Occurrence of aflatoxin in some of the food and feed in Nepal
Koirala P, Kumar S, Yadav BK, Premarajan KC
Abstract
BACKGROUND: There are many contaminants like aflatoxin present in food products. Aflatoxin in comparison to many other contaminants is very toxic and also carcinogenic. There are reports of outbreak of aflatoxin toxicity in many parts of the world.
AIM: To find out the level of aflatoxin in common food and feed.
SETTING: The study was conducted in 16 districts of the Eastern region of Nepal.
METHODS AND MATERIALS: Samples were collected from retailers and whole sellers from 1995 to 2003. Common food items that had high chances of infestation were collected. Food sample were taken to the laboratory to estimate the level of aflatoxin. The thin layer chromatography method was used to detect aflatoxin in the samples and comparison of fluorescence of sample spot with fluorescence of standard for estimation.
RESULT: There were 832 samples for aflatoxin detection and estimation. One-third samples were found to be contaminated with aflatoxin. The highest percentage of contamination was found in peanut butter/vegetable oil (42.5%) and the lowest in areca nut (25%). Highest proportion of cornflakes samples were found to be contaminated with aflatoxin by more than the recommended value (30 ppb) and contamination in peanut was the lowest.
CONCLUSION: People consume many common food items that contain aflatoxin. It is of high importance for the concerned department to give attention to this important public health issue. Even in small doses, continuous consumption can lead to many health problems. So it is of paramount importance to detect and control these contaminants in food items.
