Avian influenza warning: outbreaks in the Rostock district require vigilance!

Avian influenza warning: outbreaks in the Rostock district require vigilance!

The news is now in black and white: two outbreaks of avian influenza were detected in Mecklenburg-Western Pomerania last week. This confirms the current risk assessment by the Friedrich Loeffler Institute (FLI), which indicates a constant risk of entry of highly pathogenic avian influenza viruses (HPAI) of the H5N1 subtype. What is particularly worrying is that another outbreak occurred earlier this month in laying hens in Schleswig-Holstein. In view of these developments, it is essential to further intensify the monitoring of poultry populations.

The FLI, which assessed the situation on September 9, 2025, currently classifies the entry risk as low. However, caution is advised because free-range animals are particularly at risk because it is almost impossible to avoid contact with wild birds. With the increased density of wild birds that can be expected in many regions due to bird migration, close monitoring is required. The FLI recommends recognizing signs of infection early in order to contain the spread of the disease and take appropriate measures.

Avian influenza and its causes

Avian influenza, better known as bird flu, is a virus that occurs regularly in Germany, primarily due to the H5N1 subtype. The problem is further compounded by sporadic cases of HPAI in wild birds. A look back at the period from November 2024 to February 2025 shows that there were 40 HPAI outbreaks in poultry in Germany. But don't worry: The risk to humans can currently be classified as low, even if HPAI H5N1 is considered a potential zoonotic pathogen.

However, the challenge remains great - since around 2024, cases have been known in the USA where avian influenza has also spread to dairy cow herds. The udder of infected dairy cows appears to be a suitable breeding ground for the virus to multiply. Fortunately, there is currently no evidence of such transmission to cattle or in milk production in Germany. However, the situation is being closely monitored and the relevant authorities are recommending precautionary measures for travelers to the USA and for domestic pet owners.

Precautions and need for action

Hygiene and protective measures are of paramount importance in the fight against avian influenza. Every poultry farmer is legally obliged to follow biosecurity measures. When coming into contact with dead birds, precautionary measures should be strictly observed to avoid possible infection. In addition, there is close cooperation between various institutions in Lower Saxony to assess the situation and identify possible needs for action. This is happening not only at the national level, but also at the political level.

The fight against the animal disease in Germany is based on the Avian Influenza Ordinance, which ensures a harmonized approach within the EU. A preventative HPAI vaccination of poultry is currently being examined in Germany in order to be able to better manage future outbreaks. The topic remains highly topical and requires the attention of farmers, experts and politicians in order to keep the partial situation under control.

What remains important is that regular checks of biosecurity measures and raising awareness among all those involved are essential in order to prevent the spread of avian influenza in a timely manner. A close eye on the health situation and close communication in agriculture and animal husbandry are now urgently required.
