Grocery stores across the U.S. have started limiting the amount of eggs customers are allowed to purchase each day, as prices soar, and an outbreak of avian flu continues to slow the nation's supply of the fridge staple. 

According to the Associated Press, Trader Joe's now has a daily "one carton per customer" policy in place for eggs, which applies to all of the grocer's U.S. locations. Although Kroger doesn't have nationwide limits in place, the grocery giant says that a handful of regional divisions are imposing two-carton limits at select locations. Walmart has also capped daily purchases of its bulk 60-egg cartons to two per customer, while Costco is limiting its shoppers to three packages of eggs per day, which the warehouse retailer sells in two and four-dozen cartons.

“Although supply is very tight, we’re working with suppliers to try and help meet customer demand, while striving to keep prices as low as possible,” Walmart said in a statement to the Associated Press. 

U.S. farms have had to cull millions of egg-laying hens since the fall of 2024, as avian flu has spread through flocks in Maryland, Ohio, Indiana, Missouri, Washington and Arizona among many others. The average price of a dozen eggs spiked 37% year-over-year in December 2024, and the U.S. Department of Agriculture expects prices to continue on that trajectory in the months to come, predicting an additional 20% increase by the end of 2025.
