What is antiparasitic resistance?

Antiparasitic resistance may be defined as the ability of a parasite e.g. gut worms/liver fluke to survive a dose of an antiparasitic drug that would normally be expected to kill them. If a large proportion of the parasites on a given farm are resistant to a given antiparasitic drug, treatment of the animals with that drug will no longer be effective.

If we do not act now, antiparasitic resistance will threaten animal health and welfare as well as the future sustainability and profitability of Irish cattle and sheep farming. It is by ensuring the responsible and prudent use of these invaluable medicines in animals that we will be able to safeguard their efficacy for future use.

Antiparasitic Resistance Stakeholder Committee

In June 2020 DAFM established an Antiparasitic Resistance Stakeholder Group, chaired by the Chief Veterinary Officer, to address concerns related to the changed route of supply and to ensure a holistic approach is adapted in fostering the informed and prudent use of antiparasitics. Representative bodies from all stakeholder areas are involved with the Group. Three meetings have been held to date. This group will examine all the issues with two principal objectives:

Protecting the efficacy of antiparasitics which are critical to the Irish pasture-based production model.
Establishing a regulatory system that is pragmatic, retains a substantive role for existing stakeholders and delivers value for money for farmers.
