Abstract
Mycotoxins detected included aflatoxin B1 and B2, ochratoxins A and B, patulin, sterigmatocystin, zeralenone and citrinin. Our results show the presence of mycotoxins in feed vis-a-vis deterioration in feed quality thus reducing shelf-life.
Highlights
Mycotoxin production as a result of mycotic contamination of animal feeds presents a major concern to public health due to the possible transmission of these toxic metabolites to meat, milk and animal products [1]
Investigations in this study indicated that the swine and poultry feed samples were infested with a varied mycotic genera which included Aspergillus spp., Penicillium spp., Fusarium spp., Rhizopus spp., Alternaria spp., Acermonium spp., Mucor spp. and Curvularia spp. concurring with reports by Zain et al [4]
Penicillium species was observed to proliferate in the poultry feed samples with an abundance of 33.1%, the abundance of this species would account for the detection of mycotoxins such as citrinin and patulin
Summary
Mycotoxin production as a result of mycotic contamination of animal feeds presents a major concern to public health due to the possible transmission of these toxic metabolites to meat, milk and animal products [1]. Mycotoxins include Aflatoxins (AFLs), OchratoxinA (OTA), Sterigmatocystin (EST), Fumonisins (FBS) and Zearalenone (ZEA) which are produce by Aspergillus spp., Penicillium spp. and Fusarium spp. in the tropics [2]. The production of these toxigenic secondary metabolites frequently occurs during the processing and storage of feed when environmental conditions such as moisture content and temperature becomes favourable for the proliferation of spoilage fungi thereby contaminating the entire food-chain from agricultural cultures to the plates of consumers [3,4]. To generate data on the mycological contamination and potential mycotoxins production with the aim of determining suitable shelf life for swine and poultry feed in the study area
