Denmark turns poultry biosecurity into a nationwide housing routine

Denmark is turning poultry biosecurity from a recommendation into a verifiable routine. On 6 November, the Danish Veterinary and Food Administration raised the avian-influenza threat level from medium to high. From Monday, 9 November 2026, poultry and other captive birds must be housed indoors, kept under cover or otherwise protected nationwide.

The measure responds to a growing number of detections in wild birds in Denmark and neighbouring countries, as well as three recent outbreaks in poultry holdings. For businesses, the rule is more than keeping birds indoors: feed and water must be provided under cover so that wild birds cannot access them, and surface or rainwater available to birds must not be contaminated with wild-bird droppings.

Defined exemptions apply to small chicken enclosures and, under conditions, to duck and goose holdings. The operational principle remains the same: physically separate contact points. Animal shows, exhibitions and competitions involving poultry or birds are also generally prohibited across the country.

For the poultry-meat chain, the Danish case shows that biosecurity is not merely a barn-door issue. Covers, water, feed, footwear, entry points and records all alter the probability of virus introduction. The measure does not by itself constitute a trade restriction on meat, but it can change planning for outdoor-access systems, movements and events. Procurement, production, logistics and communication therefore need to work from the same risk map and documented procedures.
