PRRS alert from NPA highlights need for seasonal biosecurity audit

A warning that Reproductive and Respiratory Syndrome (PRRS) appears to be on the rise has been issued by NPA senior policy adviser, Dr Georgina Crayford.

Reminding farmers that we are now at the time of year when disease associated with PRRS increases, she has “strongly advised” producers to carry out a biosecurity audit with their vet to identify and tackle any weak points which might allow the virus to enter their farm.

“One of the likely reasons we see an increased risk at this time of year is that the virus survives better in cooler, damper and darker conditions,” she said. “It can also be more difficult to properly clean and disinfect pig buildings, vehicles and equipment during the winter.

“Similarly, fluctuations in temperature and problems with ventilation in the winter can predispose pigs to clinical outbreaks of respiratory and other disease.”

In addition to her NPA role, Dr Crayford (pictured above) also sits on the Pig Health and Welfare Council antimicrobial subgroup. She made her comments on the NPA website.
