General Mills has announced an immediate recall of more than 10 million pounds of flour over concerns of E. coli contamination.
The Centers for Disease Control and Prevention said Tuesday that federal and state health officials are investigating an outbreak of E. coli O121 that has caused 38 cases of illness across 20 states.
Out of caution, General Mills has announced a voluntary recall of several million pounds of flour.
According to CNN, about half the people who became ill from E. coli reported cooking or baking something homemade before they started feeling sick.
A news release put out by the company states that some of the individuals sickened by E. coli said they used a General Mills brand of flour.
According to General Mills, all the illnesses occurred between December 21, 2015 and May 3, 2016.
"To date E. coli O121 has not been found in any General Mills flour products or in the flour manufacturing facility, and the company has not been contacted directly by any consumer reporting confirmed illnesses related to these products," General Mills said, adding that a number of the individuals also admitted to consuming raw batter or dough, which is never recommended, according to the CDC.
As CNN reports, the immediate recall includes Gold Medal flour, Wondra flour, and Signature Kitchens flour, which were all sold at Safeway, Albertsons, Jewel, Shaws, Vons, United, Randalls, and Acme retailers.
Symptoms of E. coli related illnesses include cramping, diarrhea, fever, and vomiting.
