On September 17, 2016 a Harvest Moon Dinner was hosted by Grant Farms in Wellington, Colorado. The menu included a roasted hog and steamed corn cooked at the farm. Other menu items were prepared at a licensed facility in Wyoming. Unpasteurized milk was also consumed by some of the guests. Six people became ill with diarrhea following the dinner. One person was laboratory confirmed with Campylobacter. No one was hospitalized and no one died. Because many of the guests ate the same items, it was not possible to determine the source of the outbreak.
