Certain dyes in foods, when mixed with certain foods will cause all sorts of odd colorations. Think green stools after blue jello. Also, foods like spinach and collards, oysters and clams, and liver are very high in iron and can make the stool very dark. As long as it was a one time event I am sure that there is no cause for concern.
