Water quality analysis - Legionella species testing (bathtub water, humidifiers, cooling towers, etc.)

Legionella: As short as 10 business days!

Legionella bacteria, when they infect humans, cause an infectious disease known as Legionnaires' disease. In nature, they are found in small amounts in soil and freshwater, but the likelihood of direct infection from these sources is almost nonexistent. However, conditions in places like baths and cooling towers are conducive to the proliferation of Legionella bacteria, so even a small aerosol (water spray) can contain a large number of Legionella bacteria, which can lead to infection when inhaled. Legionnaires' disease is an infection that occurs when aerosols contaminated with Legionella bacteria are inhaled into the body. Its symptoms can be broadly categorized into Legionella pneumonia and Pontiac fever, which is a febrile illness similar to influenza. Additionally, there have been reports of rare symptoms such as inflammation due to skin contact. Special caution is needed for the elderly, patients, and infants who have inherently low immunity. Legionnaires' disease is classified as a Category IV infectious disease under the Infectious Disease Control Law, and physicians who diagnose it are required to report it immediately to the health department.

basic information

【Facilities to Note】 Water supply equipment, hot water supply equipment, bathing facilities, cooling tower facilities, humidifiers, heat storage layers, water feature facilities, and other facilities where aerosols (water splashes) are likely to occur. 【Standard Values】 Bathtub water: Not detectable → Guidelines on water quality standards in public baths (Ministry of Health, Labour and Welfare) *In some prefectures, it may be indicated as not detected/100 mL. Cooling tower water: Less than 100 CFU/100 mL → Guidelines for preventing Legionnaires' disease *Although it is not a standard, if it exceeds 100 CFU/100 mL, immediate cleaning and disinfection measures must be taken, and after implementing these measures, it must be confirmed that the detected bacterial count is below the detection limit (less than 10 CFU/100 mL).
