An avian influenza has been detected in a flock of turkeys in eastern South Dakota's Beadle county. The H5N2 strain, also known as bird flu, is affecting poultry in multiple states including Minnesota.

USDA's Animal and Plant Health Inspection Service says the flock of 53,000 turkeys has been quarantined and considers the risk to people to be low.

The birds will be killed to prevent the spread of the disease.
