Shampoo in the water supply triggers growth of deadly drug-resistant bugs
“Fabric softeners, disinfectants, shampoos and other household products are spreading drug-resistant bacteria around Britain, scientists have warned. Detergents used in factories and mills are also increasing the odds that some medicines will no longer be able to combat dangerous diseases.
In their study, the scientists looked at quaternary ammonium compounds (QACs) that are used in many household cleaning goods. Every day, huge volumes of these chemicals are flushed from homes and factories into sewers and rivers. In high concentrations, QACs kill bacteria. However, in sewage, these chemicals become diluted and bacteria have evolved resistance to them.
“The inference is clear,” added Gaze. “We are producing sewage and river water that have more and more drug-resistant bacteria in them and that these are now poised to enter the food chain.”
Wellington added: “Once they are in the land, these bacteria will get into the bodies of agricultural workers or people who use the land recreationally and will form reservoirs of drug-resistant microbes that could pose all sorts of problems. This is going to need a great deal of monitoring.”“
