A recent report by the Centers for Disease Control and Prevention (CDC) has highlighted a potential health risk associated with the use of neti pots, devices commonly used for nasal rinsing to alleviate symptoms of allergies and respiratory conditions. The CDC’s alert points to an association between neti pot use and infections caused by Acanthamoeba, a type of amoeba found in various natural environments, including lakes and soil. This amoeba can cause severe, even fatal, brain inflammation known as amoebic meningoencephalitis.

This concern arises at a time when neti pots have gained popularity in the United States as a method to relieve respiratory ailments. Dr. Julia Haston from the CDC underscores the importance of being informed about the risks involved in using these devices for nasal irrigation. A study cited by the CDC, involving 10 patients, has confirmed a link between nasal rinsing practices and infections, attributing them to the use of untreated tap water in neti pots.

The primary issue lies in the presence of harmful microorganisms, like Acanthamoeba, in tap water that is safe for drinking but poses risks when used in humidifiers or for nasal rinsing. To prevent such infections, the CDC recommends utilizing boiled, sterilized, or distilled water in neti pots. This guidance aims to raise awareness about the safe use of nasal irrigation devices to protect users from potentially life-threatening conditions associated with improper water treatment.
