Kraft is recalling 242,000 cases of the Original flavor of Macaroni & Cheese Dinner because of concerns that some boxes could contain small pieces of metal.

"We believe a piece of stainless steel got wedged in a metal piece of equipment, which may have generated friction that resulted in small pieces of metal potentially falling into the product", said Kraft spokeswoman Joyce Hodel in a statement.

Kraft distributed the product across the US and to Caribbean and South American countries but not to Canada. According to Hodel, eight complaints of metal pieces have been received by the company and no injuries have been reported so far.

In the meantime, Trader's Joe also recalls its raw walnuts because some of it might be contaminated with Salmonella. The US Food and Drug Administration (FDA) said that Trader Joe's affected products involve certain lots of Raw California Walnut Pieces, Raw California Walnut Baking Pieces, Raw California Walnut Halves & Pieces and Raw California Premium Walnut Halves.

According to experts, Salmonella is a food-borne bacterium. This bacterium causes more than one million illnesses in the US and 450 deaths every year. The Centers for Disease Control and Prevention (CDC) said that infected people develop diarrhea, fever and abdominal cramps. According to CDC, children and those with weakened immune systems are at risk.

Trader Joe's affected products are available in 16-ounce packages with December 2015 best-by dates. According to the FDA, an announcement has been made about the recall after routine testing by an FDA contractor found salmonella in certain packages of raw Trader Joe's walnuts. So far, no reports of illnesses have been there related to the recalled products.
