Two-time cross-country world champion Emily Chebet has been banned for four years after testing positive for a banned substance.
Chebet, the cross-country world champion in 2010 and 2013, was one of seven Kenyans suspended by Kenya Athletics on Friday for using performance enhancing drugs.
The Kenyan Athletics Federation confirmed the 29-year-old will be suspended until July 2019 after testing positive for the diuretic and masking agent furosemide.
Kenya's 400m hurdles champion Koki Manunga and 400m runner Joyce Zakary, who were provisionally suspended at the World Championships in Beijing in August for doping, also received four-year bans for furosemide.
The other four athletes banned on Friday were Agnes Jepkosgei, Bernard Mwendia, Judy Jesire Kimuge and Lilian Moraa Marita.
Jepkosgei was banned for four years for testing positive for the anabolic steroid metabolite norandrosterone.
Mwendia was given a two-year ban for norandrosterone. Kimuge was banned two years for the norandrolone and Marita two years for the blood-booster EPO.
There has been a recent spike in doping cases in Kenya and more than 40 athletes have now failed tests since 2012.
