Bisphenol A (BPA) Overview & Updates. BPA (Bisphenol A) is a chemical used in certain food contact materials and first approved by FDA in the early 1960s. In recent years, concerns have been raised about BPA's safety. In August 2008, FDA released a draft report finding that BPA remains safe in food contact materials.
A BPA is an agreement (NOT a contract) between the Government and a contractor that sets the stage for the Government to buy items quickly. All the conditions of sale are negotiated when the BPA is initially established, but contract formation does not occur until each individual call or order is placed.
