The International Atomic Energy Agency (IAEA) is developing new techniques to quickly verify and identify the origin of food products, particularly extra virgin olive oil, in response to a surge in the black market for counterfeit olive oil due to climate change impacts on European harvests. The IAEA's methods, which include near-infrared spectroscopy, have demonstrated an 86 to 93 percent accuracy rate in differentiating between Slovenian extra virgin olive oil and that of other countries. The olive oil shortage in the EU has also created a market for rapeseed oil.
