Aflatoxin contamination of crops is frequent in warm regions across the globe, including large areas in sub-Saharan Africa. Crop contamination with these dangerous toxins transcends health, food security, and trade sectors. It cuts across the value chain, affecting farmers, traders, markets, and ...

A survey was conducted in Nairobi, Nyanza and Western provinces in Kenya between March and July2009 with 1263 peanut products sampled out of which 705 samples underwent microbial analysis. Thestudy aimed at determining the incidence of fungal species e emphasis on Aspergillus section Flavi eassoc...

Fungal species isolated from peanuts in major Kenyan markets: emphasis on Aspergillus section Flavi
Aspergillus flavus has long been considered to be an asexual species. Although a sexual stage was recently reported for this species from in vitro studies, the amount of recombination ongoing in natural populations and the genetic distance across which meiosis occurs is largely unknown. In the cu...

Peanuts are prone to various types of deterioration during storage which renders them unsuitable for consumption and trade resulting in large economic losses. Peanut kernels of Homabay Local, Valencia Red, ICGV-SM 12991 and ICGV-SM 99568 varieties were stored for six months in jute, polypropylene...

Effect of storage conditions on quality and aflatoxin contamination of peanuts (Arachis hypogaea L.)
Peanut kernels of Homabay Local, Valencia Red, ICGV-SM 12991 and ICGV-SM 99568 cultivars were storedfor six months in jute, polypropylene and polyethylene bags to assess the effect of storage bags, temperature andR.H. on fungal population and aflatoxin contamination.
