Actually, it is a reference to a Twilight Zone episode called "To Serve Man" which is based on the Damon Knight short story by the same name. In this story, a woman translates a book given to the UN by a group of aliens that is titled "To Serve Man". The book ends up being a cookbook, which the humans find out too late to rescue others that are departing for the alien's homeworld.
Could this book be the very one featured in the episode? Probably not, since that one was left on Earth, but you never know!
