‘All hands on deck’: Bird flu in US poultry puts state cooperation to the test

Unusually late migration season means poultry operations may continue to see H5N1 outbreaks, officials say

Maryland has detected bird flu among three different commercial poultry flocks in the past week, marking the state's first outbreak in more than a year. The discoveries come shortly after the establishment of a joint command with Delaware following the latter state's detection of H5N1 in two other poultry operations.

Although the deadly bird flu has circulated in North America since 2022, the past few months have been especially brutal for the poultry industry. More than 20 million egg-laying hens died in the fall, the worst rates since the outbreak began, and egg prices have risen as a result.
