An outbreak of avian flu was detected in a duck farm in Landes, the main department producing foie gras, for the first time since the epizootic last winter, we learned on Sunday from the chamber of agriculture and the prefecture.

"It is located in Hastingues", on the edge of the Pyrénées-Atlantiques, told AFP Marie-Hélène Cazaubon, president of the Landes chamber of agriculture. "The clinical signs (observed Friday) left no room for doubt and it was decided to depopulate the farm (from Saturday) without waiting for the results" Sunday of the final analysis.

This confirmed a "contamination by the highly pathogenic avian influenza virus of the H5N1 type" , specified in a press release the prefecture, which has set up around the outbreak a protection zone with a radius of 3 km and a surveillance zone with a radius of 10 km.

The affected farm is located in an area "known to be the first line of introduction of the virus by wildlife", according to the prefecture.

This outbreak is the second detected in the South-West, the main foie gras production area, since the avian flu epizootic which affected 15 departments last winter and led to the slaughter of 3.5 million poultry. 'breeding.

The first was detected this week in Manciet (Gers). It was then the eighth French breeding affected by the H5N1 virus, after seven outbreaks reported in the Nord department since November 26...

Avian influenza in the Landes: a contaminated farm in Hagetmau, the virus enters Chalosse
By Yoann Boffo - y.boffo@sudouest.fr
Posted on 01/08/2022 4:38 PM
The H5N1 virus has been gaining ground for several weeks in the south-east of the Landes. He entered the Chalosse zone at the end of the week, where the ducks are numerous. Suspicious cases multiply between Hagetmau and Saint-Sever

The moment was dreaded by all players in the industry. The highly pathogenic avian influenza virus (H5N1) is now present in Chalosse. It was detected in a farm in Hagetmau, Thursday, January 6, after reaching the neighboring municipalities of Arboucave and Puyol-Cazalet the previous days. The fat ducks in question were to be euthanized over the weekend.

Last year, the entry of the virus into Chalosse, where the majority of palmiped farms are concentrated, was synonymous with loss of control of the epizootic. Avian influenza has progressed from the borders of the Landes and Béarn since the detection of many cases around Malaussanne and Mant on December 27. In just over a week, the number of outbreaks has increased from 9 to 33, Friday evening January 7.

Suspicions multiply

This figure could quickly increase now and the race against avian influenza once again lost. Suspicious cases have been reported in several municipalities (Castelnau-Tursan, Cazères-sur-l'Adour, Classun, Buanes). Until the heart of Chalosse, where checks were underway in Gaujacq, Brassempouy, Eyres-Moncube and Saint-Aubin, just a few kilometers from Saint-Sever.

Since Friday, January 7, the health services have carried out a systematic slaughter of healthy ducks located within a radius of three kilometers around the outbreaks (protection zone). Friday evening, 43 municipalities were concerned. These tens of thousands of birds are taken, after a negative test, to the Méthalandes site in Hagetmau, and taken care of by the company GT Logistics.

A necessity to remove them quickly, even if moving animals presents a risk of dissemination. On several occasions, ducks that tested negative initially turned positive at their point of arrival. This is the difficulty of the equation...

Farms are suspected of harboring the H5N1 virus in Cachen and Saint-Geours-de-Maremne. The prefecture has set up temporary restricted areas in six municipalities on Thursday evening January 13

Hitherto contained in the south-east of the department , has the avian influenza virus managed to make its way to Haute Lande and Maremne? This is the fear of the authorities. The Landes prefecture issued orders following the discovery of suspected cases in farms in Saint-Geours-de-Maremne and Cachen.

The authorities set up temporary restricted areas on Thursday evening January 13. The time to carry out the necessary analyzes, preventive measures apply. The movements of waterfowl and poultry are notably limited there. The municipalities of Bélis and Arue are concerned around Cachen. In the vicinity of Saint-Geours-de-Maremne, the area extends over Rivière-Saas-et-Gourby and Saubusse.

In the south-east of the department, the epizootic continues to progress inexorably. Sources of contamination have been discovered in recent days in municipalities so far spared: Sainte-Colombe, Caupenne, Maylis, Bordères-et-Lamensans, Saint-Agnet, Coudures, Larrivière-Saint-Savin, Baigts and Poyartin.

