In fact, they've changed in just the time since this article was written, since I did all my canning the way Amy does in this piece. New recommendations for water bath canning are for nearly an hour!

If your jars sealed, I myself would NOT reprocess them; they'll lose some quality. I would eat them sooner rather than later. (Frankly, I wouldn't be that worried at all, but canned tomatoes don't last long around here.) But if you're really worried, and considering current recommendations I don't blame you, you can reprocess them in their current jars as long as those jars sealed. If the jar did NOT seal and it's more than 24 hours after you canned it, throw it out. It's bad.

Off to edit the article now.
