Over the past five years, the discount retailer has also managed to quadruple its turnover from organic products.
In addition, the analysis of data from NielsenIQ Switzerland's combined household/retail panel showed discounters as the second most important sales channel for organic food.
Lidl Switzerland also organises four major organic weeks per year, each with more than 100 extra organic products.
'High Quality At Fair Prices'
Kassandra Marty, responsible for sustainability in purchasing at Lidl Switzerland, noted that the Swiss population appreciates the fact that the "smart discounter" can offer high quality at fair prices - an important factor in the organic sector.
Many of the organic products come from Switzerland and are therefore also produced strictly in accordance with Bio Suisse guidelines, a label classified by the PUSCH (Praktischer Umweltschutz) environmental foundation as 'very recommendable'.
In the fruit and vegetable department, Lidl Switzerland offers up to 40 organic products, depending on the season.
Currently, more than a quarter of all its fresh beef offering is organic, in combination with free-range.
Lidl Switzerland plans to continue expanding its organic range and strengthen its commitment to organic farming.
