What causes garlic to go green?

Garlic contains sulphur molecules that, when combined with copper, may result in the formation of copper sulphate, a blue or blue-green substance. The quantity of copper required for this reaction is quite minimal, and it may be found in plenty in most municipal water sources. Copper may also be found in other foods, such as butter and lemon juice, among others. The garlic is completely safe to consume.
