Some of the mycotoxins in the indoor environment are produced by Alternaria, Aspergillus (multiple forms), Penicillium, and Stachybotrys. WX and YZ: conceptualization, investigation, draft reviewing, and editing. Therefore, during the storage process, dark tea is always changing silently, and the degree is accountable for the storage conditions. These fungi may produce toxic secondary metabolites such as trichothecenes, zearalenone, moniliformin, and butenolide (Huang et al., 2017). Gilbert MK, Majumdar R, Rajasekaran K, Chen ZY, Wei Q, Sickler CM, Lebar MD, Cary JW, Frame BR, Wang K. Planta. The main fungi that produce aflatoxin are Aspergillus flavvus. have an essential contribution to the quality formation of dark tea. Yan (2019) examined 61 fermented dark tea samples, and DON was detected in three samples, including one Pu-erh tea with 8.6g/kg and two Hunan dark tea with 70.1 and 299.5g/kg, respectively. Zhou et al. Mo J., Gong Q., Zhou H., Bai X., Tan J., Peng Z., et al.. (2016). 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. Mycotoxins are toxic substances produced by fungi (mycotoxigenic fungi) on the different substrates where they grow. Climate change, food security and mycotoxins: do we know enough? Most masked mycotoxins are less toxic or non-toxic than their original mycotoxins. There are four main types of aflatoxins: B1, B2, G1, and G2. Aflatoxin B1 (AFB1) is the most potent of these compounds and has been well-characterized to lead to the development of hepatocellular carcinoma (H He S., Li H., Li B., Han X., Jiang H., Jin Y., et al.. (2020). This paper reviews the contamination status and contamination levels of common mycotoxin species in dark tea, also speculates on the masked mycotoxins that may exist in dark tea, and discusses the main microbial sources of mycotoxin production in dark tea and the possible ways to cause mycotoxin contamination processes in dark tea, which may provide a reference for food safety policymakers and researchers. Furukawa T, Kushiro M, Nakagawa H, Enomoto H, Sakuda S. iScience. Tirmenstein, R. Mangipudy, in Encyclopedia of Toxicology (Third Edition), 2014 Abstract Evaluation of mycoflora and citrinin occurrence in chinese liupao tea. Vendl O., Crews C., Macdonald S., Krska R., Berthiller F. (2010). Lpez P., Venema D., de Rijk T., de Kok A., Scholten J. M., Mol H. G. J., et al.. (2016). [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. TB: draft reviewing, revision, and editing. 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. FOIA Currently, over 100 countries have regulations regarding mycotoxins in the feed industry, in which 13 mycotoxins or groups of mycotoxins are of concern. [12] Aspergillus ochraceus is found as a contaminant of a wide range of commodities including beverages such as beer and wine. (2021) isolated 560 fungal strains from dark tea samples, including seven species of Penicillium spp. The major molds which make aflatoxins including Aspergillus . Citrinin in foods and supplements: a review of occurrence and analytical methodologies, Fungal Solid-State Fermentation Teas and Its Teadenol-Producing Potentiality, Major types of masked mycotoxins and state-of-the-art methodological advance for their detection. And Zhao Z. et al. Yang J., Zeng X., Pu H., Yang X., He Z. [10] Aflatoxins are largely associated with commodities produced in the tropics and subtropics, such as cotton, peanuts, spices, pistachios, and maize. Furthermore, a summary of recent detoxification methods is included to indicate the present state of the field in developing aflatoxin control methods. In such cases the distinction is based on the size of the producing fungus and human intention. [15], Mycotoxins greatly resist decomposition or being broken down in digestion, so they remain in the food chain in meat and dairy products. Different kinds of dark tea have been found to have their own dominant fungal strains during the processes of fermentation and storage (Xiong, 2017), and parts of these strains can synthesize fungal toxins. Modern methods of grain cleaning have significantly reduced ergotism as a human disease; however, it is still an important veterinary problem. On the