Cuisinart's blade: eight million processors that shed metal into food

For nearly two decades Cuisinart sold food processors whose blades were held together by four rivets. The riveted blade could crack over time, and small metal pieces of it could break off into the food being processed.

Conair, the owner of the Cuisinart brand, received 69 reports of consumers finding broken blade pieces in their food, including 30 reports of mouth lacerations or tooth injuries. The 22 affected models had been sold from July 1996 through December 2015 for between $100 and $350.

The recall covered about 8 million units in the US and a further 300,000 in Canada. The blade design had been in use for decades before the defective batch was caught, which is why the recall swelled to eight million machines.
