NEW YORK, NY — A prominent national attorney specializing in Legionnaires’ disease litigation is commending General Motors for its decisive response after two employees at its Cole Engineering Center in Warren, Michigan, were diagnosed with the serious bacterial illness.
“General Motors acted quickly and responsibly,” said attorney Ronald J. Katter, who has represented victims in numerous high-profile Legionnaires’ cases. “Too often, companies delay action when faced with a public health risk. GM did the opposite — putting employee safety first by closing the building immediately and launching a thorough investigation.”
The two cases were identified earlier this month. GM responded by shutting down the building, initiating comprehensive water testing, and engaging third-party environmental experts to determine the source of the bacteria. Traces of Legionella — the bacteria that causes Legionnaires’ disease — were found inside the facility.
GM has said the building will remain closed until it is confirmed safe for employees to return. The company is now working closely with local health officials and outside specialists to develop a full remediation plan for all affected water systems.
The Centers for Disease Control and Prevention (CDC) estimates that about 10% of Legionnaires’ cases can be fatal, especially among individuals with compromised immune systems, chronic lung disease, or those who smoke. The disease is contracted by inhaling contaminated water vapor —commonly from sources like cooling towers, plumbing systems, or decorative fountains. It is not spread person-to-person and is treatable with antibiotics.
“This kind of transparency and action from a major employer sets a standard,” Katter added. “Other companies should take note of how GM handled this.”
The connection between the two employee cases and the building is still under investigation.
