In light of this, this review of relevant literature focuses on mycotoxin contamination, as well as various methods for the prevention and control of their prevalence, to avert its debilitating consequences on human health. Clear betdede E-posta Bilgileri of mycotoxin contamination is present in Africa, and it was therefore recommended that adequate prevention and control of these toxic substances in our food system should be encouraged and that appropriate measures must be taken to ensure food safety as well as the enhanced or long-lifespan of the African populace.
Governments, betdede E-posta Bilgileri institutions, and non-governmental organizations should tailor the limited resources available to tackle mycotoxin prevalence, as these will offer the best prospects for successful development of a sustainable food system in Africa. Over the years, mycotoxin contamination of food, feed, and agricultural products has emerged as an issue of serious concern, as these toxic substances in 1 may cause different types of poisoning and, consequently, diverse health problems from acute to chronic problems in both animals and humans 1.
Mycotoxins are natural contaminants of food and agricultural products all over the world 2. These secondary metabolites are betdede E-posta Bilgileri by toxigenic fungi 2which are classified as species of fungi that can produce one or more mycotoxins.
Mycotoxins can be produced by multiple fungal species 1 ; for example, aflatoxins and ochratoxins are produced by more than one fungal species 2and this contributes to the year-round presence of mycotoxins.
There are many different mycotoxins; apart from the aflatoxins and ochratoxins mentioned previously, other examples include fumonisins, zearalenone, trichothecenes, and patulin. Some of these have been classified by the world health organization WHO as human carcinogens. Most mycotoxins currently known are grouped based on their toxic activity under chronic conditions, into mutagenic, carcinogenic, or teratogenic mycotoxins.
For example, aflatoxins that occur naturally are classified as human carcinogens Group 1 ; ochratoxins and fumonisin are classified as possible human carcinogens Group 2Bwhereas trichothecenes and zearaleone are not recognized as human carcinogens Group 3 3. However, virtually all mycotoxins can cause one or more major health problems. In addition, some of these mycotoxins suppress the immune system 45thereby exposing the consumer to health threats. Moreover, the effect of mycotoxins on human health can be influenced by age, sex, weight, diet, exposure to infectious agents, quantity of toxins exposed, and the presence of other mycotoxins synergistic effects and pharmacologically active substances 4 — 6.
For example, in humans, the rate at which exposure to mycotoxins occurs betdede E-posta Bilgileri affect a young person or an infant to a greater degree than an adult 6 ; in addition, the quantity of exposure is a major determinant of the degree of toxicity to the consumer.
However, the severity of poisoning by these toxins can be complicated by factors betdede E-posta Bilgileri as vitamin deficiency, low calorie intake, alcohol abuse, or the presence of an infectious disease 5. In conclusion, over mycotoxins have been identified worldwide 6.
The increase in mycotoxin contamination in developing nations, predominantly Africa, is occurring at an alarming rate owing to poor implementation of thorough food scrutinizing policies that ensure contaminated foods are not sold to consumers. In light of this, this study focused on mycotoxins that have been previously detected and commonly found in Africa and the possible means of their prevention or reduction of contamination to the barest minimum.
This implies that mycotoxins are present all betdede E-posta Bilgileri, in stored food substances and ill-preserved food; when food substances are not well preserved, fungal growth may occur, leading to the production of mycotoxins. Moreover, mycotoxins can occur naturally 8which makes it easier for them to exist in the human environments and make them unsafe.
However, although many efforts have been made to completely eradicate mycotoxins from food and agricultural products, these methods have not been proven to be completely effective.
These methods may be physical, chemical, or biological detoxification strategies; furthermore, dietary strategies represent the most recent approaches to counteract the problem of mycotoxins 9. Humans can be exposed to mycotoxin through the consumption of contaminated plant-derived foods, from the carry-over of mycotoxins and their metabolites to animal products such as meat and eggs 10or from exposure to air and dust contaminated with toxins 11 Exposure to these toxins is more likely to predominate in parts of the world where there are poor methods for the pest infestation control of crops, transportation facilities, and storage facilities; however, it can also be rampant in societies with a high level of poverty, where people consume only the available and not the preferable.
Constant exposure to mycotoxins is also common where there are no rules and laws that protect the food intake of the populace. In developed countries, especially in subgroups in which poor food handling is common, there can be a risk of exposure to mycotoxins, making the populace vulnerable to mycotoxin-induced infections.
However because mycotoxins are natural contaminants 13their presence in food may be absolutely unavoidable. According to John and Miller 14mycotoxins betdede E-posta Bilgileri been the cause of epidemics in humans and animals for the last 30 years. Among these, the ergotism breakout in Europe led to hundreds of thousands of deaths in the last millennium. Mycotoxins were also the cause of alimentary toxic aleukia, which killed approximately a hundred thousand Russians between and They have the ability to inflict many illnesses, such as headaches and various gastrointestinal illnesses including abdominal pain, vomiting, and diarrhea 7 These toxins are known to be responsible for the death of millions of humans annually These are extremely toxic secondary metabolites of certain Aspergillus molds, such as Aspergillus flavusAspergillus parasiticusand Aspergillus nomius 1617which have been classified by the WHO as genotoxic and carcinogenic 7.
