Trichinellosis in the European union: epidemiology, ecology and economic impact

Abstract

Trichinellosis, one of the most widespread helminthic zoonoses, is still endemic in most countries of the European Union. In the past few years, advanced biotechnology has been used to re-examine the taxonomy, epidemiology and life cycles of aetiological agents, providing additional information on the main factors contributing to the maintenance of these parasites in Nature. The old concept that pigs and rats are the main hosts of Trichinella spiralis, as still reported in many books, has been re-evaluated thoroughly. In this review, Edoardo Pozio summarizes the epidemiology and ecology of human and animal trichinellosis, quantifies the economic impact of this zoonosis and suggests methods of controlling this infection that would result in a great reduction in costs.
