Does listerine mouthwash help control listeria?

Listerine mouthwash is not specifically designed to control or eliminate Listeria bacteria. While it may help reduce general oral bacteria and improve oral hygiene, it is not effective against Listeria, which is primarily a foodborne pathogen. Proper food handling and cooking practices are the most effective ways to prevent Listeria infections. If you have concerns about Listeria, it's best to focus on food safety rather than relying on mouthwash.
