Revealed: The secret ingredient to defeating River Seine health problems after Olympic Games men's triathlon was postponed due to pollution concerns

Moesha Johnson has revealed why a simple can of Coca-Cola is alleviating her of any health concerns to plunge into the dirty River Seine.

On Tuesday, the men's triathlon was postponed because of concerns over water quality in the river following a $1.5 billion cleaning effort.

It remains unclear whether athletes will agree to swim in the river given the numerous health concerns in the build up, but Australia's Johnson has revealed a trick she has up her sleeve to fend off any issues.

'The urban myth of Coca-Cola is true, we will often have a Coca-Cola afterwards to try and flush out anything inside of us,' she said.

'I use it professionally.

'I just do what I'm told by the medical professionals around me.'

In that vein, Johnson says she will listen to experts around her as to whether it is safe to swim the 10km route in the River Seine next week. 

She added that she is also monitoring the face pace of the river's current. 

'We've prepared for it and I'm sure the people out there running the show will make a decision that's appropriate for the athletes,' she said.

Swimming training for the triathletes was canceled on Sunday and Monday and the decision has been taken to move the men's race from 8am local time Tuesday to Wednesday at 10:45am. The women's race will remain as scheduled: Wednesday at 8am. 

A statement from World Triathlon said Friday remains a contingency day if one or both of the races are unable to go ahead: 'Tests carried out in the Seine today revealed water quality did not provide sufficient guarantees to allow the event to be held. Despite the improvement in the water quality levels, the readings at some points of the swim course are still above the acceptable limits.'

Exacerbating the issue are weather forecasts that call for rain showers and even some storms between Tuesday night and Thursday. Rain typically raises bacteria levels in the Seine, where June tests revealed unsafe levels of E. coli - a potential sign of fecal matter and disease-carrying germs. 

According to World Triathlon Federation standards, E. coli levels beyond 900 colony-forming units per 100 milliliters is considered unsafe.
