AbstractPregnant women and their developing fetuses are vulnerable to multiple environmental insults, including exposure to aflatoxin, a mycotoxin that may contaminate as much as 25% of the world food supply. We reviewed and integrated findings from studies of aflatoxin exposure during pregnancy and evaluated potential links to adverse pregnancy outcomes. We identified 27 studies (10 human cros...

The saprophytic soil fungus Aspergillus flavus infects crops and produces aflatoxin. Pichia anomala, which is a biocontrol yeast and produces the major volatile 2-phenylethanol (2-PE), is able to reduce growth of A. flavus and aflatoxin production when applied onto pistachio trees. High levels of 2-PE are lethal to A. flavus and other fungi. However, at low levels, the underlying mechanism of 2...

Administration of[3H]aflatoxin B2 (2,3-dihydroaflatoxin B1)(AFB2) to male rats resulted in levels of hepatic DNA- and ribosomal(r)RNA-aflatoxin adducts that were about 1% of those for rats given [3H]aflatoxin B1(AFB1). The levels of hepatic protein-aflatoxin adducts were 35 to 70% as great for AFB2-treated as compared to AFB1-treated rats...

A survey was conducted in the five rice-growing regions in Guyana to determine the presence of aflatoxins in multiple fractions of rice in June/October 2015 growing season. The fractions were paddy, steamed paddy, cargo rice, white rice and parboiled rice. Samples were analyzed by High Performance Liquid Chromatography. A subset of the samples was further analyzed by enzyme-linked immunosorbent...

Corn is the main component in manufacture of feed which functions as an energy source for poultry and ruminants. Requirements quality corn a ingredient are regulated Indonesian National Standard (SNI) includes moisture content, damaged seeds, mouldy foreign matter aflatoxin. The purpose this reserch was to evaluated analyzed whether it accordance with SNI 2020. In research, secondary data used ...

Tolnaftate [2-napthyl-N-methyl-N-(m-tolyl)thionocarbamate], an antifungal drug, is widely used to control superficial fungal infections in humans and other animals. In this study the effect of tolnaftate on aflatoxin biosynthesis by Aspergillus parasiticus NRRL 3240 was investigated. Tolnaftate changed the morphology of A. parasiticus to yeastlike forms and inhibited aflatoxin formation. The fo...

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 testing of food collected from the affected area revealed high levels of aflatoxin, suggesting that the outbreak was caused by afla-toxin poisoning, as was a pre...

BACKGROUND Aflatoxin M1 (AFM1) is the principal hydroxylated AFB1 metabolite present in milk of cows fed with a diet contaminated with AFB1and excreted within 12 hours of administration of contaminated feeds. OBJECTIVE This study was initiated to assess the knowledge and practices of urban dairy farmers and feed millers about aflatoxin in feeds and milk, determine the prevalence and quantify ...

Variance and performance of two sampling plans for aflatoxins quantification in maize were evaluated. Eight lots of maize were sampled using two plans: manual, using sampling spear for kernels; and automatic, using a continuous flow to collect milled maize. Total variance and sampling, preparation, and analysis variance were determined and compared between plans through multifactor analysis of ...

The aim of this study was to evaluate fungi and contamination levels of aflatoxin B(1), ochratoxin A, fumonisin B(1), and zearalenone in raw materials and finished feed intended for sows at different reproductive stages. Total fungi, Aspergillus, Penicillium, and Fusarium species occurrence, were examined. Aspergillus flavus, A. niger aggregate spp., and F. verticillioides were the prevalent sp...
