Public health officials in South Carolina are investigating an E. coli O157:H7 outbreak linked to a Spartanburg-area Mexican restaurant. At least 11 people have confirmed or suspected infections.

Out of three victims interviewed thus far, two infections have progressed into hemolytic uremic syndrome — or HUS — a kidney disease associated with severe E. coli infections.

The South Carolina Department of Health and Environmental Control has declined to name the restaurant involved in the outbreak, though readers of the local news site have said it is El Mexicano in the Hillcrest neighborhood. Food Safety News cannot confirm this information.

Illnesses occurred between the last week of April and the first week of May. As the state health department continues its investigation, an official told that the restaurant no longer poses a public health threat.

Health officials recommend anyone with symptoms of E. coli infection such as diarrhea or abdominal cramps contact a health care provider. Those with potential E. coli infections should not be given antibiotics, as they can worsen symptoms.
