The lot number is listed directly beneath the date on the bag. If your bag's expiration date falls within the dates that were pulled, check the lot number to see if it matches any on the list. I dunno how other retailers work, but my store is happy to take back any bag anyone is concerned about, whether it is on the list or not.

This was a pretty small thing, all in all. My store had 16 bags out of hundreds we keep on the shelf.
