Tyson Foods has voluntarily recalled 51,360 pounds of uncooked, foodservice chicken due to an undeclared soy-based allergen. 

The affected products, which were sold to foodservice companies that typically supply restaurants, covers 29 US states.

Arkansas-based Tyson said it has not had any reported illnesses but initiated the recall as a precautionary measure.

Tyson had been in the process of reducing the number of allergens in the company's foodservice products and produced some products with the old formulation while prematurely using a new label. 

The products were produced at the company's Vicksburg, Mississippi, location between 23 July and 5 August 2008.

The recalls include ten-pound cases of Standard Quality Uncooked Fritters; Old Fashioned Chicken Breast Tenderloins; ten-pound cases of Sysco Uncooked, Fritters; Chicken Breast Tenderloins; ten-pound cases of Heritage Valley Uncooked Steakhouse Chicken Breast Tenderloin Fritters; 20-pound cases of Spare Time Uncooked Fritters; Chicken Breast Tenderloins; and ten-pound cases of Tyson Uncooked Chicken Breast Tenderloin Fritters.
