All the Rugby World Cup countries marked Keep Rugby Clean day on Saturday.
The day recognises the program that has been implemented to educate players on making the right decisions when it comes to drugs and deterring the prevalence of doping.
Keep Rugby Clean is recognised by the World Anti-Doping Authority (WADA) as one of its more successful programs, having involved more than 13,000 players in the decade since its launch.
It is an education initiative to deter doping and with an aim of highlighting the responsibility that players and support staff have ensure they are looking after their health and competing cleanly.
More than 1000 out of competition tests have been conducted on competing World Cup teams this year alone.
Of 2,100 tests last year, just four returned positive tests and World Rugby has continued to up the ante with its testing program, increasing funding by 30 per cent.
Wallabies team physician, Dr Mike Cadogan, said while the number of positive tests was small, it was crucial for the sport to remain vigilant.
“As a sport, we need to make sure we continue to educate players about responsible decision-making ,” he said.
“It is important that everyone knows how to look after their bodies and how to make the right decisions in that regard.”
As part of a zero tolerance stance on drugs, all 2015 Rugby World Cup teams have undertaken mandatory anti-doping education in the lead up to the competition.
All teams and officials are being urged to don their Keep Rugby Clean T-shirts on Saturday as a reminder of their commitment to the program.
Italy were among those teams who observed the occasion, wearing pink T-Shirts to training ahead of their clash with Canada, that read “tackle doping”.
