Kraft Foods Global, Inc. announced on Friday that it was voluntarily recalling three varieties of Velveeta Shells & Cheese Single Serve Microwaveable Cupswith limited “best when used by” dates because they could contain small pieces of thin wire bristle.

In a statement released from its headquarters in Northfield, Illinois, the world’s second-largest food company said they have received no complaints about the products and were issuing the recall “out of an abundance of caution”. They did not give details of how they discovered the products could be contaminated.

The affected products can be identified from their “best when used by” dates which are on the bottom of the package. A full list of the products affected is given in the table below.

About 137,000 cases of the products, which were manufactured in Champaign, Illinois and Lakeville, Minnesota, have been shipped to outlets across the US.

The products have not been distributed in Canada.

No other “best when used by” dates of Velveeta Shells & Cheese Single Serve Microwaveable Cups or any other Kraft Foods products are being recalled, said the company in a statement.
