The Situation of Counterfeited and Mislabeled Commercialized Edible Mushrooms in China and the Development of Possible Controls.

Edible mushroom products, encompassing both cultivated and wild varieties, are highly favored by consumers due to their rich nutritional profiles, including significant levels of proteins and amino acids. These mushrooms have extensive applications across the food, pharmaceutical, and cosmetic industries, making the edible mushroom industry a vital component of global poverty alleviation efforts. Taking China as an example, the country produces over 45 million tons of edible mushrooms annually, accounting for 94.01% of the world's total production, thereby establishing itself as the leading global producer of edible mushrooms. However, alongside the rapid expansion of this industry, concerns have emerged regarding counterfeit products and incidents of poisoning resulting from the consumption of toxic wild mushrooms. As follows, to advance the development and integrity of the mushroom production and processing industry: (1) This study presents the situation of counterfeit edible mushrooms and elucidates the factors contributing to the production of fraudulent products from both subjective and non-subjective perspectives. (2) We provide a detailed introduction to 22 varieties of freshly cultivated edible mushrooms and commonly encountered wild edible mushrooms in the Chinese consumer market, proposing the application of DNA barcoding, environmental DNA analysis, and other technologies for the future authentication of counterfeit mushroom products. (3) Concurrently, we present an overview of mushroom poisoning incidents in China from 2010 to 2023, emphasizing the challenges in mitigating the risks associated with wild mushroom consumption and preventing food poisoning, thereby necessitating heightened consumer caution. (4) Finally, we offer four recommendations aimed at ensuring the healthy, stable, and sustainable growth of the edible mushroom industry.
