"Risks of Deadly Amoeba Infections from Nasal Rinsing Devices"
The CDC has linked neti pots and other nasal rinsing devices to potentially deadly acanthamoeba infections, with 10 cases reported between 1994 and 2022, three of which were fatal. The FDA has long warned against improper use, such as using tap water, which can increase the risk of infection. Health officials recommend using boiled and cooled water or buying distilled or sterile water for nasal rinsing to prevent infections, and urge healthcare providers to educate patients on safe practices.
