An outbreak of trichinellosis caused by ingestion of pork infected with Trichinella britovi occurred in the province of Granada in southern Spain in April–May 2000. Thirty-eight people were affected and 15 of them were hospitalized at the University Hospital of San Cecilio (Granada). The probable source of infection was sausage made from uninspected wild boar meat and inspected pork. Ninety-two percent of the patients had myalgias, 47.6% had diarrhea and/or vomited, 78.6% had periorbital edema, and 76.0% had fever. Twenty-two patients (15 hospitalized and 7 nonhospitalized) were serologically studied. Eosinophil levels were less than 5% of the total leukocyte count in 86.7% of the patients. Levels of creatinine phosphokinase (range = 200–2,213 U/L) and lactate dehydrogenase (range = 560–7,558 U/L) were elevated in 85.7% and 78.6% of the patients, respectively. Sixteen (72.7%) and 20 (90.9%) patients were positive for T. britovi by indirect immunofluorescence and Western blot, respectively.
