When I clicked on the article that this is referring it to, it made a link to another article from the New York times and that article claimed that when this outbreak happened it was reported on the CDC website. So, from there I had found what the two commonalities where between the two articles. The same thing that the two articles found was that it was an E.coli outbreak that was spurred from the onions that are used on the quarter pounders. So I went to the CDC website and sure enough there was a report done on the E. coli outbreak linked to Mcdondalds that is found in the onions that are used in the quarter pounders.
