Tyson Foods says it is recalling 39,000 pounds of Weaver brand frozen chicken patties that may be contaminated with extraneous materials.

The U.S. Department of Agriculture’s Food Safety and Inspection Service announced the recall for frozen, fully cooked chicken items that were produced on Jan. 31, 2019.

The following products are subject to recall:

26-oz. resealable plastic bags containing “Weaver CHICKEN BREAST PATTIES BREADED CHICKEN BREAST PATTIES WITH RIB MEAT” with a best if used by date of “Jan312020” and lot code 0319PBF0617, 0319PBF0618, 0319PBF0619, 0319PBF0620, 0319PBF0621, 0319PBF0622, 0319PBF0623, or 0319PBF0600 represented on the label.

The products subject to recall bear establishment number “P-13456” printed on the back of the resealable plastic bag.

The items were shipped to retail locations nationwide.

The problem was discovered after the recalling firm notified FSIS of consumer complaints.

However, neither the U.S. Department of Agriculture’s Food Safety and Inspection Service or Tyson disclosed what “extraneous materials” were found in the chicken.

Anyone concerned about an injury or illness should contact a health care provider.
