It's described as a silent pandemic with risks akin to climate change, and it's bad news for food supplies. Antimicrobial resistance, where viruses, fungi or bacteria become resistant to medicines, kills more than 1 million people every year and is a drag on healthcare resources and economies. But the problem, known as AMR, also affects farm animals including cattle and poultry. If unaddressed, superbugs could result in livestock output losses equal to the consumption needs of 746 million people by mid-century, research released this week showed. Some 2 billion people could be affected in a more severe scenario, according to modelling based on data from more than 200 countries. "The impact of AMR on the health of animals, our environment and our economy cannot be overlooked," said Emmanuelle Soubeyran, director general of the World Organisation for Animal Health, which led the study. The threat of drug-resistant infections to human health is already widely recognized. More than 39 million people could die globally from antibiotic-resistant infections over the next 25 years, a recent study in The Lancet showed. But the use of antibiotics in livestock is also part of the problem. In the US alone, about 80% of antibiotics sold go into food that animals eat. "Companies — from pharma to pork producers — take advantage of lax regulations allowing the routine use of antibiotics in animals," said Jeremy Coller, founder of the FAIRR investor network. That enables "them to cut corners in animal welfare, while diminishing antibiotic effectiveness in humans," he said. FAIRR is part of an initiative of investors with more than $13 trillion in combined assets who recently warned that AMR is now a "systemic risk akin to climate change and nature loss." World health leaders who convened in New York this week committed to reducing human deaths linked to AMR by 10% by the end of the decade. The food-security impact will probably be felt more acutely in low- and middle-income countries, the researchers including WOAH said. They called for investments in new drug innovations and healthcare improvements, which would return $28 for every $1 invested.
