The use of antibiotics in factory farms in Asia is set to more than double in just over a decade, with potentially damaging effects on antibiotic resistance around the world. Factory farming of poultry in Asia is also increasing the threat of bird flu spreading beyond the region, with more deadly strains taking hold, according to a new report from a network of financial investors. Use of antibiotics in poultry and pig farms will increase by more than 120% in Asiaby 2030, based on current trends. Half of all antibiotics globally are now consumed in China alone. The Chinese meat and animal feed producers New Hope Group and Wen’s Group are now among the 10 biggest animal feed manufacturers in the world. The growth of Asian meat production in intensive units is also producing a rise in greenhouse gas emissions from the food chain, with emissions likely to rise by more than 360m tonnes, the equivalent of running 100 coal-fired power plants for a year. There are knock-on impacts such as deforestation, as China’s need for animal feed is responsible for more than a third of Brazil’s soybean production. The report, Factory Farming in Asia: Assessing Investment Risks, comes three years after a meat scandal in China, in which suppliers to McDonalds, KFC and others were found to be using dirty meat and products past their sell-by date. It also comes in the midst of a growing food scandal in Europe, which has required the recall of millions of eggs tainted with harmful chemicals, and as concerns have been aired over the impact of Brexit on imports of farm products to the UK.
