True or False: Legionella is commonly found in samples from bottled water dispensers.

Legionella bacteria are primarily found in environmental water sources, such as natural bodies of water, hot tubs, and plumbing systems, rather than in bottled water. The bottling process typically involves filtration and disinfection, which significantly reduces the risk of Legionella being present. Thus, the assertion that Legionella is commonly found in samples from bottled water dispensers is incorrect, making the statement false.

While it is possible for bottled water to become contaminated under specific circumstances—such as during the production, bottling, or if the bottle is improperly handled after opening—the general expectation is that bottled water, especially those subjected to stringent quality controls, is safe and free from such contaminants.
