A mother-of-two was "disgusted" to find a human nail in young daughter’s McDonald’s burger.
Lyn Richie (38) said she felt sick when her six-year-old daughter Ellyn lifted the bun off her Big Mac burger and spotted a nail sitting atop its patty.
“It just sickens me - it seriously makes you questions their hygiene practices,' she told the Daily Mail.
“We definitely will not be returning back to McDonald's ever again.”
The disgruntled family were eating at a McDonald’s restaurant in Derry in Northern Ireland when they made the shocking discovery.
“[Ellyn] doesn't like the bread, so luckily, she pulled the burger apart before she took a bite,” said Ms Richie.
“She said, ‘mummy, what's that?’ with a confused look on her face.”
Alerting a member of staff, Ms Richie, a child minder, said she was offered a full refund when it was confirmed the nail belonged to a human.
“Because I'm a child minder, I always take the kids I care for to McDonald's for a treat.
“But now I just can't trust them, which is a shame, because the kids loved it."
The mother-of-two said she had lodged an official complaint with McDonald’s, who, in a statement, apologised to the family “for their experience in visiting one of our restaurants”.
“We have begun an investigation following this incident and our Customer Service department will be in touch with Ms Ritchie to keep her updated,” the spokesperson added.
“Food safety and quality are our highest priority, and our restaurants and suppliers place great emphasis on quality control.”
