Tyson Foods recalled about 190,000 pounds of frozen chicken fritters after three complaints from schools about hard plastic in the patties, the USDA says.

The products were sent to foodservice locations nationwide, not retail stores, Tyson Foods says in its recall announcement.

The 32.81-lb. cases of whole-grain patties labeled “golden crispy chicken chunk fritters” have four 8.2-lb. bags inside. The boxes, made at one plant on Feb. 28, have case code 0599NHL02 and establishment No. P-1325 in the USDA mark of inspection.

Consumers reported finding pieces of clear plastic and soft gray plastic in the chicken, according to the company. “Even though these reports are limited, out of an abundance of caution, the company is recalling 5,814 cases of product,” the announcement says.

Tyson and regulators had not received any reports of injury or illness at the time of the recall announcement.

Foodservice locations that bought the chicken should not serve it and throw it away or return it.

People with recall questions can call Tyson Foods Consumer Relations at 888-747-7611 from 8 a.m. to 5 p.m. CDT Monday through Friday.
