Silicosis is a progressive, incurable lung disease caused by inhaling respirable crystalline silica dust. After declining across much of the 20th century thanks to industrial safety improvements, recent surveillance data shows the disease is returning. The resurgence is tied primarily to engineered stone countertop fabrication, with case numbers and severity patterns that alarm public health officials.
Since 2019, the California Department of Public Health has confirmed 432 cases of engineered stone-associated silicosis among countertop workers, including at least 25 deaths and 48 lung transplants as of November 2025. That figure is a sharp rise from the 259 confirmed cases recorded as recently as March 2025, a trajectory that shows just how quickly this epidemic is moving.
Confirmed cases are predominantly younger workers, many still under age 50. This age profile differs sharply from historical silicosis associated with long-term mining or construction exposure, where workers typically developed disease after decades on the job. Modern countertop fabricators are developing accelerated silicosis after just a few years of exposure.
California's multisource review data spanning 2019 to 2024 turned up 648 possible silicosis reports and 296 confirmed cases. Of those confirmed cases, 82% were tied to engineered stone exposure. The severity of what was found is reflected in the referral numbers, with more than one in four confirmed patients sent for lung transplant evaluation.
The severity and rapid progression distinguish this epidemic from traditional occupational silicosis. Workers present with progressive massive fibrosis and lung failure that would typically take decades to develop. The extremely high silica content of engineered stone, combined with intensive dust-generating tasks like cutting and grinding, creates exposure conditions far more hazardous than those found in other industries.
California, Michigan, Washington, and Wisconsin have all established state-based surveillance programs to track silicosis through hospital records, death certificates, and clinician reporting. California has taken an additional step by designating silicosis as a reportable disease, putting the onus on healthcare providers to flag diagnoses to public health authorities. It's a response to the disease's resurgence and the clear need for better data.
Even with improved surveillance, current case counts likely underestimate the true disease burden. Many workers are not screened systematically, and silicosis can take years to produce symptoms severe enough to prompt medical evaluation. By the time workers seek care, the disease is often advanced. Early-stage silicosis may only be detectable through chest imaging, but workers without symptoms rarely receive preventive screenings.
Historic CDC data from 2001 to 2010 showed silicosis deaths declining from 164 to 101 per year during that decade. However, the data still recorded dozens of deaths among people aged 15 to 44, demonstrating that young workers faced persistent risk even during the period of overall improvement. Recent trends suggest those modest gains are now reversing.
Research shows that many of the workers affected, particularly in engineered stone fabrication, are Spanish-speaking immigrants from Mexico and Central America. Active surveillance data in the U.S. has found that over 95% of affected workers were Spanish speakers, many of them employed in small fabrication shops with minimal safety infrastructure and limited access to occupational health resources.
Around 96,000 workers were employed in stone fabrication and related industries according to Bureau of Labor Statistics estimates from the late 2010s. Many face silica exposure without adequate protection, and workplace investigations have found that cutting, grinding, and polishing tasks routinely produce airborne silica levels above what regulations allow.
Workers facing language barriers, immigration concerns, and economic pressures often have little practical ability to report unsafe conditions or pursue medical care when symptoms develop. Job security fears and lack of insurance make the decision even harder. The result is that the disease goes underreported and, when workers do eventually seek treatment, the diagnosis often comes after significant damage has already been done.
Clusters of silicosis cases and fatalities tied to silica exposure have been documented in California, Colorado, Washington, and Texas. The geographic pattern reflects both where countertop fabrication is concentrated and where surveillance systems are developed enough to catch cases. States without active tracking programs are likely sitting on undetected cases they simply haven't found yet.
Early CDC surveillance data from 2017 to 2019 identified 18 cases across four states, including 2 fatalities. While these numbers appear small compared to California's current totals, they represented only states with established reporting systems. Expansion of surveillance to additional states will likely reveal the epidemic extends far beyond currently documented clusters.
Silicosis is incurable, and the damage it causes doesn't stop when exposure does. Silica particles that lodge in lung tissue set off scarring that cannot be undone, and treatment is limited to managing symptoms and heading off complications. Lung function, once lost, isn't coming back. The most severe cases end in lung transplantation or early death.
The progressive nature of silicosis means workers may feel fine during years of exposure, only to develop debilitating symptoms after leaving the industry. Some fabricators who worked with engineered stone for just three to five years now require oxygen therapy or await lung transplants. The delayed onset creates a false sense of safety that keeps workers in hazardous conditions until irreversible damage occurs.
If you worked fabricating, cutting, polishing, or installing engineered stone countertops and developed silicosis, progressive massive fibrosis, or severe restrictive lung disease, you may qualify for legal action against stone manufacturers and suppliers. For over 35 years, Atraxia Law has evaluated occupational exposure and product liability claims for workers harmed by toxic materials.
We will analyze your work history and medical records to determine if you are eligible for compensation from manufacturers who failed to warn about the extreme risks posed by engineered stone products. If we establish you have a viable claim, we will connect you with specialized attorneys experienced in silicosis litigation. Contact Atraxia Law today for a free case evaluation.
