Mycotoxin-producing fungi contaminate food and feeds before, during and after harvest. Aflatoxins are important mycotoxins and aflatoxin B1 (AFB1) is a class 1 human carcinogen (definitely carcinogenic). Aflatoxin M1 (AFM1) is a class 2B (possible) human carcinogen. Aflatoxin B1 in feeds can decr...

Populations in tropical and subtropical developing countries are exposed to largely uncontrolled levels of aflatoxins through food. These countries (especially in Africa and Asia) also present a high prevalence of stunting. Studies have reported an association between aflatoxin exposure and growt...

This research reports a mapping of aflatoxin risk in the milk value chain in Kenya using a geographic information systems (GIS) approach. The objective was to spatially locate regions at risk by taking into account biophysical and socio-economic factors such as humidity and rainfall, dairy cattle...

From 1999 till 2001, management strategies for the reduction of aflatoxin in maize were developed in participatory tests with farmers. After 6 months of storage, maize in bags contained more aflatoxin than maize in traditional farmers’ stores. Harvesting maize late increased the risk of aflatoxin...

Milk is an important commodity in Kenya; the country has the largest dairy herd and highest per capita milk consumption in East Africa. As such, hazards in milk are of concern. Aflatoxin M1 (AFM1) is a toxic metabolite of aflatoxin B1 (AFB1) excreted in milk by lactating animals after ingesting A...

The aflatoxin (AF) albumin adduct is often used as a biomarker for aflatoxin exposure in humans. An ELISA method previously used for aflatoxin serum albumin in human blood was used to analyse bovine serum samples (n = 22) collected from dairy cattle during an aflatoxin mitigation study in Kenya. ...

Aflatoxin M1 (AFM1), a human carcinogen, is found in milk products and may have potentially severe health impacts on milk consumers. We assessed the risk of cancer and stunting as a result of AFM1 consumption in Nairobi, Kenya, using worst case assumptions of toxicity and data from previous studi...

BACKGROUND: Maize constitutes the main staple food and most important crop grown in Zambia. However, maize incursconsiderable losses both in field and storage due to pathogens and insects. Some of the pathogens and resultant mycotoxinsreduce the nutritional quality of the product. Mycotoxins are ...
