AflaGoggles for Aflatoxin Detection

2013-2015

The goal of the project is to develop portable, fluorescence spectral-based technology for rapid and non-invasive aflatoxin detection in maize. A detection device, AflaGoggle, will be developed in the project.

Effect of lemon grass (Cymbopogon citratus (DC.) Stapf.) treatments on Aspergillus flavus infestation and aflatoxin B1 content of maize grains

2011

Studies were conducted to determine the effect of lemon grass (Cymbopogon citratus (DC.) Stapf.) treatments on A. flavus (SGS-421) infestation of maize grains and aflatoxin B1 (AFB1) content of the grains.

The distribution and mycotoxigenicity of fungal isolates of stored maize grains from five agro-ecological zones of Nigeria

2011

Seventy composite samples of stored maize grains collected from farmers’ storage structures in five agroecological  zones of Nigeria (AEZs): Sudan Savanna (SS), Northern Guinea Savanna (NGS), Southern  Guinea Savanna (SGS), Derived Savanna (DS) and Humid Forest (HF) were examined for fungal  contamination. The isolates were further assessed for their abilities to produce mycotoxins in culture  medium.

Ocratoxin A Contamination of Nigerian Coffee Beans

2009

This paper is the first documented evidence of OTA contamination of coffee beans. Coffee beans were collected randomly from five warehouses in five states of Nigeria  located in the Derived Savannah (Oyo, Taraba, Kogi) and Humid Forest (Lagos and Edo) noted for cultivation of coffee beans. Contamination was noticed only in coffee beans from Kogi state; the major producer of coffee beans, Lagos and Oyo states with levels of 150,120 and 130ug/kg respectively. The values were above the EU limit of 2mg/kg and are thefore unsafe for human consumption

Correlation between aflatoxin M1 content of breast milk, dietary exposure to aflatoxin B1 and socioeconomic status of lactating mothers in Ogun State, Nigeria

2010

Aflatoxin M1 (AF M1), a hydroxylated metabolite of AF B1, is an important toxin that can contaminate the  milk of lactating mothers. A correlation study was conducted to determine the relationship between AF  M1 content of breast milk, dietary exposure to AF B1 and socioeconomic status of lactating mothers in the  three Senatorial districts of Ogun State, Nigeria.

Assessment of aflatoxigenic Aspergillus and other fungi in millet and sesame from Plateau State, Nigeria

2011

Sixteen fonio millet and 17 sesame samples were analysed for incidence of moulds, especially aflatoxigenic Aspergillus species, in order to determine the safety of both crops to consumers, and to correlate aflatoxin levels in the crops with levels produced by toxigenic isolates on laboratory medium. Diverse moulds including Alternaria, Aspergillus, Cercospora,Fusarium, Mucor, Penicillium, Rhizopus and Trichoderma were isolated. Aspergillus was predominantly present in both crops (46–48%), and amongst the potentially aflatoxigenic Aspergillus species, A. flavus recorded the highest incidence (68% in fonio millet; 86% in sesame kernels). All A. parvisclerotigenus isolates produced B and G aflatoxins in culture while B aflatoxins were produced by only 39% and 20% of A. flavus strains isolated from the fonio millet and sesame kernels, respectively. Aflatoxin concentrations in fonio millet correlated inversely (r = −0.55; p = 0.02) with aflatoxin levels produced by toxigenic isolates on laboratory medium, but no correlation was observed in the case of the sesame samples. Both crops, especially sesame, may not be suitable substrates for aflatoxin biosynthesis. This is the first report on A. parvisclerotigenus in sesame.

Fungal and bacterial metabolites of stored maize from five agro-ecological zones of Nigeria

2011-2012

Seventy composite samples of maize grains stored  in five agro-ecological zones (AEZs) of Nigeria where maize is predominantly produced were evaluated for the presence of microbial metabolites with the LC-MS/MS technique. The possible relationships between the storage structures and  levels of mycotoxin contamination were also evaluated.

Phenotypic differentiation of species from Aspergillus section Flavi on neutral red desiccated coconut agar

2013

In order to facilitate easy and rapid identification of aflatoxin-producing Aspergillus species, the phenotypic traits of Aspergillus section Flavi isolates were examined on neutral red desiccated coconut agar (NRDCA).

Palm Kernel: A Potential Substrate for Rapid Detection of Aflatoxigenic Fungi

2012

A culture medium was developed by incorporating fresh palm kernel extract to 2% agar for the detection of aflatoxigenic fungi. Further tests with isolates from different sources showed that yellow pigmentation, flourescence and aflatoxins were complementary on the medium thus obviating the need for a UV light in the screening process
