China is a large producer and consumer of edible mushrooms, with over 350 known edible mushroom species. However, concerns have been raised about the safety of mushrooms from China due to the country's high levels of industrial pollution and the risk of mushroom poisoning. Some studies have found elevated levels of heavy metals and arsenic in Chinese mushrooms, which may pose health risks to consumers. On the other hand, China has implemented stricter food safety regulations since 2015, and the overall pollution level and health risks of edible mushrooms were found to be within a safe range in one study. While the chances of getting sick from dried mushrooms from China are reportedly almost zero, according to an importer, the country has seen a significant number of mushroom poisoning cases, with over 520 poisonous mushroom species identified by the end of 2021.
| Characteristics | Values |
|---|---|
| Arsenic and arsenic speciation in mushrooms | A review carried out for studies on As and As species in mushrooms from China found that arsenic is a natural environmental contaminant to which humans are usually exposed in water, air, soil, and food. China is a high-As region and mushrooms can accumulate different amounts of As and different As compounds, so a potential health risk of As intake may exist for people who consume mushrooms with elevated As contents. |
| Heavy metal pollution | Studies have found that the concentrations of lead, cadmium, mercury, and arsenic in edible mushrooms are higher and more toxic. Heavy metal pollution in A. blazei is serious and deserves attention. |
| Mushroom poisoning | Mushroom poisoning is one of the most serious food safety issues in China, with a total of 196 species identified in poisoning incidents by the end of 2022. In 2023, the China CDC investigated 505 cases of mushroom poisoning, resulting in 1,303 patients and 16 deaths. |
| Xenophobia | Some comment that the fear of consuming Chinese mushrooms may stem from xenophobia rather than actual health risks. China has been open about its air quality issues and food safety issues and has implemented various regulations since 2015 to address these concerns. |

China's mushrooms may contain heavy metals like lead, cadmium, mercury and arsenic
China is a large producer and consumer of edible mushrooms, with over 350 known edible mushroom species. However, concerns have been raised about the safety of consuming mushrooms from China due to potential heavy metal contamination.
Several studies have investigated the presence of heavy metals in Chinese mushrooms, specifically lead, cadmium, mercury, and arsenic. One study from Qingdao, Shandong Province, analysed the content and health risks of these metals in cultivated edible fungi. Other studies have examined the health risks associated with arsenic in mushrooms from China, as arsenic is a natural environmental contaminant that can cause acute and chronic health issues. China is a high-arsenic region, and mushrooms can accumulate varying amounts of arsenic compounds, potentially posing health risks to consumers.
The concentration of heavy metals in edible mushrooms from China has been found to be higher and more toxic than permitted levels. This has raised concerns about food safety, as consuming mushrooms with elevated levels of heavy metals can be harmful. While the overall pollution level and health risks of edible mushrooms in one study were deemed within a safe range, specific species like A. blazei showed serious heavy metal pollution.
To address these concerns, China has implemented various regulations and safety standards for food products, including mushrooms. The National Standard for Food Safety in China sets maximum permitted levels of contaminants like arsenic in edible plants and fungi. Additionally, China has been working to improve food safety and address air quality issues, with stricter consequences for non-compliance.
While the risk of consuming poisonous mushrooms exists, it is important to note that most cases of mushroom poisoning occur when people forage for wild mushrooms without proper guidance. Commercially prepared dried mushrooms, such as those imported from China, are considered safe for consumption, according to experts. However, consumers who are concerned about potential heavy metal contamination can contact importers, who are required to have test results on file for food products.

