A seafood canner in Washington state has become one of the few U.S. food processors to stop using metal cans lined with bisphenol-A (BPA). Vital Choice Wild Seafood & Organics, Bellamy, Wash., has announced that its salmon and other canned seafood will be packaged in BPA-free cans from now on.

BPA is a plasticizer that has caused controversy due to studies linking it with various forms of cancer. More than 90% of American food cans have BPA in their lining, and it’s practically the only viable choice for high-acid products like tomatoes. For lower-acid foods, alternatives exist, but at a premium of more than 2 cents a can.
