A Scot was left horrified after eating her McDonalds breakfast only to discover blue mould on the bun.
The 21-year-old, who wants to remain anonymous, 'felt sick' and 'disgusted' after spotting the blue marks.
She and her boyfriend, also 21, had ordered from the Silverburn Glasgow branch on Saturday morning from JustEat.
But their weekend treat was ruined when her partner spat out the breakfast rolls after realising they looked out of date.
The angry customer said: "I had already ate half of mine when my boyfriend noticed his had blue mould on it and spat it out.
"I felt so sick when I seen it, especially because I had already had so much.
"It was disgusting, I don't know how staff never noticed the mould before sending me it."
The couple who stay in Pollok were then left outraged after contacting McDonalds to complain.
They claim they have not yet been offered a refund or new order.
"We got it from the Silverburn McDonalds in Glasgow, it has put me right off though I won't be ordering from them again.
"I phoned McDonalds right away but they told me to go to JustEat, even though they didn't supply the buns.
"I then contacted them online and they told me the same thing and didn't even mention health risks.
"They told me to come down to the store but I had no way of getting there and didn't want to leave the house that is why I got it delivered.
"I am so annoyed by their response, they don't even care and I never even got a refund.
"I spent around £18 on the breakfast rolls, hash browns, and milkshakes."
A Just Eat spokesperson said:"We take food safety extremely seriously and actively work to raise standards across the takeaway sector. As such, we were concerned to hear about this and are investigating with McDonald's.
"For us, it's really important that our customers have a positive experience when ordering their food online and we're sorry to hear that in this case, this customer's experience did not reflect the standard we would hope to deliver. We are in contact with the customer to issue a full refund."
A McDonald’s Spokesperson said: “We are very sorry to hear about this customer's experience. Food safety is of the utmost importance to us and we place great emphasis on quality control, following rigorous standards to avoid any imperfections.
"It is disappointing to hear we fell short of these on this occasion.
"We are currently conducting an investigation into this incident and will look to keep the customer updated on the outcome via our Customer Services team.”
