On May 2, 2013 Nestlé Announces Voluntary Recall of four Select Varieties of California Pizza Kitchen and DiGiorno Frozen Pizzas.  For more information and the specific codes for the recall visit Nestles USA

The voluntary recall is limited to frozen pizzas with these specific production codes, which were distributed nationwide. No other production codes/dates, sizes or varieties of CALIFORNIA PIZZA KITCHEN or DIGIORNO pizzas are affected by this recall. The reason for the recall is that the pizza may contain fragments of clear plastic. Nestlé USA is taking this action after a small number of consumers reported that they had found small fragments of plastic on the CPK Crispy Thin Crust White pizza. Our investigation indicates this is directly related to a particular lot of spinach we received from one of our suppliers. Although no complaints have been received to date on the other three varieties that used this spinach, we are recalling these additional varieties in an abundance of caution.
