Man left ‘sweating and shaking’ after disgusting McDonald's burger surprise has him ‘vomiting’

A McDonald's customer in Australia said he was left 'sweating and shaking' after he stopped in to one of the restaurants for a Quarter Pounder burger.

The meat-filled Quarter Pounder is a popular choice for fans of the fast-food chain, and was just what Queensland man Anton Vallely was craving after having a few drinks last weekend (25 November).

He picked up his order from the Coolum store on the Sunshine Coast at about 2am and didn't hesitate to sink his teeth into the burger, but his enjoyment was unfortunately short-lived.

Vallely noticed the burger had a strange taste, so used his phone's flashlight to get a better look at the meat.

He realized the two patties that make up the Quarter Pounder appeared to be only partially cooked, and he claimed to quickly start feeling a strange sensation in his throat.

“I was sick as soon as I realised and now my throat feels weird and I’ve been sweating," Vallely, who plays in a band, told news.com.au after the ordeal.

He went on to say he'd been 'sweating and shaking' since eating the burger, adding: “I feel like there’s been a difference in my singing as well from the vomiting."

While Vallely did not feel unwell enough to go to the doctor, he felt it was 'worth saying something'.

Describing the incident as 'unacceptable', Vallely expressed concern that undercooked food could have serious consequences for other customers, for example pregnant people.

The customer called McDonald's to inform the company of what had happened, and has since taken the burger back to the store so it could investigate.

In a statement about the complaint, a McDonald's spokesperson told UNILAD: “McDonald’s takes food safety extremely seriously and follows strict processes and procedures to ensure the quality of our food.

“We can confirm McDonald’s Coolum Beach received a complaint regarding an undercooked beef patty on Monday, 27 November.

“We immediately investigated the claim and offered the customer a full refund and replacement meal.

“We treat complaints of this nature very seriously and will continue to work with the restaurant on the necessary actions.”

Though McDonald's offered Vallely a refund and a replacement meal, Vallely said he'd been turned off eating the fast food.

While speaking about the incident, Vallely acknowledged that a friend who ordered from McDonald's at the same as him was served a burger that had been properly cooked through.

UNILAD has contacted McDonald's for comment.
