Chinese mushrooms and arsenic
Arsenic is a natural environmental contaminant that humans are usually exposed to in water, air, soil, and food. China is a high-arsenic region, and it contributed more than 70% of the world's production of cultivated, edible mushrooms in 2016.
Fungi can accumulate varying amounts of arsenic and different arsenic compounds in their fruiting bodies (mushrooms) due to arsenic-resistant proteins. This has raised concerns about the arsenic content of edible mushrooms and the potential health risks of consuming mushrooms with elevated arsenic levels.
Several studies have investigated arsenic species and their concentrations in mushrooms from China. The extraction efficiency of arsenic species from mushrooms in these studies ranged from 55.3% to 104%. The presence of arsenic in mushrooms is influenced by factors such as the mushroom species, the concentration of arsenic in the soil, and the age of the mushroom.
Health risk assessments of arsenic in mushrooms from China have been conducted, comparing total arsenic levels with maximum permitted thresholds. According to China's National Standard for Food Safety, the maximum allowed arsenic level in edible plants and fungi is 0.5 mg/kg fresh weight.
It is important to note that the presence of arsenic in mushrooms is not limited to those from China. Arsenic hyperaccumulation has been observed in mushrooms worldwide, and studies have detected various arsenic species in mushrooms from different regions.

Cancer-causing pollution in Chinese mushrooms
While some sources suggest that Chinese mushrooms may be laced with cancer-causing pollution, it is important to examine the facts and evidence behind these claims.
Firstly, it is crucial to understand that China is a major producer of cultivated, edible mushrooms, contributing more than 70% of the world's supply in 2016. With such a significant market share, the safety of Chinese mushrooms is a valid concern for consumers.
One of the primary concerns regarding Chinese mushrooms is the presence of arsenic (As). Arsenic is a natural environmental contaminant found in water, air, soil, and food. China is known to have high levels of arsenic in its environment, and this has raised questions about the safety of edible mushrooms grown in the country. Some studies have indeed found elevated levels of arsenic in Chinese mushrooms, particularly in certain regions with biogeochemical anomalies of arsenic in soils or sediments, such as Gejiu, Lincang, and Tengchong.
Additionally, there have been reports of illegal pesticide residue found in imported Chinese mushrooms, particularly in canned and fresh shiitake mushrooms. This is concerning as pesticides can have harmful effects on human health, including potential carcinogenic properties.
However, it is important to consider the regulatory standards in place. China has its own National Standard for Food Safety, which sets maximum permitted levels of contaminants like arsenic in edible plants and fungi. While the standards may differ from those in other countries, they do provide a framework for ensuring food safety. Furthermore, the punishment for failing to comply with food safety standards in China can be harsh, indicating a level of seriousness in addressing these concerns.
It is also worth noting that the association between mushroom consumption and cancer risk is complex. While some sources express concern about cancer-causing pollution in Chinese mushrooms, other studies suggest that higher mushroom consumption may be associated with a lower risk of certain cancers, including breast cancer. This indicates that mushrooms may have potential anticancer effects, and medicinal mushrooms have been used as a complementary treatment for cancer patients in China and other Asian countries for many years.
In conclusion, while there are valid concerns about the presence of contaminants like arsenic and illegal pesticides in Chinese mushrooms, it is important to consider the regulatory standards in place and the potential health benefits associated with mushroom consumption. The claims of cancer-causing pollution in Chinese mushrooms may be overstated, and more research is needed to fully understand the complex relationship between mushroom intake and cancer risk. Consumers should make informed decisions based on the available evidence and their own comfort levels.

Chinese food safety standards
Food safety in China has been a cause for concern for consumers and the agricultural industry. In 2007, a report by the Asian Development Bank in collaboration with the State Food and Drug Administration and the World Health Organization applauded the Chinese government's efforts but called for urgent reforms. In response, China approved new legislation to improve and monitor national standards in food production.
The Food Safety Law of the People's Republic of China came into effect on 1 June 2009 and became the major food safety protection law. This legislation outlines the responsibilities of the Ministry of Health, including risk assessment, formulating food safety standards, and disseminating information. The Ministry of Science and Technology (MST) also plays a crucial role in regulating market product quality, inspecting products, and enforcing penalties for violations.
To address the concerns, China has a myriad of relevant laws, regulations, and rules in place. These include the PRC Food Hygiene Law, PRC Product Quality Law, PRC Agricultural Product Quality Safety Law, and the PRC Consumer Rights Protection Law. The National Institute of Nutrition and Food Safety (NINFS), affiliated with the Chinese Center for Disease Control and Prevention, works to improve nutritional status, prevent foodborne diseases, and enhance the physical fitness of the population.
In recent years, there have been amendments to the Food Safety Law to strengthen food safety supervision further. The Second Revised Amendment, published in December 2014, incorporates public views and suggestions, focusing more on consumer rights and operator behaviour. It includes frameworks for online food trading regulations, mandatory food safety liability insurance, and enhanced penalties for violations. These amendments encourage regulation from non-governmental stakeholders and promote a reporting system where anyone can report alleged food safety violations.

