Local grocery store El Paso Grande has closed temporarily while the Kane County Health Department investigates salmonella contamination traced to it. There are four confirmed cases and 17 other probable cases under investigation related to the store, according to the Health Department.

Health officials recommend that any noncanned food purchased from El Paso Grande after May 21 should be thrown away.

The source of the salmonella has not been determined, and food testing results at the Illinois Department of Public Health are pending, says the Beacon News.
