Wu J. TB: draft reviewing, revision, and editing. Modern methods of grain cleaning have significantly reduced ergotism as a human disease; however, it is still an important veterinary problem. [46], The symptoms of mycotoxicosis depend on the type of mycotoxin; the concentration and length of exposure; as well as age, health, and sex of the exposed individual. Therefore, we need to pay more attention to the safety of dark tea during production and storage to ensure the health and safety of consumers. Dark tea has increased the risk of mycotoxins contamination due to the involvement of fungi during the microbial and hygrothermal dominated solid-state fermentation process. Vidal A., Mengelers M., Yang S., De Saeger S., De Boevre M. (2018). Identification and quantification of fungi and mycotoxins from pu-erh tea. Scientists continue to study why some strains of A. flavus are non-toxigenic and why the same strains produce very little toxin one year and deadly amounts another year. Hu L., Shi Z., Zhao L., Liu X., Dong Y., Jiang M., et al.. (2019). Numerous studies have indicated that the microorganisms play a significant part in the fermentation process of dark tea. OTA-producing fungi have similar strains to the dominant fungi in dark tea solid-state fermentation and storage As a result, there is a risk of OTA exposure during both the processing and storage of dark tea. It is also the direction of future efforts by dark tea producers. and transmitted securely. A., Sabino M. (2006). 2023 Jan 28;14(2):333. doi: 10.3390/mi14020333. If the sample pretreatment method is not appropriate and the interferences, such as tea pigment substances are not removed, the ELISA or HPLC assay will easily show false positives due to the interference of pigment substances. The fungi of the genus Fusarium mainly include Fusarium graminearum, Fusarium verticillioides, Fusarium nivale, Fusarium tricinctum, and Fusarium equiseti etc. and Penicillium spp. Overview of quality and safety standards for rice in China.

Received 2022 Dec 10; Accepted 2023 Feb 1. Climate change, food security and mycotoxins: do we know enough? The main manufacture processing of various dark tea. Toxic effects of AFB1, including growth suppression, malnutrition, and immunomodulation, are also covered. Bartosh AV, Sotnikov DV, Zherdev AV, Dzantiev BB. [28] Common Aspergillus spp. The ingestion of ergot sclerotia from infected cereals, commonly in the form of bread produced from contaminated flour, causes ergotism, the human disease historically known as St. Anthony's Fire. Lattanzio V. M. T., Visconti A., Haidukowski M., Pascale M. (2012). The General Multilevel Factorial Design (GMFD) method was employed to test the effect of ozone concentration and application time on the aflatoxin degradation process. fungi are dominant in the processing of dark tea, which is closely related to the formation of dark tea sensory quality (Wu J., 2013; Xiong, 2017). Quantitative analysis and dietary risk assessment of aflatoxins in Chinese post-fermented dark tea. The lawsuits took place after a study by the Center for Disease Control (CDC) in Cleveland, Ohio, reported an association between mycotoxins from Stachybotrys spores and pulmonary hemorrhage in infants. National Library of Medicine 2023 Jan 23;26(2):106051. doi: 10.1016/j.isci.2023.106051. [15] The synergistic effects associated with several other factors such as genetics, diet, and interactions with other toxins have been poorly studied. The toxicity of many masked mycotoxins may be much lower than their prototypes or even non-toxic, but if they react again in the human body, then there will be a greater safety risk. Discussion on the mechanism of quality and flavor formation of dark tea. Wang G., Wang Y., Zhang H., Zhang C., Yang B., Huang S., et al.. (2020). Vendl O., Crews C., Macdonald S., Krska R., Berthiller F. (2010). is also a pathogenic fungus, often causing mold in food, Mucor can enter the body through the respiratory tract, digestive tract, or skin, causing blood clots and tissue necrosis (Yang and Liu, 2021). Front Plant Sci. Unable to load your collection due to an error, Unable to load your delegates due to an error. Evaluation of the Adsorption