The preventive slaughter of all waterfowl farms, located less than 3 kilometers from the outbreaks, and of poultry, within a radius of 1 kilometer, is continuing. Friday evening, the Landes had a total of 108 contaminated farms since the start of the crisis. The number is changing hour by hour.

Avian flu in the Landes :: More than 300,000 animals slaughtered in the Landes
]
January 16, 2022

The epidemic intensifies in the Landes

The bird flu epidemic intensifies in the Landes. Already more than 300,000 animals have been slaughtered on farms. Sanitary measures are being reinforced.

Since its appearance for the first time in the Landes department in Hastingues on December 17, and despite the stabilization of this first zone, highly pathogenic avian influenza of the H5N1 type continues to progress from outbreaks that appeared in the town of Malaussanne (Pyrénées-Atlantiques) then Mant (Landes). On January 14, 2022, 110 H5N1 outbreaks were confirmed and 33 suspicions of avian influenza are awaiting confirmation of their highly pathogenic nature by the National Reference Laboratory.

When slaughterings are carried out on the farms, the animals are euthanized either by a team led by a private veterinarian and technicians from the veterinary services for small farms, or by the company GT Logistics for farms the most importants. To date, nearly 170,000 poultry and 115,000 waterfowl have been slaughtered on farms. To slow the progression of the virus, the preventive depopulation of farms is organized in two different ways. On the one hand, by the installation on January 7 of a high-capacity depopulation platform, the operation of which was entrusted to the company GT Logistics, under direct contract with the Ministry in charge of Agriculture. Nearly 260,000 waterfowl and 30,000 poultry were euthanized in this way. On the other hand, within the slaughterhouse of Saint-Sever which was the subject of a requisition by order of the prefect of the Landes from January 13 for several days a week. 30,000 poultry have been euthanized there to date.

To understand the origin of the appearance of the first contaminations and the causes of the spread of the H5N1 virus, an agent from the Regional State Directorate in charge of agriculture and 4 agents from ANSES (National Health Security Agency Food National) provide their support to conduct an epidemiological study. The continuous increase in the number of contaminated or suspect farms, the various regulated areas are changing almost daily. To date, nearly 50 municipalities are in the protection zone (3 km around the outbreaks), 80 in the surveillance zone (3 to 10 km around the outbreaks) and 20 in the temporary control zone (10 km around suspect farms in awaiting confirmation by the NRL). In addition, an additional restricted area set up on January 1 to delay the placement of animals and reduce their density is extended.

Avian flu back in the Landes, a duck farm affected near Peyrehorade

Landes
Of France Blue Gascony , France Blue Basque Country , France Blue

Through Renaud Biondi-Maugey

The highly pathogenic avian influenza virus was detected on a farm in Cagnotte (Landes), south of Dax. Thousands of ducks will be slaughtered.

This is an announcement feared by the entire fatty duck industry in the Landes: bird flu is back in the department. The virus was detected in a duck farm in Cagnotte (Landes), a town located 7 kilometers north of Peyrehorade. During the night of this Saturday 21 to Sunday 22 January, the Landes prefecture published an order on the internet to designate a regulated perimeter around the infected farm.

A protection zone in six municipalities

A protection zone, including six municipalities (Peyrehorade, Cagnotte, Belus, Cauneille, Orthevielle and Saint-Lon-les-Mines), has been set up within a radius of 3 kilometers around the outbreak farm. In Cagnotte, the slaughter of ducks in the farm affected by avian flu was ordered by the authorities, said on the morning of this Sunday Marie-Hélène Cazaubon, president of the Landes chamber of agriculture, interviewed by France Bleu Gascony. The Landes prefecture confirms that " 5300 ducks ", present in this breeding, are slaughtered " this Sunday ".

It is not known, at this stage, if preventive slaughter is ordered in the other farms of the six municipalities of the protection zone.

And 21 municipalities under surveillance

A surveillance zone including 21 other Landes municipalities (including Pouillon, Bénesse-lès-Dax, Port-de-Lanne or Sorde-l'Abbaye) has also been set up within a radius of 10 kilometers around the outbreak. Finally, in an area of 10 additional kilometers, 35 municipalities (including Dax, Habas, Pomarez, Narrosse, etc.) are placed in additional restricted areas. Within these zones, animal movements are restricted and the rules are very strict for duck farmers. The authorities want to prevent the spread of the virus.

