ISSUE FOCUS FEED & ADDITIVE MAGAZINE January 2023 43 Fast-forward nearly 80 years and AMR is one of the biggest threats in global health, food security and development today, according to World Health Organization (WHO). In 2019, almost 1.3 million deaths directly resulted from illnesses caused by drug-resistant bugs, according to a report released by the Lancet, a medical journal, on January 20, 2022. The large-scale use of antibiotics could lead to the death of up to 10 million people by 2050, meaning that one life will be taken every three seconds. In other words, superbugs could be a bigger killer than cancer, as projected in the chart (on the right). These alarming statistics reveal an urgent need for sweeping global changes to tackle antibiotic resistance on every front, from the healthcare industry to the agriculture sector. POLICIES TO PREVENT ANTIBIOTIC RESISTANCE FROM AGRICULTURE Farmers began putting antibiotics in chicken feed in the 1950s after observing lower mortalities and faster body weight gain associated with their use. While the 1950s and the 1960s were the golden era of antibiotic discoveries, progress slowed down in the following decades, and new antibiotics are not currently being discovered. Meanwhile, bugs have evolved to resist many of the antibiotics available to both humans and animals. Consequently, regulatory boards have become stricter about antibiotics in animal feed. Currently, the main uses of antibiotics in poultry productions are to treat disease, prevent disease or promote growth. The first use must exclude medically important antibiotics for humans in many countries now. The second and third uses are being increasingly restricted, as shown in the timeline below.
