General Mills widened its recall of potentially contaminated flour Monday, and health officials said 46 people have been made sick so far by raw flour.
The flour was contaminated with toxic E. coli bacteria, the Centers for Disease Control and Prevention says.
"Four more ill people have been reported from two states. The most recent illness started on June 25, 2016," the CDC said. Two different types of E. coli have been found in the flour. The total: 46 people made sick in 21 states, NBC News reported.
"Epidemiologic, laboratory, and traceback evidence indicate that flour produced at the General Mills facility in Kansas City, Missouri is a likely source of this outbreak," the CDC added.
General Mills has a complete list of the affected flours on its website.
