Engineered stone crisis: Quartz countertops linked to deadly silicosis in the U.S.
Two occupational health experts warn that engineered stone countertops (often marketed as quartz) expose workers to crystalline silica, fueling a growing silicosis crisis in the U.S. California has diagnosed more than 550 cases, with about 100 lung transplants and at least 30 deaths since 2019. Lawsuits against manufacturers and retailers are rising while enforcement remains under-resourced; global outbreaks have led to regulatory changes elsewhere, and calls mount for stricter rules or a US ban on crystalline silica–containing engineered stone.