Chinese mushroom poisoning
Chinese mushrooms have been found to be unsafe for consumption due to the presence of illegal pesticide residue and arsenic. China contributed more than 70% of the world's production of cultivated, edible mushrooms in 2016. However, the sale and consumption of these mushrooms have raised concerns due to the potential health risks associated with them.
Mushroom poisoning has emerged as a significant food safety concern in China and has become a serious public health problem that threatens human life and health safety. It is the primary foodborne disease causative factor and the cause of the most related deaths in the country. The poisoning has noticeable seasonal and regional characteristics, with the season of abundant rainfall being the high-incidence period and rural households being the main place of occurrence, with the highest case fatality rate.
Several species of poisonous mushrooms have been identified in China, with Chlorophyllum molybdites, Entoloma omiense, and Russula japonica being the most commonly encountered. In addition, some species of mushrooms have been found to contain toxic elements such as arsenic, which can accumulate in the fruiting bodies of the mushrooms due to the presence of certain proteins in the fungi. The total arsenic content in mushrooms from China has been compared with the maximum permitted levels from different standards, and health risk assessments have been carried out to ensure food safety.
To address the issue of mushroom poisoning, the Chinese government, CDCs, hospitals, and mycological researchers have collaborated to establish a comprehensive network for collecting information, facilitating diagnosis, and providing treatment support. This network utilizes various communication methods such as WeChat, telephone, and email. In addition, there is a focus on promoting prevention and improving the ability of professionals to identify, diagnose, and treat mushroom poisoning. Educational materials on toxic mushrooms are also being developed and disseminated to reach a wider audience and reduce the incidence of mushroom poisoning.

Imported Chinese mushrooms and pesticides
Imported Chinese mushrooms have been found to contain illegal pesticide residue. While most Chinese mushrooms are canned, fresh mushrooms are increasingly being exported to foreign markets, especially shiitake mushrooms. A study on the dissipation of pesticides in mushrooms found that the pesticides beta-cypermethrin, pyriproxyfen, avermectin, and diflubenzuron were present in oyster and shiitake mushrooms after 90 days of application. The study evaluated the dissipation of pesticides using two different treatments: substrate mixture and surface spraying. The dissipation of pesticides was found to be faster with surface spraying, with the dissipation of beta-cypermethrin, pyriproxyfen, and diflubenzuron being below their MRLs in China and Japan within 7 days.
China is a major producer of edible mushrooms, contributing more than 70% of the world's production of cultivated edible mushrooms in 2016. However, there have been concerns about the presence of toxic elements, such as arsenic, in Chinese mushrooms. Arsenic is a natural environmental contaminant that humans are typically exposed to in water, air, soil, and food. Some studies have found that mushrooms from specific regions in China, such as Yunnan, may contain elevated levels of arsenic due to biogeochemical anomalies in the soil.
The National Standard for Food Safety in China sets the maximum permitted levels of total arsenic in edible plants and fungi at 0.5 mg/kg fresh weight. Health risk assessments of arsenic in mushrooms from China have been conducted in several studies, comparing the total arsenic content with the maximum permitted levels from different standards. However, the safety of Chinese mushrooms has been questioned due to concerns about food safety standards in the country. There have been several food scandals in China, including incidents of food being tainted with harmful chemicals and pesticides.
While there are concerns about the safety of imported Chinese mushrooms, it is important to consider the role of xenophobia and racism in shaping perceptions of food safety. Some argue that warnings about Chinese mushrooms are based on xenophobic sentiments rather than scientific evidence. Additionally, it is worth noting that food production standards in developing countries may differ from those in developed countries, and the presence of contaminants in low amounts may not necessarily pose a significant health risk.
