Mid-Infrared Spectral Characterization of Aflatoxin Contamination in Peanuts
Contamination of peanuts by secondary metabolites of certain fungi, namely aflatoxins present a great health hazard when exposed either at low levels for prolonged times (carcinogenic) or at high levels at once (poisonous). It is important to develop an accurate and rapid measurement technique to …

Investigation of methods for reducing aflatoxin contamination in distillers grains
… overall goal of this project was to reduce the aflatoxin level in the final coproduct of ethanol bioprocessing--DDGS. This was pursued by examining the effects of reduction of aflatoxin in the incoming corn prior to bioprocessing, the degradation of aflatoxin in the intermediate products, namely …

Investigating aflatoxin contamination and knowledge levels in producing safe peanut butter among selected Lusaka urban processors.
Aflatoxin contamination is a major global public health problem especially in developing countries. Its risk effect on human consumption of peanut butter has posed a serious public health challenge by increasing morbidity and mortality in human populations. In Zambia, local and international peanut …

APPLYING HAZARD ANALYSIS CRITICAL CONTROL POINT (HACCP) PRINCIPLES TO MITIGATE AFLATOXIN CONTAMINATION IN MAIZE PRODUCTION IN GHANA
<p>Aflatoxin contamination in maize or corn has a significant health risk, production risk, and economic losses in Ghana's agricultural sector. This study uses the hazard analysis critical control point (HACCP) principle to estimate the cost and benefit of aflatoxin prevention in maize production. …

Modeling pre-harvest aflatoxin incidence in groundnut (arachis hypogaea l.) using selected soil properties and ambient temperature
Aflatoxin contamination of groundnut (Arachis hypogaea L.) and its products is a worldwide food safety concern. Contamination of kernels during crop growth is associated with adverse soil factors and weather conditions. Therefore, good agricultural practices are an important strategy to minimize …

Environmental Degradation of Aflatoxins and Genetic Diversity of Aspergillus Section Flavi with a Focus on Mozambique
Aflatoxins are potent hepatotoxic, carcinogenic, genotoxic secondary metabolites produced by species in Aspergillus section Flavi that contaminate foods and feeds worldwide. Aflatoxin contamination of staple crops is endemic in Mozambique, and the country has one of the highest rates of liver …

Using single corn kernel classification, pooling, and simulation to address skewness and clustering in aflatoxin distribution
Aflatoxin contamination in corn has posed a serious health risk to consumers. To detect aflatoxin contamination in a lot, one may adopt the bulk sampling approach to estimate the overall aflatoxin concentration in the lot, compare it against the aflatoxin action level, and decide whether to accept …

An Economic Surplus Evaluation of Aflatoxin-Reducing Research: A Case Study of Senegal's Confectionery Groundnut Sector
… to the fact that groundnuts are susceptible to aflatoxin contamination, stringent aflatoxin standards have been imposed on groundnut trade by many developed countries. For Senegal and other groundnut exporters in the developing world, these aflatoxin standards pose a major challenge. As a …

Effects of Storage Conditions of Aspergillus Growth and Aflatoxin Production in Peanuts. A Study in Ghana
… leguminous crop is frequently contaminated with aflatoxins, which are secondary metabolites of some Aspergillus fungi, mostly Aspergillus. flavus and Aspergillus parasiticus. Aflatoxins in foods are known to cause liver cancer, stunted growth in children, immune system disorders and economic …

Molecular and bio-analytical characterisation as a means to understand genetic diversity within Kenyan Aspergillus flavus strains
… flavus isolates were also further analysed for aflatoxin production potential using quantitative real-time PCR and various bioanalytical techniques. The influence of the maize lines grown in Kisumu, Homa Bay, Nandi and Makueni region on A. flavus infection and aflatoxin production was also …

Preliminary investigation of the natural contamination of agricultural crops with selected mycotoxins in northern rural South Africa (Limpopo and Mpumalanga Provinces)
… South Africa. However poor storage practices and contamination with mycotoxins, particularly fumonisins and aflatoxins impacts adversely on production, food safety and food security. Mycotoxins are toxic natural food-borne compounds which frequently contaminate agricultural produce worldwide. They …

Develop Methods To Evaluate the Performance of Aflatoxin Sampling Plans for Shelled Corn.
Eighteen lots of shelled corn were tested for aflatoxin contamination. The variability and distributional characteristics associated with the aflatoxin testing procedure were investigated. The total variance associated with testing shelled corn was estimated and partitioned into sampling, sample …

Impact of dietary modification on aflatoxicosis in poultry
<p>Aflatoxin contamination in feed and feed ingredients is of high worldwide prevalence, posing serious risks to the livestock industry. A series of studies were conducted to better understand the comprehensive impact of aflatoxicosis and its interrelationships with dietary modifications in broiler …
