Öko-Test finds mineral oil and fungal poison in pestos: manufacturer takes product off the market. Some pestos fail the eco-test - the manufacturer withdraws the product from the market What is worrying is the amount of mold toxic fungi found in six pestos.
The majority of the pestos tested performed convincingly in the taste test. The worst grade for taste was still “sufficient” because the Rewe Organic Pesto Rosso was rated as having an inharmonious taste. The test results also show that expensive does not always mean good.
