Then came the report of brain-eating amoeba.
Two people died from the amoeba Naegleria fowleri after irrigating with contaminated tap water using a simple irrigation device called a neti pot. They developed meningitis with severe headaches and neck pain. There’s really no effective treatment.
Now everyone wonders, is irrigating with a neti pot safe? Is any sinus irrigation considered safe?
The answer is a resounding yes, if you follow the FDA suggestions by:
- Using distilled or sterile water you buy at a store.
- Boiling tap water for three to five minutes.
- Using a water filter with a pore size of 1 micron or smaller.
Before I read the FDA recommendations, I thought salt would kill the ameboae, but the FDA doesn’t mention it, so I no longer deem that a safe way to go. I’d still use a half-teaspoon of salt per cup of warm water but just because it seems to work better and not irritate the nasal lining as much. Just don’t depend on it alone to kill the amoebae.

In case you’ve forgotten your high school science, an amoeba (alternate spelling is ameba) is this microscopic, one-cell organism that lives in water. Its way of travel has always reminded me of the colored oil that moves around in those lava lamps.
One other thing.
The Naegleria fowleri amoeba is nothing new. It lives in warm, fresh water such as lakes, rivers, and hot springs. And just like with the neti pot, people have died from getting contaminated water up their nose. Of course, like the nasal-irrigation route, getting it this way is very rare, but deadly.
To avoid it, don’t go underwater if you can help it, and hold your nose if you do. Also, don’t sit around in the shallow water and stir up sediment, where it likes to reside.
What about you? Have you stopped sinus irrigation or changed your way of doing it since this report came out?
