Mouthwash is supposed to kill bacteria so it's probably not a good thing when a mouthwash is contaminated with it. Hydrox Labs is recalling alcohol-free mouthwash sold under the Cardinal Health name. It's only dangerous to people with weakened immune systems or chronic lung diseases. The mouthwash has a lot number of 26230 and was primarily sold in hospital person hygiene kits. Cardinal Health will notify customers.
