Is it okay to share popcorn? How gross is backwash? And am I spraying germs everywhere when I blow on my birthday cake? When it comes to food safety, there are at least as many misconceptions as there are actual facts.

With witty observations and illustrations throughout, this fascinating survey covers both good hygiene and lab-tested microbiology, and the duo lists their materials and methods (in case you want to replicate the experiments).
