The world animal health organization, OIE, says the United States has informed it of a third California farm infected with avian influenza.
So far the U.S. Department of Agriculture has said nothing about it, other than informing the OIE which posted the information on its website.
This case is a different strain of avian influenza – H7N3 – which is in the low pathogenic category. About 61,000 turkeys were infected a farm in Merced County.
The other cases in California, Oregon, Washington State, Idaho, Minnesota, Missouri and Arkansas are a strain in the high pathogenetic category.
In the latest case in California, a commercial tom turkey flock exhibited coughing with a slight increase in mortality, according to the OIE report. The other strain involved in outbreaks is much more deadly, wiping out entire flocks in a few days.
The infected premises were placed under quarantine following preliminary findings and an epidemiological investigation was initiated. Follow-up surveillance and testing on 10 nearby farms found negative results.
USDA’s Animal and Plant Health Inspection Service provided the information to OIE on Tuesday, the report said.
