Politicians have been urged to send a consistent and clear message to constituents that they reject racism.
Mr Joe McDonagh, chairman of Know Racism, the national anti-racism awareness programme, said all elected representatives must be responsible in their comments about non-nationals and minority groups living here.
There were now over 160 nationalities working and living in the State, "the vast majority of whom are making a very positive contribution to the economy and Irish society", he said.
Most people involved in politics supported the development of an inclusive and multicultural society.
"Irresponsible and ill-informed comments by elected representatives on these issues could be very damaging and potentially dangerous," Mr McDonagh said.
The growth in reported incidents of racist attacks in the aftermath of September 11th showed how racism could be "stirred up by a major event or by irresponsible commentary", he said.
Know Racism has called on political parties to ensure that their candidates and election agents know their parties' commitments under the anti-racism protocol for political parties.
"Those standing as independent candidates should indicate their support also for the principles outlined in the protocol," Mr McDonagh said.
Know Racism provides a €3,800 grant to political parties to help them to raise awareness of racism and promote cultural diversity.
