In this note we present the increased prevalence of silicosis found in a marble factory after exposure to a new presentation of silica. A prospective, observational study was conducted on 11 workers who were exposed to different presentations of quartz surfaces since 1995. The jobs were divided into two groups: 4 subjects worked in the cutting workshop; the rest of the workers worked in assembly. Up to that date they had not used any specific respiratory protection apparatus. Six cases of silicosis have been diagnosed, which assumes a disease prevalence in this environment of 54.5%. Of the 6 affected, 5 (83.3% are assemblers. We highlight the high risk of developing silicosis in the handling of different products which make up the range of quartz surfaces.
