The first confirmed case of silicosis in Massachusetts’s stone countertop industry has health officials sounding the alarm on what experts are calling a “new and emerging epidemic.” A Hispanic man in his 40s, who worked for 14 years fabricating and installing stone countertops, has been diagnosed with the life-threatening lung disease.
“Silicosis is a devastating, life-altering disease – and one that is also absolutely preventable,” said Massachusetts Public Health Commissioner Robbie Goldstein, MD, PhD, in a recent statement.
California’s Growing Crisis
The Massachusetts case represents just the tip of what has become a full-blown health crisis in states with larger stone fabrication industries. California has confirmed 447 silicosis cases among countertop workers since 2019, with at least 25 deaths and 49 lung transplants. Earlier reports from November 2025 put the number at 435 cases, indicating the rapid growth of diagnosed cases even within weeks.
What’s particularly troubling? Many of the victims are relatively young workers in their 30s and 40s, primarily immigrants from Latin America, according to data from California’s occupational health monitoring.
By mid-November 2025, California had documented at least 25 silicosis deaths among countertop workers exposed to engineered stone materials. Most victims were in the prime of their working lives.
The Engineered Stone Connection
Public health experts point to a clear culprit: engineered stone, a material that has surged in popularity for kitchen and bathroom countertops. Unlike natural stone, these manufactured slabs contain dangerously high levels of crystalline silica.
“This is a new and emerging epidemic, and we must increase awareness of this disease process so we can avoid delays in diagnosis and treatment for our patients,” said Sundus Lateef, M.D., diagnostic radiology resident at the University of California in Los Angeles, who led a recent study on the condition.
Engineered stone contains over 90% silica, compared to less than 45% in natural granite, according to Massachusetts health officials. Some artificial stone products contain up to 95% crystalline silica, far higher than natural stones like granite or marble, reports indicate.
When workers cut, grind, polish, or shape these materials, they release dangerous silica dust that, when inhaled, causes irreversible lung scarring. Scientists have pinpointed specific fabrication processes that release the highest concentrations of this harmful dust.
A Preventable Tragedy
Health authorities in California have made silicosis a reportable condition, requiring healthcare providers to notify public health departments when they diagnose cases, according to a notice from San Luis Obispo County.
The California Department of Public Health has issued a new health advisory as cases continue to rise. Officials stress that proper dust control measures, including wet cutting techniques and adequate ventilation, could prevent most, if not all, cases.
For workers already diagnosed, the prognosis is often grim. Many require lung transplants or face premature death from a disease that develops after years of exposure but could have been entirely prevented with proper workplace safeguards.
As Massachusetts confronts its first confirmed case, the question looms: How many more workers might be suffering undiagnosed across the country, their lungs slowly scarring with each breath of silica-laden air in workshops prioritizing production over protection?
