The FDA, CDC and state and local officials investigated reports of illnesses associated with Uncle Ben's Infused Rice Mexican Flavor in Illinois, North Dakota and Texas. On October 30, 2013 three children in daycare and one college student in North Dakota experienced flushing reactions 45 minutes after consuming an Uncle Ben's Infused Rice product. On December 4, 2013 the Illinois Department of Public Health learned of 25 children who experienced flushing on the ears, arms and necks. These reactions occurred within 30 minutes of consuming Uncle Ben's Infused rice. All of the children recovered in 90-120 minutes. On February 7, 2014 the FDA was notified of cluster of illnesses at three schools in Katy, Texas. Twenty-nine students experienced burning, itching rashes, headaches and nausea for 30 to 90 minutes before the symptoms went away. The FDA tested rice that was leftover from the Illinois school lunch and the results of this testing showed an increased amount of niacin, or Vitamin B3, in the rice. Overexposure to niacin can lead to skin reactions such as redness and flushing, itching, and dry skin. Mars Foodservices agreed to recall all bags and lot numbers of its Uncle Ben's Infused Rice products produced in 2013.
