Aflatoxin contamination has implications for the export of peanuts and the health of the vast majority of people who consume peanuts in their daily diets. Peanuts producers displayed low awareness of aflatoxin contamination and low knowledge of management practices' while extension staff and Author: GD Satish Kumar, MN Popat. Aflatoxin exposure from contaminated foods such as groundnuts affects an estimated billion people living in developing countries and causes childhood stunting and around a quarter of all liver.

Knowledge regarding aflatoxin contamination in groundnut and the risk of its ingestion was obtained showing knowledge score range of 0 to In all, % had good scores Aflatoxin Contaminationof Groundnut book 11 to None of the respondents had ever told their patients about the risk of aflatoxin by: aflatoxin contami nation in groundnut is probably due to resistance to pod infection, resista nce to seed invasion and colonisation b y the fungus, and resist ance to aflatoxinAuthor: Ephrem Guchi.
Aflatoxin contamination of groundnut is a serious problem in most groundnut producing countries and as such is given high research priority by the Groundnut Improvement Program of ICRISAT.
Since we have concentrated on selecting cultivars resistant to seed invasion and colonization by toxigenicAspergillus flavus, and/or to aflatoxin production following invasion by the Cited by: the maximum aflatoxin residue limit allowed in food for human consumption (FAO ). Due to aflatoxin contamination the food products cannot be exported leading to financial losses.
For example Malawi lost as much as 42% of its groundnut exports in (Diaz-Rios and Jaffe ). In the case of groundnut, three different types of resistance mechanisms, namely in vitro seed colonization (IVSC), pre-harvest aflatoxin contamination (PAC), and aflatoxin production (AP) have.

groundnut cake or haulms with small pods). This is called aflatoxin M 1. The effects of aflatoxin contamination • Alfatoxin is carcinogenic and can cause liver and other cancers in humans. • It is synergistic with hepatitis viruses B and C. • It lowers the body’s normal immune response to invasion by foreign substances.
• It impairs. The level of specific aflatoxin concentration varied between and ng g-1 for B2 and B1, respectively. Among contaminated samples of groundnut cake, 68% exhibited aflatoxin concentration below 20 ng g-1, while as high as ng g-1 aflatoxin B1 was recorded.
