Hospitalised after drinking cleaning fluid in Waitrose coffee

The unnamed woman had visited Waitrose in Lewes, East Sussex, and got a free cup of coffee using her myWaitrose card. However, after some sort of mistake by the supermarket, the coffee somehow contained cleaning fluid, which burned the inside of her mouth, and paramedics were called. She ended up in A&E for hours, and was still unwell five days later.

So how does this rate on terms of the nastiest things ever found at the supermarket?%VIRTUAL-SkimlinksPromo%
