Aflatoxins are highly toxic fungal by-products produced by certain strains of Aspergillus fungi in more than 40 susceptible crops including maize and groundnuts. Aflatoxins can be separated into aflatoxins B1, B2, G1 and G2.
When ingested, aflatoxin B1 is metabolized to aflatoxin M1 which is secreted into milk. Aflatoxin B1 is particularly important because it has been found in most foods and animal feeds and is highly carcinogenic.
Aflatoxins cause around 90,000 cases of liver cancer each year and are strongly associated with stunting and immune suppression in children. Aflatoxins in contaminated animal feed can lead to reduced animal productivity. They can end up in products like milk, meat and eggs, thus presenting a health risk to humans, with children being particularly susceptible.
In Ethiopia, previous studies have investigated aflatoxin contamination in staple cereals, red chili pepper and ground peas. Now, a new research study published in the journal Food…
