I'm not sure, but I think I read that this is the biggest concern with highly acidic products like tomatoes, and with cans that have been stored a very long time. I recall one poster saying that if things are to the point that his family is eating years old canned goods, he ain't much worried about some chemical that might be in the can lining.
IIRC, Nalgene changed their formula a little while back,eliminating BPA from their water bottles . Big whoop,I still use an old Nalgene bottle at work every day.

If you're concerned, the obvious solution is to can your own food. You might also do a little research, it's possible that some companies have eliminated BPA from their cans since this became news.
