• Earlier this week, an unidentified man in Colorado was hospitalized after eating a Taco Bell meal that allegedly contained rat poison.
  • In a Friday update on the investigation, the Arapahoe County Sheriff’s Office said that investigators confirmed there was rat poison in the food through lab tests.
  • However, investigators also examined surveillance video from Taco Bell over the past several days, and found “no evidence that the employees were responsible.”

Authorities in Colorado said there was rat poison in the food a man ate after he visited a Taco Bell earlier this week — but investigators said there was no evidence that employees at the fast food chain poisoned his meal. 

The man, who has not been publicly identified, went to a Taco Bell in Aurora Sunday afternoon, Arapahoe County Sheriff’s Office public information officer Deputy John Bartmann told USA TODAY on Thursday.

Officers responded to a verbal disturbance call at the restaurant’s drive-thru at around 1 p.m., after the man argued with employees because the soda machine was not working.

He became angry and asked for a free burrito to replace his drink. Eventually, employees gave the man the burrito and he left. Deputies found that “no criminal activity” occurred, the Sheriff’s Office said Friday.

But later, the sheriff’s office dispatch received a call from an area hospital at around 7:50 p.m. that evening. The hospital said that they had a male patient who had “possibly ingested rat poison,” Bartmann said.

Deputies who responded to the scene found that the patient was the same man from the earlier incident at Taco Bell. The man told officers that, after doing yard work and watching some TV, he ate his Taco Bell food at around 7 p.m.

“He took took a bite into one of the tacos and immediately felt a burning sensation and then started to get sick,” Bartmann said – adding that the man then called 911 and was soon transported to a hospital, where he told staff he had eaten food with rat poison in it.