other hand, Fungi of the genus Penicillium have been detected during the storage of dark tea (Haas et al., 2013). [15], Patulin is a toxin produced by the P. expansum, Aspergillus, Penicillium, and Paecilomyces fungal species. Mycotoxins are toxic fungal products that are produced when fungi grow in human and animal foods. The negative health effects of mycotoxins are a function of the concentration, the duration of exposure, and the subject's sensitivities. Pharmacol Ther. [42][43] Mycotoxins impact on health may be "very hard" and can be categorized in three forms "as mutagenic, carcinogenic, and genotoxic. A series of complex transformations occur to form the unique flavor quality of dark tea (Wang et al., 1991a). In the 1990s, public concern over mycotoxins increased following multimillion-dollar toxic mold settlements. The major concern with this fungus in agriculture is that it produces highly carcinogenic toxins called aflatoxins which are a health hazard to animals. Over 25% of the samples . Federal government websites often end in .gov or .mil. Wu et al. Although only a few Aspergillus niger fungi are able to produce mycotoxins, we absolutely need to pay more attention to them. Dark tea has the quality of The unique flavor grows over time, but unscientific storage of dark tea might cause infestation of harmful microorganisms, thereby resulting in the remaining of fungi toxins. Hamad GM, El-Makarem HSA, Allam MG, El Okle OS, El-Toukhy MI, Mehany T, El-Halmouch Y, Abushaala MMF, Saad MS, Korma SA, Ibrahim SA, Hafez EE, Amer A, Ali E. Toxins (Basel). Unable to load your collection due to an error, Unable to load your delegates due to an error. In Senegal, groundnut and maize are commonly contaminated with highly toxic, cancer-causing chemicals called aflatoxins, which are produced by fungi in the genus Aspergillus when they infect crops. [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. Occurrence of alternaria toxins in food products in the Netherlands. fumeus, Aspergillus penicillioides, Aspergillus aureolatus, Aspergillus egyptiacus, Aspergillus foetidus, Aspergillus japonicus Saito var. Accessibility Aflatoxin is produced by the fungi Aspergillus and is one of the most potent hepatocarcinogenic substances known. Ochratoxin a producing fungi, biosynthetic pathway and regulatory mechanisms. The site is secure. These compliance programs sample food products including peanuts and peanut products, tree nuts, corn and corn products, cottonseed, and milk. They are probably the best . Accessibility (2009) isolated Aspergillus niger, Aspergillus tamarii, Aspergillus fumigatus, Aspergillus clavatus, Aspergillus oryzae, Aspergillus glaucus, Aspergillus terreus, Aspergillus candidus, Aspergillus wentii var. Separation and purification of deoxynivalenol (don) mycotoxin from wheat culture using a simple two-step silica gel column chromatography. OTA has been found in black and green tea samples, according to some studies (Santos et al., 2009; Malir et al., 2014). Li Z., Mao Y., Teng J., Xia N., Huang L., Wei B., et al.. (2020). The General Multilevel Factorial Design (GMFD) method was employed to test the effect of ozone concentration and application time on the aflatoxin degradation process. (2012) isolated Aspergillus niger, Aspergillus oryzae, and Aspergillus glaucus from Liupao tea fermentation samples. (2021) isolated Fusarium equiseti, Alternaria, and Cladosporium cladosporioides from Fuzhuan tea. Although DON is mostly detected in cereals and their products, the researchers have not paid sufficient attention to it. In the field, A. flavus is predominantly a problem in the oilseed crops maize, peanuts, cottonseed and tree nuts. Determination of ochratoxin a in pu-erh tea by ultra performance liquid chromatography-tandem mass spectrometry. LCMS/MS method has been widely used for the detection of mycotoxin residues in cereals, grains, oils, and other foods for its high selectivity and sensitivity (Lozowicka et al., 2022). National Library of Medicine soybeans). fungi can produce a variety of fungal toxins, such as: aflatoxin, ochratoxin, citrinin, and vomitoxin (Sengun et al., 2008; Brse et al., 2009; Zhao et al., 2017; Li