Resistance to triclabendazole in <i>Fasciola hepatica</i> on a commercial sheep farm in Taranaki, New Zealand

The finding of triclabendazole-resistant liver fluke in New Zealand should alert farmers and veterinarians to consider triclabendazole resistance as a potential cause of treatment failure, and adapt the farm liver fluke management and treatment regimens. In addition, resistant fluke could be widespread around New Zealand due to livestock being sold from this farm.
