A new study released on Tuesday has identified the actual amount of BPA that is many of the foods Americans eat. The study, which is published in the peer-reviewed journal Environmental Science & Technologyis a "market basket" study that examined meat, poultry, fish, fruit and vegetables purchased at supermarkets. The scientists also included canned and packaged food because the containers include BPA in their epoxy resins.

To measure the exact amounts, researchers at Eurofins Scientific, an international group of laboratories that specializes in analyzing food and persistent organic pollutants, isolated the BPA and quantified it using high-resolution gas chromatography and low-resolution mass spectrometry.

They found BPA in many foods, with canned foods generally having the highest BPA concentrations. Cans of Del Monte fresh cut green beans had the highest BPA concentrations in the study. The three cans tested contained between 26.60 and 65.00 nanograms of BPA per gram of food. (As a reference, the Environmental Protection Agency or EPA has set a safety limit of 50 micrograms of BPA per kilogram of body weight per day. Since it takes 1,000 nanograms to equal 1 microgram, the foods in the study came in well below the EPA's limit.  Still, many health experts argue that this number is arbitrary and too high for human consumption levels.)

Other sources of BPA included fresh turkey and foods with plastic packaging, such as Chef Boyardee Spaghetti and Meatballs, which had higher BPA levels than cans of the same food.

Foods with surprisingly low levels of BPA include SPAM (just because it's gross, I expected it to be higher) with .32 nanograms of BPA, Hunts canned tomato paste with less than .20 nanograms of BPA, and various of varieties of infant formula (Enfamil Premium LIPIL Infant Formula Milk Based came in the highest with measurements between .97 and 1.24 nanograms of BPA while Similac Advanced Infant Formula and Infant Soy Formula both had less than .20 nanograms of BPA.

This study was an eye-opener for me, I mean fresh turkey? Who knew? But I would love to see a much more extensive list of products tested like juice in boxes, bottles, and cans; fresh vegetables in packaging compared to frozen or canned; and baby food.
