California will consider a law allowing organic farmers and others to sue if a neighbor's genetically-modified crops damage their harvest. Genes, often inserted into crops to boost disease or chemical resistance, have leaped from field to field, leaving farmers that want am all-natural crop vulnerable to the whims of their neighbors and the wind.

Organic products can't contain engineered ingredients.
