Aflatoxin Contamination and Rancidity in Locally Processed Commercial Fish Feeds and Ingredients along the Value Chain in Wakiso and Kampala Districts, Uganda
Aflatoxin
contamination and rancidity in locally processed commercial fish feeds and
ingredients along value chains is a Public and Animal health hazard. The study
established the level of aflatoxin contamination, peroxide value (PV), Anisidine value (AnV), and their
associated factors at storage areas among farmers, processors, traders,
factories, and landing sites in the Wakiso and Kampala districts. The value
chain actors were purposively selected in a cross-sectional study based on
access to the feed store and the use of locally processed commercial fish feeds
on farms. Data collected were statistically analyzed in SPSS version 20. All
the samples (45) were positive for aflatoxin contamination and PV with 51%
(23/45) of samples being contaminated with “above acceptable” aflatoxin levels
and 66.6% (30/45) of samples with “above acceptable” PV. The overall percentage of “above acceptable” AnV
was 11/29 (37.9%). Samples from factories were within acceptable contamination
levels. Multivariate logistic regression analysis revealed no significant
difference between aflatoxin contamination, peroxide, and Anisidine value with
storage factors for locally processed commercial fish feeds and ingredients.
The study recommended the purchase of fish feeds from factories and a larger
study on storage factors responsible for aflatoxin contamination and rancidity
in fish feeds in Uganda.
