The Newcastle disease situation in Sweden has been resolved, according to a report from the World Organisation for Animal Health (WOAH).
The report, which was issued on February 9, stated that on January 16, veterinary officials were notified that a producer in Johannishus noticed abnormalities in a layer flock, including decreased egg production and changes in the egg shells. However, no clinical signs of increased mortalities were detected.
Gene sequencing and real-time polymerase chain reaction testing was done on samples from the flock in question, and those tests came back positive.
All 5,000 chickens in the flock were depopulated on January 30. A 3-kilometer protection zone and a 10-kilometer surveillance zone were established.
Other control measures put in place included movement control, disinfection of the premises, and official disposal of carcasses, byproducts and waste.
Prior to this case, Sweden’s last case of Newcastle disease occurred in November 2022 and involved 14,000 birds.
Other countries to deal with recent cases of Newcastle disease include Norway, Russia and Israel.
Sweden also dealing with avian influenza
In addition to Newcastle disease, veterinary officials in Sweden have also been occupied with cases of highly pathogenic avian influenza (HPAI). The most recent case listed on the WOAH website involved wild birds and was confirmed on January 9.
