The goods seized included scarves, CDs and tapes and breached licence conditions which do not allow items to be sold of a political, racial, religious or sectarian nature.
During the sweep on the traders, officers were spat at as they attempted to carry out their duties.
Deputy council leader Jim Coleman said:
'It astounds me is that people think they can openly sell this sickening material without fear of detection. We have been working closely with both football clubs to eradicate this kind of behaviour. This is another example of a successful operation - one we will be repeating wherever these people try to sell their wares.'
Reports on the licensed traders will be sent to the council's licensing section for appropriate action.
