Department spokesperson Laura McCasland told Food Safety News that four of the seven who tested positive for E. coli first exhibited symptoms for the pathogen.
McCasland said department investigators do not believe they are dealing with an ongoing outbreak. While the source has not yet been identified, they have no evidence that any retail grocery store is involved.
Food Safety News first learned of the Sacramento County outbreak from a reader who claims to have two children among the infected individuals. That source said that there are three hemolytic uremic syndrome, or HUS, cases among the seven individuals.