Efficacy of Bentonite on Aflatoxin M. Current Developments of Analytical Methodologies for Aflatoxins' Determination in Food during the Last Decade (2013-2022), with a Particular Focus on Nuts and Nut Products. Most strains of Aspergillus parasiticus and some strains of Aspergillus nomius and Aspergillus niger have been found to also produce aflatoxin. The complexity of the tea matrix, the conversion of polyphenols to pigment substances such as theaflavins and thearubigins during the fermentation of dark tea by the action of moist heat and microbial extracellular enzymes (Jiang, 2012a; Zhang, 2015; Ji et al., 2016), which can affect the results of ELISA. The possible reasons for this situation are due to the results for ELISA are probably false positive, and LCMS/MS results seem more reliable. The main dominant microorganisms and potentially contaminating mycotoxins in dark tea are shown in Figure 1. Keywords: Two hundred and sixty strains of Penicillium spp. Mycotoxins are toxic fungal products that are produced when fungi grow in human and animal foods. Liu Y., Tan G., Liu Z., Li X., Chen J. 1996 Aug;5(8):613-9. government site. Aflatoxin is produced by the fungi Aspergillus and is one of the most potent hepatocarcinogenic substances known. The initial production process of dark tea can be roughly divided into fixing, rolling, pile fermentation, and drying. The kidney is the main target organ for the toxic effects of CIT, and there are also reports of CIT effects on the liver and bone marrow (Magan and Olsen, 2004). Development of an hplc-based method for the detection of aflatoxins in pu-erh tea, Wide caliber gas-chromatography to detect the content of t-2 toxin in grain. There are parts of fungi in the genus Aspergillus that produce mycotoxins, such as Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, and Aspergillus versicolor. from Liupao tea fermentation samples. [51] Most official regulations and control methods are based on high-performance liquid techniques (e.g., HPLC) through international bodies. There are many studies on mycotoxins in dark tea, and most of the findings suggest that the level of mycotoxin exposure in dark tea is insufficient to threaten the health of tea consumers (Liu et al., 2016; Mo et al., 2016; Hu et al., 2019). [41] It has been suggested that mycotoxins in stored animal feed are the cause of rare phenotypical sex changes in hens that causes them to look and act male. Clipboard, Search History, and several other advanced features are temporarily unavailable. The currently existing measuring methods of mycotoxins have trouble detecting the masked mycotoxins in dark tea (Tan et al., 2016). Snchez-Hervs M., Gil J. V., Bisbal F., Ramn D., Martnez-Culebras P. V. (2008). Citrinin is associated with yellowed rice disease in Japan and acts as a nephrotoxin in all animal species tested. Yang J., Zhao X., Zhang G., Guo J. Zhang Y., Skaar I., Sulyok M., Liu X., Rao M., Taylor J. W. (2016). Aflatoxins are mycotoxins produced by certain Aspergillus molds. A mycotoxin (from the Greek mykes, "fungus" and toxini, "toxin")[1][2] is a toxic secondary metabolite produced by organisms of kingdom Fungi[3][4] and is capable of causing disease and death in both humans and other animals. Several types of aflatoxins are produced naturally. WX and YZ: conceptualization, investigation, draft reviewing, and editing. However, ELISA may respond to masked mycotoxins (Berthiller et al., 2013). Zhou et al. An official website of the United States government. Medina ., Rodrguez A., Magan N. (2015). dark tea, mycotoxins, fungi, contamination, masked mycotoxins. Li and He (2020) examined 113 tea samples of Liupao tea from different years by HPLC, 37 positive CIT samples with a CIT content of 7.8206.1g/kg were detected. Bookshelf By means of enzymes (esterase, de-epoxidase), yeast (Trichosporon mycotoxinvorans), or bacterial strains (Eubacterium BBSH 797 developed by Biomin), mycotoxins can be reduced during pre-harvesting contamination. [48] To reverse the adverse effects of mycotoxins, the following criteria are used to evaluate the functionality of any binding additive: Since not all mycotoxins can be bound to such agents, the latest approach