Over the last several weeks I have been monitoring the FDA and CDC as both of our premier public health entities tried to track down the likely vector sickening people across several states with E. coli O121.  Earlier today, they both announce the vector – cake mix from a yet unknown manufacturer – as the cause of the outbreak.  Despite the announcement as of several hours, not one national, or for that matter, more local, media outlet has publicized the outbreak and warned consumers about the risk of consuming unbaked flour and/or cake mix.

Media, you have to do better.

State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the eight people interviewed, six (75%) reported tasting or eating raw batter made with a cake mix. People reported buying different varieties and brands of cake mix.

FDA is conducting a traceback investigation using purchase records from locations where sick people bought cake mix to try to determine a common cake mix brand or production facility.

CDC advises people not to eat raw cake batter, whether made from a mix or homemade. Eating raw cake batter can make you sick. Raw cake batter can contain harmful bacteriaBacteria are killed only when raw batter is baked or cooked.
