For years, the gleaming quartz countertops in modern kitchens have been a symbol of style and durability. But for the workers who cut, polish, and install them, those same surfaces can become a death sentence. In California, a growing number of Latino workers—many of them immigrants from México and Central America—are being diagnosed with silicosis, an irreversible lung disease caused by inhaling microscopic silica dust. Now, state regulators are moving toward a ban on the most dangerous materials.
The California Department of Public Health has documented 432 confirmed cases of silicosis among countertop fabrication workers between 2019 and November 13, 2025. At least 25 workers have died, and 48 have required lung transplants. The median age at diagnosis is just 46, and the median age at death is 48—a stark reminder that this is not an old-timer's disease. These are young men and women in the prime of their lives, often the primary breadwinners for their families.
Why engineered stone is so dangerous
Engineered stone, also known as quartz countertops, can contain more than 90% crystalline silica. When workers cut, grind, or polish this material, they release fine dust particles that, once inhaled, scar the lungs permanently. Unlike natural stone, which has lower silica content, engineered stone is particularly hazardous because of its high concentration and the way it fractures during fabrication.
Dr. Jane Fazio, a pulmonologist at UCLA who has treated many of these patients, told Latino World News, “We're seeing a public health emergency. These workers are coming in with advanced fibrosis, and many are in their 30s and 40s. It's devastating.” She added that the disease often progresses rapidly, and there is no cure—only supportive care or, for the lucky few, a lung transplant.
The problem is not confined to California. Similar outbreaks have been reported in Australia, Spain, and other countries where engineered stone is popular. But California's large Latino workforce in the fabrication industry makes it a particularly acute issue here. Many workers are undocumented and fear speaking up about unsafe conditions, which only compounds the risk.
Regulatory action and industry pushback
In response, the California Occupational Safety and Health Standards Board approved a petition on May 21, 2026, to evaluate a total ban on products containing more than 1% silica. The board has opened a public comment period that runs until September 30, 2026. If adopted, California would become the first state in the U.S. to impose such a strict ban, following the lead of Australia, which banned engineered stone in 2024.
Worker advocacy groups are pushing for immediate action. “Every day of delay means more workers exposed,” said María Hernández, a coordinator with the Labor Occupational Health Program at UC Berkeley. “We cannot wait for industry to voluntarily protect workers. They've had decades to do that.”
Industry representatives, however, argue that a ban would devastate small businesses and lead to job losses. They advocate for stricter enforcement of existing safety rules, such as wet-cutting methods and proper ventilation. But health experts counter that even with protective equipment, the risk remains high, especially in small shops where compliance is spotty.
Health impacts beyond the lungs
Silicosis is not the only concern. Chronic silica exposure has been linked to kidney disease, autoimmune disorders, and lung cancer. The state's health department has also reported cases of progressive massive fibrosis, a severe form of the disease that can be fatal. The toll on families is immense, both emotionally and financially. Many workers lack health insurance, and those who are undocumented may avoid seeking care until it's too late.
Community organizations are stepping in to fill the gaps. In Los Angeles and the Central Valley, mobile clinics are offering free lung screenings. Labor unions are holding safety workshops in Spanish, teaching workers how to use respirators correctly and what their rights are. And some families are turning to crowdfunding to cover medical costs, as they wait for workers' compensation claims to be processed.
What's next?
The public comment period is a critical window for workers, health experts, and industry to weigh in. If the ban is approved, it would likely take effect in 2027, giving businesses time to transition to safer materials like recycled glass or natural stone with lower silica content. But for those already sick, the damage is done.
As the debate continues, one thing is clear: the cost of a beautiful countertop should never be a worker's life. For the Latino community, this is not just a regulatory issue—it's a matter of survival. The state's decision will be watched closely by other states and countries facing the same dilemma.
