Microplastics proliferating in the world’s oceans appear to also be carrying a host of bacteria, some so toxic that they can cause coral bleaching in tropical waters and even bring infections to humans with open wounds. Bacteria known to cause gastroenteritis were also found.
Researchers from the National University of Singapore sampled plastic debris in the waters around the city-state. They found that among the bacteria hitching rides on the microplastics were some useful organisms, such as those that can break down pollutants in the water.
But lead researcher Sandric Leong cautioned that since marine life are eating the plastic, the accompanying pathogens could be passing up the food chain.
