Illinois Mesothelioma Statistics 2026: Cook County Verdicts, Exposure Industries, and Legal Deadlines

Illinois is one of the most heavily impacted states for asbestos-related disease. The combination of steel production, heavy manufacturing, railroad infrastructure, and vermiculite processing created exposure pathways that reached tens of thousands of workers across the Chicago metropolitan area and downstate industrial corridors.

The toll, measured in cases, deaths, and families still receiving diagnoses decades after exposure, places Illinois consistently among the top states for mesothelioma burden.

State Context

Where Exposure Happened

Illinois’s asbestos burden traces to three primary industrial sectors that defined the state’s economy through the 20th century.

Steel and Metal Production

Chicago’s Southeast Side was one of the largest steelmaking corridors in the world. U.S. Steel South Works operated from 1882 to 1992 on the Calumet River, employing hundreds of thousands of workers over its 110-year history. Wisconsin Steel, Republic Steel (later LTV Steel), and dozens of smaller foundries and fabrication shops surrounded it. The pattern mirrors what happened in Ohio’s Rust Belt and Indiana’s Gary steel corridor, where the same companies used the same asbestos products.

Inside these mills, asbestos insulated blast furnaces, ladles, pipes, and electrical systems. Workers who handled, maintained, or worked near insulated equipment inhaled fibers daily. The exposure was most acute for insulators, pipefitters, millwrights, and maintenance crews, but production workers in adjacent areas were also exposed.

Vermiculite Processing

Illinois was one of the largest processors of contaminated vermiculite from the Libby, Montana mine. Confirmed processing sites operated in Girard, Peoria, Quincy, Buda, and Calumet City, as well as in the Chicago area.

Vermiculite from the Libby mine was contaminated with tremolite asbestos. Workers who processed it into attic insulation, potting soil additives, and construction materials breathed fiber-laden dust throughout their shifts. Community exposure extended to residents living near processing facilities.

Railroad and Manufacturing

Chicago was the nation’s railroad hub, and railcar maintenance, locomotive repair, and freight handling all involved asbestos-containing components. The B&O Railroad, Chicago and Northwestern Railway, and dozens of other lines operated repair facilities across the region.

Manufacturing plants producing boilers, gaskets, electrical components, and automotive parts also used asbestos extensively. These worksites, combined with the construction trades, created a broad, overlapping web of exposure that touched workers across nearly every industrial sector.

County-Level Data

Cook County alone accounts for a disproportionate share of the state’s cases, reflecting the concentration of heavy industry in the Chicago metropolitan area. Lake and Rock Island counties have also been identified among the top 20 counties nationally for mesothelioma rates.

Who Is Most at Risk

The occupations with the highest exposure in Illinois mirror the state’s industrial profile:

• Steelworkers at South Works, Wisconsin Steel, Republic Steel, and smaller mills
• Pipefitters and insulators across industrial and commercial construction
• Railroad workers in maintenance yards and locomotive shops
• Boilermakers at power plants and industrial facilities
• Vermiculite processors at Libby-connected facilities
• Construction tradespeople working in pre-1980 buildings
• Factory workers at automotive, chemical, and electrical manufacturing plants

Secondary exposure also affects families. Workers carried asbestos fibers home on clothing, exposing spouses and children to the same material that caused their own disease. Under the precedent established in Quisenberry v. Huntington Ingalls (Virginia Supreme Court, 2018, Record No. 171494), courts have recognized that employers owe a duty of care to workers’ family members in take-home exposure situations. Several recent Cook County verdicts have specifically addressed take-home exposure cases, including a $30 million award for secondhand asbestos exposure from a factory worker’s clothing.

Legal Landscape

Cook County has emerged as one of the most active jurisdictions for mesothelioma litigation in the country. Recent verdicts include:

• $40.75 million against John Crane Inc. (2023): Estate of Bruce Torgerson, represented by daughter Annette Beneville. Cook County jury awarded $40.75M including $10M in family damages for exposure to asbestos-containing gaskets and packing at industrial plants and refineries. Verdict standing.
• $45 million against Johnson and Johnson and Kenvue (April 2024): Estate of Theresa Garcia. Liability split 70% Kenvue / 30% J&J. Illinois Appellate Court upheld the verdict on appeal in 2024. Verdict standing.
• $30 million against Bridgestone Firestone (December 22, 2023): Dorothy J. Jackson, administrator of the Estate of Thomas J. Jackson, case no. 19 L 009793. Thomas Jackson developed peritoneal mesothelioma from asbestos fibers on his father’s clothing from the Bridgestone Firestone plant in Decatur, Illinois. Damages included $5.25M economic, $11.14M wrongful death, and $13.6M survivor damages. Verdict standing.

Illinois law allows claims against both solvent companies and bankrupt defendants through asbestos trust funds. An experienced mesothelioma attorney can identify all applicable trusts based on a worker’s employment history and the products used at their specific jobsites. For families navigating these options, the treatment landscape is also evolving, with five-year immunotherapy survival data now available from the CheckMate-743 trial.
