Tres brotes de brucelosis investigados en un año de vigilancia de salud laboral en Ciudad Real / Three outbreaks of brucellosis in a one-year period investigated by the occupational health service in Ciudad Real (Spain)

Presentamos 3 brotes investigados por nuestro servicio de salud laboral en el periodo de 1 año. Dos de ellos, con 2 casos cada uno, en sendas queserías industriales, y el tercero en un laboratorio pecuario perteneciente a la administración autonómica, también con 2 casos. En las 2 queserías se encontraron numerosas oportunidades para que los trabajadores pudieran haberse infectado; se consideró como de mayor riesgo la zona de descarga de leche, y la no utilización de equipos de protección individual por los trabajadores, las deficiencias en los laboratorios y la falta de separación efectiva de las dependencias fueron también potenciale factores de riesgo. Respecto al laboratorio pecuario, se hallaron al menos 13 deficiencias importantes que permitían la fácil transmisión del agente infeccioso. En España, el riesgo de adquirir una infección por Brucella en laboratorios o industrias queseras es importante, y las condiciones y medidas para evitarlo que actualmente existen no son efectivas (AU)

We describe 3 outbreaks of brucellosis investigated by our Occupational Health Service in a 1–year period. Two of these outbreaks, with 2 cases each, occurred in 2 cheese factories and the third outbreak, also with 2 cases, occurred in a cattle laboratory belonging to the local government. In both cheese factories, numerous opportunities for the workers to become infected were found. The greatest risk was considered to be the area for unloading milk, while failure to use personal protection equipment by workers, deficiencies in the laboratories, and the lack of effective separation between areas were also potential risk factors. In the cattle laboratory, we found at least 13 major risk factors that could allow brucellosis transmission. In Spain, there is a substantial risk of Brucella infection in laboratories or dairy factories and current preventive measures are ineffective (AU)
