ABSTRACT
Introduction@#Humans are exposed to aflatoxins by consuming foods contaminated with products of fungal growth. Aflatoxin is associated with both acute and chronic toxicity in humans including acute liver damage, liver cirrhosis, and liver cancers. The risk of liver cancer in individuals exposed to chronic HBV infection and aflatoxin is up to 30 times greater than the risk in individuals exposed to aflatoxin (Groopman JD, Kensler TW, Wild CP, 2008). Thus, we aimed to assess the awareness regarding aflatoxins in individuals exposed to B virus infection. @*Goal@#To assess the knowledge regarding aflatoxin for individuals exposed to B virus infection.@*Materials and Methods@#In order to study the knowledge of subjects exposed to B virus infection regarding aflatoxins, information from 308 individuals who agreed to participate in this survey was collected through by 11 different questions, and data analysis taken in 308 subjects’ information. @*Result@#In the total subjects studied, 175 were female and 133 were male. One and three percent of the participants had no formal schooling, 8.8% completed college, 53.3% had a secondary education, 36.6% had university education level. </br> By the results, 88.4% out of 309 individuals had no head about aflatoxin. All 309 individuals had answered to the questions “What are the aflatoxins“. Eighty three and nine percent out of 309 individuals said did not know. Also they answered to the questions “How is aflatoxin produces“. Eighty and three percent out of 305 individuals said did not know. Also, 291 participants answered to the questions “Does it produce in foods“. Fifty one and sex percent said “No”. Furthermore, 296 participants had answered to the questions “Does it produce in grain foods“. Fifty three and seven percent said did not know. Also, all of 303 participants answered to the questions “How is aflatoxin harmful to human health“. Seventy one and sex percent said did not know.@*Conclusion@#Findings of this survey indicated that the awareness regarding aflatoxin was poor and inadequate in studied individuals. Therefore, this survey results shows that the importance on the raising the awareness of aflatoxin in individuals exposed to B virus infection.
ABSTRACT
Introduction@#According to the 5th National Nutrition Survey, 6.1 percent of all children were stunted and 1.4 percent had severe stunts. Stunts are a manifestation of chronic nutrition disorders caused by repeated and chronic diseases, not having adequate nutrition for a long time. </br> The National Nutrition Survey, published in the National I-V study, assesses the nutritional status of under-five children. However, studies on nutritional, nutrient, and safety in children are not yet available. Therefore, it is necessary to study the nutritional and nutritional qualities of children in kindergartens.@*Goal@#To evaluate the nutrition of children in the kindergarten, calories and nutrients, and evaluate whether they meet the established norms.@*Material and Method@#The survey covered 96 kindergartens. Survey data based on food expenditure report of kindergarten, were processed by Microsoft Excel. Calories and nutrients are calculated by calculation method.@*Results@#The use of milk and dairy products for children in kindergartens was 1.1-1.8 times, flour product consumption was 1.5 times, vegetable consumption was 1.7 times, fruit consumption was 4.1 times lower than the approved recommendations. </br> The consumption of meat and meat products for children was 1.2 times, rice consumption was 1.6 times, sugar and sweet products was 1.4 times higher than the approved recommendations. </br> The number of protein for children in kindergartens is 1.2, fat is 1.1, carbohydrate is 1.3 times less, and feeds averaging 1038.6 kcal per day, which is 310.6 kcal less than the approved recommendation. @*Conclusion@#Kindergarten children cannot get sufficient quantities of milk, dairy products, fruits The amount of meat, flour, rice, and sweet foods for children of the kindergarten is greater than the recommended size. </br> The calorie of diet for children in kindergarten is less than 310 calories from the recommended level
ABSTRACT
ObjectiveThis study aimed to assess the prevalence of the total aflatoxin in peanuts, and their concentration level.Material and MethodThis cross-sectional survey was conducted in seven district of Ulaanbaatar, the capital city of Mongolia,from March to December 2015.A total of 41 samples of peanuts were randomly collected from the survey area, from March to December2015. An ELISA test was used for detection the total aflatoxins(B1+B2). The relative humidity andtemperatures of the storage areas were measured at the time of sampling the peanut.ResultsThe Frequency statistics analysis showed that 61% of all analyzed peanut samples had detectablelevels of the total aflatoxinat 0.05 μg kg-1. The prevalence of samples contaminated with the totalaflatoxins(B1+B2) were higher among analysed samples of the tree nuts, peanuts imported from China,and canned nuts (P<=0.01). Levels of the total aflatoxins were less than the maximum permissible limitsof 15 μg kg by the regulation of European Union and worldwide. The mean values of the storage relativehumidityat the time of sampling peanuts were higher than the recommended storage relative humidity incorn cereals (<13%). Furthermore, the mean values of the storage temperatures at the time of samplingpeanuts were higher in groundnut peanuts, cedar’s nut and peanuts imported from China than therecommended level of the storage temperature in corn cereals (10°C-21°C).Conclusion:The prevalence of the total aflatoxin in peanuts was higher. The level of the total aflatoxins were less thanthe maximum permissible limits of 15 μg kg-1 by the regulation of European Union and worldwide. Thestorage relative humidity and temperatures of peanuts may encourage the growth of fungi-producingaflatoxins. Thus, a national strategy for the elimination of aflatoxin in foods is needed in Mongolia.
