German farmers are warning of a sudden surge in food prices due to the ongoing military actions in Ukraine. The cost of bread could potentially reach 10 euros per kilogram, and some products could disappear from supermarket shelves, such as sunflower oil and certain jams. Prices for various food items are already increasing in supermarkets, with some examples including a 15.6% increase in the price of flour, increased prices for toasted bread and pasta, and a hike in the price of organic coffee.
