Hi i bought beef frying steak the other day, (not lean just ordinary) im sure it was beef frying steak, i took it out of packet and put in freezer bags to freeze lol and cant remember if it was frying steak or some other steak now, anyways i thought i would take some out the freezer and cut the fat off the ends for dinner today butttt all through the steak there was little long white bits like long thin worms lol only way i can describe what it looks like, is that fat cause if it is there is now way i can get it all out, there would be frying steak left if id to even give it a go! Hopefully some sane person will know what im talking about 
Thanks
Thanks
