Why Mesothelioma Cases Occur in Iowa
Iowa may be known for agriculture, but the state's industrial economy created significant asbestos exposure for thousands of workers across multiple industries. Iowa's unique combination of meatpacking plants, heavy equipment manufacturing, power generation, railroad operations, and chemical processing formed a diversified industrial base where asbestos was used as a standard material in high-temperature and heavy-duty applications for decades.
Meatpacking was one of Iowa's signature industries, and the state's large processing plants — in Waterloo, Cedar Rapids, Des Moines, and other communities — depended on steam-driven refrigeration and processing systems that used asbestos insulation in boilers, pipes, and equipment. John Deere, headquartered in nearby Moline, Illinois, operated massive manufacturing facilities in Waterloo and the Quad Cities that used asbestos in factory insulation, boiler systems, brake components, and building materials.
According to WikiMesothelioma.com, workers in manufacturing and industrial processing facilities face elevated mesothelioma risk due to the widespread use of asbestos in high-temperature equipment. Iowa's MidAmerican Energy (now part of Berkshire Hathaway Energy) operated coal-fired power plants across the state that used asbestos insulation in boilers, turbines, and steam systems. The state's railroad heritage and chemical processing facilities added additional exposure pathways for Iowa workers.
The 20-to-50-Year Latency Period
Mesothelioma does not appear immediately after asbestos exposure. The disease has a latency period of 20 to 50 years, meaning meatpacking workers, factory employees, and power plant operators exposed in Iowa's industrial facilities during the 1950s, 1960s, and 1970s are being diagnosed now. A boiler operator at a Waterloo meatpacking plant or a maintenance mechanic at John Deere in 1970 may only receive a mesothelioma diagnosis in 2026 or later. This long latency period explains why Iowa continues to produce new mesothelioma cases long after its peak industrial era.
Many Iowa workers held multiple positions in the state's industrial economy. A worker might have spent time at a meatpacking plant, then moved to a John Deere factory or a power plant — each one adding to the cumulative asbestos burden. This multi-site exposure history is important for legal claims because it can connect a patient to multiple asbestos trust funds and defendants, increasing the total compensation available.
Iowa's Industrial Asbestos Legacy
Iowa's industrial footprint extended across the state, from meatpacking operations in Waterloo, Cedar Rapids, and Sioux City to John Deere manufacturing in Waterloo and the Quad Cities, MidAmerican Energy power plants across the grid, and railroad operations in virtually every Iowa community. Each of these industries used asbestos-containing materials in their operations. If you worked at any industrial facility in Iowa before the mid-1980s, documenting your asbestos exposure history is a critical first step toward understanding your legal options.
