During the autumn season, with significant bird migration, the risk of bird flu increases. The European Food Safety Authority (EFSA), through the #NoBirdFlu campaign, reiterates key preventive measures. These include limiting access to farms, maintaining strict hygiene protocols, regular cleaning and disinfection, keeping wild birds and other animals separate from poultry, and housing different poultry species apart. Farmers are advised to contact their veterinarian if they observe any signs of illness in their animals.
The new Shamonda-like virus, belonging to the orthobunyavirus family, has recently been detected in ruminants in several European countries, including Belgium on multiple cattle farms. Transmission is suspected to occur via midges (Culicoides), with the exception of mother-to-fetus transmission during pregnancy.
In cattle, the virus can cause symptoms such as fever, lethargy, reduced activity, a sudden drop in milk production, and sometimes acute diarrhea. Pregnant animals are at risk of abortion, congenital abnormalities, or premature or stillbirth.
Farmers noticing unusual symptoms or unexplained health problems on their premises are urged to contact their veterinarian immediately for advice and diagnosis.
