Soybean lines lacking lipoxygenase (LOX) activity were compared with soybean lines having LOX activity for the ability to support growth and aflatoxin B1 production by the fungal seed pathogen Aspergillus flavus. Whole seeds, broken seeds, and heat-treated (autoclaved) whole seeds were compared. Broken seeds, irrespective of LOX presence, supported excellent fungal growth and the highest aflato...

Aflatoxins, carcinogenic toxins produced by Aspergillus fungi, contaminate maize, peanuts, and tree nuts in many regions of the world. Pistachios are the main source of human dietary aflatoxins from tree nuts worldwide. Over 120 countries have regulations for maximum allowable aflatoxin levels in food commodities. We developed social network models to analyze the association between nations' af...

In May 2004, CDC Kenya, trainees of the CDC-supported Field Epidemiology and Laboratory Training Program (FELTP) in Kenya, the World Health Organization, and CDC were invited by the Kenya Ministry of Health (KMOH) to participate in the investigation of an outbreak of jaundice with a high case-fatality rate (CFR) in the districts of Makueni and Kitui, Eastern Province. Preliminary laboratory tes...

A high-affinity IgM monoclonal antibody specific for aflatoxins was covalently bound to Sepharose 4B and used as a preparative column to isolate aflatoxin derivatives from the urine of people and experimental animals who had been exposed to the carcinogen environmentally or under laboratory conditions. Aflatoxin levels were quantified by radioimmunoassay and high-performance liquid chromatograp...

Aflatoxin contamination and rancidity in locally processed commercial fish feeds ingredients along value chains is a Public Animal health hazard. The study established the level of aflatoxin contamination, peroxide (PV), Anisidine (AnV), their associated factors at storage areas among farmers, processors, traders, factories, landing sites Wakiso Kampala districts. chain actors were purposively ...

Almonds are among the commodities at risk of aflatoxin contamination by Aspergillus flavus. Temperature and water activity are the two key determinants in pre and post-harvest environments influencing both the rate of fungal spoilage and aflatoxin production. Varying the combination of these parameters can completely inhibit or fully activate the biosynthesis of aflatoxin, so it is fundamental ...

aflatoxin m1 (afm1) is an important mycotoxin frequently found in milk and dairy products. dairy products and colostrum may be contaminated by aflatoxin m1 when dairy cattle have fed with aflatoxin b1-contaminated feeds. this study was undertaken in a dairy farm around tehran province to determine the presence and level of aflatoxin m1 (afm1) in spray dried and lyophilized colostrum samples. in...

Since 2003, non-compliant aflatoxin concentrations have been detected in maize produced in Italy. The most successful worldwide experiments in aflatoxin prevention resulted from distribution of atoxigenic strains of Aspergillusflavus to displace aflatoxin-producers during crop development. The displacement results in lower aflatoxin concentrations in harvested grain. The current study evaluated...

introduction: in respect of underground cultivation, production and consumption wheat is the major alimentary seed in iran. the contamination of wheat to fungi especially aspergillus flavous (the most important aflatoxin producer in nature) and aflatoxin is a risky factor to community health. the aim of this study was to identify aspergillus flavous and aflatoxins in the stored wheat of mazanda...
