You're entirely right to remember the Blue Bell ice cream recall and how it started with a few products and ballooned. While that's rare, it can happen.
I'm on the FDA e-mail list for messages about recalls, and I get them almost daily during the weekdays (it does include medical product recalls, not just food, I should note--but most of it's food recalls including pet foods which seem to be candidates for contamination!).
In your shoes I would pitch the chicken just for safety's sake. Remember -- by the time the FDA is involved in a large, public recall, or even by the time a manufacturer itself is doing a recall even without FDA involvement, the product is already usually widely distributed, and reports of possible illness can take quite a long time to reach authorities who then take time to report those incidents to the manufacturer or the FDA. That's why things happen like the Blue Bell recall where products on the recall list gradually kept increasing over time.
Better to dump the product than to serve it later and worry about someone getting sick. Even if no one gets sick -- the worry would be bad enough, for me.
If you want to sign up for the FDA recall e-mail alerts, you can do so at:
http://www.fda.gov/Safety/Recalls/default.htm
Look down the page for the link that says, "Sign up to receive recalls...alerts"
Getting the alerts has helped me avoid possibly tainted products twice in the past couple of years so that's worthwhile, to me. Most stuff is fine, but when something isn't, I prefer to know as soon as I can.
