Questioned by the DGAL, the Nationwide Company for Meals Security (Anses) considers as possible in Brittany the contamination by H5N1 of the resident wild avifaunawhich might represent a everlasting reservoir. This similar virus-carrying wild birds flow into intensely within the Pays de la Loirewith the chance of epizootics within the occasion of extension of the outbreaks detected in areas dense with livestock (Areas vulnerable to dissemination: ZRD).

Routine measurements

Already positioned in Non permanent Wildlife Management Zones (ZCT FS), Brittany, the Pays de la Loire and the 2 Sèvres will stay so so long as the avifauna presents a danger of introduction into breeding. In different phrases, a number of months…

ZCT FS standing implies that the position of poultry is just doable in farms adhering to the salmonella well being constitution (laying and breeding sector) or having a favorable biosecurity audit (meat farming).

Alternatively, waterfowl farms are topic to 2 weekly self-checks (swabs and swabs)); in addition to the self-check earlier than motion within the earlier 48 hours.

Measures within the occasion of suspicion or an outbreak

In case of suspicion, a brief restricted space (ZRT) is established over a minimal radius of three km. All motion of animals and merchandise is prohibited and no animal could also be killed.

In case of affirmationthe ZRT turns into a restricted space: 3 km safety zone and 10 km surveillance zonefor 3 weeks in ZP and 4 weeks in ZS. Biosecurity is strengthened with self-checks twice per week in palmipeds (cloacal swabs from corpses, dry swabs) and breeders (cloacal and tracheal swabs from residing and lifeless animals, blood samples, swabs at every egg assortment). Set-ups are prohibited, in addition to the elimination of animals from farms, apart from derogations. The crawl house might be prolonged for 3 weeks after the lifting of the restricted areas. Looking actions (transporting decoys, transporting and searching recreation) are prohibited.

A brand new truth, preventive depopulation, or an early cull, is utilized for batches positioned round outbreaks (besides breeders), when the latter are positioned in a ZRD or lower than 30 km from a ZRD.

All species are slaughtered inside the radius of 1 km ; solely turkeys and waterfowl between 1 and three km; between 3 and 10 km the waterfowl are reformed in anticipation and the turkeys beneath reserve. In all circumstances, the elimination is carried out in a single go.

Utilized earlier than figuring out the well being standing of the batches vis-à-vis the H5 viruses, preventive depopulation could have a powerful “dedensifying” impact conducive to decreasing the chance of epidemic runaway. Supplied that it’s carried out rapidly, with human and materials sources tailored to the circumstances.

Monitoring obligation from 250 poultry

A decree printed within the Official Journal on October 29 widens surveillance linked to avian influenza to farms with 250 poultry, in comparison with 1,000 beforehand. The three new alert standards that ought to encourage reporting to the well being veterinarian have been launched. It’s :

  • The three-fold enhance in regular each day mortality;

  • The lower in each day water or meals consumption by greater than 25%;

  • Any egg drop of greater than 15% in sooner or later or greater than 5% per day for 3 consecutive days

Within the occasion of a “average” danger, this decree additionally extends to those small farms positioned within the densest breeding basins (areas vulnerable to dissemination) the strengthened biosecurity measures already utilized in wetlands favorable to migratory birds (areas at explicit danger). Particularly the duty to shelter poultry.

The decree permits the transport and launch of recreation birds (after medical evaluation and serological screening) within the occasion of “average” or “excessive” danger, whereas they had been beforehand prohibited.
