On Wednesday, the U.S. Bureau of Labor Statistics shared its latest update on consumer prices, showing that the average cost of a dozen large grade A eggs increased nearly $1 in a single month—to $5.89. February's price jump is the largest since 1980–even after adjusting for inflation and beats the record set by January's price data.
This historic run of egg-price surge stems from H5N1 avian influenza—or bird flu—hitting poultry producers hard this winter. The increase came after a new version of the virus emerged in wild migratory birds in September 2024 and then jumped to domesticated fowl.
