A severe drought in Canada, the main wheat supplier, and supply issues in Italy have caused a potential surge in pasta prices for UK residents. Durum wheat, a crucial ingredient in pasta, has seen a near 90% price increase this summer. Jason Bull, director of Eurostar Commodities, predicts a 50% hike in the cost of spaghetti, with the price rise likely to begin next month. The high cost is expected to result in pasta shortages in supermarkets, with manufacturers set to pass on the increased costs to consumers.
