Bernburg. Avian influenza has been detected in cranes at one location in the Salzlandkreis district – the Wiendorfer Teiche ponds in the Könnern area. Two of the six cranes found dead there were examined at the State Veterinary Medicine Investigation Office in Stendal. As expected, the avian influenza virus was detected in both animals.
The pathogen has so far always been identified as H5N1 in numerous cases found throughout Germany - this confirmation is still pending for the samples analysed in the Salzland district by the Friedrich Loeffler Institute on Riems.
The current death of the cranes is certainly "only" the tip of the iceberg. The ornithologist who observed the animals and informed the Salzland district of his discovery near Könnern on Tuesday this week also reported that the 400 or so cranes that spent the night there at the Großer Wiendorfer Teich have moved on. The birds, although in good nutritional condition, remained behind and were seriously ill. It is highly likely that they were acutely ill with the virus, which is highly pathogenic for waterfowl, and died on site.
After becoming aware of the observations on site, the veterinary office of the Salzland district flew over the ponds with the help of the German Life Saving Association (DLRG) and an infrared search drone. The discovered carcasses were collected, as far as recovery was possible, and sent to the rendering plant.
The veterinary office of the Salzland district, headed by official veterinarian Dr Christian Lutter, provides information: In the event that avian influenza is detected in wild birds, the district administration has the option of refraining from imposing obligations on poultry farmers. No compulsory stabling is currently being considered. Poultry trade and exhibitions are still permitted.
Irrespective of this, the risk of an outbreak of avian influenza in domestic poultry is extremely high in this situation. Those responsible in the Salzland district also want this to be emphasised explicitly. It can be assumed that infected poultry, whether waterfowl or chickens, will also be recognised as sick. Dead animals must therefore be clarified by a vet or sent for necropsy at least immediately. Accumulated losses must also be reported to the veterinary office in Bernburg.
The most likely source of infection - in addition to the purchase of infected poultry - is contact at poultry shows. Animals that have had contact with other flocks must therefore be separated for around 14 days before they are integrated into the flock.
Because wild birds are considered a source of infection that is difficult to control, contact with livestock must be avoided, even if it is only with the animals' faeces. The official veterinarian reminds keepers to also think about open watering places or feeding outdoors. The authorities therefore urge poultry to be kept indoors or at least protected from contact with wild birds and their droppings by bird-proof nets. Galoshes for entering stables are the best way to keep out the pathogen, which remains viable for a long time, especially in faeces.
