Halloween chocolate “eyeballs” sold at discount retailers are being recalled because the candy may contain an undeclared milk allergen, according to the U.S. Food and Drug Administration (FDA). The recall affects products sold at TJ Maxx, Marshalls, HomeGoods, and Sierra Trading Post. No illnesses have been reported at the time of the notices.

Quartz and Newsweek both report that the issue is specifically related to allergic reaction risk for people who have milk allergies. The FDA warns that the chocolates may include milk ingredients that are not listed on the packaging, which could lead to reactions among sensitive consumers. Newsweek also notes that the recall covers multiple states, presenting the scope as affecting 13 states, while other outlets focus on where the items were sold and the allergen concern.

In both accounts, retailers and the FDA advise consumers to check recall information and avoid consuming the product if it includes milk allergen concerns.
