The latest report about the safety of the water in Rio de Janeiro -- both at Olympic venues and popular tourist beaches -- won't do much to ease health fears among athletes and fans.

Two as-yet unpublished academic studies have found drug-resistant "super bacteria" present in beaches that are set to host swimming events and in a lagoon slated to host rowing and canoe events, according to Reuters, which reports that it has seen the studies.

The first study it cites is said to have found the dangerous microbes at Copacabana, Ipanema, Leblon, Botafogo and Flamengo Beaches.

The description given for the dangers of the "super bacteria" from Reuters:

The second study, due to be released next month, details similar findings in the Rodrigo de Freitas lagoon.

How did it get there? Back to the report:

Both studies -- and a previous study that found similar results in Guanabara Bay -- used water samples from 2013 and 2014, but experts quoted in the report say there's scant evidence the problem has been addressed and is likely worse due to the nature of how the microbes spread.

The Opening Ceremony is set for Aug. 5 -- less than two months from today.
