ROME, June 8 (Reuters) - Genes linked to antibiotic resistance are present across multiple ocean basins, including remote waters, according to findings released on Monday from an Italian-led research project that analysed seawater samples worldwide.
The SeA Care project found antibiotic-resistance genes in the Mediterranean, Atlantic, Arctic and other regions, with higher concentrations detected near busy shipping routes and densely populated coastal areas.
The study, presented on Monday at a forum on ocean and human health in Rome hosted by Italy's National Health Institute (ISS), also detected microplastics, PFAS "forever chemicals" and traces of SARS‑CoV‑2 genetic material even in open ocean waters and remote regions.
"Protecting human health today inevitably means taking care of the seas and oceans," ISS Director General Andrea Piccioli said, adding that pollutants released into the environment are redistributed globally through water, food and climate systems.
