The recall affects 242,000 cases of Kraft Macaroni & Cheese Dinner that have been distributed throughout the United States, Puerto Rico, the Caribbean and some South American nations. The Associated Press reported that it amounts to about 6.5 million boxes of Kraft Macaroni & Cheese Dinner, one of the Kraft Foods Group's signature brands.
Consumers are warned not to prepare and eat macaroni that comes in the original flavor, 7.25-ounce sized box sizes carrying a "best when used by" date between Sept. 18 to Oct. 11 and a code "C2" below the expiration dates. The code shows the specific factory line where the potentially tainted boxes were produced.
Some of the dinners also come in packs containing multiple boxes made at different facilities. Consumers should check the individual boxes, and return potentially tainted boxes to stores for an exchange or refund, according to Kraft.
The Food and Drug Administration has posted the recall alert on its website. "The agency has been working with the company as it gathers additional information concerning the scope of the recall," a spokeswoman said.

In August 2014, Kraft voluntarily recalled more than 7,000 cases of its American Singles cheese slices after a supplier didn't properly store an ingredient. And in September 2011, Reuters noted, Kraft recalled more than 135,000 cases of single-serve Velveeta Shells & Cheese because of wire bristle pieces in some packages.
Kraft, which launched its iconic macaroni and cheese product in 1937, has dominated the market for decades. Recently, smaller companies have begun competing with mac and cheese made with more natural ingredients. Still, Kraft has said it generates more than $500 million in annual sales of macaroni and cheese products, Reuters has reported.
In the wake of the recall announcement, some consumers are posting their concerns on Kraft's Facebook page:
