Silicosis Prevalence and Occupational Risk Factors in the Stone Industry: Research Review
Systematic reviews and meta-analyses of silicosis prevalence in the stone fabrication industry provide the epidemiological foundation for current regulation. This article summarises key findings from peer-reviewed research published between 2018 and 2026, with a focus on what the data means for buyers, specifiers, and fabricators.
The data that changed everything: Australian screening programs reported silicosis prevalence rates of 12-25% among engineered stone workers with 5-10 years of exposure — rates comparable to historical mining populations with decades of exposure. The combination of high prevalence and rapid disease progression (accelerated silicosis appearing in workers under 35) is what distinguishes engineered stone from traditional occupational silica exposure.
Key Findings
- Prevalence: Screening programs in Australia, Israel, and the US report silicosis in 10-30% of screened engineered stone workers
- Latency: Accelerated silicosis diagnosed after as little as 4-7 years of exposure — compared to 15-30 years for chronic silicosis in mining
- Risk factors: Dry-cutting (highest risk), inadequate ventilation, inconsistent PPE use, and lack of medical surveillance
- Disease progression: Unlike chronic silicosis, accelerated silicosis can progress even after exposure ceases — making prevention the only effective intervention
- Underdiagnosis: Most studies note that passive surveillance (relying on workers to present symptoms) misses the majority of cases — active screening programs are essential
