Outline
To analyse of foodborne pathogen contamination in edible fungi sold in Chongqing from 2022 to 2024.
A total of 700 samples of wood ear and tremella were collected in 2022—2024 and tested for Listeria monocytogenes, Salmonella and Burkholderia gladioli according to the requirements of the national food safety standards.
A total of 112 positive samples were detected among 700 samples, with a detection rate of 16.00%. The detection rates of Listeria monocytogenes, Burkholderia gladioli and Salmonella were 7.14% (50/700), 6.86% (48/700) and 3.14% (22/700), respectively. The detection rates of pathogenic bacteria in rehydrated and fresh edible fungi were 20.00% (19/95) and 18.69% (94/503), respectively, which were significantly higher than that in dried edible fungi (6.86%, 7/102). The detection rate of foodborne pathogens in bulk edible fungi (including self-made simple packaging) was 18.41% (118/641), which was higher than that in pre-packaged products (3.39%, 2/59). Among the different sampling locations, the detection rate of farmers’ market was the highest at 22.84%(82/359), and the lowest at 2.27% (1/44) in online shops.
The edible fungi sold in Chongqing are more seriously contaminated by Listeria monocytogenes and Burkholderia gladioli, with rehydrated and fresh edible fungi posing a particularly higher risk of foodborne diseases. The degree of pathogenic contamination of edible fungi is related to the type of packaging and the distribution link. In this regard, it is recommended to strengthen the supervision of the whole chain of production, circulation and sales, form a closed-loop disposal of the whole process of traceability, and carry out science popularization activities through multiple channels to enhance the public risk awareness and protect consumer health.
