Fungus grown food at departmental store in Norway

I was shopping food and other items in a Rema1000, chain of grocery shop in Norway, I was surprised to see an item on rack with fungus grow. It was their with other items and how can the store not see such item and not remove where people are very much sensitive on food or other issues. I remember the issue of Nepal when 'Real' juice had such production mistake, all medias voiced for it and later even Indian ambassador to Nepal has to 'press down' the press by providing more advertisement  to their media or through taking role artists on advertisement and so on. In Nepal or India, we try to hide the issue but in developed countries, they try to explore the mistake and try not to repeat again. I hope the problem of this fungus grow is with broken packet box, not with production system. The mistake might be due to store boy/girl  who didn't see it while putting on rack. Advice to all whether you are in very good store or in street shop, check the item carefully. Special care should be given to check packet condition and its seal and expiry date.
