Keep An Eye On HPAI

As the spring migration continues, highly pathogenic avian influenza continues to threaten wild and domestic birds.

In addition to the response to HPAI in poultry in certain states across the nation, federal agencies are also working with states on the emerging disease of HPAI in dairy cattle.

DATCP continues to urge all poultry owners to implement strong biosecurity measures to protect their birds from HPAI. ​As a reminder, signs of HPAI in infected birds include:

  • Lack of energy or appetite
  • Decrease in egg production; soft, misshapen eggs
  • Purple discoloration of wattles, comb, and legs
  • Difficulty breathing
  • Runny nose, coughing, sneezing
  • Stumbling or falling down
  • Diarrhea
