Record high wholesale egg prices in the U.S. are being driven by an outbreak of bird flu impacting laying hens and consumer demand for holiday treats. Prices have surged to $5.57 a dozen in the Midwest and $8.85 in California, marking a significant increase from the previous year. The price hike is exacerbated by inflation and potential tariffs, with retailers delaying passing on higher costs to customers. The outbreak has resulted in the death of nearly 123 million poultry, leading to a decrease in the egg-laying flock and production. The situation is further complicated by concerns over wild birds spreading the virus and the potential for delivery trucks to carry the virus from dairy farms. Human cases of the virus have been reported, though most have been mild. The USDA is funding research into vaccines to protect poultry and cows from the bird flu and is considering continuing support for vaccine development under the Trump administration.
