ABSTRACT
Since East European countries joined the EU, the import of both dairy and beef cows from these countries increased considerably. Based on the identification and registration system it turned out that in the period from May until December 2007 about 200 cows per month were imported from Romania. These animals were either slaughtered immediately or in autumn. In autumn, cysts were noticed both in slaughtered cows during meat inspection and in deceased animals (originated from Romania) during postmortem investigation performed by the Animal Health Service. Because cysts were strongly reminiscent of Echinococcus granulosus hydatid cysts, samples were sent to the authorized laboratory (National Reference Laboratory of Parasitology), where the reintroduction of this potentially zoonotic parasitic infection has been confirmed. The risks of reintroduction of E. granulosus in the Netherlands are described.
