containers made with the chemical to come with a warning label.
