Health care Authorities are investigating the source of a Three Kings Day Cake that made nearly 40 people sick with unusual symptoms including hallucinations.

Made by Cholula's Bakery in Santa Ana, the fruit cake was delivered to 10 stores including two in San Juan Capistrano and one Long Beach. Orange County Health Care Agency Spokeswoman Nicole Stanfield confirmed to Patch that the agency is testing the cake to determine what substance sickened so many people. Until the results come back next week, the agency will not rule out the possibility that the cake was laced or that a chemical was leached into it, she confirmed.

The symptoms reported by those who ate the cake - shortness of breath, hallucinations, dizziness - are atypical of food poisoning, which typically focuses its fury on the gut. "Assuming the ingredients were really wheat, salt, eggs, that sort of stuff, hallucinations would not be common. If you put LSD into something, you might see some of these symptoms," Dr. Carl Schultz, a professor of emergency medicine at UC Irvine told The Orange County Register on Friday.

According to the health care agency's website, Cholula's Bakery has a long history of problems including 32 citations over two years for everything from cockroaches and vermin to lack of handwashing supplies for employees. The Orange County Health Care Agency closed the bakery on Wednesday and suspended its permit, citing cockroach infestation.

The "Rosca de Reyes" was delivered Monday and Tuesday, and retailers and consumers were told to throw out any Rosca de Reyes from Cholula's.

Wednesday night, Santa Ana police started getting word of multiple patients with stomach aches from Western Medical Center in Anaheim and St. Joseph Hospital in Orange.

"The common denominator is they ate Rosca de Reyes," Santa Ana police Cpl. Anthony Bertagna said. Most of the calls came from St. Joseph's, and investigators later found four victims at Western Medical Center, Bertagna said.
