A total of 63 chicken feed samples based on cotton seed hulls, sunflower seed hulls, maize bran and mixed feeds were analysed using HPLC-FLD. It was revealed that all samples were contaminated with both TAF and AFB</span></span><sub><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">1</span></span></sub><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">, varying significantly with respect to their types. Specifically, 52.9% of the cotton seed hulls and 64.7% of maize bran samples exceeded the set tolerable limit of 5 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"> for AFB</span></span><sub><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">1</span></span></sub><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">. All sunflower seed hull samples were contaminated, showing varying mean concentrations of TAF across the sites: Manzese (150.48 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">), Mbagala (56.20 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">), Bunju (49.08 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">) and Kigamboni (33.83 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">). Remarkably, all chicken feed samples from the poultry farms were contaminated with levels beyond the recommended international maximum tolerable limit of 20 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"> of TAF for feeds with levels decreasing from Farm C (77.71 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">), Farm A (48.19 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">), Farm E (38.95 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">) and Farm F (24.48 ng g</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">−1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">). These findings call for urgent stringent quality control measures to mitigate aflatoxin contamination in chicken feeds, thereby safeguarding animal health and preventing potential health risks to humans.</span></span></p>}, number={3}, journal={Tanzania Journal of Science}, author={Muja, Mambaga S. and Mtei, Regina P. and Kilulya, Kessy F.}, year={2024}, month={Oct.}, pages={600–612} }
