A Florida bakery has filed a federal lawsuit in Minneapolis alleging a price-fixing conspiracy involving several Minnesota producers of processed eggs.

ZaZa Inc., a Miami corporation that uses the trade name Silvery Tray Cookies, filed the suit Wednesday against Golden Oval Eggs of Renville, Minn., Michael Foods Inc. of Minnetonka, and MoArk, a unit of Land O'Lakes Inc., Arden Hills.

All three companies have confirmed in public filings or statements that the Department of Justice is investigating price-fixing allegations against them. The companies have said they are cooperating with the government.

The lawsuit was filed on behalf of ZaZa by Lockridge Grindal Nauen of Minneapolis, Kaplan Fox & Kilsheimer of New York City, and Criden & Love of South Miami, Fla.

ZaZa is seeking court approval for class-action status, meaning it could represent other customers of the companies.
