The error was first raised by April Frances, from Jersey, on the ‘Dull Men’s Club’, a Facebook group with 145,900 members.
It features discussions on topics like how long traffic lights remain on each colour for, and the variation in the number of segments in satsumas.
Her post sparked hundreds of comments, including many from people asking what are the differences between the two breeds of cow.

Some of the ‘dull men’ called it an “udderly” disgraceful mix-up, a “moo-mentous fail” and a “missteak”.
“Our Finest Whole Milk recently changed from milk from both Guernsey and Jersey cows, to solely Jerseys,” the supermarket responded.
“We are in the process of updating the photo on the bottle to a Jersey cow.”
Among those to joke about the mix-up was Guernsey headquartered Specsavers, which said “Udder’ve gone to Specsavers.”

The story was also picked up by The Sun, and industry magazine Farmers Weekly.
Local meme group ‘Not the Jersey Police’ also made a joke.
Can you spot the difference…?
The Guernsey breed is fawn or white in colour, often with patches of the two. Considered “hardy and docile” the cattle are renowned worldwide for the milk produced.
Jersey cows are similarly renowned for their milk, but traditionally, they are smaller animals than the Guernsey breed with colours across all shades of brown, from light tan to almost black.
They often have a lighter band around their muzzles with dark hooves and a dark switch of hair on the end of their tails.
