An investigation by the NDR consumer magazine ‘Markt’ has identified significant quality defects in various porcini mushroom products sold in German supermarkets. Testing of frozen, dried, and pizza-based products revealed maggot damage, worms, decayed parts, and even a plastic thread in some samples.

Experts, including mycologist Nadja Frotscher and chef Jens Rittmeyer, noted that frozen porcini products from EDEKA (‘Herzstücke’) and Niklas (sold at Kaufland) exhibited worm tunnels in the stems and caps. While EDEKA stated that worm damage was not identifiable and attributed certain structures to natural tissue, Niklas noted that insect infestation could not be entirely ruled out. Consumer protection representatives characterized these findings as violations of established guidelines for edible mushrooms.

Subsequent laboratory analysis commissioned by NDR found elevated levels of Bacillus cereus in all tested products, a bacterium capable of causing gastrointestinal illnesses. Additionally, a consumer complaint highlighted a discrepancy in Exquisa porcini champignon cream cheese, which reportedly contained only 0.7 grams of dried mushrooms and 0.3 grams of porcini powder per 100 grams, despite prominent mushroom imagery on the packaging. Experts warned that severe infestations could lead to protein decomposition and stomach discomfort.
