Nestle (NESTLE-S-A) announced in a press release that it is voluntarily recalling some DiGiorno pizzas, Lean Cuisines, and Stouffer’s meals that may contain foreign matter. Nestle was alerted to the issue when numerous consumers issued complaints with the company after having found small pieces of glass in some of these products. Luckily, no injuries have been reported.

The recall affects four varieties of DiGiorno, five varieties of Lean Cuisine, and three varieties of Stouffer’s. It only covers certain products with specific production codes, which are listed on Nestle’s website and can be found on the side panel of the package.

Investigations have not yet concluded, but Nestle stated in the press release that the offending ingredient is most likely spinach, which is a common denominator among each one of the affected items. The company urges customers who have purchased the products not to consumer them.

According to a Nestle spokesperson, the recall affects about 330,000 cases of the products, with each case containing between six and nine units, that had been shipped to stores nationwide.
