Italian study finds antibiotic resistance genes in the world's oceans

According to a?research project led by Italy that analyzed?seawater samples worldwide, the presence of genes?linked to resistance to antibiotics is present in multiple 'ocean basins including remote waters.

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.

Researchers said that the results showed oceans as a global repository for pollution coming?from land. They also found genetic traces from antibiotic use and urban discharges far beyond their sources.

Researchers added that this could facilitate their spread to remote communities.

The study was presented Monday in Rome at a forum hosted by the National Health Institute of Italy (ISS) on ocean and human healthcare. It detected microplastics and traces containing?PFAS, "forever chemicals", and?SARS CoV-2 genetic material, even in remote areas and open ocean waters.

Andrea Piccioli, ISS Director-General, said that protecting human health today inevitably meant taking care of seas and oceans. She added that pollutants released in the environment are distributed globally via water, food, and climate systems.

SeA Care, an initiative led by Italy, links environmental health and human wellbeing. It brings together institutions such as ISS, 'the Italian Navy' and international research centers to create a global 'ocean monitoring /system.

The project collects samples using existing scientific and naval networks during routine missions. This reduces costs?and the environmental impact.

Over 140 sites in the Mediterranean, Atlantic and Pacific oceans, as well as the Arctic Ocean, were sampled during its first three-year period.

Scientists claim that the project shows how oceans are a good early warning system of global health risks. It supports policies to combat pollution, climate changes and emerging threats. (Reporting and editing by Crispian B. Balmer, Emilio Parodi)
