June 13/University of Missouri -- A new study shows exposure to a chemical commonly found in food containers has been underestimated.

The study by University of Missouri suggests people should pay more attention to their repeated exposure to BPA.

MU scientists looked at daily diets, not just single exposures to the chemical as previous tests did.

BPA is Bisphenol-A, a chemical found in thousands of household products and is linked to breast cancer, heart disease, diabetes, male infertility and other health problems.

The chemical is not limited to children's products, it is also used in the linings of metal cans, cash register receipts, and even the plastic water bottles we drink out of.

Scientists from the University of Missouri found exposing mice to BPA through their feed significantly increased the active form of the chemical.

More than 8 billion pounds of BPA are produced every year, and more than 90% of U.S. residents have measurable amounts of BPA in their bodies.

States across the country are moving to ban the chemical in children's products and in 2010 the U.S. Food and Drug Administration said it has concerns about the chemicals potential effects on brain development of fetuses, infants and children.

However, many say it is hard to assess the dangers of BPA because people are exposed to the chemical in a variety of ways

Studies show adults and children can reduce their BPA exposure by eating more fruits and vegetables.

Baby bottles containing BPA currently are banned in eight states, New York, Connecticut, Wisconsin, Washington, Maryland, Massachusetts, Vermont and Minnesota.

Connecticut is the first state to ban thermal printer paper register receipts that contain BPA.
