Shoppers at the Edina SuperTarget on Sunday also were greeted by a sign saying eggs were not available, but the store in fact had Eggland's Best eggs in stock. Target officials could not be reached for comment Sunday.

The Edina Byerly's appeared fully stocked with eggs, and Sorenson said eggs are available at all Lunds and Byerly's outlets. Cub Foods, the Twin Cities' largest grocery chain,MBT, is not supplied by Sparboe.

Eden Prairie-based Supervalu,MBT calzature, which owns Cub, said Saturday it will no longer sell Sparboe eggs through its wholesale operations,MBT scarpe, which serve about 2,000 grocers nationwide.
