'The safety of customers and team members is a priority,' Taco Bell Corp. says in a statement

A Taco Bell customer in Colorado claims he was hospitalized with rat poisoning, and now the local sheriff's office is investigating.

Arapahoe County Sheriff’s Office told FOX 31 they received a report of a disturbance in the drive-thru of the fast food restaurant off East Smoky Hill Road in Aurora around 1 p.m. Sunday.

A customer allegedly got into an argument with the employee because the soda machine was not working.

Later that day, around 7:50 p.m., the sheriff's office said the customer involved in the argument was taken to the hospital after ingesting what was believed to be rat poisoning in his food.

The man told deputies he had waited until around 7 p.m. to eat his food, then became very ill and called 911 before being taken to the hospital. 

Investigators went to the Taco Bell and the man's house to retrieve any leftover food for testing. The sheriff's office said they are going through video from the Taco Bell while looking into the man's claims.
