California's Public Health Emergency

The California Department of Public Health (CDPH) has recently issued a crucial health advisory in response to the alarming increase in cases of silicosis among workers in the artificial stone countertop fabrication industry. Silicosis, a serious and incurable lung disease resulting from inhalation of crystalline silica dust, has seen a drastic rise in confirmed cases, making it a matter of urgent public health concern.

Understanding Silicosis

Silicosis is caused by the inhalation of tiny crystalline silica particles, commonly found in artificial stone, which is often marketed as quartz countertops. This material is composed of a significant amount of crystalline silica that is released into the air during the processes of cutting, grinding, and polishing, exposing workers in the industry to harmful dust.

As of December 4, 2025, the number of reported silicosis cases among these workers escalated from a mere 13 cases in 2019 to a staggering 447, featuring 25 fatalities and 49 lung transplants. Alarmingly, the median age of diagnosis is just 46 years old, with victims succumbing at a median age of 48, indicating a widespread impact on younger demographics.

New Reporting Standards and the Need for Surveillance

In June 2025, significant changes were made to reporting requirements, mandating healthcare providers to inform local health departments of any suspected or confirmed silicosis cases within seven days. This increased level of surveillance is intended to enhance tracking of the disease, improve access to care for affected individuals, and inform statewide interventions aimed at curbing the spread of this life-threatening condition. However, underreporting persists, leading to the grim reality that actual cases could be far greater than those documented.

Regional Analysis of the Epidemic

The outbreak of silicosis is particularly pronounced in specific California counties:

• - Los Angeles: 236 cases
• - Orange: 90 cases
• - San Diego: 36 cases
• - Contra Costa: 19 cases
• - Alameda: 15 cases
• - San Bernardino: 13 cases
• - Riverside: 10 cases

Legislative Actions and Compliance

In light of this public health crisis, California's strict Cal/OSHA regulations are under scrutiny, particularly those that pertain to the fabrication of crystalline silica artificial stone countertops. These regulations include guidelines on utilizing wet cutting techniques, ensuring proper dust cleanup, and mandating the usage of respirators. However, studies have indicated that there is no completely safe method to fabricate these materials.

The urgency is growing for lawmakers and public health officials, who are advocating for a prohibition on the use of crystalline silica artificial stone in fabrication. Senate Bill 20, set to come into effect in January 2026, will require that all cases of silicosis related to artificial stone be reported to Cal/OSHA for further investigation, enhancing the management of these cases through local health officers.

Available Resources and Support for Affected Workers

The CDPH's Occupational Health Branch is providing educational materials and technical assistance aimed at employers, workers, and healthcare professionals. There are also additional resources available from organizations such as the CDC NIOSH and the American Thoracic Society to further guide the community in navigating this crisis.

Call to Action

This updated health advisory and the activation of an enhanced surveillance dashboard reflect the pressing urgency for immediate action to protect workers from the dangers associated with crystalline silica artificial stone slabs. Manufacturers and suppliers are called upon to implement preventive measures to avert more tragedies.