et al., 2021). (2013) isolated and identified two strains of Penicillium citrinum from traditional Pu-erh tea loose tea, three strains in organic Pu-erh tea loose tea, and three strains in tightly pressed Pu-erh tea, respectively. Bethesda, MD 20894, Web Policies Cui Y, Wang Q, Zhang X, Yang X, Shi Y, Li Y, Song M. Foods. The site is secure. Deoxynivalenol: insights on genetics, analytical methods and occurrence. [51] It is implied that any regulations regarding these toxins will be in co-ordinance with any other countries with which a trade agreement exists. They found that Stachybotrys is possibly an important contributing factor to DBRI. Unauthorized use of these marks is strictly prohibited. (2013). Another possible reason is that the mycotoxins in tea transform themselves or combine with certain substances in tea to form masked mycotoxins that are difficult to detect. 2011;49:107-33. doi: 10.1146/annurev-phyto-072910-095221. [13] OTA has been labeled as a carcinogen and a nephrotoxin, and has been linked to tumors in the human urinary tract, although research in humans is limited by confounding factors. Dark tea is a kind of post-fermented tea with the characteristic that flavor improves with ages, and its flavor is unique. Natural incidence of aflatoxins, ochratoxin a and zearalenone in chicken meat and eggs. 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. 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. Mycobiota and mycotoxin producing fungi from cocoa beans. Pereira L. T. P., Putnik P., Iwase C. H. T., de Oliveira Rocha L. (2019). Aflatoxins are produced primarily by the fungi Aspergillus flavus and Aspergillus parasiticus. Aspergillus flavus, which often is shortened to A. flavus, produces aflatoxins, though the fungus doesn't need to make the toxin to survive. 2023 Jan 14;9(1):118. doi: 10.3390/jof9010118. Before Numerous studies have indicated that the microorganisms play a significant part in the fermentation process of dark tea. Although dark tea has the characteristic of flavor improves with ages, if it is not stored properly, it may becomeinfested with harmful fungi and thus become moldy or produce fungal toxins that are harmful to human health. [40], Some of the health effects found in animals and humans include death, identifiable diseases or health problems, weakened immune systems without specificity to a toxin, and as allergens or irritants. (2015). Currently, commonly used direct detection methods include LCMS/MS and ELISA. Recent findings indicate that lower doses (studies usually involve high doses) can cause these symptoms. 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). (2003). (2019). The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Zhang J., Xia Z., Zhang X., Zheng D., Zhou Y. 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. Screening of mycotoxin multicontamination in medicinal and aromatic herbs sampled in Spain, Deoxynivalenol fatty acid and glucoside conjugates. Medina A., Akbar A., Baazeem A., Rodriguez A., Magan N. (2017). Snchez-Hervs M., Gil J. V., Bisbal F., Ramn D., Martnez-Culebras P. V. (2008). Li H., Tan Y., Chen Z., Qu J., Chen Y., Fang X. 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).

The https:// ensures that you are connecting to the 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. Mycotoxins are secondary metabolites produced by fungi that may be harmful to humans when ingested, inhaled, or in contact with skin (Marin et al., 2013). Among them, aflatoxin B1 (AFB1) is the most toxic and has been classified as a class I carcinogen by the World Health Organization Cancer Research Unit (Yogendrarajah et al., 2015). Kresse M., Drinda H., Romanotto A., Speer K. (2019). [15] Mycotoxin exposure is almost always accidental whereas with mushrooms improper identification and ingestion causing mushroom poisoning is commonly the case. Santos L., Marn S., Sanchis V., Ramos A. J. Whether it forms masked mycotoxins in the same condition. It is urgent to perform a precise screening of beneficial microorganisms and avoid harmful microbial infestation, which is also an effective way to prevent fungal toxin contamination in dark tea. fungi in dark tea. (2020) examined 158 dark tea samples by liquid chromatography-mass spectrometry, two of which tested positive for aflatoxins. Aspergillus species can produce aflatoxins (AFs), which can severely affect human and animal health. In summary, many researchers have isolated and identified the microorganisms from dark tea. fungi are the dominant species in the production and processing of dark tea and have a strong relationship with the formation of dark tea quality (Jiang, 2012a; Wu J., 2013; Xiong, 2017). It is an extremely common soil fungus. Bartosh AV, Sotnikov DV, Zherdev AV, Dzantiev BB. 