Over 130 people have now reported that they got sick after eating at a Sterling, Va., Chipotle Mexican Grill (CMG - Get Report) restaurant, Business Insider reported.

Chipotle reopened the location yesterday after closing it for a two-day "thorough sanitization," but the bad news continued today. Website iwaspoisoned.com showed 133 people reported being sick after eating at the Chipotle location. The original report was only 13 people.

The local health department is investigating the cause of the illness.
