High Levels of BPA found in Canned Vegetables
Canned vegetables, regardless if they are labeled "organic" or not, have been found to contain high levels of Bisphenol A (BPA) -- an estrogen impersonator -- that is transmitted to the food from the can lining. According to as study released this week by the US based National Workgroup for Safe Markets, 50 cans that were collected from different locations showed BPA measurements up to 77 parts per billion (ppb), and a DelMonte green beans can measured 1,140 ppb.
This represents a drastic increase since FDA testing on 6 cans in 1996 only detected 16 ppb. Despite the rise in contamination, the FDA is still deliberating if there is enough evidence to warrant regulation. The Natural Resources Defense Council is seeking to introduce legislation that will strengthen the 1976 Toxic Substances Control Act to cover BPA contamination and any replacement can liners.
BPA received the 2009 "Toxie" award as the most dangerous unregulated chemical contaminating food. Although companies like General Mills are voluntarily switching some products to BPA free cans, consumers should be aware that only fresh, frozen or boxed vegetables are currently free of BPA contamination.
