Cross contamination is what happens when bacteria from one food item are transferred to another food item, often by way of unwashed cutting boards or countertops, as well as knives and other kitchen tools, or even unwashed hands. Cross contamination can in turn lead to food poisoning.

A homograph (from the Greek: ?µ??, homós, "same" and ???f?, grápho, "write") is a word that shares the same written form as another word but has a different meaning. When spoken, the meanings may be distinguished by different pronunciations, in which case the words are also heteronyms.
