Bird flu in poultry laying crew in Nyk?ping
Bird flu has been detected in one laying flock in Nyk?ping. Test results from the National Veterinary Institute show that the herd is infected with the virus type H5N8. Agriculture has imposed restrictions in the area to avoid contamination. This type of virus that has been circulating in birds in autumn and winter has never infected humans.
Avian influenza type H5N8 has been circulating in Europe during the fall and winter, in Sweden, Denmark, Finland and several countries on the continent. A laying crew in southern Sweden was hit in December 2016 by the bird flu. Although a number of backyard flocks, a zoo and a number of wild birds have suffered.
- A couple of weeks ago we reduced the level of protection in Sweden from 2 to 1. This means that poultry and other domestic birds must go fenced outdoor with water and feed under cover. The affected farm is free-range laying hens go indoors, and it is unclear where the infection came from, says Karin ?hl on Agriculture.
Protection and surveillance zone around the infected farm
Regarding the infected laying hens crew in Nyk?ping Agriculture has now decided on the refusal of access, and where there is specific restrictions, which means that no animals or animal products may leave or enter the yard.
Agriculture has also decided to establish a protection zone with a radius of three kilometers around the farm and a surveillance zone of 10 km radius. In the protection zone, particularly the following restrictions:
- To counter the spread of infection, parts or all laying hens crew to be killed, and the plant is blocked and will then be cleaned up. This of course means a strain on the animal's owner. Spread the infection among domestic birds, it can mean huge costs for society and unnecessary suffering of the birds affected, says Karin ?hl.
Found naturally in wild birds
Bird flu comes in many varieties and is very contagious among birds. Milder variants of the virus occurs naturally among wild birds, especially of seabirds.
- The new case is the first confirmed in S?dermanland, wild birds included. This confirms that the bird flu is still circulating in Sweden. Thus, the risk for Swedish poultry remained elevated. It is therefore important that both poultry producers hobby bird owners have good infection control procedures, and as far as possible prevents both direct and indirect contact between domesticated and wild birds, says Karl St?hl at SVA.
Still important to prevent contact with wild birds
The warmer weather of spring brings with it makes the bird flu virus has been difficult to survive in the environment. However, there is still a risk of spreading mainly from aquatic birds. Therefore, it continues important to have good management practices and to the extent possible to prevent contact with wild birds.
Do not ever infected the human
- Avian influenza type H5N8 has never infected the man despite several years been among wild birds and caused outbreaks in domestic poultry flocks in other countries. Therefore, we believe that the risk of humans being infected in Sweden is almost nonexistent. But there are always good reasons to be cautious in case of contact with dead birds and animals found in the wild because they also can carry other infections, says Anders Wallensten at the Public Health Agency.

- Poultry and other captive birds must be kept indoors.
- It is forbidden for unauthorized persons to enter the stables in poultry and other birds.
- It is prohibited to transport poultry, live birds, hatching eggs and poultry products from poultry farms.
- To counter the spread of infection, parts or all laying hens crew to be killed, and the plant is blocked and will then be cleaned up. This of course means a strain on the animal's owner.
