Silicosis cases rise among engineered stone workers

A surge in silicosis cases among workers fabricating engineered stone countertops is triggering massive legal liabilities and public health concerns. Researchers in California have confirmed 592 cases of the incurable lung disease, including 31 deaths and 65 lung transplants. The affected group is notably young, with a median diagnosis age of 46, and is predominantly Latino.

Silicosis is caused by inhaling fine silica dust, which is highly concentrated in quartz countertops made from crushed natural quartz and polyester resins. Unlike traditional silicosis seen in miners, these cases are characterized by rapid disease progression and shorter exposure durations.

The stone industry is facing significant legal consequences, with recent jury verdicts ranging from $7.1 million to $52.4 million. In one case, manufacturer Daltile was found liable for negligence and design defects. While litigators argue manufacturers failed to provide adequate warnings, industry representatives, such as Cambria, have pointed to insufficient enforcement of existing OSHA regulations rather than product defects.
