The threat of ‘superbugs’ and infections that can’t be treated“Every time we think we’ve gotten ahead of the bugs, they come back stronger and fitter,” said Ramanan Laxminarayan, director the Center for Disease Dynamics, Economics & Policy (CDDEP). It is the ability to mutate that has given rise to “superbugs” that resist some—or, increasingly, all—the antibiotics that were hailed as miracle drugs in the last century, creating one of the biggest threats to global health, food security, and development today, according to the World Health Organization. For years, experts have warned against the overuse of antibiotics in livestock and fish farming, which stave off infections in animals in crowded living condition and also help animals gain weight faster, making them ready for slaughter sooner.
