Brucellosis outbreak due to unpasteurized raw goat cheese in Andalucia (Spain), January - March 2002.

Eleven brucellosis cases were identified in three municipalities of Cordoba (Andalucia, Spain). A case-control study was conducted, selecting three cases per control. Persons having eaten unpasteurized raw goat cheese produced in a farmhouse located in the epidemic territory, were at higher risk for presenting brucellosis (OR=21.6, IC95%=1.6-639.8). Brucella melitensis serovar 3 was identified in clinical specimens and in goat tissue and milk samples from the herd's farmhouse. Preventive measures were implemented and the outbreak was stopped after the withdrawal of all suspicious cheeses from the market, additional sanitation of the farmhouse and health promotion activities.
