AUSTIN, Texas -- Whole Foods Markets is recalling vegan pumpkin pies produced and sold in its Southwest region because they contained undeclared walnuts.

The nuts would pose a risk to those who have nut allergies or severe sensitivities.

In a statement Wednesday, the Austin-based grocery chain says the pies were sold as half and full pies packaged in clear clamshell packages and brown paper boxes. They bear the UPCs 24917100000 and 24917300000 with sell-by dates of Oct. 27-Nov. 30.

The recall affects pies sold in stores in Texas, Oklahoma, Louisiana and Arkansas.

"To date, no serious illnesses have been reported from the consumption of this product, which has since been removed from store shelves," Whole Foods told CBS News in a written statement sent Wednesday evening.
