Reuters) – A week after grilling hamburgers in his backyard in November 2011, business consultant Kenneth Koehler became violently ill. He suffered stomach pains, diarrhea and nausea – and rushed to the hospital emergency room in Biddeford, Maine.
Days later, his doctors told him that his burger was contaminated with Salmonella Typhimurium, a strain commonly found in ground beef.
But Koehler’s salmonella was more dangerous than he realized. Records provided to Reuters by Koehler showed that the salmonella strain in the ground beef was resistant to nine types of antibiotics. Three of the antibiotics that didn’t work were cephalosporins, including ceftriaxone, according to the U.S. Centers for Disease Control and Prevention records.
