Why Mesothelioma Cases Occur in McKinney
McKinney's industrial history is modest. The historic Collin Street Bakery and small-scale Collin County commercial operations were the main pre-1980 employers, without documented major asbestos exposure. McKinney's population has roughly tripled since 2000, driven by DFW suburban expansion rather than any local industrial buildout.
Residential asbestos exposure. McKinney has a meaningful stock of pre-1980 homes and commercial buildings in its historic downtown district, as well as older Collin County farmhouses and mid-century subdivisions. Homeowners or contractors who renovated these older structures may have disturbed asbestos in popcorn ceilings, vinyl floor tiles, pipe insulation, cement siding, or HVAC ductwork.
Commuter exposure. Many McKinney residents commuted to Dallas-area or Fort Worth-area industrial employers during their careers. TXU / Texas Utilities power stations, Mrs Baird's Bakery, Bell Helicopter, Lockheed Martin (GD Fort Worth), GM Arlington Assembly, and Love Field aviation maintenance all employed North Texas commuters with asbestos exposure histories.
Secondary (take-home) exposure. Spouses and adult children of DFW industrial workers who commuted from McKinney may have been exposed to asbestos fibers carried home on work clothes. This pattern is particularly common among women diagnosed with mesothelioma who laundered their husbands' or fathers' work clothes for decades.
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 workers exposed in McKinney-area facilities during the 1950s, 1960s, and 1970s are being diagnosed now. A tradesperson who worked around asbestos insulation in McKinney in 1970 may only receive a mesothelioma diagnosis in 2026 or later. This long latency period is why McKinney continues to produce new mesothelioma cases decades after asbestos use was curtailed.
McKinney's Asbestos Legacy by the Numbers
McKinney's limited industrial history means most mesothelioma cases trace to residential exposure, DFW-area occupational exposure, or secondary (take-home) exposure from DFW industrial workers. Texas allows 2 years from diagnosis to file a mesothelioma claim.