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. The standardized of the production of dark tea is urgently needed to ensure the safety of the dark tea production, processing, and storage environments, which is the guarantee for the prosperous development of the dark tea industry. Zhao et al. Isolation and identification of dominant microorganisms of liupao tea before and after steaming. [16][17] It is destroyed by the fermentation process and so is not found in apple beverages, such as cider. Simultaneous detection and analysis of 16 kinds of mycotoxins in pu-erh tea. Whether the masked mycotoxins are harmful to consumers. Toxicol Sci. Molds growing in buildings can be divided into three groups primary, secondary, and tertiary colonizers. Kim E. K., Scott P. M., Lau B. P. Y. 1997 Aug;31(4):417-24. doi: 10.1590/s0034-89101997000400011. 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. Determination of ochratoxin a in tea by high performance liquid chromatography-tandem mass spectrometry. [25] Testing for mycotoxicosis can be conducted using immunoaffinity columns. The dominant strains in dark tea during the solid-state fermentation process are similar to many OTA-producing strains, but OTA is not only present in dark tea samples. Bugno A., Almodovar A. 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). Please enter your credentials below. Microorganisms in dark tea play an important part in the formation of dark tea sensory quality, while some microorganisms can lead to tea fungal toxin contamination (Xin and Liang, 2020). Under the right conditions, the fungus will grow and produce aflatoxin in almost any stored crop seed. government site. Wang Z., Shi Z., Liu Z., Huang J., Wen Q. A summary of the potential risks of mycotoxins and masked mycotoxins in dark tea is presented, intending to provide a reference for the prevention and risk assessment of harmful fungi in dark tea. Many Aspergillus spp. Contamination can take place both pre- and post-harvest. Registration confirmation will be emailed to you. The secondary metabolites produced by fungi known as mycotoxins, are capable of causing mycotoxicosis (diseases and death) in human and animals. Development and validation of an lc-ms/ms method for the simultaneous determination of deoxynivalenol, zearalenone, t-2-toxin and some masked metabolites in different cereals and cereal-derived food. 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 can be found in foodstuffs contaminated with aflatoxin-producing Aspergillus or in dairy milk from animals fed contaminated feed. On-line sample preparation for multiclass vitamin, hormone, and mycotoxin determination in chicken egg yolk using lc-ms/ms. affected by mycotoxins, of which the most notorious are aflatoxins. Wang Z., Shi Z., Liu Z., Huang J., Shi L., Wen Q., et al.. (1991a). 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. They currently stand at 50 g/kg in all fruit juice concentrations, at 25 g/kg in solid apple products used for direct consumption, and at 10 g/kg for children's apple products, including apple juice. were able to produce CIT. CIT is a fungal toxin widely present in food, and there is a possibility that dark tea is contaminated with CIT. Berthiller F., Dall'Asta C., Schuhmacher R., Lemmens M., Adam G., Krska R. (2005). Keywords: The deaths were mainly associated with homegrown maize that had not been treated with fungicides or properly dried before storage. (2021). Aflatoxin is produced by several soil-borne fungi or molds. Disclaimer. Occurrence of deoxynivalenol and its major conjugate, deoxynivalenol-3-glucoside, in