Surströmming, of fermented herring, is a strong-smelling delicacy, sold in cans that swell in storage.
Four airlines – British Airways, Finnair, Air France and KLM – have banned passengers from carrying the cans on the plane, Aftonbladet reports.
The airlines then requested airport authorities to ban sales of the delicacy. Svenska Dagbladet quoted Yvonne Nordin at Scandinavian Service Partner, which runs a number of shops at the airport, saying that she had been told that the cans were a security risk.
But Ruben Madsen, who produced the particular brand of smelly fish that used to be sold at Arlanda said the ban was introduced by “cultural illiterates”.
He said that it is a myth that surströmming cans can explode, as the pressure is not high enough. He admitted that they could leak, but claimed that his vacuum packed surströmming were leak-proof.
