Certain chocolate products are being recalled from stores nationwide due to undeclared milk allergens that may cause life-threatening reactions for people who are allergic.

Weaver Nut Company, Inc. issued the recalled for certain semi-sweet nonpareil chocolates that were distributed to retail and grocery stores throughout the nation.

“People who have an allergy or severe sensitivity to milk run the risk of serious or life-threatening allergic reactions if they consume the impacted products and Lot’s listed below,” the company said in announcement published Wednesday by the Food and Drug Administration.

The potentially affected chocolates include the following lot numbers:

• Semi-sweet nonpareil chocolates with Christmas seeds

204206, 204207, 204208, 204209, 204212, 224225

• Semi-sweet nonpareil chocolates with white seeds

204214-RL, 204214, 204215, 224221, 224222, 224223, 135215, 135216, 135217, 135220, 135221, 145204, 145205-1, 145207-1, 145210-1

The company said no illnesses had been reported to date. But anyone who has a milk allergy is urged not to eat the chocolates. Those customers should throw the product away or return it to the store for a refund.

Milk is one of the top nine allergens that the FDA requires companies to declare, according to Newsweek.

“The issue was discovered through a wholesale customer complaint upon receipt of shipment misaligned with updated product (specification) followed by a lab test to confirm the milk presence,” Weaver Nut Company said in a release.
