Legionella bacteria were discovered in 12 out of 40 water samples taken at the Minneapolis Veterans Medical Center.
Despite these findings, no cases of Legionnaires’ disease have been reported in the area. Five out of the 12 samples that tested positive had Legionella pneumophila serogroup 1, which is the most common type of the Legionella bacteria to cause Legionnaires’ disease.
The Legionella findings occurred during the VA Hospital’s regular quarterly testing. According to Minneapolis officials, this is the first time that the Minneapolis Veterans Medical Center has tested positive for the pneumonia-causing bacteria. It is uncertain why this is the case; however, it is suspected that the use of a new testing service led to the bacteria’s discovery.