When ingested, inhaled, or absorbed through the skin, aflatoxins have carcinogenic, hepatotoxic, teratogenic, and mutagenic effects on human health, even at very small concentrations 615 They were shown to be the cause of Turkey X disease, i. hepatic necrosis, in Aflatoxins were also the cause of aflatoxicosis that occurred in,and Site Merkezi Casino alibahis Kenya Africa.
According to Makun et al. Inaflatoxins were the cause of the death of people in the eastern province of Kenya The exposure to AFB 1 in conjunction with a low protein diet, as described in 20caused a decrease in the weight gain and kidney dysfunction in rats.
Aflatoxins AFs are known to thrive in regions with high temperature and humidity, which are optimal for the growth of molds and the production of toxins 21 — When aflatoxins are ingested, inhaled, or absorbed through the skin, they cause carcinogenic, hepatotoxic, teratogenic, and mutagenic effects in human and animals rats, ferrets, ducks, trout, dogs, turkeys, cattle, and pigseven at low concentrations 615 According to Bilotti et al.
The chemical structure of some aflatoxins are shown in Fig. Chemical structure of aflatoxin. A Aflatoxin B 1B Aflatoxin B 2C Aflatoxin M 1D Aflatoxin M 2E Aflatoxin G 1F Aflatoxin G 2. Ochratoxins, produced by PenicilliumFusariumand Aspergillus species, are found naturally in various plant products such as cereals, coffee, beans, pulses, and dried fruits It has been found in rice and maize samples obtained from west Africa, specifically Nigeria Ochratoxin causes nephropathy in humans 27 ; it is also suspected to be the cause of Tunisian nephropathy and human Balkan endemic nephropathy BEN 28 This mycotoxin is known for its teratogenic effect; it can cause an adverse effect on the fetus in the womb owing its ability to cross the placenta and cause the malformation of the central nervous system and damage to the brain Darwish et al.
These are produced by various Fusarium species, including Fusarium verticillioides and Fusarium proliferatum verticillioideswhich is a major species of economic importance, grow as a corn endophyte in both vegetative and reproductive tissues, often without the appearance of disease symptoms in the plant.
It is present in virtually all corn samples. It has been found in maize and corn samples from Nigeria and South Africa 26 However, dependent on the weather conditions, insect damage, and the fungal and plant genotype, they can cause seedling blight, stalk rot, and ear rot Fumonisin has been linked to cancer of the esophagus in humans 34although it affects animals in different ways: it has been known to be the cause of various illnesses, such as leukoencephalomalacia in equines and rabbits 31 Zearalenone is a secondary metabolite from Fusarium graminearum.
Zearalenone is biosynthesized through a polyketide pathway by F. graminearumFusarium culmorumand Fusarium equiseti 5 These species are known as regular contaminants of cereal crops worldwide The consumption of zearalenone in small quantities has been proven to affect animal https://mister-baches.com/2-slot-game/kronosslot-bilgi-guevenliini-nasl-salyor-13.php, posing serious health threats and causing illnesses such as hyperestrogenic syndrome in pigs When zearalenone is present in large quantities, it can cause disrupt conception, abortion, and other problems These are produced by several fungal genera, which include FusariumTrichodermaMyrotheciumTrichotheciumVerticimonosporiumStachybotrysand Cephalosporium.
Benjabet Bahis Resmi Web Sitesinin Faydaları have been reported in Middle East Africa, where they were found to be present in feed and feed ingredients They are a large group of mycotoxins that consist of more than structurally related sesquiterpenoid mycotoxins produced from essential raw materials used in animal food and feeds such as maize, wheat, and oats 13 They are known to be strong inhibitors of protein synthesis that can be absorbed into the body through the skin to inhibit protein synthesis in the body, harming the health of its host Trichothecenes, such as other mycotoxins, are https://mister-baches.com/3-slot-machine/favexbet-ovu-arzbahis-53.php to heat.
Patulin is common in rotten apples, although it has been found in vegetables and other types of fruit, and has been detected in betdede E-posta Bilgileri and apple products in South Africa 40 It is produced specifically by Penicillium and Aspergillus 42and is stable even at high temperatures; therefore, it cannot be eliminated by thermal denaturation.
However, fermentation may reduce its stability InLlewellyn et al. Patulin was previously been used as antibiotic against Spor Bahisleri Ve Oranları and gram-negative bacteria, but was discovered to be toxic and therefore its use as an antibiotic has been discouraged Patulin is used as a potassium-uptake inhibitor in the laboratory and it also induces erythrocyte death at physiological concentrations The health effects of some mycotoxins are summarized in Table 1.
