The candy company owned by Berkshire Hathaway that Warren Buffett once called "the prototype of a dream business" is recalling one of its sweets.

San Francisco-based See's Candies is recalling all its Dark Chocolate Blueberries because the product contains undeclared milk, the company said in a press release that was posted on the Food and Drug Administration website.

The recall was initiated after a customer reported having an allergic reaction to the product, the statement said.

People who have an allergy or severe sensitivity to milk run the risk of serious or life-threatening allergic reaction if they consume it.
