Vietnam is a tropical country with high temperature and precipitation, which may provide good conditions for fungal growth. A few limited studies have been conducted to evaluate the level of aflatoxin B1 in maize in Vietnam. In addition, no studies have been conducted to evaluate the perception a...

Aflatoxins are toxic byproducts from some Aspergillus fungi, mainly Aspergillus flavus, colonizing crops before and after harvest, with preference for maize and groundnuts. In large quantities the toxins are mainly hepatotoxic, and can cause death due to liver failure. Chronic low-dose exposure h...


Lindahl, Johanna F.Senerwa, D.M.Mwangi, G.Sirma, A.J.Atherstone, ChristineGrace, Delia[Are aflatoxins a One Health issue? Results and insights from studies on aflatoxins in the East African dairy value chains]Are aflatoxins a One Health issue? Results and insights from studies on aflatoxins in the East African dairy value chains

Aflatoxins are carcinogenic, toxic and immunosuppressive substances produced by some species of the fungal genus, Aspergillus. Consumption of aflatoxins can have serious health effects. Widespread in the tropical and sub-tropical world, aflatoxin B1 (AFB1) is found in many staple foods and feeds;...


Mutua, F.Lindahl, Johanna F.Grace, Delia[Availability and use of mycotoxin binders in selected urban and peri-urban areas of Kenya]Availability and use of mycotoxin binders in selected urban and peri-urban areas of Kenya

Background: Worldwide, milk forms a major part of human diet especially for children and expectant mothers. However, milk in East Africa has been shown to be frequently contaminated with aflatoxin M1 (AFM1) and bacteria. The efficacy of NovaSil clay (NS), a mycotoxin binder, and Mazzican, a hygie...


Anyango, G.Mutua, F.Kagera, I.Andang'o, P.Grace, DeliaLindahl, Johanna F.[Efficacy of mycotoxin binder on aflatoxin M1 and Mazzican on total bacterial count in raw milk among smallholder dairy farmers in Kisumu County, Kenya]Efficacy of mycotoxin binder on aflatoxin M1 and Mazzican on total bacterial count in raw milk among smallholder dairy farmers in Kisumu County, Kenya

Aflatoxin-contaminated food is a public health concern. Contamination of staple foods in Kenya has in the past led to loss of human lives as well as condemnation of large quantities of food, contributing to food insecurity. This study investigated the occurrence of aflatoxins in maize, millet and...


Sirma, A.J.Senerwa, D.M.Grace, DeliaMakita, K.Mtimet, NadhemKang'ethe, Erastus K.Lindahl, Johanna F.[Aflatoxin B1 occurrence in millet, sorghum and maize from four agro-ecological zones in Kenya]Aflatoxin B1 occurrence in millet, sorghum and maize from four agro-ecological zones in Kenya

In the tropics, staples such as maize are often contaminated with mycotoxins, harmful by-products of fungal metabolism. In particular, high exposure to aflatoxins may cause fatal illness in people and animals, while chronic exposure can cause liver cancer in humans and, in domestic animals, growt...


Kiama, T.N.Lindahl, Johanna F.Sirma, A.J.Senerwa, D.M.Waithanji, Elizabeth M.Ochungo, P.A.Poole, Elizabeth J.Kang'ethe, Erastus K.Grace, Delia[Kenya dairy farmer perception of moulds and mycotoxins and implications for exposure to aflatoxins: A gendered analysis]Kenya dairy farmer perception of moulds and mycotoxins and implications for exposure to aflatoxins: A gendered analysis

Malnutrition is a major problem in East Africa and animal source foods could provide essential protein and micronutrients to help alleviate this. The livestock sector is rapidly growing and intensifying in response to increased consumer demand for animal source foods. However, the ability of the ...


Atherstone, ChristineGrace, DeliaLindahl, Johanna F.Kang'ethe, Erastus K.Nelson, F.[Assessing the impact of aflatoxin consumption on animal health and productivity]Assessing the impact of aflatoxin consumption on animal health and productivity

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...
