NC State veterinarians explain highly pathogenic avian influenza, which can kill more than 90% of the poultry it infects and is spread by migrating waterfowl. Two North Carolina commercial poultry farms have been infected so far this year, after a year of mainly small backyard cases.

Renewed commercial infections in a major poultry state raise the risk of larger flock losses, which would cut feed demand and add to egg and chicken price pressure.
