Brain-Eating Amoeba Scoffs At Chlorine In Water Pipes

An anonymous reader writes: The Naegleria fowleri amoeba typically feeds on bacteria in water and soil. Human digestive systems have no problem killing it, but inhaling water that carries the amoeba gives it the opportunity to work its way into the brain after it sneaks through the nasal mucus. It happens rarely, but 97% of people whose brains start swelling because of this amoeba end up dying. Like most microorganisms, N. fowleri can be neutralized with concentrated chlorine. However, the systems we use to deliver tap water aren't so clean. Researchers found that N. fowleri can easily survive for 24 hours when it's mixed with the types of biofilm that tend to reside in water pipes. Increasing chlorine levels isn't a good option, since its reaction with these biofilms can generate carcinogens.

    So basically, if you start showing the signs, you are probably gone.

      I guess the Capitalizing Every Word is their way of putting it in bold text, though not as bold as the end which becomes red and eventually all caps.

So it comes across as nothing but typical paranoia, e.g. maybe there's some rare chance that if your city doesn't chlorinate their water then you'll get some bacterial infection, requiring you to go to the doctor and get some antibiotics, and then you'll sue them for the $100 that cost you, and thus, you don't give a fuck and you can just use tap water if you want to.

      It just isn't a real warning if it doesn't mention the consequences. For example, the warning about using plain tap water is a real warning because it informs you about why you want to follow that advice. However, when it comes to what might actually kill you, they're completely silent about the consequences, likely because they don't want to say anything that might discourage people from using the product. As a result, I'm sure that damn near everyone who uses the product uses it with plain tap water, and that the only reason more people aren't dying is because it's simply an unlikely infection.
