Phage Against the Machine

If you thought food poisoning was just a matter of the occasional stomach upset from a dodgy shrimp or two, the CDC has some unsettling numbers for you: foodborne bacteria is responsible for at least 48 million cases of illness, more than 130,000 hospitalizations, and 3,000 deaths a year in the U.S. alone. And those numbers aren't going down. But wait: a new fighter has entered the ring! Say hello to the bacteriophage, a small-but-mighty bacteria-busting virus that can wipe out entire colonies of harmful pathogens—and that is starting to be sprayed on packages of cold cuts near you.
