Abstract:
Aflatoxin levels in animal feed should be observed from the farm to the table to ensure the safety of
the feed to animals and humans. The contamination of cereals and other agricultural supplies used
in animal feed production could happen in the farm in the pre-harvest phase or in the post-harvest
phase. The study sought to determine Aflatoxin levels in broiler feed from selected farms in Nairobi
City County. A total of 42 feed samples were collected. Samples were analyzed using the
LCMS/MS technique. Results from the study show that Aflatoxin levels in broiler starter were;B1(17.26±3.07 ppb), B2 (2.44±0.84 ppb), G1 (8.87±2.41 ppb), G2 (0.9±0.44 ppb) and Total AF
(29.47±6.13 ppb). Aflatoxin levels in broiler finisher were B1 (17.17±3.09 ppb), B2 (2.68±1.18 ppb),
G1 (9.25±2.7 ppb), G2 (1±0.45 ppb) and Total AF (30.1±6.88 ppb). Results from analysis of feed
samples showed that AFB1 levels in both broiler starter and broiler finisher were above the KEBS
limit but were below the EAC, EU and WHO/FAO limit. Total Aflatoxin levels were above the KEBS
limit but below the EAC limit. There is need to enhance the capacity of feed surveillance and
monitoring in the country through various laboratory analysis techniques among various agencies
in the feed value chain to ensure feed safety.
