Lake Mead contains a dangerous amoeba, according to results of a study published recently by the American Chemical Society. If taken in through the nasal cavity, the organism, Naegleria fowleri, can lead to brain inflammation and even death.

Between 2016 and 2024, researchers from multiple agencies collected and analyzed samples at sites including Lake Mead and four other national parks and recreation areas. Lake Mead, Yellowstone National Park, and Grand Teton National Park tested positive for the amoeba.

Hot springs feeding into Lake Mead from upstream may be the source of the organism, since it thrives in warm waters. Nevada reported one death from the inflammation at Ash Springs and one at Lake Mead during the period studied. Researchers are encouraging public officials to enhance monitoring, public awareness, and risk management in warm-water recreation areas.

Happy World Tuna Day!
To celebrate we thought it was time for you to Know Your Thunnus!
The Thunnus genus contains the group of fish known as true tunas. The fish of this genus are some of the most important to the fish trade, but also some of the most endangered. Thunnus species are powerful, streamlined and built for speed. A number are quite big, attain sizes much larger than a full-grown person and weighing as much as an average cow! Sadly, many of these amazing fish have been overfished and overexploited.
