Farmers are being advised to stay vigilant for any signs of coughing among cattle and to act quickly to prevent lungworm-related fatalities.

This year’s wet summer and mild temperatures have created ideal conditions for lungworm outbreaks, according to updated guidance from the AHDB.

The disease is estimated to cost farmers around £50–100 per animal in an outbreak.

The levy organisation explains that lungworm outbreaks can be severe and difficult to predict, with pasture contamination escalating quickly from low to high.

Finding a diagnosis to rule out other causes should be a priority, but the AHDB advises that early treatment particularly when a vet strongly suspects lungworm is ‘prudent’.

Calves in their first grazing season typically face the highest risk, but older animals may also become infected as immunity declines with a lack of exposure.

Farmers are advised to watch for signs like group coughing and difficult or rapid breathing, especially after activity.

Other symptoms to monitor include head extension, protruding tongue, and frothy saliva.

AHDB says: “As some of these clinical signs are similar to those of bluetongue, it is particularly important this year to seek advice from your vet to ensure the correct diagnosis.

"Speak to your vet about the best treatment options. In some cases, they may need to prescribe anti-inflammatories and/or antibiotics as affected animals are at risk of secondary bacterial infections.

"If your livestock are affected by lungworm this year, devising a control plan with your vet before the next grazing season will be invaluable."
