Canadians who enjoy the occasional bake-at-home Delissio Pizza may want to reconsider their next bite, as two batches of the company’s frozen pizza are being recalled due to possible glass contamination.

An announcement on Nestlé Canada’s website says the source of the glass may be from the spinach used, which is a common ingredient in the two types of Delissio frozen pizzas.

Nestlé Canada is “voluntarily” recalling the affected products, which include one batch of “Vintage Tuscan Style Chicken” pizza and one batch of “Thin Crispy Crust Grilled Chicken Tomato and Spinach” pizza, both under the Delissio brand name.

The Tuscan-style chicken pizza has batch code 6017525952 and a best before date of November 12, 2016, and the thin-crust pizza has batch code 53625273C1 and a best-before date of July 25, 2016.

Nestlé Canada says it has alerted the Canadian Food Inspection Agency and the customers who have received those batch codes so that they can remove the products from store shelves immediately.

While there have been no consumer complaints in Canada, the company is proceeding with the recall due to a “small number” of consumer complaints in the United States, none of which involved injury.

In 2013, customers were warned not to consume the thin-crust pizza mentioned above as it may of contained pieces of plastic.
