As part of our Hill Sheep Health North project, 10 farms in Cumbria and the Yorkshire Dales began Elisa blood testing this year’s lambs in October.  Only 3 of the farms have had one single positive result, indicating that, so far, only a small proportion of these flocks have fluke.  Any fluke treatments before the end of October may have been have been a waste of money but the farmers are continuing to test their lambs for evidence of greater exposure.  It demonstrates the importance of working with your vet to understand the fluke situation each season, monitoring your flock using sentinel animals, targeting your treatments to save costs and reducing the risk of resistance.