to mycotoxin control is mycotoxin deactivation. Therefore, it is possible that vitamin deficiency, caloric deprivation, excessive alcohol use, and infectious disease status can all have compounded effects with mycotoxins. They inhibit protein synthesis, damage macrophage systems, inhibit particle clearance of the lung, and increase sensitivity to bacterial endotoxin. Sriwattanapong K, Slocum SL, Chawanthayatham S, Fedeles BI, Egner PA, Groopman JD, Satayavivad J, Croy RG, Essigmann JM. In recent years, CIT has received much attention due to its toxic effects on mammals and its widespread presence in foods, where it is usually found together with OTAs (Silva et al., 2021). Ochratoxigenic fungi in post-fermented tea and inhibitory activities of, Not only pu-erh tea, all foods are at risk of aflatoxin contamination, Identification of fungal population in the pile fermentation process of kangzhuan tea. Contamination of feedstuffs as well as food commodities by fungi occurs frequently in a natural manner and is accompanied by the presence of mycotoxins. Ochratoxin (OTs) is a group of secondary metabolites produced by fungi Aspergillus and Penicillium (Wang et al., 2018). Therefore, the most effectively way to prevent dark tea from being contaminated by exogenous aflatoxin during processing and storage is an issue worthy of attention and consideration. The production of aflatoxin is not a requirement for the fungus to grow, reproduce and infect crops which is why aflatoxin is considered a secondary metabolite. [36][37] Numerous natural occurrences of mycotoxins in medicinal plants and herbal medicines have been reported[38][39] from various countries including Spain, China, Germany, India, Turkey and from the Middle East. (2022). The results of mycotoxin detection in dark tea are inconsistent due to different sources of dark tea samples as well as different methods of determination. Yang J., Zeng X., Pu H., Yang X., He Z. [23] Stachybotrys chartarum contains a higher number of mycotoxins than other molds grown in the indoor environment and has been associated with allergies and respiratory inflammation. On the other hand, Fungi of the genus Penicillium have been detected during the storage of dark tea (Haas et al., 2013). A preliminary research on separation and identification of the fungi form xiang-yi fuzhuan tea. Buildings are another source of mycotoxins and people living or working in areas with mold increase their chances of adverse health effects. In Lis finding, total of 218 fungi was isolated from Liupao tea, and some of these strains, such as Aspergillus ochraceus, Aspergillus oryzae, Penicillium citrinum, and Penicillium chrysogenum can produce CIT (Li et al., 2020). Pharmacol Ther. (2021). (2020) examined 158 dark tea samples by liquid chromatography-mass spectrometry, two of which tested positive for aflatoxins. Contamination can take place both pre- and post-harvest. (2012) isolated Mucor spp. Aspergillus spp. sharing sensitive information, make sure youre on a federal Kluger B., Bueschl C., Lemmens M., Michlmayr H., Malachova A., Koutnik A., et al.. (2015). Zhao et al. That's pretty alarming since they largely affect food staples like corn. Regarding detoxification methods, chemical control methods were the fastest methods that still retained high detoxification efficacy. CIT is a well-known hepatorenal toxin that causes functional and structural kidney damage as well as debilitation of liver metabolism (Flajs and Peraica, 2009; Vidal et al., 2018). In summary, many researchers have isolated and identified the microorganisms from dark tea. Aflatoxin G 1 is also highly toxic and carcinogenic in certain animal models. Palacios S. A., Erazo J. G., Ciasca B., Lattanzio V. M. T., Reynoso M. M., Farnochi M. C., et al.. (2017). Some of the mycotoxins in the indoor environment are produced by Alternaria, Aspergillus (multiple forms), Penicillium, and Stachybotrys. (2003). Cellular interactions and metabolism of aflatoxin: an update. Andersen B., Smedsgaard J., Frisvad J. C. (2004). (2021) and Zhou et al. Wu et al. The change of the inner material component of dark tea is intimately related to temperature, humidity, and age (Chen Y. et al., 2016).

