Do you have any boxes of Walmart house brand Black Angus beef burgers with Vidalia onions lurking in your freezer? If so, time to check labels: almost 90,000 pounds of that specific burger type (about 44,784 boxes) has been recalled because there may be “extraneous wood materials” in the meat.

While the U.S. Department of Agriculture recall notice simply says that the burgers were distributed “to retail stores nationwide,” Sam’s Choice is a Walmart exclusive brand, which of course refers to late Walmart founder and mega-mart patriarch Sam Walton.

No consumers have reported finding pieces of wood in their burgers to the USDA yet. The company that packaged the patties, Huisken Meat Company in Minnesota, found the wooden contaminant during production, and has recalled all burgers made between November 19 and December 5.

What should consumers look for when checking their freezers? Here’s what the box will look like (yes, we edited the version that you see at the top of this page):

Recalled boxes will have use-by dates of 5/17/2016, 5/29/2016, and 6/6/2016. For reference, the USDA inspection site number is 394A.

Customers should bring the products back to the store for a refund or throw them away. If you have any questions about products in your home or about the recall in general, call the Huisken Meat Company’s customer service manager at (618) 857-4011.
