A banana was thrown at Samba during a match against Lokomotiv Moscow in March, but he insists that a small number of fans will not bring him down.
"I feel extremely passionately about racism in football and will never let the small community of racists break me," Samba said in a statement to the Associated Press.
"I'm a strong character and will keep fighting for my team.
"I am thoroughly enjoying my time in Russia and although I was of course angry at the incident, along with the rest of the football world, racist issues here are no different to what I have experienced in other countries."
This is not the first time Russian fans have been accused of racist behaviour. Samba's team-mate Roberto Carlos had bananas thrown at him twice last year and in 2010, Lokomotiv Moscow fans unfurled a banner showing a banana directed at Nigerian striker Peter Odemwingie.
