Bulgarian veterinary authorities will cull 55,000 hens in the northern town of Slavyianovo after a bird flu outbreak was confirmed at a industrial farm there, the fourth since February 3, the food safety agency said late on Monday.
The agency said the four farms have been hit by highly pathogenic avian influenza type A, but did not disclose the strain of the disease.
The predominant strain in Europe at present is H5N8.
Some 160,000 ducks and 99,000 have been culled at three farms in Slavyianovo, some 190 km northeast of Sofia, this month as authorities try to contain the spread of the disease.

Russian authorities have reported 7 poultry farm workers aged 29 to 60 years infected with the A(H5N8) strain of avian influenza, also known as bird flu. This is the first reported detection of this strain of avian influenza in humans. The human infections occurred on a poultry farm in Astrakhan, Russian Federation, and were reported to WHO by Russian health officials via channels of the International Health Regulations (2005).
Concerns were raised when 101 000 out of 900 000 egg-laying hens on the farm died in early December 2020. An investigation by Russian veterinary public-health authorities detected avian influenza A(H5N8), which was then confirmed by the World Organisation for Animal Health (OIE) Reference Laboratory and the Federal Centre for Animal Health in the city of Vladimir, Russian Federation.
Follow-up tests on the 7 workers from the poultry farm suggested recent infection with the virus, though they showed no symptoms. There was no clinical evidence of onward transmission to families or close associates of the workers. Further information on serology among contacts of the positive cases is required to fully assess the risk.
Dr Richard Pebody, who leads the High Threat Pathogen Team at WHO/Europe, was quick to reassure: “The people who were reported to be infected did not develop symptoms and they were all exposed to an infected poultry flock in the course of their work. The infection does not appear to have come from other human beings – which is good news.”
Dr Pebody added, “The poultry flock has been culled and no further infections in humans have been found. It is also encouraging that this incident shows the system that alerts local and international authorities is working. However, this underlines the ongoing importance of global surveillance in the face of constantly evolving influenza viruses. Changes to the influenza virus must be closely monitored in animals and humans alike; this is a good example of the One Health approach, recognizing that human and animal health are intertwined and depend on each other.”
Based on available information, the risk of human-to-human transmission remains low and WHO recommendations have not changed as a result of the incident. When avian influenza is circulating in an area, farms and contact with live animals, for example in markets, should be avoided. Precautions must be taken by those working with poultry.
WHO is now following up with public health authorities in the Russian Federation and other relevant organizations. Although this strain of influenza has not previously been known to affect humans, it has been detected in farmed and wild birds in countries across the European Region, including Bulgaria, Czechia, Germany, Hungary, Kazakhstan, the Netherlands, Poland, Romania and now the Russian Federation.

Thirteen thousand birds are to be culled at farm in Cheshire after avian flu was confirmed there.
The H5N8 strain of bird flu was detected at a broiler breeders premises in Frodsham, the Department for Environment, Food and Rural Affairs (Defra) said.
It said it was not related to the H5N2 strain found at a small farm near Deal in Kent earlier.
Public Health England (PHE) said the risk to public health was “very low”.
All 13,000 birds at the farm, which produces hatching eggs, will be culled, said Defra.
Further testing is under way to determine if it is a highly pathogenic strain and whether it is related to the virus currently circulating in Europe.
The UK’s chief veterinary officer Christine Middlemiss, said: “Immediate steps have been taken to limit the risk of the disease spreading.
“This includes 3km and 10km temporary control zones around the infected site.
“We are urgently looking for any evidence of disease spread associated with this farm to control and eliminate it.”
Dr Gavin Dabrera from PHE said: “There have never been any confirmed cases of H5N8 in humans and the risk to public health is considered very low.”
A Food Standards Agency spokesperson said: “On the basis of the current scientific evidence, avian influenzas pose a very low food safety risk for UK consumers.
“Properly cooked poultry and poultry products, including eggs, remain safe to eat.”