Mushrooms from China have been linked to poisoning incidents
China is a major producer and consumer of edible mushrooms, with over 350 known edible mushroom species. However, concerns have been raised about the safety of mushrooms from China due to potential contamination with heavy metals and other toxins.
Mushroom poisoning is a significant food safety concern in China, with a growing number of incidents and species identified as poisonous. In 2023, there was an increase in mushroom poisoning incidents compared to previous years, with a total of 97 poisonous mushroom species identified. The most dangerous mushrooms causing fatalities in 2023 were Amanita fuligineoides. Other species causing poisonings include Paxillus orientalis, Paxillus involutus, Cortinarius saturninus, and Pseudosperma ushae.
Several factors contribute to the risk of mushroom poisoning in China. Firstly, China is a high-arsenic region, and mushrooms can accumulate arsenic and other toxic compounds from the environment. Studies have found elevated levels of arsenic in cultivated and wild mushrooms from China, which may pose health risks to consumers. Additionally, there are concerns about heavy metal pollution in edible mushrooms, with higher concentrations of lead, cadmium, mercury, and arsenic detected in some samples.
While the Chinese government and relevant authorities have implemented regulations and networks to address food safety concerns and poisoning incidents, the risk of consuming contaminated mushrooms remains. Some sources advise against consuming mushrooms grown in China due to potential contamination with industrial pollutants and heavy metals. However, others argue that the likelihood of health effects from occasional consumption is slim, and it is more of a personal choice.
To ensure food safety, strengthening the supervision of edible mushrooms, conducting regular risk assessments, and making informed choices to reduce exposure to heavy metal pollution are crucial. Consumers should also be cautious when consuming wild or unfamiliar mushrooms and seek guidance from experienced sources to minimize the risk of poisoning.

The country is a large producer and consumer of edible mushrooms
China is a large producer and consumer of edible mushrooms. However, the country has also been associated with several mushroom poisoning incidents, with over 520 poisonous mushroom species discovered by the end of 2021. The Southwest region of China was the most affected by mushroom poisoning, with poisonings mainly occurring in the summer and autumn months. In 2022, the China CDC investigated 482 incidents of mushroom poisoning, resulting in 1,332 patients and 28 deaths, and 98 mushrooms were identified as causing seven different clinical types of diseases.
Mushroom poisoning is a significant food safety concern in China, and the government, CDCs, hospitals, and mycological researchers have collaborated to address this issue. This collaboration has led to the establishment of a comprehensive network for collecting information, facilitating diagnosis, and providing treatment for mushroom poisoning.
Some people have expressed concerns about the safety of consuming mushrooms grown in China due to the country's high rate of industrial accidents and air pollution. There are worries that mushrooms grown in China may contain high levels of lead and other toxins. However, others argue that these concerns may be influenced by xenophobia rather than scientific evidence.
Studies have found that the concentrations of heavy metals like lead, cadmium, mercury, and arsenic in edible mushrooms from China are higher than in other regions, which could pose potential health risks. For example, a study in Qingdao, Shandong Province, analysed the content and health risks of these metals in cultivated edible fungi. Additionally, a study in the mid-western region of China investigated nine types of common edible mushrooms and found that while the overall pollution level and health risks were within a safe range, heavy metal pollution in A. blazei was a cause for concern.
To ensure food safety, it is recommended to strengthen the supervision of edible mushrooms, make informed choices, and reduce exposure to heavy metal pollution.

Chinese food standards are similar to those in the US and elsewhere
China has been open about its air quality issues and food safety concerns. The country has been actively working on making its exports safer, with tons of regulations in place since 2015. China has implemented Hazards Analysis and Critical Control Points (HACCP) in the manufacturing sector, which is consistent with the practices used by Australia, New Zealand, Canada, and the US.
China has established extensive maximum residue limits (MRLs) for pesticides that the industry must adhere to for fresh food, including vegetables, fruits, eggs, and meat. However, limited coverage remains for processed food. In contrast, pesticide residue MRLs are well-established in fresh and processed food in Australia, New Zealand, the US, and Canada. For microbiological risk assessment, China, Australia, New Zealand, the US, and Canada use the Quantitative Microbiological Risk-Assessment system.
The US food safety system comprises the federal regulatory system and the state regulatory program. The major federal agencies are the Food and Drug Administration (FDA), the US Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS), the Environmental Protection Agency (EPA), and the National Marine Fisheries Service (NMFS). The FDA has jurisdictional authority over local and imported foods, excluding meat and poultry. The EPA is responsible for the licensing of all pesticide products, and NMFS conducts the assessment and grading of seafood.
China has also been working on improving food handlers' food safety knowledge, focusing on how poor food handling can negatively impact public health.
