WASHINGTON (AP) _ Concerned that people with dairy allergies might be harmed by its chicken fajitas, Tyson Foods Inc. is recalling 129,000 pounds of the product distributed nationwide.

The poultry company discovered that some of its fajitas contain the milk product whey, a known allergen, but the packaging does not list the ingredient, the Agriculture Department said Monday.

``Because of the potential hazard for people with milk allergies, we urge consumers to check their refrigerators and freezers,'' said Thomas J. Billy, an administrator with the USDA's food safety service. ``If they find the recalled products, consumers should not eat them and should return them to the point of purchase.''

The recalled products are Tyson's ``Restaurant Favorites Chicken Breast Fajitas'' and Kirkwood's ``Chicken Fajita Kit'' in 26.6-ounce packages. Both products have ``Est. P13137'' on the end of their labels.

The date numbers printed on the recalled Tyson kits begin with 265, 267, 268 and 270. On the Kirkwood product, the numbers begin with 273, 279 and 280.

While no illnesses have been reported, people allergic or sensitive to milk products might have a moderate to severe reaction if they eat the fajitas.

Tyson produced the kits at its Fayetteville, Ark., plant and distributed them nationwide.

The USDA advises anyone concerned about an illness or allergic reaction to contact a doctor immediately.

Consumers should return the products to store where they bought them. For more information, consumers can call USDA's meat and poultry hot line at 1-800-535-4555. The hot line is staffed from 10 a.m. to 4 p.m. EST Monday through Friday.
