Contaminated Tap Water Kills 2 Neti Pot Users in Louisiana

Contaminated Tap Water Kills 2 Neti Pot Users in Louisiana

When two otherwise healthy people who both irrigated their sinuses with tap water died from a rare amoeba infection, officials in Louisiana issued a warning to other neti pot fans to use only distilled or filtered water.

Brain-eating Amoeba Common, Infection Rare

The amoeba Naegleria fowleri is common in lakes and ponds, especially in the warm waters of the southern United States. But, the micro-organism can only kill if it is introduced directly to the brain, usually through sensitive sinus tissues. Of the 32 U.S. cases of primary amebic meningoencephalitis (PAM) caused by Naegleria fowleri in the last 10 years, 30 were in recreational swimmers who were infected by getting water up their noses.

Because Naegleria fowleri isn’t dangerous when ingested, there are no drinking water standards for it and even testing for contamination isn’t very common. It’s assumed that normal chlorination or other municipal water treatment eliminates enough of the pathogen to make tap water safe for drinking and bathing, but nasal irrigation may be a totally different matter.

Safe, But Not Sterile Tap Water?

“We consider chlorination to be effective in killing [N. fowleri],”United States Centers for Disease Control and Prevention (CDC) epidemiologist Jonathan Yoder explains in a FoxNews story. “I can’t comment on any water system in Louisiana, but in general … you may start out with 1 million amoebas and your goal is to reduce it with chlorine, and you might get 99.9 percent out. But you’re probably never going to eliminate 100 percent. That goes for amoebas, parasites, bacteria, viruses. So while we say our drinking water is safe, it’s not sterile.”

“If you are irrigating, flushing or rinsing your sinuses, for example, by using a Neti pot, use distilled, sterile or previously boiled water to make up the irrigation solution,” Louisiana epidemiologist Dr. Raoult Ratard said in a statement to reporters. “Tap water is safe for drinking but not for irrigating your nose.”

Will The Risk from Brain-eating Amoebas Increase?

Risks of contracting PAM due to Naegleria fowleri is much higher for outdoor swimmers. Any warm body of freshwater could harbor the amoeba and children and teens jumping and diving into waterholes and lakes during the summer are most at risk. In fact, four people died last summer from the same infection.

Officials noted that neti pot use is on the rise now that several celebrities have endorsed them for warding off winter colds and sinus infections. At least one report indicates that the first victim was probably a new neti pot user and failed to put salt in his solution, something that may have killed the amoeba and prevented inflammation of the sinuses that gave it easy access to his brain.

And while more and more people are using neti pots, possibly improperly, surface water warming due to climate change may be expanding the geographic range of Naegleria fowleri.

Still, Naegleria fowleri infection is so rare and the amoeba is common in so many states it is unlikely that any one state water authority would increase testing and establish new safety standards for the amoeba. Drinking water standards is one of many areas where state agencies often welcome federal expertise in evaluating the risks of the many chemicals and microbes found in our water supplies. Unfortunately, a majority in the U.S. House of Representatives seems bent on blocking the Environmental Protection Agency or any other executive branch agency from implementing new regulations.

I'm glad to read this info, as I didn't know that there was this possible danger from Neti pots introducing this bacterium into brain tissue. Since I live in Texas on a ranch with well water, I will make sure my supply of water is boiled -- I do use salt in the Neti pot already. It is a great way to clear out one's sinuses (an old remedy, actually), if you live in an area of allergies, as we do here in cedar country. For those of you who haven't used it, I know it sounds bizarre, but it is a tried and true therapy, and works! Do it, first thing in the morning (you can in your shower), and you will be headachy, not get sick. I'm an advocate.

Sorry, I'm confused, I've never heard of Neti exactly does it work?

Thanks for the article.

Having lived in the country for a couple of years, I used to enjoy drinking the water but now I am in a city the water is barely drinkable still it must be pure think of all the people's kidneys it had gone through.

I never use tap water for any reason. Sad that people have died.

I have used a Neti Pot for years!!! Some days there is no other way to relieve the sinus congestion and pressure build-up. There is nothing more soothing than feeling the dehydration lift from your sinuses. My husband was a hold out, until he tried it for himself. Now he uses his Neti Pot regularly. We are on a well here in the very deep south. But, I still boil the water we use in our Neti Pots simply because I feel it is safer. Why take chances?

I still don't get the attraction to sticking a miniature teapot up your nose.

Just seems a little weird to me.
