Tests on a batch of piglets submitted by a veterinary practice to the Agri-Food & Biosciences Institute last week have tested positive for the virus.

A DARD spokesperson said: “Influenza viruses, including Influenza A, are present in all pig producing countries, including here and Great Britain and are considered endemic in the pig population.

“Given that this virus is currently circulating in humans this finding is not unexpected.”

As part of the Department’s contingency planning, a voluntary Code of Practice for pig keepers has been agreed with the industry.

It provides guidance to pig keepers on the actions they should take to reduce the risk of introduction of influenza viruses to pig herds and reduce the risk of onward spread if introduction does occur.

The Department is providing advice to the affected farm and will continue to monitor developments and provide advice to the industry as required.

The Food Standards Agency has advised that the virus does not pose a food safety risk to consumers.
