Health officials said on Friday that more than 300 people reported ill and at least three were hospitalized, after eating at an Olive Garden restaurant at Indianapolis last weekend, a day after the declaration on the outbreak of E.coli at Taco Bell restaurants.
The restaurant is closed temporarily and health officials along with the company are investigating on the cause.
Leftover food and stool samples were collected from those stricken for finding out the source of the illness. The investigators said that it would take at least 48 hours for them to report on the test results.
A company spokesman said that the customers were complaining about symptoms of nausea, vomiting, fever and diarrhea.
This becomes the third U.S news on the widespread customer illnesses linked with restaurants around the country.
However, no spokesmen for Darden Restaurants Inc., parent company of Olive Garden, were available immediately to comment on this issue.
