The Loxahatchee man says he took his finger, dipped it in what he thought was the salt, licked his finger and immediately his mouth started burning.

He was taken to Palms West Hospital where he reportedly sustained second degree burns to his tongue, mouth and throat.

There was a cleaning product containing hydrochloric acid was put on his plate.  How is the big question.

"Sonny's is continuing to investigate this matter.  The container being shown is not part of the standard cleaning products issued from the Sonny's corporate office.  We use an 8-oz packet in our stores, which does not require scoops or spillage," says a corporate spokesperson.  "Our understanding is, the manager provided a material safety data sheet with ingredients of the chemical to Mr. Milstead in order to give to the doctor.  Sonny's still does not know where this other container came from, but we are still investigating."

This is very dangerous. I hope this guy will be ok and no one else was hurt. This restaurant should be closed down until the investigation is over.
