A horrified woman recalls the sickening moment she found live maggots writhing in her meal at a popular restaurant chain.

The Blue Mountains woman visited Lone Star Rib House Penrith in Sydney’s west for a “lovely meal” with her husband and son on November 10.

But after the woman’s steak, which can cost up to $65 at Lone Star, arrived, she knew “within seconds” that something was wrong,

“I kind of zoomed in and looked at the piece of steak and thought, ‘This is really strange, there are things moving,'” she said. ABC reported.

Her husband initially suspected it was steak seasoning until he inspected it more closely.

The customer, who did not wish to be named, alerted a member of staff, who told her about the restaurant’s high ratings for food quality and safety.

Despite being offered a replacement meal, the woman refused because she was “disgusted.”

“I just said, ‘No, I can’t eat here…I just want to leave,'” she said.

The waiter took the meal back to the kitchen and the restaurant was later informed that staff did not “know how the maggots appeared on the steak.”

The family was also told that the maggots did not come from the steak but from the salad, which they refuted.

“(The maggots) were having the time of their lives on that piece of steak, and there wasn’t a single maggot on the salad,” she said.

The restaurant added that it didn’t matter what food the live maggots were in: they should never have been on his plate.

The customer is also curious as to why no one noticed the maggots, because “at least two, maybe three people” had handled and prepared the meat before it arrived at the table.

The woman claimed she had yet to receive an apology from the restaurant for the “disgusting” incident which left her “uncomfortable and fearful”.

The customer said she couldn’t eat steak anymore and was cooking her food longer “just to be sure” to kill anything that might be hiding in her food.

Lone Star Rib House told ABC it would not comment on the woman’s video or her “personal opinions” on the restaurant’s hygiene.

A spokesperson confirmed an independent environmental health officer inspected the restaurant the day after the family’s visit.

They said the inspection was due to the maggot complaint.

But no “areas of concern” were found and there were no flies at the scene or any other evidence of maggots.

The report also shows that the restaurant’s meat was stored in sealed bags and the salad was also in a sealed box, with “no possibility of contamination.”

The Penrith Council spokesperson has since launched an investigation and is working with the restaurant and the NSW Food Authority.
