Trichinellosis is a rare parasitic zoonosis caused by Trichinella following ingestion of raw or undercooked meat containing Trichinella larvae. In the past five years, there has been a sharp decrease in human trichinellosis incidence rates in the European Union due to better practices in rearing domestic animals and control measures in slaughterhouses. In November 2014, a large outbreak of trichinellosis occurred in Belgium, related to the consumption of imported wild boar meat. After a swift local public health response, 16 cases were identified and diagnosed with trichinellosis. Of the 16 cases, six were female. The diagnosis was confirmed by serology or the presence of larvae in the patients' muscle biopsies by histology and/or PCR. The ensuing investigation traced the wild boar meat back to Spain. Several batches of imported wild boar meat were recalled but tested negative. The public health investigation allowed us to identify clustered undiagnosed cases. Early warning alerts and a coordinated response remain indispensable at a European level.
旋毛虫病是一种罕见的寄生虫人畜共患病，由摄入含有旋毛虫幼虫的生肉或未煮熟的肉引起。在过去五年中，由于家畜饲养方法的改进和屠宰场的控制措施，欧盟的人类旋毛虫病发病率急剧下降。2014年11月，比利时发生了一起与食用进口野猪肉有关的旋毛虫病大爆发。经过当地迅速的公共卫生应对，确定并诊断出16例旋毛虫病病例。在这16例病例中，6例为女性。通过血清学或患者肌肉活检中通过组织学和/或聚合酶链反应检测到幼虫来确诊。随后的调查将野猪肉追溯到了西班牙。几批进口野猪肉被召回，但检测结果为阴性。公共卫生调查使我们能够识别聚集性未确诊病例。在欧洲层面，早期预警警报和协调应对仍然不可或缺。
