Tempers were running high at the end of Saturday`s 2-2 draw, as both teams had players sent off for innocuous incidents.
Boateng claims he was talking to Lee Bowyer about the incident that led to Franck Queudrue seeing red when Barmby came over, barged into him and launched a torrent of verbal abuse.
The Dutchman never publicly mentioned racist abuse had been aimed at him, but the media construed his claim of 'offensive remarks' as being racist.
Barmby has now reacted angrily to suggestions that he racially abused Boateng.
Speaking at a press conference at Leeds` Thorp Arch training ground on Monday, Barmby said: "I'm devastated by what I've seen and read in the papers today.
"Words were exchanged between me and George Boateng on Saturday, but that's what goes on on a football pitch.
"I'm devastated by this for me, my family and everyone who knows me as they all know that I haven't a racist bone in my body.
"I don't know where he's coming from and I think it's disgusting that I'm here now seemingly on trial to defend myself, when a guy turns round and does what you all saw he did on Saturday.
"If I racially abused a bloke surely I should be the one apologising not the other way round.
"I was prepared to let the whole thing go but after reading the papers today I can't, and I have to respond. I'm devastated and disgusted by the whole thing.
"I have white friends, black friends and I just cannot accept why I have to be here defending myself."
Boateng is alleged to have spat in the direction of Barmby and Jonathan Woodgate, something he denies, and the Leeds player is still clearly angry about that incident.
He added: "It looks like he's trying to find a get-out clause for his actions. You saw what he did."
Barmby received support from his Elland Road boss Terry Venables.
He said: "This has come like a bolt out of the blue. I've known Nicky a long time and there's no way he should be sitting here defending himself. He is in an awful position.
"There were a few things that went on after the game and I asked him about his face, but we were prepared to let it go.
"We were offered an apology by Boateng on Saturday but I said I would only accept a public apology as it was done in public.
"We thought that was it. But now this at a time when we are trying to sort this sort of thing out in football.
"It's a dangerous precedent and I think the questions and answers should now come from the other side."
Barmby was sporting a large scratch across his cheek on Monday, and he claims that was the result of a clash with Boateng in the tunnel after the game.
The former Liverpool man added: "In the players' tunnel as we left the field I was scratched across the face by Boateng.
"George has also gone on record to say we shook hands, that he apologised to me personally after the game and that we met in the players' lounge.
"These claims are also untrue. He didn't personally apologise to me afterwards, and I didn't even go in the players' lounge."
It would seem that this saga still has some distance to run at a time when racism in football is in the spotlight.
