Horror reports appear in the German press about adulterated Italian olive oil that was allegedly also exported to Switzerland.
Such machinations are unsettling and saddening. At least they have been uncovered.
Can Migros comment on this?

Excerpt from the Tagesspiegel of December 24, 2011:

Italian olive oil adulterated

According to a media report, 80 percent of the olive oil sold as "Italian" is apparently cheap oil that Italy has imported from Spain or Tunisia.

Berlin - Following the scandal surrounding counterfeit organic food, Italy is now facing its second major food scandal in just a few weeks. According to a report in the newspaper "La Repubblica", 80 percent of the olive oil sold as "Italian" is cheap oil that Italy has imported from abroad. The oil is falsely declared or misleadingly labeled, the newspaper reported on Friday, citing investigations by customs and the financial police. "There is a powerful group in the food industry that is making an illegal fortune through imports because the mixing of the oil cannot be proven," the newspaper quoted Coldiretti, the consumer representative of the farmers' association, as saying.

According to the newspaper, the companies import oil from Spain, Greece, Morocco and Tunisia. In some cases, they pay less than 25 cents per liter. Some of the oil is then treated and some is immediately blended with Italian oil. The Italian food companies then sell the oil as "olive oil from Italy" to discounters, tourists and wholesalers - for three to four euros per liter. In total, the companies made an annual turnover of five billion euros. According to the newspaper, the foreign producers and exporters are often subsidiaries of Italian importers and olive oil producers.

According to "Repubblica", the companies conceal the mandatory indications that it is a blend. If they do exist, they are printed so small that they cannot be seen on the labels. According to the report, the deception about the origin of the oil is compounded by the fact that the oil sold is often of poor quality and contains traces of mold or lubricants. The newspaper did not name the companies involved - according to its own statements, in order not to jeopardize the ongoing investigation.

Just two weeks ago, another food scandal was uncovered in Italy. According to the authorities, a gang of counterfeiters is said to have sold around 700,000 tons of allegedly organic goods worth a total of 220 million euros over several years. They are said to have bought conventionally produced cereals, soya, flour and fresh fruit in Italy and Romania and re-labeled them as organic products. Organic food can be sold at a significantly higher price. The public prosecutor's office in Italy is investigating 40 companies, including Sunny Land, Marinucci, Bioagri and La Spiga in Verona and Bioecoitalia in Fano.

According to the investigation, the majority of the goods went abroad - to Belgium, France, Spain, Austria, Switzerland and the Netherlands. A large proportion is also said to have been delivered to Germany, but it is not yet known exactly how much. However, it is at least known which products are involved. The goods sold to Germany are said to have been mainly animal feed such as soy and rapeseed. According to the authorities, there was no health risk for consumers, but the products in question may not be sold as organic goods.
