Mother finds 'blade' in Sainsbury's chicken kiev

Sophie Perks, a 22-year-old data manager and mother from Swadlincote, Derbyshire, found a splinter of sharp metal in a Sainsbury's chicken Kiev. She had been in the process of serving it to her one-year-old daughter Madison-Faith when she cut into what she described as a 'saw blade'.

So how could this happen, and is this the first time a blade has made it into a meal?
