Quartz Dust: A Hidden Danger for U.S. Workers

A growing epidemic of silicosis, an irreversible lung disease, is severely impacting workers in the U.S. countertop industry, particularly Hispanic men. California has documented over 550 cases, with more than 30 deaths and over 50 lung transplants recorded as of May 2026. The disease is caused by inhaling fine silica dust generated from cutting engineered quartz countertops.

Officials in California are considering a ban on cutting high-silica quartz material, following a petition by doctors who believe toxic ingredients in the material, beyond silica, may be contributing to the disease's severity. This health crisis is not isolated to California, with cases emerging in other states, though systematic tracking is inconsistent.

Experts suggest thousands of workers nationwide likely suffer from unrecognized lung damage, estimating potential cases to exceed 10,000. Many doctors are unfamiliar with silicosis, leading to misdiagnoses. Wade Hanicker, a Florida resident diagnosed with silicosis, shared his struggles with pain, weakness, and the inability to be active with his children.

Legal action is increasing, with a recent jury in Colorado awarding damages to a worker, Tyler Jordan, who developed silicosis and kidney failure. Manufacturers argue that proper safety protocols, such as dust control systems, can mitigate risks for both natural and engineered stone. However, occupational health experts counter that the material is too toxic to fabricate safely.

The U.S. Department of Labor's OSHA has implemented a targeted inspection program, finding that nearly 20% of sampled workplaces exceeded permissible silica exposure limits. Over 75 citations were issued for inadequate medical surveillance, highlighting a systemic issue in protecting worker health.
