CNBC's Jim Cramer said Monday he was at a loss with regard to Chipotle Mexican Grill's situation.
"We're not used to this. We don't know what to do," Cramer said on "Squawk on the Street."
The fast-casual restaurant's stock plunged Friday after the Centers for Disease Control and Prevention reported that the E.coli outbreak hindering the company had widened to a total of six states. Still, Chipotle shares were up 5 percent late morning Monday.
