Government data shows U.S. retail egg prices have declined for the first time since October. The average price for a dozen Grade A eggs fell to $5.12 in April after reaching a record $6.23 in March, according to the Consumer Price Index released on Tuesday. The average price of eggs of all sizes fell 12.7%, which was the steepest monthly decline since March 1984. Still, U.S. egg prices remain near record highs as a persistent outbreak of bird flu continues to wipe out egg-laying hens. April's store price was 79% higher than a year earlier, when the retail price averaged $2.86 per dozen.

Egg prices again reached a record high in February, as the bird flu continues to run rampant and Easter and Passover approach. The latest monthly Consumer Price Index showed a dozen Grade A eggs cost an average of $5.90 in U.S. cities in February, up 10.4% from a year ago. That eclipsed January's record-high price of $4.95. If prices remain high, it will be third year in a row consumers have faced sticker shock ahead of Easter on April 20 and Passover, which starts on the evening of April 12, both occasions in which eggs play prominent roles.
