The overuse of antibiotics not just for human and animal health but also in food production is leading to an increased resistance of bacteria, fungi, viruses and parasites to antimicrobial treatments, according to the Food and Agriculture Organization (FAO).

Low and middle-income countries have been affected most by what experts have called “superbugs.”

Charlotte Lomas has been speaking to FAO’s Christine Czerniak and began by asking for a definition of antimicrobial resistance or AMR.
