The present research work was carried out for the detection of aflatoxigenic fungus from poultry feed samples. During a period of 12 months (from June 2018 to June 2019), a total of 100 poultry feed samples comprising of 50 commercially prepared and 50 self compounded poultry feed were collected from different 5 different farms of Dinajpur districts, Bangladesh. Among the 100 feed samples Aspergillus spp was found on 54 feed samples with 54% prevalence. But Aflatoxigenic Aspergillus spp was found on 48 samples with 48% prevalence. In this study the prevalence of Aspergillus spp was 56% in self compounded poultry feed and 52% prevalence in commercially prepared poultry feed. There was no significant difference in the prevalence of Aspergillus spp and also in the prevalence of aflatoxigenic fungus isolated from commercially prepared feed as well as in self compounded feed on the basis of farms. Maximum level of aflatoxin was ≥20 ppb. This study alarms us about the potential risks of Aspergillus spp to public health if contaminate agricultural commodities such as grains or raw materials such as poultry feed. |
