Just When You Thought....Now It's Frozen Pizzas

Ugh to frozen pizzas anyway. But--apparently General Mills' Totino and Jeno's frozen pepperoni pies may contain a strain of E. coli, so the company is recalling a gazillion of them.

According to Environment News Service, "The recall affects 414,000 cases of pizza products Totino's and Jeno's now in stores and all similar pizza products in consumers' freezers. Consumers are advised to discard the products. "

Is microwaving to blame for not killing off naughty bacteria? I heard one talking head on the news suggest that, with no real scientific backup. Could baking a frozen pizza in a proper oven kill off the stuff?  Maybe, at 450 degrees?
