Overview

Assesses aflatoxin B1 contamination and fungal diversity in livestock feeds, indicating urgent feed safety measures.

Key Points

  • The central aim is to evaluate the contamination levels of aflatoxin B1 and identify the diversity of fungal species in livestock feeds from markets in Addis Ababa.
  • Collected 290 samples of oilseed cakes and formulated feeds from feed vendors.
  • Analysed samples for aflatoxin B1 using ELISA and validated with HPLC.
  • Evaluated fungal diversity through DNA extraction and sequencing.
  • 92% of poultry rations and 72% of dairy rations exceeded the permissible aflatoxin level.
  • Ascomycota was the dominant fungal phylum across all feed types.
  • 53% of total fungal contamination was attributed to Aspergillaceae.
