The Copenhagen Post reports that food minister, Dan Jørgensen, has announced that he wants an explanation regarding the listeria outbreak that has claimed 12 lives in Denmark since September 2013.

Yesterday, the food product authorities Fødevarestyrelsen closed down the suspected supplier of the bad sandwich meat responsible for the infection, Jørn A Rullepølser, but now it has emerged that Listeria was first found in the company’s products in May.

Three weeks after the May findings, Jørn A Rullepølser was cleared, despite the fact that five people at the time had been infected with the bacteria.