beer and some brewing intermediates. Gilbert MK, Mack BM, Lebar MD, Chang PK, Gross SR, Sweany RR, Cary JW, Rajasekaran K. J Fungi (Basel). The main dominant microorganisms and potentially contaminating mycotoxins in dark tea. The main fungi that produce aflatoxins are Aspergillus flavus and Aspergillus parasiticus, which are abundant in warm and humid regions of the world. At the same time, the tea matrix composition is highly complex and specific, containing abundant tea pigments, polyphenols, caffeine, and other substances, which are the material basis for the health functions of tea, and such secondary metabolites also have the ability to stop or inhibit mycotoxin production by mycorrhizal fungi in the presence of fungal contamination (Zhao et al., 2017; Jiang et al., 2018). The common fungal toxins are aflatoxins (AFTs), ochratoxins (OTs), deoxynivalenol (DON), fumonisins (FUMs), zearalenone (ZEN), patulin (PAT), and Citrinins (CITs) (Haque et al., 2020; Vargas Medina et al., 2021). Fungi of many genera produce fungal toxins, mainly Aspergillus, Penicillium, Alternaria, Fusarium, and Claviceps genus (Murugesan et al., 2015; Jiang et al., 2018; Wang G. et al., 2020). Aflatoxin B1 and B2 are produced by A. flavus, while Aflatoxin G1 and G2 are synthesized by A. parasiticus and largely contaminate a wide range of food commodities including cereals (maize, sorghum, pearl millet, rice, and wheat), oilseeds (peanut, soybean, sunflower, and cotton), spices (chilies, black pepper, turmeric, coriander, and ginger), Mucor spp. Cui et al. In addition to these masked mycotoxins detected in naturally contaminated food, there are also masked mycotoxins that have been identified but not yet observed in naturally contaminated food. However, chili peppers may contain unsafe aflatoxin concentrations produced by Aspergillus section Flavi fungi. The essence of fermentation is the enzymatic reaction of extracellular enzymes produced by the secretion of dominant microorganisms and the action of moist heat (heat of microbial respiration and metabolism) combined. from Liupao tea fermentation samples. Results of ELISA were mostly positive for mycotoxins (Santos et al., 2009; Li W. et al., 2015), while LCMS/MS results were mostly negative, with only a few positive cases present. Biosensors (Basel). Dark tea can be mainly classified into Hunan Fuzhuan tea, Sichuan Kangzhuan tea, Hubei Qingzhuan tea, Guangxi Liupao tea, Yunnan ripe Pu-erh tea, and Shaanxi Fuzhuan tea, etc., and their main manufacture processes are shown in Figure 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. [34], Contamination of medicinal plants with mycotoxins can contribute to adverse human health problems and therefore represents a special hazard. Some strains of Trichoderma such as T. reesei and T. viride are capable of producing gliotoxin, which belongs to the Tricothecenes (Mao and Zhang, 2018). 2023 Jan 28;14(2):333. doi: 10.3390/mi14020333. Aflatoxins are a family of toxins produced by certain fungi that are found on agricultural crops such as maize (corn), peanuts, cottonseed, and tree nuts. Spices are susceptible substrate for growth of mycotoxigenic fungi and mycotoxin production. Zhao et al. The microorganisms in the fermentation process are the more abundant stage in the whole dark tea production process (Zhang et al., 2017; Xu Z. et al., 2019). Common Aspergillus spp. 2023 Feb 27;12(5):1006. doi: 10.3390/foods12051006. So far, there are more studies on the exposure of mycotoxins in tea, but there are fewer studies on the exposure, toxicity, and contamination status of masked mycotoxins. and Penicillium spp. Research progress in formation mechanism of fuzhuan brick tea quality, Study on the Influence of Advantage Fungi to Its Quality Components in the Process of Piled-Fermentation of Sichuan Brick Tea, Research progress and discussion on fungal contamination of dark tea. Iqbal S. Z., Nisar S., Asi M. R., Jinap S. (2014). Stachybotrys spores in animal studies have been shown to cause lung hemorrhaging, but only at very high concentrations. Some mycotoxins are harmful to other micro-organisms such as other fungi or even bacteria; penicillin is one example. P. expansum is especially associated with a range of moldy fruits and vegetables, in particular rotting apples and figs. Contamination of feedstuffs as well as food commodities by fungi occurs frequently in a natural manner and is accompanied by the presence of mycotoxins. The resulting data of several studies have thus far demonstrated that common exposures to airborne mycotoxins in the built indoor environment are below the CoNTC, however agricultural environments have potential to produce levels greater than the CoNTC.