Aldi is recalling its Rooster’s Southern Fried Poppin’ Chicken from its stores in the U.K. because they may contain small pieces of hard plastic that could pose a safety risk, the U.K. Food Standards Agency (FSA) announced.

The affected products were in 210-gram packages and contain the “best before” date of September 4, 2019. The product labels also contain the lot number 10101701 and the product code numbers 45004 and 75744.

According to FSA, point of sale notices will be displayed in all retail stores that are selling the product. These notices explain to the customers why the products are being recalled and say what to do if you have purchased them.

All customers who have purchased the products are being encouraged to return them to the Aldi store where they were bought.
