Microplastics in wastewater protect harmful bacteria from treatment, study finds

A new study reveals that microplastics in wastewater can protect harmful bacteria from treatment processes, potentially posing risks to human health. These microplastics can harbor pathogens like Listeria and E. coli, which may survive wastewater treatment. Researchers found that microplastics create a "plastisphere," a biofilm that can shield bacteria from being eliminated. This raises concerns about the effectiveness of wastewater treatment and the potential for pathogens to enter the food chain. The study also highlights the risk of antibiotic resistance genes being transferred through these biofilms. Researchers emphasize the need for more studies to address the challenges posed by microplastics in wastewater.