[27]. Formed during growth of these fungi on commodities such as cereals (e.g. 2018 Mar 20;9:317. doi: 10.3389/fpls.2018.00317. Zhao (2012) and Hu et al. Zhao (2012) isolated one strain of Fusarium spp., one strain of Trichoderma and three strains of Mucor spp. Exposure to mycotoxins causes disease in humans and animals. Each group is categorized by the ability to grow at a certain water activity requirement. An official website of the United States government. [Aflatoxins: current concepts on mechanisms of toxicity and their involvement in the etiology of hepatocellular carcinoma]. It is also the direction of future efforts by dark tea producers. A number of field control measures are being utilized or explored, including: modification of cultural practices; development of resistant crops through molecular and proteomic techniques; competitive exclusion using strains that do not produce aflatoxin; and development of field treatments that would block aflatoxin production. Sriwattanapong K, Slocum SL, Chawanthayatham S, Fedeles BI, Egner PA, Groopman JD, Satayavivad J, Croy RG, Essigmann JM. Citrinin is associated with yellowed rice disease in Japan and acts as a nephrotoxin in all animal species tested. government site. Wang G., Wang Y., Zhang H., Zhang C., Yang B., Huang S., et al.. (2020). official website and that any information you provide is encrypted Aflatoxins belong to a class of compounds known as mycotoxins. Penicillium fungi that may produce fungal toxins in dark tea. Li W., Xu K., Xiao R., Yin G., Liu W. (2015). Aflatoxins are mycotoxins produced by some fungi found on agricultural crops like peanuts, cottonseed, tree nuts, and maize (corn). So, the correct option is 'Fungi'. [30] Mycotoxins can also be removed chemically and biologically using antifungal/antimycotoxins agents and antifungal plant metabolites. 1College of Horticulture, Tea Refining and Innovation Key Laboratory of Sichuan Province, Sichuan Agricultural University, Chengdu, China, 2Faculty of Science and Agricultural Technology, Rajamangala University of Technology Lanna Lampang, Lampang, Thailand. The fungi of the genus Fusarium mainly include Fusarium graminearum, Fusarium verticillioides, Fusarium nivale, Fusarium tricinctum, and Fusarium equiseti etc. [34][35] Several mycotoxins reduce milk yield when ingested by dairy cattle. (2017). In humans it is predominantly an opportunistic pathogen of immunosuppressed patients. Also, the detection of mycotoxins exposure levels in dark tea is mainly for their prototypes and little attention has been paid to the risk of 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. [8] Because mycotoxins weaken the receiving host, they may improve the environment for further fungal proliferation. In the feed and food industry it has become common practice to add mycotoxin binding agents such as montmorillonite or bentonite clay in order to effectively adsorb the mycotoxins. (2015) suggested that in the solid-state fermentation process, there is a possibility of the presence of antagonistic microorganisms that inhibit the growth of harmful fungi and the production of mycotoxins. sharing sensitive information, make sure youre on a federal Aspergillus spp. Aflatoxin levels were determined in chili peppers from three states in Nigeria. Yu J., Bhatnagar D., Cleveland T. E. (2004). Public opinion often emerges that tea contains fungal contaminants that can cause cancer, and some scholars have also reported studies on dark tea being contaminated by fungal toxins (Liu et al., 2016, 2017; Cui et al., 2020; Li et al., 2020; Zhao et al., 2022), which has had a huge impact on the development of the industry.
