I just called my son's Cf coordinator to tell her "Listerine Agent Cool Blue" mouthwash was recalled 04-12-07 and she didn't know. I wanted to make sure everyone knew. It doesn't contain a preservative that prevents b cepacia from contaminating it. Of course, my luck. that's the mouthwash my kids use. My 10 yr old has Cf. He didn't have b cepacia 2 mnths ago and hopefully still won't. If you go on line you'll find info under "Agent Cool Blue"
