evidence: Posts on Facebook falsely claim all McDonald’s French fries come from Bill Gates and a "genetically modified potato farm". [...] The text on the image says: "in case you didn’t know every single McDonald’s french fry comes exclusively from Bill Gates and genetically modified potato farm. EVERY SINGLE ONE. [sic]" This is not true. [...] The claim in the posts may have come from reports that Mr Gates’ investment firm, Cascade Investments, owns a farm named 100 Circles Farm, which is listed as a potato supplier on the McDonald’s USA website.
