Construction dust blamed for cluster of fungal infections in Williamson County

Dozens of residents in Williamson County have filed a lawsuit against multiple construction and development firms. The suit claims that dust generated by soil-disturbing activities near Spring Hill and Thompson’s Station caused histoplasmosis infections among local residents.

The complaint alleges that the companies failed to control dust during excavation and grading work. Plaintiffs state that fungal spores became airborne and were carried into nearby neighborhoods, where people inhaled them and became ill. The lawsuit names Jones Bros. Contractors and other defendants in the action.

Among the plaintiffs is Gwendolyn Brown, who has filed a wrongful death claim. She alleges her daughter, Alyssia Brown, died after contracting the fungal infection. The legal documents assert that the construction activities were the direct cause of the health issues.

Histoplasmosis is an infection caused by inhaling spores found in soil, often associated with bird or bat droppings. Disturbances such as demolition or clearing brush can release these spores into the air. In late 2025, the Tennessee Department of Health issued a warning about a rise in cases within Williamson and Maury counties.

Jones Bros. Contractors has filed a motion to dismiss two specific claims against it. The company argues that the complaint lacks sufficient specific allegations regarding gross negligence and strict liability. The alleged link between the construction sites and the illnesses has not yet been proven in court.

The case is currently active in Williamson County courts. Plaintiffs are seeking to hold the construction firms responsible for the spread of the spores. No trial date has been announced for the matter.