[30], Dimorphic fungi, which include Blastomyces dermatitidis and Paracoccidioides brasiliensis, are known causative agents of endemic systemic mycoses. Aflatoxin can affect a wide range of food commodities including corns, oilseeds, spices, and tree nuts as well as milk, meat, and dried fruit. Would you like email updates of new search results? Mycotoxins widely existed in all kinds of food, which is a serious threat to human health and safety, which has become one of the most important issues in the field of food safety (Bhat et al., 2010; Medina et al., 2015, 2017; Haque et al., 2020; Martnez-Culebras et al., 2021; Zhang et al., 2021). (2021). [15], Mycotoxins greatly resist decomposition or being broken down in digestion, so they remain in the food chain in meat and dairy products. LCMS/MS can simultaneously detect different components in mixed samples, so that masked mycotoxins, their prototypes, metabolites, and even different types of mycotoxins can be quantified simultaneously. Aflatoxins belong to a class of compounds known as mycotoxins. Dark tea is a kind of post-fermented tea with the characteristic that flavor improves with ages, and its flavor is unique. Annu Rev Phytopathol. Aflatoxin is a cancer-causing poison produced by certain fungi in or on foods and feeds, especially in field corn and peanuts. (2015a,b) isolated an OTA-producing Penicillium chrysogenum dominant strain from Pu-erh tea by inoculating it on raw dark tea with 35% moisture content at 30C for 25days, and the CIT content was 26.30g/kg. 2023 Feb 15;9(2):261. doi: 10.3390/jof9020261. Aflatoxin is a potent carcinogen that is highly regulated in most countries. Stachybotrys spores in animal studies have been shown to cause lung hemorrhaging, but only at very high concentrations.

Aflatoxin; Detoxification; Exposure; Hepatocellular carcinoma; Metabolism; Toxicity. Effect and advances in research of deoxynivalenol on intestinal health of livestock and poultry. Zhao et al. Aspergillus species can produce aflatoxins (AFs), which can severely affect human and animal health. The .gov means its official. Due to the shortage of commercial standards, studies on the quantitative analysis of masked mycotoxins are significantly limited. CIT is a fungal toxin widely present in food, and there is a possibility that dark tea is contaminated with CIT. Iqbal S. Z., Nisar S., Asi M. R., Jinap S. (2014). Polyketides as Secondary Metabolites from the Genus, Evaluation of Agronomic Characteristics, Disease Incidence, Yield Performance, and Aflatoxin Accumulation among Six Peanut Varieties (, Low-dose ethanol increases aflatoxin production due to the, Putative Core Transcription Factors Affecting Virulence in, Impact of Volatile Organic Compounds on the Growth of. Aflatoxins are mycotoxins produced by some fungi found on agricultural crops like peanuts, cottonseed, tree nuts, and maize (corn). The site is secure. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Mycotoxins are regarded as the main contributor to the quality of dark tea, and its potential mycotoxin risk has attracted peoples attention. Aflatoxins (AFTs) are a class of secondary metabolites produced by Aspergillus parasiticus and Aspergillus flavus (Piekkola et al., 2012). Many researchers have tested OTA in dark tea using various testing techniques, and the results are detailed in Table 2. Murugesan G. R., Ledoux D. R., Naehrer K., Berthiller F., Applegate T. J., Grenier B., et al.. (2015). Its necessary to constantly pay attention to the changes in environmental conditions during the storage of dark tea to prevent it from being contaminated by fungi during the storage process. They consume organic matter wherever humidity and temperature are sufficient. 62 The production of aflatoxin is dependent on the fungi's access to O 2, CO 2, zinc, and copper. FOIA Taxonomy: Chai Y., Cui C., Li C., Wu C., Tian C., Hua W. (2012). Complementary DNA Significantly Enhancing Signal Response and Sensitivity of a Molecular Beacon Probe to Aflatoxin B1.

