Trader Joe's and other retailers have moved to limit the number of eggs customers can buy as a result of the national shortage.

The U.S. Department of Agriculture recently said egg prices will likely continue to rise through the end of the year.

Trader Joe’s and Costco are limiting how many eggs shoppers can buy due to the avian influenza outbreak. “Due to ongoing issues with the supply of eggs, we are currently limiting egg purchases to one dozen per customer, per day, in all Trader Joe’s stores across the country,” a chain spokesperson told CNN.
