Study Finds Antibiotic-Resistant “Superbugs” in Dog Foods, Representing International Public Health Risk

Scientists at the University of Porto found that more than half of the different types of dog food samples they tested contained Enterococci bacteria. More than 20% of the isolates were resistant to linezolid, a “last-resort” antibiotic that is used when all other treatment options have failed, and some of the multidrug-resistant bacteria in raw dog food were identical to those found in hospital patients in different European countries.
