Few shoppers will have failed to notice the “eye-watering” rise in olive oil prices, says Bloomberg. Criminals have spotted an opportunity. In July, Italian police seized 42 tons of fake extra virgin olive oil worth almost $1m, alongside 623 litres of chlorophyll, which was being added to low-grade oil, and 71 tons of something ominously referred to as an “oily substance”. In January, seed oil mixed with beta-carotene and chlorophyll was being passed off as extra virgin in 50 Rome restaurants.
