A Queensland hospital worker has been served a cooked rat inside a burger while on his lunch break.

The medic, who works at Toowoomba Hospital, ordered a burger from Wellbean Co cafe last month.

But when he bit into it he discovered something very wrong, he told The Chronicle.

Sandwiched between the two buns, the man discovered a cooked rat carcass.

He took a photo of the disgusting find and alerted staff, who apologised over the incident.

A Darling Downs Health spokesperson told 7NEWS a review had been conducted into the cafe’s hygiene practices and it has since been cleared for operation.

“We have taken this incident very seriously, with our highest priority being the health and safety of our community, patients, and staff,” the spokesperson said.

“We have been assured that the Wellbean Co cafe operators, the Toowoomba Hospital Foundation, comply with all food and hygiene standards.

“The Toowoomba Hospital Foundation has been in contact with the supplier and has reviewed their process for washing and inspecting all products brought in to the cafe.”

Darling Downs Health says the cafe has apologised to the worker over the stomach-churning incident.
