Jeremy Hunt said the comments made by William Henwood, who is standing in a council election, were "absolutely disgusting".
Speaking to BBC radio programme Five Live, Mr Hunt said: "I think [Nigel Farage] needs to make it absolutely clear that it's not Ukip's view".
Asked if he thought the comments were racist, Mr Hunt replied: "Yes I do. I think it is and that's why I'd like to hear a very clear denunciation of that from Nigel Farage.
"I think it's totally unacceptable and (Lenny Henry) is as British as you and I are."
A Ukip spokesman said that any breach of party rules would be investigated, but also criticised the exposure of candidate William Henwood's tweet by "the other parties."
A spokesman for the party told the BBC:
Any breach of our rules will be duly investigated and action will be taken.
However one has to question why the other parties are spending hours behaving like secret police and trawling through the social media of Ukip candidates who are everyday men and women, rather than actually doing politics.
Perhaps if they did they would be better able to tackle us on policy, rather than having to rely on smear campaigns to try to undermine Ukip's increasing popularity.
Were we to return the favour we would find an even greater wealth of embarrassment and disgrace in the other three parties' ranks to also spread across the media.
