Tyson Foods has recalled 75,320 pounds of frozen chicken nuggets sold at Sam’s Club warehouse stores after some consumers complained of finding bits of plastic in their food, the company said Friday.

The voluntary recall includes 5-pound bags of Tyson white meat frozen chicken nuggets that were sold at Walmart-owned Sam’s Club locations nationwide.

According to the firm, based in Springdale, Ark., complaints were received by “a small number of customers.” The U.S. Department of Agriculture said the complaints were valid, and that the problem was traced to a product scraper inside the blending machines. Company officials said the affected product was produced on two days, on Jan. 16 and Feb. 26, on a single line at one of the company’s 40 chicken production plants.

According to the USDA, the recall also includes 40 cases a product called “Spare Time Fully Cooked Nugget-Shaped Chicken Breast Pattie Fritters w/Rib Meat,” which is sold in 20-pound bulk packages for institutional use in Indiana and Arkansas. The recalled cases of this product were sold to a single institutional customer.  Those bulk packs have identifying case codes of “0264SDL0315 through 19” and “0474SDL0311 through 14.”

Tyson received complaints of “minor oral injury” associated with the nuggets, and the USDA said that anyone worried about injury or illness should consult a healthcare provider.

The USDA classified the recall as a Class II incident, which means that it is “a health hazard situation where there is a remote probability of adverse health consequences from the use of the product.”

In February, nearly nine million pounds of meat were recalled from Rancho Feeding Corporation, and included meat used in the company’s “Philly Steak” and “Croissant Crust Steak and Cheese” sandwiches.  The USDA classified that recall as a Class I incident, which is defined as “a health hazard situation where there is a reasonable probability that the use of the product will cause serious, adverse health consequences or death.”

The 5-pound Tyson Foods chicken nuggets bags have manufacturer codes of “0264SDL0315 through 19” and “0474SDL0311 through 14.” The establishment number “P-13556” can also be found on the bags.

If a consumer has a bag of affected product, they should discard the product, cut the UPC and date code from the back of the bag and mail it to the following address for a full refund:
