Metro and Aldi Süd retail chains in Germany are implementing restrictions on the sale of essential goods like vegetable oil and flour due to high demand and potential shortages. Germany relies heavily on exports, especially from Ukraine, to meet its sunflower oil demand, and may also face shortages of rapeseed and linseed oil. The Federal Association of the German Food Trade has urged consumers to avoid stockpiling and to purchase only what they need to show solidarity and prevent shortages for others.
