FDA inspected American Cruise Line's American Star and American Heritage vessels from in April 2022, through June 2022, and from June 2022, through August 2022. The investigation and inspections were initiated by FDA after three passengers who traveled in April 2021, September 2021, and September-October 2021 aboard these vessels were diagnosed with Legionnaires’ disease. FDA investigators collected biofilm swabs and potable water samples from these vessels and identified Legionella pneumophilia serogroup 1 and Legionella spp. in the potable water system of the vessels thus determine that the water is adulterated as defined by regulation..
FDA had issues with the response by the company in terms of response to the issue. There were issues with the test methodology the company was using..The company did "not monitor potable water parameters, such as free or total chlorine residual, temperature, and pH on the vessel when docked and not in operation or while in operation."
