Bisphenol A (BPA) has been the subject of much recent controversy due to reports that it can cause birth defects, impaired sugar control as well as other health problems in rodents. Â Bisphenol A is a synthetic organic compound that exhibits estrogenic effects. Â Every year, over 22 billion tons are produced and used primarily to make plastics. Â BPA can be found in baby bottles, food can linings, dental sealants and much more. Â On September 23rd, 2010, Canada became the first country to officially declare bisphenol A as a toxic substance. Â This is an administrative move that allows for future regulatory action should this be deemed necessary. Â There are no current plans to restrict the use of BPA other than in the production of baby bottles.
