NEW YORK (Reuters) - Chipotle Mexican Grill on Monday denied allegations by actor Jeremy Jordan that eating at one of its restaurants landed him in the hospital.

Jordan, who plays Winn Schott on TV show Supergirl, posted an Instagram video on Thursday of himself on a hospital bed, saying that the food he ate at a Chipotle made him severely sick and that he "almost died", according to a People.com report.

"There have been no other reported claims of illness at the restaurant where (Jordan) dined. We take all claims seriously, but we can't confirm any link to Chipotle, given the details he shared with us," Chipotle spokesman Chris Arnold said.

Jordan's allegations come as Chipotle is still recovering from a bruising string of food safety lapses that started in late 2015, including a recent norovirus outbreak at a Virginia restaurant.

The Denver-based burrito chain's stock has fallen about 60 per cent since an E. coli outbreak in 2015.
