Tesco shoppers have slammed the supermarket for a 'bleak' sign of the times after the retailer put security tags on yet another kitchen staple - its entire range of olive oil. The security measures could be partly due to the rising price of olive oil across Europe. Pictured: The price of the cheapest bottle of 500ml olive oil in each UK supermarket. Ignacio Silva, chief executive of Deoleo, the world’s biggest olive oil seller by revenue, told the Financial Times this week prices have risen so high in Europe that many consumers have stopped buying olive oil altogether. It's meant that Spanish olive oil prices have tripled in the last three years, with Portugal and Greece also seeing year-on-year prices rising by more than 60 percent.
