Superbug found in Rio Olympic waters

Researchers in Brazil have discovered drug-resistant bacteria in the sea waters where sailing and windsurfing events will be held during the 2016 Olympics in Rio de Janeiro.

The “super-bacteria” are usually found in hospital waste and produce an enzyme, KPC, resistant to antibiotics.

Researchers found the bacteria in samples taken from Flamengo beach.

Nearly 70% of sewage in Rio - a city of some 10 million people - is spilled raw into the waters of Guanabara Bay.

The bacteria were found in samples taken from several locations along the Carioca river.
