Highly Contagious, Antibiotic-Resistant Food Poisoning Establishes U.S. Presence

The kinds of bacteria that can cause food poisoning lurk all around us. These germs can be especially easy to pick up when traveling internationally as well as in places, such as children’s day cares, which are hard to keep clean. The infections usually clear up on their own but sometimes require hospitalizations and hefty doses of antibiotics to expunge. Unfortunately, the bacteria are becoming increasingly resistant to treatment. The latest bad news came in April when the U.S. Centers for Disease Control and Prevention reported an outbreak of Shigella sonnei that has become resistant to ciprofloxacin—one of the last remaining medications in pill form that can kill the germ. Since then a Scientific American investigation shows the worrisome strain is still circulating in the U.S. a year after it first emerged.
