The firm became aware of the problem after a consumer reported finding a Snickers piece in the Dove product but no allergic reactions have been reported to date.
Mars Chocolate North America said the seasonal item is sold at Walmart stores across the US. The firm added it was working with the retailer to ensure the recalled product is removed from sale.
It may contain some Snickers, Milky Way and Twix pieces that contain peanuts, wheat and/or eggs, but these ingredients are not listed on the outer package ingredient label.
People who have allergies to peanuts, wheat and/or eggs risk serious or life-threatening allergic reaction if they eat the products.
This item was shipped and distributed to Walmart and sold at retail food stores starting September 19 through December 1.
If consumers believe they have purchased this item and have allergy concerns, they should return it to the store where they purchased it for a full refund, added the company.
Item number 10139802 and UPC 400050521 with lot codes 537CG4PA30, 537DG4PA30, 538AG4PA30, 538AM4PA30, 541AG4PA20 and 542EM4PA20 are affected. See a list of affected locations here.
