An Oral B mouthwash is being recalled after unusual amounts of microbes were found in it.
Oral B parent company Proctor and Gamble says it is recalling the Pro-Health tooth and gum care mouth rinse as a precaution.
It says the microbes in the mouthwash could cause infection to people with a severely weakened immune system.
People who have bought the product should not use it, and are advised to ring Oral B for a refund.
