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.
The chocolate-covered blueberries were distributed nationwide through See's Candies Retail Shops, licensees and mail order.
The See family sold the company to Berkshire Hathaway in 1972.