This review focuses on the metabolism of AFB1, including epoxidation and DNA adduction, as it concerns the initiation of cancer and the underlying mechanisms. Occurrence of toxigenic fungi and determination of mycotoxins by hplc-fld in functional foods and spices in China markets. Since the majority of OTA-producing fungi can produce CIT (Silva et al., 2021), OTA was also detected in many tea samples, which forced us to consider whether OTA-producing fungi in dark tea will also produce CIT. Many researchers have isolated and identified the dominant microorganisms from the production and processing of dark tea as well as from the finished tea, and the more common dominant microbial genera are shown in Table 4. [29], Physical methods to prevent growth of mycotoxinproducing fungi or remove toxins from contaminated food include temperature and humidity control, irradiation and photodynamic treatment. Epub 2022 Jan 11. Recent evidence suggests that mycotoxins were detected in fermented tea (Liu et al., 2016; Mo et al., 2016; Hu et al., 2019; Xu W. et al., 2019), which indicated that there is indeed a possibility that dark tea is contaminated with mycotoxins during the production and processing as well as storage processes. [10][11], Ochratoxin is a mycotoxin that comes in three secondary metabolite forms, A, B, and C. All are produced by Penicillium and Aspergillus species. Li W., Xu K., Xiao R., Yin G., Liu W. (2015). [9], Aflatoxins are a type of mycotoxin produced by Aspergillus species of fungi, such as A. flavus and A. Wang Y., Wang L., Wu F., Liu F., Wang Q., Zhang X., et al.. (2018). (Zu et al., 2021). Lozowicka B., Iwaniuk P., Konecki R., Kaczynski P., Kuldybayev N., Dutbayev Y. Liu et al. [16] In 2004, the European Community set limits to the concentrations of patulin in food products. [51] However, one must take note that scientific risk assessment is commonly influenced by culture and politics, which, in turn, will affect trade regulations of mycotoxins. In such cases the distinction is based on the size of the producing fungus and human intention. The occurrence of mycotoxins in breast milk, fruit products and cereal-based infant formula: a review, Mycotoxins and mould contamination in cheese: a review. During processing, high temperature and high humidity conditions are favorable for microbial growth and the metabolic transformation of black tea, but if the dark tea is contaminated with harmful fungi during the pile fermentation, then there is a risk that the dark tea will be contaminated with fungal toxins. Haas D., Pfeifer B., Reiterich C., Partenheimer R., Reck B., Buzina W. (2013). official website and that any information you provide is encrypted sharing sensitive information, make sure youre on a federal Aflatoxin, a food contaminant produced by the fungi Aspergillus flavus and Aspergillus parasiticus, is a known human carcinogen that has been shown to be a causative agent in the pathogenesis of HCC. Aflatoxins (AFTs) are a class of secondary metabolites produced by Aspergillus parasiticus and Aspergillus flavus (Piekkola et al., 2012).Aflatoxins are readily produced by Aspergillus flavus under relatively high air humidity and temperature conditions (Yu et al., 2004).Aflatoxins can be classified into several types, such as B 1, B 2, G 1, and G 2. Therefore, it is necessary to conduct basic research on the formation, regulatory mechanisms, contamination status, and detection methods of the major masked mycotoxins in tea to provide a scientific basis for effective prevention, control, and safety supervision of masked mycotoxins in tea. Vendl et al. The results of some reports have shown that some of the masked mycotoxins may re-release their prototypes after entering the digestive systems of humans and animals, posing serious potential safety hazards to food. Existing microbial studies on dark tea have identified Aspergillus spp. There exist several methods for measuring the mycotoxins, for instance: thin-layer chromatography (TIC)(Zhao et al., 2016), enzyme-linked immunosorbent assay (ELISA)(Li et al., 2016; Zhang, 2017; Zhu et al., 2017), high performance liquid chromatography (HPLC) (Kong et al., 2014; Li and He, 2020; Iqbal et al., 2021), liquid chromatographytandem mass spectrometry (LCMS/MS) (Kresse et al., 2019; York et al., 2020), and gas chromatography (GC) (Li et al., 2000; Lin et al., 2013). RNA interference-based silencing of the alpha-amylase (amy1) gene in Aspergillus flavus decreases