SINGAPORE - Ikea Singapore has issued a warning that milk and hazelnuts are ingredients in two dark chocolate products, but they are not listed on the packaging.

Ikea said that for dark chocolate Choklad Mork 60% and Choklad Mork 70%, "the presence of milk and hazelnut is insufficiently declared on the product packaging".

"Persons allergic to milk or hazelnuts may experience an allergic reaction if eating the product", the furniture chain said in a statement on Monday (June 27).

The products have been recalled, said Ikea but it added that the products are safe to eat for consumers not allergic to milk or hazelnuts.

Customers can return the affected products at the nearest Ikea store at a full refund, it added.
