Keep water temperature either below or above the 20–55 °C (68–131 °F) range in which the Legionella bacterium thrives. [16] [26] Prevent stagnation, for example, by removing from a network of pipes any sections that have no outlet (dead ends). Where stagnation is unavoidable, as when a wing of a hotel is closed for the off-season ...
Legionella is a genus of gram-negative bacteria that can be seen using a silver stain or grown in a special media that contains cysteine, an amino acid.It is known to cause legionellosis [3] (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever.

A 100-mile-long bloom of red tide is floating off Southwest Florida, prompting warnings about respiratory irritation and potential fish kills on area beaches. Experts say weather could be helping ...
On Monday, as much of the country stewed in bubbling heat, a boiling milestone was hit — a buoy in Florida registered a jaw-dropping 101.1 degrees Fahrenheit water temperature.
Temperature affects the survival of Legionella as follows: [93] 70 to 80 °C (158 to 176 °F): Disinfection range; At 66 °C (151 °F): Legionellae die within 2 minutes; At 60 °C (140 °F): They die within 32 minutes; At 55 °C (131 °F): They die within 5 to 6 hours; Above 50 °C (122 °F): They can survive but do not multiply
A water temperature buoy located inside the Everglades National Park in the waters of Manatee Bay hit a high of 101.19 degrees Fahrenheit (38.44 Celsius) late Monday afternoon, U.S. government ...
Record global ocean heating has invaded Florida with a vengeance. Water temperatures in the mid-90s (mid-30s Celsius) are threatening delicate coral reefs, depriving swimmers of cooling dips and ...
Two conflicting safety issues affect water heater temperature—the risk of scalding from excessively hot water greater than 55 °C (131 °F), and the risk of incubating bacteria colonies, particularly Legionella, in water that is not hot enough to kill them. Both risks are potentially life-threatening and are balanced by setting the water ...