fungal growth and aflatoxin production in maize kernels. [18][19] They include a range of mycotoxins, such as: the fumonisins, which affect the nervous systems of horses and may cause cancer in rodents; the trichothecenes, which are most strongly associated with chronic and fatal toxic effects in animals and humans; and zearalenone, which is not correlated to any fatal toxic effects in animals or humans. [31], There were outbreaks of dog food containing aflatoxin in North America in late 2005 and early 2006,[32] and again in late 2011. An official website of the United States government. Hu Z., Liu S., Xu Z., Liu S., Wen X. and transmitted securely. There are only a few reports on the preparation of standards, anabolic pathways of masked mycotoxins (Tan et al., 2016), which is the reason that masked mycotoxins deserve further attention and research. [15], Ergot alkaloids are compounds produced as a toxic mixture of alkaloids in the sclerotia of species of Claviceps, which are common pathogens of various grass species. (2013) used HPLC to detect AFB1 in seven samples at concentrations greater than 5g/kg in 60 samples of Pu-erh tea. Currently, commonly used direct detection methods include LCMS/MS and ELISA. Aspergillus flavus, which often is shortened to A. flavus, produces aflatoxins, though the fungus doesn't need to make the toxin to survive. [8] Because mycotoxins weaken the receiving host, they may improve the environment for further fungal proliferation. He S., Li H., Li B., Han X., Jiang H., Jin Y., et al..

As can be seen from Table 4, fungi of the genera Aspergillus and Penicillium play a very significant role in the processing of dark tea. Factors that affect the formation of mycotoxins: a literature review. Aspergillus flavus, which often is shortened to A. flavus, produces aflatoxins, though the fungus doesnt need to make the toxin to survive. Some of these species are used to produce human foodstuffs such as cheese (Penicillium camemberti), sake, miso, and soy sauce (Aspergillus oryzae). Zhou H., Li J., Zhao L., Han J., Yang X., Yang W., et al.. (2004). The mycotoxins detection studies in tea, where results of the test by ELISA were mostly positive for mycotoxins (Santos et al., 2009; Liu, 2011), also forced us to think, whether there are also masked mycotoxins in tea. BMC Bioinformatics. Li (2019) isolated fungi of the genus Rhizoctonia from Yaan Tibetan Tea. Bai X, Sheng Y, Tang Z, Pan J, Wang S, Tang B, Zhou T, Shi L, Zhang H. J Fungi (Basel). Aflatoxins can be found in foodstuffs contaminated with aflatoxin-producing Aspergillus or in dairy milk from animals fed contaminated feed. Difficulties in fumonisin determination: the issue of hidden fumonisins. Formed during growth of these fungi on commodities such as cereals (e.g. However, the amount of aflatoxin the fungus produces varies wildly.

Accessibility Mycotoxins have the potential for both acute and chronic health effects via ingestion, skin contact,[45] inhalation, and entering the blood stream and lymphatic system. There are more than 600 species of fungi in the genus Penicillium, and their morphological characteristics are generally similar to each other. National Library of Medicine Kim E. K., Scott P. M., Lau B. P. Y. This study reviews common and potential mycotoxins in dark tea and discusses the possible types of masked mycotoxins in dark tea. Current role of modern chromatography and mass spectrometry in the analysis of mycotoxins in food. Several types of aflatoxins exist, but food contamination usually involves aflatoxins B1, B2, G1, and G2 for crops and M1 for milk. Isolation and identification of preponderant strains of fu brick tea and primary study on fermentation of low grade green tea. DON is potentially harmful to both humans and animals when it enters the food chain, such as causing loss of appetite, immunosuppression, nausea, and vomiting, and has been classified as a Class III carcinogen by the European Union (Pereira et al., 2019). It also is a pathogen of animals and insects. It is an extremely common soil fungus. Chemistry and biology of mycotoxins and related fungal metabolites. This site needs JavaScript to work properly. Some of the other major types of Fusarium toxins include: enniatins such as beauvericin), butenolide, equisetin, and fusarins. (1965). [36] In a 2015 analysis of plant-based dietary supplements, the highest mycotoxin concentrations were found in milk thistle-based supplements, at up to 37mg/kg.
