"It happened when the ammonia was being transferred between two tanks," the Swedish public broadcaster SVT quoted police spokesperson Peter Adlersson as saying.
The factory's chief executive Magnus Dafgard said, in turn, that "everyone is a bit shocked, because there hasn't been an accident of this kind before," according to Swedish Radio.

Dafgards is one of Sweden's largest food producers, manufacturing ready-made food portions for supermarkets and restaurants, including meatballs for the Swedish furniture giant IKEA.
Six of the afflicted patients have already been discharged, but the other five remain in hospitals in the nearby towns of Lidkoping and Skovde.
