The European Food Safety Authority (EFSA) called on European Union (EU) countries this Monday to strengthen safety measures against bird flu, following warnings of new outbreaks.
Between September 6th and November 14th, 1,443 outbreaks of avian influenza in wild birds were detected in 26 EU countries, the highest number since at least 2016, according to EFSA data.
This authority called on countries to reinforce surveillance and adopt biosafety measures, in accordance with published recommendations.
Among the published recommendations is also the confinement of birds in areas affected by avian influenza, the special monitoring of stopping points along the migratory routes of wild birds and the avoidance of artificial feeding of wild birds.
Wild bird carcasses must be removed immediately to avoid the risk of contagion with other species.
In turn, hunting must be reduced, as well as the use of drones or other activities that could disturb the birds.
In Portugal, a new outbreak of bird flu was detected in Ramalhal, in Torres Vedras, in a domestic poultry farm with geese, ducks, guinea fowl and quails, DGAV announced on Monday.
