UK heatwave is expected to push more wonky produce onto shelves
Retailers are loosening strict cosmetic standards as drought and heat reduce yields and shorten supplies, with some items like cauliflower affected by yellowing from increased sunlight.
Farmers across the UK are dealing with one of the driest and hottest growing seasons in decades, with repeated heatwaves after a warmer than usual spring raising expectations for the worst harvest since records began, according to BBC Business.
Because retailers often reject fruit and vegetables that do not meet strict size, shape, and color guidelines, sellers say suppliers under pressure may temporarily loosen those rules rather than risk empty shelves, meaning shoppers could see smaller, misshapen, or oddly colored vegetables in the coming weeks.
Cauliflower is highlighted as one of the most affected crops, as it needs lots of water and typically stays protected from sunlight by its leaves, but in this year more light is reaching the heads and turning them yellow. Oddbox co-founder Emilie Vanpoperingh said the issue is cosmetic and that taste is unchanged, adding that the company acquired 6,000 cauliflower heads last week that were too dark for supermarkets to sell.
Other growers are reporting stress-related defects too, including cucumbers grown in overheating greenhouses that can come out misshapen, and pak choi losses driven by pests such as flea beetles that thrive in hot, dry conditions, with pesticide use constrained and net covers used as defense. BBC Business also reports that Harper, who grows pak choi for retailers including Sainsbury's, Aldi, and Co-op, said supermarkets have sometimes “sort of” eased their approach during the hot period.
