Colorado press reports that the Colorado Department of Public Health and Environment are investigating an outbreak of E. coli O157:H7 in Aurora. The outbreak was reported at Pho 75, an Aurora restaurant located at 2050 South Havana Street.

So far, four ill people have been identified, but as with any outbreak, it is possible that there are more sick than reported, as some might not go to the doctor. One of the four ill was hospitalized.

The Tri-County Health Department is working with the restaurant during the investigation. Pho 75 voluntarily closed yesterday. According to the state, typically when a restaurant closes in this kind of situation, a list of requirements must be met before they are allowed to reopen.
