Aflatoxin risk assessment in the dairy and poultry food chains in Ethiopia

  1. 1. Aflatoxin risk assessment in the dairy and poultry food chains in Ethiopia Barbara Szonyi, Dawit Gizachew, Azage Tegegne, Jean Hanson and Delia Grace International Livestock Research Institute (ILRI) Pictures Partners logo Dr Delia Grace (d.grace@cgiar.org ) Dr Barbara Szonyi (b.szonyi@cgiar.org) Dr Dawit Gizachew (dgizachew@gmail.com) This document is licensed for use under a Creative Commons Attribution –Non commercial-Share Alike 3.0 Unported License June 2012 October 2014 Our research questions along the food chains: Our research approach: risk assessment for human and animal health Risk assessment • Hazard identification • Hazard characterization • Exposure assessment • Risk characterization Risk communication • Interactive exchange of information and opinions Risk management • Assess policy alternatives • Select and implement appropriate options Improved detection methods: • Enzyme-Linked Immunosorbent Assay (ELISA) • All samples will be screened with ELISA • The ELISA determines quantitatively at the level of ng per liter (ppt) the aflatoxin concentration in samples • Further analysis and quantification of samples will be done using HPLC to compare the methods’ performance • High Performance Liquid Chromatography (HPLC) • HPLC is one of the most common methods to detect and quantify aflatoxins in food. It has been used jointly with techniques such as UV absorption, fluorescence and mass spectrometry • HPLC will be used to identify and quantify the different aflatoxins including B1, B2, G1 and G2 in feeds • Easiness of use and cost-effectiveness of techniques will be explored for future routine mycotoxin analysis Background and objectives: The prevalence and concentration of aflatoxins in food chains in Ethiopia are not well studied. Dairy and poultry products may contain aflatoxins that pose a threat to human health when consumed. In addition , contamination of animal feeds with aflatoxins has negative effects on poultry including reduction in weight gain and decreased egg production. Our objectives are to 1) study to the prevalence and concentration of aflatoxins in animal feeds, dairy and poultry in representative regions of Ethiopia, and 2) to identify approaches to mitigate the risk of exposure to aflatoxins in humans and animals using locally available methods.

Feed storage and processing • What are the risky practices? • What are the risk mitigating practices? • How can storage/processing practices be improved? Animal consumption • What are the feeding practices? • Which feeds are the most contaminated? Collection and processing of animal source foods (ASF’s) • How much aflatoxin is in different ASF’s? • Are there any processing methods that reduce the risk? Human consumption • What are the knowledge, attitude and practices (KAP) for consumption of ASF’s? • Are consumers aware of aflatoxins? • Who is at risk?
