Aflatoxins are among the most carcinogenic substances known. [27][28], The expression of aflatoxin-related diseases is influenced by factors such as species, age, nutrition, sex, and the possibility of concurrent exposure to other toxins. Aflatoxin B1 is a food contaminant and a hepatocarcinogen. This site needs JavaScript to work properly. AF36 is a fungal antagonist and is applied as a commercial biocontrol to cotton and corn to reduce aflatoxin exposure. 2020 Oct 29;18:3267-3277. doi: 10.1016/j.csbj.2020.10.020. In many of these contaminated food products, the aflatoxin exceeded the safe limits of the U.S. Food and Drug Administration (FDA), or other regulatory agency. [14] The FDA has had occasion to declare both human and pet food recalls as a precautionary measure to prevent exposure. In dogs, aflatoxin has potential to lead to liver disease. Microbiol, 1974, 27, 1118–1123. Aspergillus section Flavi historically includes species with conidial heads in shades of yellow-green to brown and dark sclerotia.Hedayati et al. Abstract. of Aspergillus flavus, Aspergillus parasiticus, and Aspergillus nomius. Symptomatic and supportive care tailored to the severity of the liver disease may include intravenous fluids with dextrose, active vitamin K, B vitamins, and a restricted, but high-quality protein diet with adequate carbohydrate content. The conidia disperse into the air and the environment via insect (bugs)and wind type of pollinations. Taxonomy: Growth of the fungus on a food source often leads to contamination with aflatoxin, a toxic and carcinogenic compound. This approach provides a more integrated measure of exposure over several weeks or months. [22], There is very limited evidence to show that agricultural and nutritional education can reduce exposure to aflatoxin in low to middle income countries. COVID-19 is an emerging, rapidly evolving situation. Aspergillus flavus is a diverse assemblage of strains that include aflatoxin-producing and non-toxigenic strains with cosmopolitan distribution. [8][9] Furthermore, a causal relationship between childhood stunting and aflatoxin exposure has yet to be conclusively shown by epidemiological studies, though such investigations are under way. All the isolates were found to be aflatoxigenic. Despite the importance of this toxin to humans, it has remained unclear what the fungus gains by producing aflatoxin. Aflatoxin production of species and strains of the Aspergillus flavus group isolated from field crops. The well-documented AFM1 associated adverse health outcomes include hepatocarcinogens, mutagens genotoxins, mutagenicity, and teratogen. Aspergillus flavus can produce aflatoxins on cheddar cheese, with the toxin penetrating up to 1.28 cm into the cheese. Hara S, Fennell DL, and Hesseltine CW. Aflatoxins are poisonous carcinogens and mutagens that are produced by certain molds (Aspergillus flavus and Aspergillus parasiticus) which grow in soil, decaying vegetation, hay, and grains. The term "aflatoxin" is derived from the name of one of the molds that produce it, Aspergillus flavus. It is mainly a saprophyte and grows on dead plant and animal tissue in the soil, which is important for the recycling of nutrients. In this study, we analysed the inhibitory effect of 30 tea aqueous extracts on the growth and aflatoxin production of Aspergillus flavus. Under improper storage conditions, A. flavus is capable of growing and forming aflatoxin in almost any crop seed. Low levels of aflatoxin exposure require continuous consumption for several weeks to months in order for signs of liver dysfunction to appear. Although Aspergillus flavus and Aspergillus parasiticus are the main microorganisms of concern in peanuts, due to aflatoxin contamination, several Salmonella outbreaks from this product have been reported over the last ten decades. The main fungi that produce aflatoxins are Aspergillus flavus and Aspergillus parasiticus, which are abundant in warm and humid regions of the world. Aflatoxin B1 is a carcinogenic compound produced by Aspergillus flavus, a common soil fungus, that induces transversion of G to T at codon 249 of the p53 tumor suppressor gene. It did not cause any increase in decay of pistachio, almond, and figs. In the field, aflatoxin is associated with drought-stressed oilseed crops including maize, peanut, cottonseed and tree nuts. Singh P, Mehl HL, Orbach MJ, Callicott KA, Cotty PJ. It is an extremely common soil fungus. Mycotoxin production by three different toxigenic fungi genera on formulated abalone feed and the effect of an aquatic environment on fumonisins. orchards. SO: Mycopathologia, 136(1):53-63. Aspergillus flavus strain AF36 is not carcinogenic and is toxin-free. Aflatoxins [4], High-level aflatoxin exposure produces an acute hepatic necrosis (acute aflatoxicosis), resulting later in cirrhosis or carcinoma of the liver. 2018 Mar 20;9:317. doi: 10.3389/fpls.2018.00317. The contamination of Aspergillus flavus and subsequent aflatoxins (AFs) has been considered as one of the most serious food safety problems due to their acute and chronic adverse effects on humans and animals. 6-10 Among the aflatoxin groups, aflatoxin B1 is the most potent carcinogen. An association between childhood stunting and aflatoxin exposure[5] has been reported in some studies[6][7] but could not be detected in all. Majumdar R, Lebar M, Mack B, Minocha R, Minocha S, Carter-Wientjes C, Sickler C, Rajasekaran K, Cary JW. Aspergillus flavus is an opportunistic pathogen of crops. [1] In the field, A. flavus is predominantly a problem in the oilseed crops maize, peanuts, cottonseed and tree nuts. [31] Some articles have suggested the toxic level in dog food is 100–300 ppb and requires continuous exposure or consumption for a few weeks to months to develop aflatoxicosis. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2019 Kenya: five brands of maize flour recalled due to contamination. The native habitat of Aspergillus is in soil, decaying vegetation, hay, and grains undergoing microbiological deterioration, but it invades all types of organic substrates whenever conditions are favorable for its growth.
