This is a ridiculous claim and entirely false (just go look at the online grocery sites e.g. https://www.ocado.com/browse/fresh-chilled-food-20002/vegetables-44330/onions-leeks-garlic-44331?showOOS=true https://www.ocado.com/browse/fresh-chilled-food-20002/vegeta... ). I have never experienced this in the UK. What kind of shops are you guys going to in the UK? Red onions, brown onions, white onions (normal, large, bulk bags, loose or bagged, pre-chopped etc), shallots, echalions, spring onions, red spring onions, tropeas etc (them also organic + non-organic varieties of each) are all normal to see in UK super markets (at least in my local part of London). Even Tesco - a chain that many would say is the lowest of the low super market "for poor people" in the UK - carries these.
