There have been allegations, particularly in Italy and Spain, that regulation can be sometimes lax and corrupt. [77] Major shippers are claimed to routinely adulterate olive oil so that only about 40% of olive oil sold as "extra virgin" in Italy actually meets the specification. [78] In some cases, colza oil (extracted from rapeseed) with added colour and flavor has been labeled and sold as olive oil. [79] This extensive fraud prompted the Italian government to mandate a new labeling law in 2007 for companies selling olive oil, under which every bottle of Italian olive oil would have to declare the farm and press on which it was produced, as well as display a precise breakdown of the oils used, for blended oils. [80] In February 2008, however, EU officials took issue with the new law, stating that under EU rules such labeling should be voluntary rather than compulsory. [79] Under EU rules, olive oil may be sold as Italian even if it only contains a small amount of Italian oil. [80]

"Olive Oil Production on Bronze Age Crete: Nutritional properties, Processing methods, and Storage life of Minoan olive oil". Oxford Journal of Archaeology 21:1:63–75 (2002). Different names for olive oil indicate the degree of processing the oil has undergone as well as the quality of the oil. Extra virgin olive oil is the highest grade available, followed by virgin olive oil. The word "virgin" indicates that the olives have been pressed to extract the oil; no heat or chemicals have been used during the extraction process, and the oil is pure and unrefined. Virgin olive oils contain the highest levels of polyphenols, antioxidants that have been linked with better health. [71] This section needs additional citations for verification.

Handling of olive waste is an environmental challenge because the wastewater, which amounts to millions of tons (billions of liters) annually in the European Union, has low biodegradability, is toxic to plants, and cannot be processed through conventional water treatment systems. [43] Traditionally, olive pomace would be used as compost or developed as a possible biofuel, although these uses introduce concern due to chemicals present in the pomace. [43] A process called "valorization" of olive pomace is under research and development, consisting of additional processing to obtain value-added byproducts, such as animal feed, food additives for human products, and phenolic and fatty acid extracts for potential human use.

Olive oil is also a natural and safe lubricant, and can be used to lubricate kitchen machinery (grinders, blenders, cookware, etc.). It can also be used for illumination (oil lamps) or as the base for soaps and detergents.
