The Utne Reader revealed earlier this week that most commercially available canning jars contain a small amount bisphenol A, better known as  BPA. BPA is present on the wax-sealed jar lids of Ball, Kerr and other manufacturers.

Via Utne Reader and Organic Gardening whose Winter 2009-2010 issue features an article on BPA in canning supplies:

“If the lid doesn’t contact the food, it’s not a problem,” says Frederick vom Saal, a biological sciences professor at the University of Missouri-Columbia. But that’s unlikely to be the case, so he recommends using a BPA-free product. Organic Gardening suggests Weck brand canning jars, which have glass lids.

If you're planning on participating in one of the SF canning projects, from Canning Across America to Yes We Can, be sure to ask what kind of jars they'll be using.

Thanks to the increased interest in canning and preserving that this news got out. Happy canning...and if you've never canned I'll have more info on local canning classes so subscribe to the email or check back.
