Tyson has recalled nearly 2.5 million pounds of ready-to-eat breaded chicken due to undeclared allergens.
The U.S. Department of Agriculture's Food Safety and Inspection Service announced that the products could contain milk, a known allergen, which is not listed on the label.
The recall is limited to foodservice customers, and affected products are not available for purchase in retail stores.
Tyson was made aware of the problem on Tuesday, when they were alerted by an ingredient supplier that the bread crumbs they used to make the chicken contained milk.
According to Tyson, some schools purchased these items, but there have been no confirmed reports of allergy reactions.
Anyone concerned about an injury or illness should contact a healthcare provider.