The prevention and control of mycotoxins Yeni Slot Oyunları Kazandırır be achieved by using mechanical, physical, chemical, and biological control strategies:. This involves the prevention of mold and fungus growth in crops and foodstuffs, as well as the continuous surveillance of mycotoxin in agricultural crops and general products. According to Clara 53the prevention of mycotoxin production in fungi from the field betdede E-posta Bilgileri usually considered the best approach to impede betdede E-posta Bilgileri harmful effects of mycotoxins on animals and human health.
Inoculum sources that can produce mycotoxins when decaying, such as weeds or agricultural residues, should be minimized to avoid contamination. According to Chang et al. Although the prevention of mycotoxin contamination in the field is strongly encouraged and offers the ideal approach to control mycotoxins 54it may not be possible to achieve this completely.
Therefore, postharvest strategies aimed at reducing the fungal contamination and, consequently, the mycotoxin content of agricultural products during storage, handling, processing, and transport must be put in place; this includes the improvement of drying and storage conditions, the use of chemical and natural agents, and irradiation This involves thorough cleaning to remove general dirt and may also involve washing with sodium carbonate solution or water.
Research has shown that the exposure of food items to very high temperatures, of at least °C, which is above cooking temperature, can reduce the mycotoxin content of food. However, food exposed to temperatures as high as those mentioned above might not be beneficial to the body owing to the loss of essential components and https://mister-baches.com/4-casino/betsat-hizmetler-in-deme-nasl-yaplr-57.php. Other means include the reduction of the moisture content of plants and seeds after harvest and during storage, the use of fungicides and preservatives against fungal growth, the prevention of insect infestation in stored products, as well as the removal of contaminated seeds.
Furthermore, Whitlow and Hager 37 suggested that insect-resistant seeds, which can resist insect damage and also fungal disease, must be planted as this will prevent the contamination of crops by mycotoxins while they are still in the field.
Whitlow and Hager 37 also reported that there should not be a delay in harvesting the crops, as this increases the chances of mycotoxin contamination. In addition, during harvest, he suggested that contact of the soil with agricultural products should be prevented, as this will also help to prevent the spread and contamination of these foods by mycotoxins.
In addition, the storage location should be kept at temperatures at which mold does not grow. Storage facilities should be sufficient to eliminate moisture migration, condensation, or leaks; grains stored for more than 14 days should be kept aerated and cool. This is important as aeration reduces the growth and spread of moulds that can cause contamination. In addition, Whitlow and Hager 37 also stated that storage facilities should always be checked for overheating and molding, as this should be prevented.
The use of accepted and standard methods for making silage cannot be overemphasized; they should be followed strictly to ensure the output of non-contaminated foods. Ammoniation is a widely-known method 58 that has received attention for the detoxification of aflatoxin- or ochratoxin-contaminated feeds and has been used Siteye Girilir betpuan Nasıl in several countries.
It completely decomposes OTA in corn, wheat, and barley Although the process does not lead to the formation and accumulation of toxic breakdown products of mycotoxins in agricultural products, it causes the observed changes in sensory and nutritional qualities, such as a brown color of the betdede E-posta Bilgileri cereals and decreases in lysine and sulfur-containing amino acids. Ammoniation is an approved procedure for the detoxification of aflatoxin-contaminated agricultural commodities and feed in some parts of the United States In addition, in France and Senegal, ammoniation is used for mycotoxin detoxification in contaminated peanut, cotton, and maize meals Alkaline hydrogen peroxide, sodium hydroxide, and monomethylamine or ammonium with calcium hydroxide treatments have also been found to be effective methods for OTA decontamination in this matrix Recently, the control of fungi producing mycotoxin has been achieved by using plant extracts and essential oil plant products as fungicides In stored grains, chemicals such as sodium bisulfite, ozone, and ammonia can be used to prevent the growth of fungi and the biosynthesis of mycotoxins 58 — Microbes and their enzymes can be applied for mycotoxin detoxification.
Several reports have described the OTA-degrading activities of the microbial flora of the mammalian gastrointestinal tract, including the rumen microbes of cows and sheep In addition, numerous other bacteria, protozoa, and fungi were shown to be able to degrade OTA It has been ascertained that lactic acid bacteria, propionic acid bacteria, and Bacillus sp.
can inhibit the growth of fungi and mycotoxin production Some enzymes, such as carboxypeptidase A 66 lipases from Aspergillus nigerand some commercial proteases 66 have also been identified as capable of performing this reaction.
Mycotoxins are a threat to human health as they may cause severe and irrevocable damage to human health, such as cancer, in the developing nations of the world.
It is known that almost nothing can be done to remove mycotoxins from food and feed once contaminated, because most mycotoxins are resistant to heat within the normal range of cooking temperatures. Therefore, the adequate prevention and control of these toxic substances in agricultural products while they are still on the field must be encouraged as this will drastically reduce the spread of mycotoxins and hence the reduction of various mycotoxin-induced illnesses.
