How to Avoid Legionella

Legionella is a type of bacteria that can cause a serious lung infection called Legionnaires' disease. The bacteria is commonly found in water sources, such as hot tubs, cooling towers, and large plumbing systems. Here are some steps you can take to avoid Legionella:

1. Keep hot water hot and cold water cold: Legionella grows best in warm water temperatures between 77-108°F (25-42°C). So, to prevent the bacteria from growing, make sure that hot water is heated to at least 140°F (60°C) and that cold water is kept below 68°F (20°C).

2. Clean and disinfect water systems: Regularly clean and disinfect all water systems in your home or workplace, such as hot tubs, showers, and faucets. This helps to eliminate any Legionella bacteria that may be present.

3. Maintain water systems: Properly maintain all water systems in your home or workplace, such as cooling towers and hot water tanks, to prevent the buildup of Legionella bacteria.

4. Use caution with hot tubs and spas: If you use a hot tub or spa, make sure to maintain it properly and follow the manufacturer's instructions for cleaning and disinfecting. Also, avoid using a hot tub or spa if you have any open wounds or cuts, as this can increase the risk of infection.

5. Regularly clean and disinfect humidifiers: If you use a humidifier, make sure to clean and disinfect it regularly to prevent the growth of Legionella bacteria.

6. Be aware of high-risk locations: Be cautious when visiting high-risk locations such as hospitals, nursing homes, and hotels, as these places often have large plumbing systems that can harbor Legionella bacteria.

By following these steps, you can help prevent the growth and spread of Legionella bacteria, and reduce the risk of Legionnaires' disease.
