Trader Joe’s and other grocers are limiting the number of eggs customers can buy across the U.S., citing limited supply caused by the ongoing bird flu outbreak.

A deadly outbreak of avian flu has wiped out nearly half of the egg-laying hens in the U.S., leaving grocery store aisles empty, driving up prices and forcing retailers to limit purchases to curb hoarding.

As egg prices soar due to the ongoing bird flu outbreak, Trader Joe's is limiting customers to a dozen eggs per purchase per day. Signs have been erected at Trader Joe's stores across the country, informing customers that they will be limited to a single carton of a dozen eggs per day to "ensure a consistent supply for all customers."
