This video was filmed in the relatively new Idea supermarket in the up-scale Usce shopping centre. It illuminates the downright dangerous and immoral tricks played by some Serbian supermarkets.
It is not only Idea. I have had two incidents at the big Maxi at Gospodar Jovanova 39 where I ended up with rotten food.
One one occasion I was sold rotting Skate (fish). On another, I bought a kilo of marinaded chicken, only to spot that it was green and putrescent whilst preparing it.
I am told the supermarkets use the marinade to disguise the rotting, so be very careful when buying any meat in a marinade or sauce.
