Brits are questioning everything they know after learning how milk is sold in Canadian supermarkets.

When Brits go to the supermarket to buy milk they know exactly what they'll get. Find the dairy aisle and you'll see rows of various sizes of milk - all in plastic bottles or cartons. You used to be able to simply look at the top to see which type you were getting - blue for whole milk, green for semi skimmed and red for skimmed - but now you have to look at the label instead.

So when Brits realised that milk in Canada is sold in bags, they were mind-blown. Musician and content creator Jenna Bennett recently moved to the UK from Canada, and during a visit back home she shared the revelation with her 189k TikTok followers.

In a recent video, she shared: "One thing about Canada, our milk comes in a bag. Yes, a bag," and in the caption, she wrote: "I thought this was normal around the world."

Jenna then showed viewers a 4l bag of "partly skimmed milk", which she explained has three individual bags of milk inside it. "You can also get it in chocolate milk," she said.

Viewers watched on in horror as Jenna pulled out three bags of milk and showed the jug people would put them in when they got home. She added: "Honestly, growing up I thought this was totally normal, and I thought everywhere in the world had these. It wasn't until I got into TikTok that I realised this wasn't normal. That other countries don't have this. So yeah, there's something you probably didn't know about Canada."

Jenna added that she didn't know the pros and cons for having milk in a bag, but one annoyance she would regularly have was leakages - particularly in supermarkets. She explained: "Sometimes in the grocery store the bag will rip or pop, and the bottom of the fridge [...] stinks. Like bad."

She also explained that if you "cut the bag wrong you are screwed until the rest of that bag is finished". There were many reasons Brits were disturbed his this discovery - and there were many potential issues they were worried about.

One person simply said: "That is crazy," while someone else added: "Just looks very inconvenient," and a third wrote: "In the UK we can not imagine telling our other half 'go to the shop and get a bag of milk'," however, someone else remembered: "We tried it in the UK a few years ago. Didn't go well, only lasted a short while.""

Many users were worried about how Canadians would know the expiry date of the milk, but several pointed out that the expiry date would likely be printed on the bag.

Another worried person asked: "How do you close it after use? Do you have to finish it all in one day?," while another asked: "I'm an Aussie how do you pour it out? how long does it stay good in a bag once opened?" Someone else commented: "All I'm thinking about is the spillage!"

According to Ottawa News, milk is sold in bags mostly in Ontario, Quebec and the Maritimes - where the trend really caught on. But that could be changing in the future due to the demand for milk being in decline. "We believe that it is highly likely that bagged milk will disappear within the next decade or so," said Sylvain Charlebois, director of the Agri-Food Analytics Lab at Dalhousie University.
