A case of a highly pathogenic bird flu has been confirmed in Enniskillen on Tuesday.
The H5N1 avian influenza virus has been detected in a small flock of mixed species birds in a backyard in the Co Fermanagh town.
The Department for Agriculture, Environment and Rural Affairs confirmed the discovery of the case and said a 3km protection zone and 10km surveillance zone had been put in place around the infected premises.
The case comes in addition to a number of other confirmed cases throughout Northern Ireland, including two cases in Co Tyrone.
“Unfortunately we have confirmed another incursion of HPAI H5N1 in a small, mixed species, backyard flock in Enniskillen,” NI Chief Veterinary Officer Robert Huey said.
“Although this is extremely disappointing it is not unexpected. It is a timely reminder that bird flu is still present in the environment and we must continue to be vigilant.
“We cannot afford to get complacent. This strain will use any gaps in biosecurity to gain access to a flock.”
Agriculture Minister Edwin Poots said birdkeepers should be vigilant to the threat of the disease.
“I am calling on all bird keepers, particularly those with small backyard flocks, to review their biosecurity practices,” Poots said.
“Excellent biosecurity remains the most effective defence for reducing transmission of avian influenza to poultry or captive birds and it is vitally important that all bird keepers adhere to the strict enhanced biosecurity measures of the Avian Influenza Prevention Zone (AIPZ) which remains in place in Northern Ireland.”
