Taco Bell executives are doing damage control after a picture of an employee licking a stack of taco shells goes viral. The picture showed up on Facebook and has been shared hundreds of times.

Taco Bell spokesman Rob Poetsch told The Huffington Post that the company has, “strict food handling procedures and zero tolerance for any violations.”

“When we learned of the situation we immediately contacted this restaurant’s leadership and although we believe it is a prank and the food was not served to customers, we are conducting a full scale investigation and will be taking swift action against those involved.”

Taco Bell is conducting a full-scale investigation.  The photo shows a guy licking a stack of about 30 taco shells.
