US - Thirteen new outbreaks of H5 highly pathogenic avian influenza have been added to the official count by the USDA - all in commercial turkey flocks in Minnesota.
USDA's Animal and Plant Health Inspection Service (APHIS) has added a further 13 outbreaks to its list of Avian Influenza Findings since yesterday.
All these outbreaks were in commercial turkey flocks in Minnesota – in the counties of Meeker (three outbreaks), Stearns (three), Kandiyohi (five), Redwood (one) and Otter Tail (one).
At least 430,300 birds are known to have been affected but the number will be higher as the bird count is pending in three of the outbreaks.
All these were in the area of the Mississippi flyway for migrating wild birds and were caused by the H5N2 variant of the virus.
