I found these suppliers via internet search. I have ordered from Nordisk Import (they are the closest to where I live plus they offer pølser made to a Danish recipe - but no carmine dye). I was very satisfied with their service and product. I have not yet tried the other listed suppliers

I ordered from a Danish imported food supplier closest to where I live. They also have a local butcher make pølser. The order also included: agurkesalat (pickles) and tomat ketchup.
