Last Friday, it was discovered the mild from the Avian influenza in a tamfugl crew on a farm in Tr?gstad.


50 geese, ducks and chickens are killed and destroyed.

The Norwegian Food Safety Authority has established a quarantine zone for at least one kilometers area around the farm. In this area are several other Poultry producers.


It's taken samples of the birds on all farms in the vicinity and the answers to these is expected today.

According to the Norwegian Food Safety Authority should not sign that the infection will have spread to neighboring farms, but farms are still subject to strict restrictions.

This means that they are not allowed to deliver either egg or meat before the answers are.

In November, it was gjenom led a large emergency exercise to fight Avian influenza in ?stfold.

Press release Norwegian Food Safety Authority

No positive tests for the Avian influenza

Published: 08.12.2008 Last update: 08.12.2008

Samples have been taken in Poultry flocks in the risk zone in Trøgstad are all negative for lowpathogen Avian influenza type H5 and H7.

In two tests are made of different influensavirus. These samples studied further.

Restrictions on the original, infected and crew at risk will be retained for 42 days. This is to ensure that infection does not spread in the zone. Handling of such outbreaks is subject to international obligations and EEA regulations.

Restrictions means that the slaughter of Poultry and sales of eggs from these herds will be governed by specific conditions. These restrictions put in place to prevent smittespredning to other Fjørfehold. Meat and eggs from these herds are not dangerous to eat.

The Norwegian Food Safety Authority responded with restrictions and since the killing of the crew and disinfection of the environment Friday when it was noted lavpatogen Avian influenza type H7 in a hobby flock in Trøgstad.

Poultry flocks for about a kilometers radius was also ordered restrictions, and attempts were taken out on Friday. There are three commercial producers and some hobby herds in this risk.

- Inner Østfold is a district with many commercial Poultry producers, and it will be very serious if any of them had received the Avian influenza infection in their facilities, "said distriktssjef Kirsti Ullsfoss by the Norwegian Food Safety Authority distriktskontor for Inner Østfold and Follo.

She stressed that the Norwegian Food Safety Authority also in the future will continue to remove the monitoring samples, and following them up routine with the necessary means. - It is an important part of our preparedness to prevent the spread of animal diseases, among other things, "she said.

Re: Norway: Avian Influenza in poultry : H7

Regarding the previous press release:

Today's negative testresults refer to samples of surrounding farms, in the 1-km riskzone. It means no further contamination, no spreading to other farms.

So probably we are talking about an isolated case. If not for routine testing, nobody would have known.

This case makes clear routine testing is a good thing.

We will hear more about "a different influenza virus" , found in two testresults, further research is done on the samples.

NORWAY, LOW PATHOGENIC AVIAN INFLUNZA IN POULTRY (12/11/2008) [ECDC Health Content]

AVIAN INFLUENZA ? ANIMAL HEALTH - NORWAY

5th December 2008

An occurrence of Low Pathogenicity Avian Influenza in birds has been reported to the OIE by the Norwegian authorities. The affected animal was a single bird from a mixed flock of 50 (including 39 hens and 11 geese) in the Ostfold region of Norway.


The date of the start of the report is 17/11/2008 and this was confirmed positive 18 days later in the laboratory.

This was not an outbreak, rather it was detection of an infection through routine testing of poultry.

Routine control measures were applied and the whole flock was culled.

ECDC comment:
Low pathogenicity avian influenza refers to how an avian influenza virus behaves or is predicted to behave in birds, and hence does not give an indication of the pathogenicity in humans, or the ability of the virus to transmit to humans.

To date, avian influenza viruses have had only limited potential to transmit from birds to humans.

However, several cases have demonstrated that such low pathogenic viruses can pose some public health risk (1,2), and hence ECDC has highlighted the need for all people who have had some potential exposure to infection to take appropriate precautions to limit the public health risk.

It can be argued that low pathogenicity strains pose a different public health risk compared to high pathogenicity because they usually cause mild symptoms in the birds , and hence persons handling infected birds may not be aware of their disease status.

Infections such as the one in Norway can be expected to happen sporadically in EU and EEA flocks and will then occasionally be detected like this.

The strong animal health surveillance systems in the EU/EEA Member States mean that such infections probably have a higher likelihood of being detected compared to countries with weaker surveillance, which reduces the potential of infection becoming established in poultry.
