While there are no federal restrictions on BPA in food packaging, the government has set a guideline for safe exposure. Recent studies, however, show exposure to lower doses of BPA is associated with a wide range of adverse health effects, including various cancers, diabetes, and heart disease.

Consumer Reports tested a variety of foods for BPA -- three samples of 24 different products, mostly canned. Included were products from Campbell's, Del Monte, Green Giant, Hormel, Progresso, and others.

Outside lab tests found that many of the samples contained BPA levels that were higher, often much higher, than the level that Consumer Reports' experts believe could pose a safety risk, especially to children and developing fetuses.

It's important to note that levels of BPA can vary significantly even in the products tested. Consumer Reports tests were a small snapshot of the marketplace, so you can't draw conclusions about any one type of product or any particular brand.

You can do some things that may help minimize exposure:
--Ideally, choose fresh food over canned whenever possible.
--For products that children drink a lot, consider alternatives, such as powdered infant formulas and bottled or boxed juice.

The Food and Drug Administration is reassessing the safety of BPA and likely will announce the results of that review by the end of November. Meanwhile, the food industry has been waging a fight against BPA regulations and is backed up by the American Chemistry Council, which claims scientific evidence clearly supports the safety of BPA. Consumer Reports disagrees, saying BPA use should be banned from any packaging that comes in contact with food.
