Crops contaminated with fungal mycotoxins such as aflatoxin B1 (AFB1) are often downgraded or removed from the food chain. This study aimed to evaluate the tolerance and accumulation of AFB1 in two insect species to determine whether they could be used to retain condemned mycotoxin contaminated crops in the food chain. First, instar black soldier fly larvae (Hermetia illucens, BSF) and yellow m...

Aflatoxins (AFs) are mycotoxins produced by some species of Aspergillus. In dairy cows, ingested AFB1 is metabolized into carcinogenic AFM1 which is eliminated through milk, thus posing a risk for consumer health. Here we describe the set, validation, and application of screening (ELISA) and confirmatory (HPLC) tests carried out on milk samples collected through official control of mycotoxin le...

Butylated hydroxytoluene pretreatment in the rat enhanced the total in vitro metabolism of aflatoxin B1 by the hepatic postmitochondrial fraction (S-9) and increased the formation of aflatoxin M1, aflatoxin Q1 and a metabolite tentatively identified as the aflatoxin-glutathione conjugate, the latter being the major metabolite produced. Addition of diethyl maleate, a glutathione depletor, to the...

Background: In Nigeria, there is paucity of information on exposure to aflatoxin by lactating women and children. Aflatoxin (AFs) are potent carcinogens that are produced as secondary metabolites of strains of Aspergillus parasiticus and Aspergillus flavus that grow on important food crops such as groundnuts, maize and other oilseeds .Present study reports on the aflatoxin exposure of lactating...

background aflatoxins are one of the most potent toxic substances that occur naturally. nowadays extensive attention has been taken to their existence in food and environment, as there is the possibility of harm to humans following chronic exposure to extremely low levels via food chain. aflatoxin m1 (afm1) is a hepatic carcinogenic metabolite found in the milk of lactating animals fed with con...

BACKGROUND Residents of Qidong, People's Republic of China, are at high risk for development of hepatocellular carcinoma, in part due to consumption of foods contaminated with aflatoxins, which require metabolic activation to become carcinogenic. In a randomized, placebo-controlled, double-blind phase IIa chemoprevention trial, we tested oltipraz, an antischistosomal drug that has been shown to...

-Aflatoxin BI was given by ip injection to year-old female guinea-pigs and 6 hr later aflatoxin B1 and its metabolites were recovered and isolated chromatographically. Approximately 14~ of the administered toxin was represented by the isolated compounds. Aflatoxin B1 and M1 each accounted for approximately 3 7o, and the remaining 94~ was a product that migrated with the solvent front in a chlor...

background: aflatoxin m1 (afm1) as a carcinogenic and toxic compound has considerable significance from public health viewpoint. the aim of this study was to determine the level of afm1 in pasteurized and uht milk in west-azerbaijan province of iran. methods: a total of 360 commercial milk samples including 220 pasteurized milk and 140 ultra-high-temperature (uht) milk were purchased randomly f...

background: the occurrence of aflatoxin m1 (afm1) in milk, especially breast milk, is a valuable biomarker for ex-posure determination to aflatoxin b1 (afb1). in the present study, the risk of exposure to afm1 in infants fed breast milk was investigated. methods: an enzyme-linked immunosorbent assay (elisa) was used for the analysis of afm1 in breast milk samples from 132 lactating mothers refe...
