The El Paso Grande grocery store in Aurora, Illinois is reopening after being closed for about two weeks because of a salmonella outbreak linked to the store. Fred Carlson, environmental health director for the Kane County Health Department, said Tuesday afternoon tests cleared enough store employees so the store could reopen.

The Health Department confirmed 20 cases of salmonella, 19 of them to county residents, and a total of 33 probable cases.

While the source was linked to the deli section of the store where food was prepared and sold, Gross said officials needed to find out if the contamination came into the store from the food or if it was improper food handling that caused the poisoning.
