The Parasight

Welcome to this month's edition of The Parasight. We’re taking parasite-threat updates to the next level with our collaboration with post-mortem vet Ben Strugnell BVM&S Cert PM MRCVS from Farm Post Mortems, who will share with us timely, on-the-ground footage.

Understanding what’s actually happening in flocks around the UK will give you more insights on what you should be looking out for with your own animals.

Weather and worms: farm risks explained - August 2025

Description: this month, Ben emphasises how weather patterns influence disease risk and provides an update on how current conditions are affecting parasite activity. He reports a high number of Haemonchus cases in certain areas across the country and outlines the key signs to look for during a post-mortem. He stresses that each farm is different, and that specific farm issues should be considered before selecting treatment options.

Ben also shares a few recent cases of Nematodirus in lambs and discusses how to respond, depending on post-mortem findings. Finally, he explains the link between grass length and worm risk in lambs and discusses options for managing that risk.
