Risk of lungworm high – Animal Health Ireland


Animal Health Ireland (AHI) has advised that the risk of lungworm in susceptible cattle is high following recent wet weather.

"As we enter the second half of the grazing season, and following the recent wet weather, the risk of lungworm (hoose) in susceptible cattle is high," according to AHI's latest bulletin. "Lungworm is caused by a roundworm, Dictyocaulus viviparus, which completes its lifecycle in the lungs of cattle. Clinical signs of infection include coughing and difficulty breathing, and death can occur with very little warning. Therefore, it is important that farmers be vigilant for signs of lungworm and take action without delay."

AHI advises that young cattle in their first grazing season, and older animals which have little immunity, are at greatest risk of infection. Animals grazing pasture that was grazed by infected cattle the previous year may become infected if the larval burden on the pasture is high, and animals can acquire a dangerous level of infection after even one day of grazing a contaminated pasture.

Close monitoring of animals for any sign of disease, with treatment of the entire group if coughing is observed, is recommended.
