LSD tainted beef that came from Wal-Mart is being blamed for sickening a Florida family, including a pregnant woman and two young children.

Police are investigating an incident involving a Tampa, Fla., family who reported having hallucinations after eating meat found to be tainted with LSD last week.

The family of four, including Rosado Morales, who was nine months pregnant, and husband Ronnie Morales bought the packaged bottom round steak, supplied by Cargill, from a Wal-Mart in Tampa. 

"We know our customers expect safe, quality food and we require our suppliers to meet the highest of food safety standards," said the store in a statement.  "It’s unclear where and how the food was tampered with or if the tampering occurred after purchase."

The store is reviewing surveillance tapes to see if the contamination happened at the store.

After eating the meat last Monday, Ronnie became ill, and shortly after, Rosado and her husband were hospitalized. The two daughters, 6 and 7, said they experienced hallucinations. The family was released from the hospital later in the week. 

The Hillsborough County Medical Examiner's Office released tests Friday that showed the meat was contaminated with LSD. 

Wal-Mart is cooperating with the investigation and has pulled all of the product from store shelves, but there's no word on how the drug came into contact with the meat.
