Kraft Heinz announced Thursday that it is expanding its voluntary recall of Kraft Singles products due to a choking hazard caused by a manufacturing error with the film packaging around individual slices.

The company first announced a recall on July 31 of 3- and 4-pound packages of the American and White American pasteurized prepared cheese products with “Best When Used By” dates between Dec. 19, 2015 and Jan. 4, 2016. However, the new recall expanded it to include 1-pound packages and packages with “Best By” dates between Dec. 12 and March 2, 2016.

According to The Associated Press, the recall affects 335,000 cases. The packaging error results in film sticking to the slices even after taking the wrapper off.

In July, Kraft said it received three complaints about consumers choking, but it said this week that it has received two more reports. It also said there were seven other complains about the packaging.

The original recall only covered products sold in the U.S., Puerto Rico and Grand Cayman. But the expansion also includes products sold in Anguilla, the Bahamas, Belize, Bermuda, Netherlands Antilles, St. Kitts and Nevis, South Korea, St. Lucia and the British Virgin Islands.

Consumers with recalled products should take them to the store where they were purchased for a refund.