This is the first case of the season in a Landes farm. While bird flu has been spreading for several months all over France, and especially for a few days in the Gers, the Landes department remained spared until then. This is no longer the case.

Landes: avian flu back in the department, a farm affected in Bordères-et-Lamensans
Borderes-et-Lamensans

By Marion Dambielle-Arribage
Wednesday, May 10, 2023 at 9:42 a.m.
By France Blue Gascony

The results of the analyzes fell this Wednesday, May 10: avian influenza was spotted in a duck farm in the town of Bordères-et-Lamensans, in the Landes. It is consternation within the sector.

Since Monday, May 8, clinical signs and the first unfavorable test results raised fears of the worst. The final results fell this Wednesday, May 10: a case of highly pathogenic avian flu was detected in a duck farm in Bordères-et-Lamensans, near Grenade-sur-l'Adour, announces the Landes prefecture to France Bleu Gascony.

Consternation and misunderstanding

There is consternation within the sector: this winter, the Landes department was almost spared by avian flu . Only one case was proven, in an autarkic breeding of Cagnotte , and it was in January. The “Adour Plan”, which aimed to set up a virtual crawl space in 68 Landes municipalities during the period most at risk , that is to say from December 15 to January 15, seemed however to have borne fruit. This case of avian influenza, in a breeding of ducks ready to force-feed where, according to our information, the waterfowl were confined, therefore raises many questions and greatly worries professionals.

“We are appalled” reacts Marie-Pierre Pé, the director of CIFOG, the Interprofessional Committee for Foie Gras Palmipeds. "It's the most total misunderstanding. It's unprecedented at this time of year, a time that was not considered a risky time. After the success of the Adour Plan this winter, we thought we were relatively off the hook."

Epidemiological investigation

It now remains to find explanations: "This raises a lot of questions for us" recognizes Marie-Pierre Pé. "We are expecting a lot from the epidemiological investigation, in order to understand how the virus could have arrived on this farm , where the ducklings were not in the open air. They were confined."

A surprising return

This case in the Landes comes as the virus reappeared in the Gers last week, after several months of calm. Two outbreaks were detected in Manciet and Couloumé-Mondebat. On the other hand, a suspected case in Eauze turned out to be negative on Tuesday.

A resurgence of this disease does not fail to surprise, whereas the virus previously struck farms rather in winter, and not in the middle of May. So much so that the Ministry of Agriculture had decided to ease the containment measures at the end of April as part of a reduction in the level of risk in the country.

Avian flu is spreading in the Landes, contamination from local wildlife?

Landes
By Renaud Biondi-Maugey
Friday, May 12, 2023 at 10:38 a.m.
By France Blue Gascony , France Blue

Gascony is facing an unexplained outbreak of bird flu, with four outbreaks in Landes and 17 outbreaks in Gers.

The bird flu epizootic is gaining ground in the Landes, with a total of four farms now infected in the department, this Friday, May 12, two more than yesterday. After Bordères-et-Lamensans then Benquet earlier in the week, it is now farms in the municipalities of Aire -sur-l'Adour and Cazères-sur-l'Adour that are concerned. Authorities have ordered the slaughter of tens of thousands of ducks in an attempt to limit the rapid spread of the disease.

This epidemic outbreak, in the middle of May, outside the risk period, is unprecedented and raises many questions. In the Gers , a neighboring department, 17 outbreaks were detected, according to a count established by the prefecture at the end of the day Thursday. Massive preventive slaughter of ducks within a radius of 10 kilometers around the outbreaks have been ordered in the Gers in an attempt to stem the spread of the virus.

How to explain such an epidemic resurgence?

Migratory birds, which are often the vector of transmission of avian flu, cannot this time explain this epidemic outbreak, since the migration season is over. The almost simultaneous appearance of these cases of bird flu in duck farms in Gascony is therefore deemed " incomprehensible " by the Landes Chamber of Agriculture. For ANSES, the national agency for food, environmental and occupational health safety, the contamination could come from local fauna . It would then be an endemic situation, a virus which remains present in the region and which reappears at any time, depending on the climatic conditions.

" What is possible is that the local wildlife has kept these viruses and that we have a very infected environment," said Charlotte Dunoyer, scientific director of animal health and welfare at ANSES. There may be a " permanent exchange between outbreak farms which infect wildlife which reinfects farms which then reinfect wildlife", she believes.

