A consumer advisory has been issued by the Iowa Department of Public Health, Johnson County Public Health, and Iowa Department of Inspections and Appeals (DIA) for sorghum made by Ozark Country Sorghum in Dunnegan, Missouri.

Laboratory tests conducted by the State Hygienic Laboratory at the University of Iowa indicate the product has extremely high nitrate levels, which can be especially hazardous if consumed by infants and children, according to DIA Food and Consumer Safety Bureau Chief Steven Mandernach (how to pronounce?). IDPH and Johnson County health officials are investigating two cases of possible methemoglobinemia associated with the consumption of this sorghum, and IDPH Medical Director Dr. Caitlin Pedati says no one should eat this product and it should be thrown away. Signs and symptoms of methemoglobinemia include shortness of breath, cyanosis, confusion, headache, fatigue, exercise intolerance, weakness and dizziness. Those with methemoglobinemia should be seen by a clinician.
