An Australian customer has expressed his disgust at finding a raw chicken fillet in his burger from a popular fast food chain.

The man posted a picture to Reddit of the meal he received from Hungry Jack’s Herston store in Brisbane on Sunday night.

The burger was cut in half to reveal the raw chicken inside the bun, which also had mayonnaise and lettuce.

“So glad my partner and I decided to share this Hungry Jack’s Fried Chicken Burger,” he captioned the photo.

‘Pinker than pink. Hungry Jack’s Herston hands out salmonella.’

The burger, which was described as “hot meat flavored jelly”, was free as part of the chain’s current UNO promotion.

“(It) just went straight in the bin,” the customer added.

“On the downside, from now on I’m going to be super squeamish about any takeout chicken burger.”

The image sparked shock and anger from Australian fast food fans.

‘Please report it. Enough to kill someone, one pleaded.

Another: “Salmonella can be a big deal for some people.”

A third wrote: ‘I was hospitalized with Salmonella poisoning as a child. It was bloody awful.’

Others were concerned how the incident happened in the first place.

“It’s possible a new employee pushes the wrong button on the fryer so when they pull it out they think it’s cooked because the outside is dark,” wrote one.

Another added: “Staff probably mistakenly pressed the chicken royale timer (two minutes and thirty seconds) rather than the JFC timer (nine minutes) on the fryer.”

One spat sarcastically: “How could a 13-year-old chef make such a basic mistake?”

Another customer in Brisbane claimed she had similar food issues from the same Hungry Jacks store.

“Herston is also our nearest location and every time I’ve ordered there it’s been absolute dogs,” said one woman.

“Stale chips, chewy and overcooked steaks, we’ve become a strict no-HJ household,” she said.

The man who originally shared the photo has since reported it to both Queensland Health and Hungry Jack’s

He said the restaurant’s district manager for the Brisbane store had contacted him and also believed it could be due to a fault with the cooking button.

“She mentioned what a lot of people have said in this article that the wrong button was probably pushed and the chicken was cooked too quickly,” he said.

A Hungry Jack spokesperson told Daily Mail Australia that food safety was the chain’s “top priority”.

“Hungry Jack’s has rigorous quality assurance processes and appropriate training systems in place,” they said.

“Hungry Jack’s became aware of the complaint late Sunday night and has contacted the customer.”
