The
Ministry of Agriculture
has confirmed the detection of the
Highly Pathogenic Avian Influenza Virus
(
HPAI
)
H5N1
in several wild birds that have been found dead in the Segre river as it passes through
Soses
(
Lleida
), the first in the country so far of year.
It is the same bird flu virus that has caused massive bird deaths in
Israel
in recent weeks , in what local authorities consider the worst blow to wildlife in the country's history.
As Ministry sources have informed Efe, it was Rural Agents of the Generalitat who found four swans (Cygnus olor) and a stork (Ciconia ciconia) dead in the river due to this viral disease, within the framework of the observation work of the National Program of Avian Influenza Surveillance in Spain.
Once the swab samples were obtained from the deceased birds, they were sent for analysis to the
IRTA-CReSA
laboratory , where positive results were obtained by PCR for the H5 subtype of the virus.
The results were confirmed in the
Central Veterinary Laboratory
(LCV) of
Algete
(Madrid) and it was determined that it is a strain of
IAAP H5N1
.
Surveillance around the outbreak
Upon confirmation, the Rural Agents of the Generalitat of Catalonia and the Environment of the Government of Aragon intensified "immediately" the passive surveillance of wild birds in the surrounding area of 10 kilometers around the outbreak, prioritizing the first 3 kilometers.
The Ministry assures that there are no commercial poultry farms in these first kilometers and that the controls of the farms located within the 10-kilometer radius are already being reviewed in order to check the biosecurity measures, inform those responsible for the birds of the risk and the importance of avoiding contact with wild animals, as well as checking the clinical stage of the animals in order to detect any suspicion of infection.
Similarly, from Agriculture they indicate that the finding in wild birds should not imply commercial restrictions on the movement of live birds or their products, "maintaining Spain the status of officially free of notifiable avian influenza."
1,199 outbreaks in 27 countries
The H5N1
subtype
is the predominant one in the current epizootic wave of HPAI present in northern and central Europe, where from last August 1 to December 27, 2021 a total of
1,199 outbreaks
have been reported in 27 countries, 507 in poultry and 692 in non-poultry (including wild).
At this time, and after confirming the presence of the virus in
Soses
, "the introduction and circulation of the HPAI virus in Spain can be considered as very high in areas of special risk and high in areas of special surveillance", of Hence, it has been decided to equate the biosecurity measures to be applied in areas of special risk of the country.
For this reason, at this time the use of birds of the orders
Anseriformes
and
Charadriiformes
as lures, the rearing of ducks and geese with other species of poultry, the rearing of poultry in the open air, the water tanks in the open air, is prohibited.
open air and the presence of poultry and other captive birds in animal concentration centers.
