Two weeks ago I linked to a BBC article by Clive Coleman about the case of the carbolic smoke ball. He must be doing a series on interesting legal cases, because he's back with a great article about the legal case of the snail found in ginger beer. Quick summary — In 1928 May Donoghue claimed to find a snail in her bottle of ginger beer. Her complaint eventually helped bring about modern consumer protection laws in the UK. The catch: "to this day, no-one knows for sure if there ever really was a snail in May Donoghue's bottle of ginger beer."

I should add this case to my list of Gross Things Found in Food.
