Heavy metals and other toxins frequently contaminate food and water. The culprits read like a litany of bad actors—lead, cadmium, mercury, arsenic, chromium—but their numbers run into the thousands. Microbes have long been enlisted for bioremediation, but they also have the potential to protect us from toxins, according to a minireview in the September Applied and Environmental Microbiology. "Beneficial bacteria are indeed capable of degrading pesticides and sequestering toxic chemicals," says coauthor Gregor Reid of the Lawson Health Research Institute, London, Ontario.
