Brain Eating Amoeba: A 71-year-old woman in Texas died after using unboiled tap water from an RV for nasal rinsing, leading to a rare but fatal infection caused by Naegleria fowleri — the so-called “brain-eating” amoeba. The case, confirmed by the CDC, has raised fresh concerns over improper water use in nasal irrigation and swimming. Infections are exceedingly rare but almost always deadly. Authorities stress the importance of safe water practices to avoid exposure, particularly in warmer months when the amoeba thrives.
