Summary

This systematic review synthesises published evidence on the occurrence of aflatoxin B1 in livestock feed in Ethiopia, a country where warm, humid conditions and poor post-harvest storage practices create favourable conditions for Aspergillus mould growth. The review likely assesses the range of contamination levels reported across different feed types and geographic regions, whilst critically evaluating the sensitivity, specificity, and practical applicability of available detection methodologies. The paper contributes to understanding the food safety and animal health risks posed by mycotoxin contamination in sub-Saharan African livestock systems.

UK applicability

Direct applicability to UK conditions is limited, as Ethiopia's climate, feed storage infrastructure, and regulatory frameworks differ substantially from those in the UK; however, the review is relevant to UK importers of feed ingredients from East Africa and to policymakers concerned with global mycotoxin risk management and food chain safety.

Key measures

Aflatoxin B1 prevalence (%); contamination levels (µg/kg or ppb); detection methods (e.g. ELISA, HPLC, TLC, lateral flow assays)

Outcomes reported

The review examined the prevalence and levels of aflatoxin B1 contamination reported in livestock feed across Ethiopia, alongside an evaluation of the detection and analytical methods used to identify and quantify contamination.
