Fast food fans have discovered a UK supermarket is selling a beloved McDonald’s product that was axed.

The McRib is a pork burger with barbeque sauce, onions and pickles on a soft roll. It was introduced in 1981 and gained a dedicated following before leaving menus in 2014.

But now a customer believes they’ve found the patties on sale, meaning fans only have to assemble the sandwich at home to have an authentic McRib.

The rare item was found in Company Shop, a retailer that sells surplus stock from supermarkets and restaurants at low prices.

Stock at each of the 13 stores changes daily, depending on what they receive from suppliers. In addition to products from M&S, Tesco, Waitrose, and Sainsbury’s, you might find Cadbury, Mr Kipling, Walkers, Doritos, and more.

“We often get surplus food in from some of the big fast food chains,” a Company Shop employee told Metro. “We’ve had stuff from McDonald’s, KFC, and Greggs.”

However, the stock is repackaged and sold unbranded, so costumes must be eagle-eyed to be able to spot their favourite brands.

Most recently social media users claim to have found McRib patties in one of the stores. A food blogger (@uknewestfoods) shared a look at the find on Instagram.

The clip shows 10 frozen pork patties, each with those iconic rib ‘ridges’, being sold in a 1kg pack for £2.50.

There is no McDonald’s branding anywhere, though the sign above the freezer refers to the products as ‘legendary rib patties’.

Though it hasn’t been confirmed that they are authentic, it would make sense that there might be some surplus stock of the burgers as the McRib was brought back for a limited time last winter.

However, not everyone will be able to get their hands on the patties, as customers require memberships to shop in the Company Shop. Criteria include working in the emergency services, and armed forces, or being on means-tested benefits.
