Saha was speaking at a special conference at Old Trafford being held by Manchester United Foundation and Trafford's Children and Young People's service to address issues surrounding racism and bullying.
In front of more than 200 schoolchildren, Saha signed the Trafford Anti-Bullying Charter to reinforce the message that preventing bullying is the responsibility of every community member.
While the Kick It Out campaign has worked tirelessly to eradicate racism in England over the past decade, Saha recognises other European countries have not been so pro-active.
Asked whether racism was still prevalent in football today, the France international replied: "You will see it on Wednesday, I think.
"We are travelling to Italy, and in those kind of places it seems like they are used to it. They don't fight it like we have done in England.
"They are starting to recognise it and think about it, but not very strongly - whereas England is a good example of where it has been tackled.
"I have to think about the future of my children as well - and since having two children of mixed colour, I've become more passionate about this.
"Everyone has to understand it is a bad thing, that they shouldn't get used to it or turn their back. That's not the way to fight it.
"You have to be strong and stand up.
"Everybody has to understand it is not acceptable any more."
