The virus encountered, of the H5N1 type, is « very contagious ». Six new outbreaks of avian flu were detected in duck farms in the south-east of the Landes, bringing the total number of farms concerned in the department to seven, we learned on Monday from the prefecture and the Chamber of Agriculture.
Five of them are located in Mant and one in Castelner, two towns bordering the Pyrénées-Atlantiques, where another outbreak of highly pathogenic avian influenza was confirmed on Friday in the town of Malaussanne.
All ducks slaughtered preventively from the first cases
According to Marie-Hélène Cazaubon, president of the Landes Chamber of Agriculture, all the ducks on these farms, « sheltered indoors since the start of their breeding », were slaughtered preventively from the first suspected cases on Friday.
A regulated zone has been defined in 34 municipalities in the Landes, in perimeters of 3 km (protection zone) and 10 km (surveillance zone) around these new outbreaks, the prefecture said in a decree.
« You have to be very vigilant, but also remain confident »
In the Landes, a first case of avian flu was confirmed on December 19 in Hastingues, further west in the department, after several other outbreaks reported in farms in the Nord department and one in neighboring Gers.
“Having the animals in a safe place does not prevent the introduction of the virus (into farms) but minimizes its spread. We have to be very vigilant, but also remain confident, because we are not in the same situation as the previous crisis, ”said Marie-Hélène Cauzaubon, herself a duck breeder.
No risk for the consumption of fatty liver
Brought by migratory birds that come into contact with poultry, the virus was first identified on November 26 in the North, in the town of Warhem where 160,000 laying hens were reared in buildings.
The prefecture of Pyrénées-Atlantiques, where three outbreaks of the virus have been detected since December 20, recalled Friday in a press release that « the consumption of meat, foie gras and eggs does not present any risk for humans. «
