Iowans Affected by Legionella Outbreak Consider Legal Action in 2025
A preventable tragedy unfolds in Marshalltown, Iowa, as a Legionella outbreak leaves residents seeking justice.
The year 2025 has brought unforeseen challenges to the residents of Marshalltown, Iowa. A severe outbreak of Legionnaires’ disease has swept through the community, leaving a trail of illness, death, and uncertainty. As of late September 2025, the Iowa Department of Health and Human Services (HHS) has reported 73 confirmed cases and two deaths linked to the outbreak in Marshall County. The outbreak has prompted many Iowans affected by the Legionella outbreak to consider legal action in 2025 against those responsible for the outbreak.
What is Legionnaires’ Disease?
Legionnaires’ disease is a severe form of pneumonia caused by Legionella bacteria. People contract the disease by inhaling microscopic water droplets contaminated with the bacteria. These droplets can come from various sources, including:
- Cooling towers (air conditioning systems for large buildings)
- Hot tubs and spas
- Decorative fountains
- Large plumbing systems
The Legionella bacteria thrive in warm water environments (77 to 113°F), making improperly maintained water systems a breeding ground for the disease. Legionnaires’ disease is not contagious and cannot be spread from person to person. While most healthy individuals exposed to the bacteria do not get sick, certain populations are at higher risk, including:
- Adults aged 50 and older
- Smokers
- People with weakened immune systems
- Individuals with chronic lung conditions
Symptoms of Legionnaires’ disease are similar to other forms of pneumonia and may include:
- Cough
- Fever (up to 105°F)
- Headaches
- Muscle aches
- Shortness of breath
- Chest pain
- Gastrointestinal symptoms (nausea, diarrhea)
The Marshalltown Outbreak: A Timeline of Events
The Iowa Department of Health and Human Services (HHS) announced an investigation into a cluster of Legionnaires’ disease cases in north central Marshalltown on September 4, 2025. Since the beginning of the investigation, 73 individuals have been diagnosed with Legionnaires’ disease and two older adults with underlying health conditions have died.
Identifying the Source: Cooling Towers Under Scrutiny
Health officials have been actively collecting water samples from cooling towers at 12 businesses in north Marshalltown. The samples are sent off to the state hygienic lab in Iowa City where they’re run through a filter to identify Legionella bacteria. While laboratory testing has not yet confirmed a direct source, all available evidence indicates cooling towers are the most likely source of the Marshalltown outbreak.
Legal Recourse for Victims of Legionnaires’ Disease
When individuals contract Legionnaires’ disease due to negligence, they may have grounds for legal action. Potential legal claims often hinge on:
- Duty of care: Property owners and operators have a responsibility to maintain safe water systems.
- Negligence: Failure to properly test, disinfect, or treat contaminated systems constitutes negligence.
- Causation: Linking exposure at a specific site to the illness is crucial. Confirmed outbreaks with identified sources strengthen this link.
- Damages: Victims may seek compensation for medical expenses, lost wages, long-term health problems, and pain and suffering. In the event of a fatality, families may pursue wrongful death claims.
What to Do If You Suspect Exposure
If you or a loved one suspects exposure to Legionella bacteria, take the following steps:
- Seek immediate medical care: Request specific testing for Legionella. Early diagnosis and treatment with antibiotics are crucial.
- Document your history: Keep a record of your travel and lodging history, especially recent stays in hotels, apartments, or healthcare facilities.
- Save all records: Preserve all medical records and expense documentation.
- Consult with an attorney: Seek guidance from an attorney experienced in Legionnaires’ disease cases to understand your legal rights and options.
Preventing Future Outbreaks: A Call for Vigilance
The Legionnaires’ outbreak in Marshalltown serves as a stark reminder of the importance of proper water system maintenance and Legionella prevention. Building owners and operators must take proactive steps to minimize the risk of future outbreaks, including:
- Implementing Water Management Programs: Establish, maintain, and regularly review comprehensive water management programs.
- Regular Testing and Disinfection: Conduct routine testing for Legionella bacteria and implement appropriate disinfection protocols.
- Proper Maintenance of Cooling Towers: Drain cooling towers when not in use and ensure they are mechanically cleaned and maintained according to the manufacturer’s recommendations.
- Adhering to Public Health Guidelines: Stay informed about and comply with recommendations from public health agencies like the Iowa HHS and the CDC.
Conclusion: Seeking Accountability and Preventing Future Harm
The Legionnaires’ disease outbreak in Marshalltown, Iowa, has had a devastating impact on the community.