ABSTRACT
This cross-sectional survey was conducted in seven district of the capital city Ulaanbaatar ofMongolia, and border post in Zamiin-Uud, and Altanbulag province from March to December 2015.A total of 380 samples including 70 flours, 114 rice’, 41 various peanuts, 15 maize and maizeproducts, 24 milks, 6 yoghurts, 39 beers, 27 dried fruits and 44 herbal teas were randomly collectedfrom supermarkets, hypermarkets, department stores, factories, and bazaars in Ulaanbaatar city,and Zamiin-Uud, and Altanbulag province.HPLC (High performance liquid chromatography), and enzyme-linked immunosorbent assay (ELISA)were used for the total aflatoxins (B1+B2) and aflatoxin M1 detection.The survey found that (148) 38.9% of all analysed food samples were contained aflatoxins (B1+B2),and aflatoxin M1 were ranging from 0.0094 μg kg-1to 2.4μg kg-1. The levels of aflatoxins (B1+B2)were below the maximum tolerance limit in EU and worldwide regulations. Mean concentrationlevel of aflatoxins (B1+B2) was 0.17 μg kg-1 in all positive samples. Mean daily low and high foodintake were respectively, 63 g and 245 g. Based on the daily food consumption data, estimatedexposure dose of aflatoxins (B1+B2) was 0.16734 mg kg-1bw day-1 in individuals with a daily low foodintake, and 0.65078 mg kg-1bw day-1 in individuals with a daily high food intake (95th percentile). Theexposure dose of aflatoxins from daily high food intake exceeds the estimated provisional maximumtolerable daily intakes, 0.4 μg kg-1 body weight day-1 for adults with hepatitis B (Kuiper-Goodman,1998). Furthermore, estimated excess cancer risk values to liver cancer incidence by ingestion ofthese foods for aflatoxins (B1+B2) and aflatoxin M1were calculated to be 0.0448 mg kg-1bw day-1forindividuals negative for hepatitis Band 1.344 mg kg-1bw day-1 for individuals positive for hepatitis B.Thus, the findings of our survey showed that the potential hazard associated with aflatoxin in foodin Mongolia has not been serious. However, most researchers suggested that no level of aflatoxinexposure is considered safe.Conclusion: Currently, the levels of the total aflatoxins and aflatoxin M1 were lower than the maximumpermissible levels in UE and the USFDA, and worldwide regulations. Currently, estimated exposuredose of the total aflatoxins and M1aflatoxin through daily high food intake was risked in populationwith hepatitis B virus. However, in Mongolian population has not been excess liver cancer risk.
ABSTRACT
Afl atoxins are a type of mycotoxin produced by Aspergillus species of fungi, such as A. fl avus andA.parasiticus. Afl atoxins are the most potent hepatocarcinogen and mutagen among mycotoxins.Afl atoxins can effects a wide range of commodities, including crops, cereals, peanuts, maize, beans,and milk and fruits. Thus, we carried out a monitoring surveillance survey on the afl atoxins level in somefood commodities. In early stage of this survey we tested a total of 112 samples of foods including fl our,rice, peanuts, maize, dried fruits, milk, and cereals. According to the preliminary results of this survey,59 (52.7%) samples of foods including fl our, rice, peanuts, maize, dried fruits, milk, and cereals’ sampleswere positive for a total afl atoxins (AFB1+AFB2+AFG1+AFG2). Although levels of total afl atoxins in allsamples were at permissible limits by the commission regulation of EU, the strategies for the preventionand control of mycotoxin are required in Public health system and Agricultural organization in Mongolia.Since afl atoxins is the most well-known mycotoxin ever thoroughly studied and its prevention and controlhas been most successfully practiced in various countries, therefore, this paper will focus on the strategyfor the prevention and control of afl atoxins’s mycotoxin contamination food in Mongolia.
ABSTRACT
Aflatoxins are the secondary metabolites of the fungi namely, Aspergillus flavus and A. parasiticus. They can colonize and contaminate grain before harvest or during storage. There are about twenty related secondary forms of aflatoxins, and subtypes B₁, B₂, G₁, G₂. These aflatoxins frequently contaminate the foods and feeds (Yu J et al, 2000, Imanaka BT et al, 2007). Aflatoxin B1, the most toxic, is a potent hepatocarcinogenic and genotoxigenic metabolites that have been classified as group I carcinogens by International Agency of Research on Cancer (International Agency for Research on cancer, 1993). Aflatoxin M1 is found in milk of lactating cows that have consumed feeds contaminated with aflatoxin B₁. Aflatoxin M₁ was originally classified as a Group 2B human carcinogen in 1993, but subsequent evidences of its cytotoxic, genotoxic and carcinogenic effects led to a new categorization of aflaoxin M1 as Group I (International Agency for Research on cancer, 2002). Aflatoxins can affect a wide range of commodities, including crops, cereals, oilseeds, spices, tree nuts, milk, meat, and dried fruit (Wilson DM et al, 1994, Bao L et al, 2010). Mongolia has been imported foods about 60 percent of food demands including wheat, flour, rice, milk, dairy products, peanuts and maize. This situation is required to study aflatoxin contamination in food in Mongolia. Epidemiological studies have found that dietary exposure to aflatoxin and chronic infection with hepatitis B, C virus are three major risk factors for HCC (Viviani et al. 1997; Hall et al. 2003). HCC as a result of chronic aflatoxin exposure has been well documented, presenting most often in persons with chronic hepatitis B virus (HBV) infection (Wild and Gong, 2010). The risk of liver cancer in individuals exposed to chronic HBV infection and aflatoxin is up to 30 times greater than the risk in individuals exposed to aflatoxin (Groopman et al., 2008). According to the WHO, the national liver cancer incidence rates was 54.1 per 100.000 population, the prevalence of HBV and HCV infection in 11.8%, 15.6% were respectively (J.Abarsanaa, 2012). This situation is a serous public health problem in Mongolia. Thus, we aimed to carry out the monitoring surveillance survey on the aflatoxin contamination level in some food.
