“Choice of treatment is extremely important, and SCOPS and COWS are committed to providing clear advice on the options available. As part of this commitment, we are aware there has been misunderstanding with respect to two veterinary medicines that are not currently authorised in the UK, but which have been imported from the Republic of Ireland under a Special Import Certificate from the Veterinary Medicines Directorate, for use on some UK farms. These veterinary medicines both contain the active substance rafoxanide, and it is apparent there is significant confusion around rafoxanide, especially with respect to using it as an alternative to closantel on farms where triclabendazole resistance is proven. SCOPS and COWS have therefore updated their respective websites to provide clear information to sheep and cattle farmers.”
Speaking on behalf of COWS, Professor Diana Williams adds:
“This is extremely important because it means there is no evidence to suggest using closantel and rafoxanide interchangeably/on a rotational basis will successfully reduce the selection pressure for resistance to closantel. Indeed, there is a serious risk that such use of rafoxanide will hasten the development of resistance to closantel. It would be fantastic for both sheep and cattle farmers if rafoxanide was a new active against fluke, and we’d be shouting about it loud and clear if it was. Unfortunately that is not the case and we do not want people working in the livestock industry to mistakenly think the two products containing rafoxanide are ‘silver bullets’, when in fact their overuse could do more harm than good.”
SCOPS and COWS urge farmers, their vets and other advisors to heed this new advice and take on board the latest information. Clear information is available on both the website about the importance of diagnostic testing before treatment, different flukicide products available, the age of fluke those products target, and the appropriate time of year to use them.
