A Halal butcher who was asked on video why he did not sell pork products says he felt offended, but kept his calm.

Ayaz Ahmad is a butcher and meat distributor who ended up being the subject of a viral video.

The piece, filmed over the weekend, shows a woman going into a Halal butchers in Swords in north Dublin.

Filming the staff inside the butchers, she asked why that do not sell pork products.

"You're in Ireland, we love our pork", she claimed.

"Pork is one of our national foods in Ireland, we love pork and we're never going to stop eating it".

Halal means the animal is killed differently, with the animal being stunned and being bled out.

Pork products such as rashers and sausages are contrary to Islamic beliefs.

Mr Ahmad, who is originally from Pakistan, has lived here for almost five years.

He told Newstalk: "We do sell some sausages and stuff - they are chicken or beef sausages."

"I said 'This is an ethnic shop - we don't sell everything which you would find in any other supermarket'.

"A simple answer to that question would be you don't sell pork - but that lady tried to trigger me because of my religion or something, to offend me so I would say something bad in return".

"I just kept calm and I said 'no we don't sell pork' but she kept going on... She was making a video about it, I just felt a bit offended but I just tried to keep calm".

"It was a bit embarrassing for the video to go viral, but it's not something which would happen every day".

He said Ireland is "a beautiful country to live in", but that "there are some people out there who would try and offend you on purpose.

"I think those people are ignorant, they just need to be educated".
