South Africa is experiencing price increases in restaurants and fast food outlets due to a sunflower oil shortage. The shortage, largely attributed to the ongoing conflict in Ukraine and recent crop failures, is worsened by South Africa's heavy reliance on imports from Russia and the EU. The situation has led to panic buying of staple food items in several cities. Potato growers have warned of potential price hikes for chip suppliers due to the widespread use of sunflower oil in the fast food industry.
