Antiparastic Resistance

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.