To avoid an uncontrollable spread of the epizootic, ANSES calls for "absolute vigilance" and "extreme speed in dealing with outbreaks".

Dozens of municipalities under restriction in the Landes

To avoid, or in any case limit the spread of the virus, restriction zones of 3 kilometers, 10 kilometers and 20 kilometers around the outbreaks have been established. In each of these areas, duck farmers are subject to specific measures. The movements of ducks are limited and controlled there.

Avian flu in the Landes: 200,000 ducks are being slaughtered

By Lise Dussault
Monday, May 15, 2023 at 6:22 p.m.
By France Blue Gascony

For the past few days, the Landes have been facing a new episode of avian flu and the numbers are only increasing. This Monday afternoon, the prefecture, which made a point, had six homes, as well as two suspicions. 70,000 ducks have already been slaughtered.

The numbers are only increasing day by day. While last Friday the Landes had four confirmed outbreaks of avian flu , we are now at six. The prefecture of the department made a point this Monday afternoon. Six homes therefore, in five different towns : Bordères-et-Lamensans , Benquet, Cazères-sur-l'Adour, Aire-sur-l'Adour and Le Vignau. All are located in this border area with the Gers. In an attempt to curb the spread of the virus, 70,000 ducks have had to be slaughtered in recent days. It will be necessary to euthanize 200,000 in total.

The contamination would come from the Gers

At the same time, scientists continue to search, to try to understand, how and why the Landes find themselves confronted with such an episode. In the middle of May, it's unprecedented. Then the current variant is sequenced . If the results will only be known in a few weeks, the specialists have already noticed that it very much resembles that which had affected the Gers during the previous crisis. Conclusion: the virus had never disappeared.

Two possibilities: either the disinfection carried out in the neighboring department was not enough, or it was the wildlife that kept and transmitted the virus. If this second hypothesis is confirmed, it is worrying because it means that bird flu is now endemic , that it is constantly present, and therefore, can be caught at any time. Now, if not a bit of good weather to slow the circulation of the virus, in the sector, everyone is adamant. There is only one solution: the vaccine.

For the vaccine, there will be priorities

This is eagerly awaited and to save time, the State has already placed an order: nearly 90 million doses, for the whole of France (two per animal will be needed). Vaccines that are not yet ready, currently in production. A first is already approved, a second is about to be . But the DRAAF reminded us: the precious product will not be available before October.

As for the Covid, we will also have to prioritize. The first to benefit from it will be the breeding ducks indicates the DRAAF, "to ensure the continuity of the sector" . Then come the animals from the areas most at risk . So will the Landes be part of it? We can imagine it but it's too early to tell. Finally, the DRAAF warns that once the vaccine has been administered, breeders will have to monitor their ducks, make sure that everything is fine, that there are no side effects, as on a human. Monitoring which will have a very significant cost.

Avian flu: two new cases in the Landes, the profession is resigned

Landes
from Eric Ballanger
Wednesday, July 12, 2023 at 4:58 p.m.
By France Blue Gascony

The ducks have been slaughtered in the two affected farms in Saint Yaguen and Maylis, but other preventive slaughters could take place in the affected area.

The Landes department has already experienced an unprecedented outbreak of the virus in May. Spring is generally considered a bird flu risk-free period until then, but this year the virus crossed the seasons. After the consternation of the profession, today, the hour is rather with the resignation.

"We got used to the idea that avian flu no longer has a season, that it can strike at any time, that we have to live with this virus" sums up Marie-Hélène Cazaubon, the president of the Landes Chamber of Agriculture.

In fact, bird flu is no longer a winter virus. The Landes experienced an unprecedented outbreak last May. 25 outbreaks had been identified, the last in Miramont-Sensacq. Since then, we have had six weeks of peace. A certain fatalism seems to be settling in the profession even if the case of Maylis is particularly worrying, because it is located in Chalosse, the epicenter of the production of fattened ducks where the farms are very numerous and very close to each other.

“For the moment, the sector is hunkering down and clenching its teeth” recognizes Marie-Hélène Cazaubon. A whole profession now awaits vaccination, which many consider to be the only way to save the sector. This vaccination should begin in October.
