Abstract

The world losses of food grains due to storage fungi are about 5% of the harvested crops before consumption (FAO).
During storage these fungi might produce chemical substances (mycotoxins) that cause toxic symptoms when man or animal ingest contaminated food.
Aflatoxin is one of the most frequent contaminated mycotoxins in food stuffs. Aflatoxin are toxic mold metabolites produced by some toxigenic strains of Aspergillus flavus and A. Parasiticus that occur in many foods and feeds. Aflatoxins are among the most toxic substances known being acutely toxic to the liver and with chronic exposure, potent carcinogens of the liver. Symptoms of acute aflatoxicosis are fever, vomiting, coma and convulsions.
The aim of the study was to estimate the dietary intake of aflatoxin through the food consumption in Egypt.
1- To assess the food consumption pattern of adult to the suspected and frequently consumed foods.
2- To determine the level of aflatoxins in the suspected and frequently consumed food items.
3- To estimate the aflatoxins daily dietary intake.
To achieve this aim the following was carried out:
1- The suspected food item in the prepared food list was obtained from the main markets analyze for their aflatoxin content using high performance liquid chromatograph (HPLC) technique according to the method of AOAC to determine the aflatoxin level in the selected samples.
2- Estimation of aflatoxin intake of each person in the study in mg/ person/ day.
1- The sociodemographic characteristics of studied sample was taken according sex, age, marital status, education and occupation.
2- Distribution of sample was according to food habits as number of meals, which is the main meal, who care to have their breakfast and eating outside the house.
3- Determination level of aflatoxin in suspected food items:
I- Cereal and legumes (wheat, rice, corn and bean) it was found that corn had 4 types of aflatoxin with high concentration levels.
II- Nuts (peanuts, hazelnuts and almond) it was found that peanuts had the high level of aflatoxin.
III- Spices (nutmeg, cumin, coriander, cinnamon) it was found that cinnamon had the 4 types of aflatoxin B1, B2, G1 and G2 with high level.
IV- Miscellaneous (chocolate, cacao, macaroni, sesame, coconut, pickles, bread, bread maize). It was found that bread maize had very high concentration levels of aflatoxin.
4- Food frequency in daily intake:
I- Cereal and legumes:
Rice and beans were consumed once daily by high percentage.
II- Nuts:
Peanuts was consumed once weakly with high percentage more than the others.
III- Spices
Coriander and cumin was consumed once daily with high percentage the others.
IV- Miscellaneous
Bread was consumed once daily with high percentage followed by cocoa.
5- Relation between sex and average daily intake of aflatoxin from different food items. Only in cereal and legumes it was significant in the daily intake of aflatoxin G1 and G2 from rice the sex male was significant with females sex but in spices nuts and miscellaneous there was not significant.
6- Relation between age and average daily intake of aflatoxin from different food items was negative relation in cereal and legumes, species nuts and miscellaneous because aflatoxin can affect any age intervals.
7- Relation between marital status and average daily intake of aflatoxin from different food items in cereal and legumes aflatoxin G1, B1 from beans the consumption of single was significant with consumption of divorce/ widow.
8- Relation between education and average daily intake of aflatoxin from different food items was in cereal and legumes in the consumption of aflatoxin G1 and B1 in wheat in collage was significant with illiterate and read and write and also in miscellaneous the consumption of aflatoxin G1 and B1 from pickles in illiterate was significant with read and write secondary and collage.
9- Relation between occupation and average daily intake of aflatoxin from different food items according cereal and legumes, spices and nut there was no relation but in miscellaneous it was found that consumption of aflatoxin of G1, G2, B1 and B2 from cocoa in the retired was significant with not working employee.
