INTECH 23/01/13 Aflatoxins: Risk, Exposure and Remediation

Introduction Aflatoxins family includes a great number of lipophilic molecules produced by aerobic microscopic fungi belonging to the genus Aspergillus. The chapter describes their chemical structure, chemical and physical properties, and aspects related to their presence in food and commodities. Aflatoxins presence in food is considered a real and severe risk to consumers for their toxicity. Aflatoxins levels and frequency of foods natural contamination as reported in the scientific literature are briefly analyzed. 2.

Aflatoxins were isolated and characterized after the Turkey X desease, that caused the death of more than 100.000 turkey poultries due to the intake of a contaminated peanut meal produced in South America starting from contaminated raw material (Blout, 1961; Goldblatt, 1969).

Introduction Aflatoxin B1 (AFB1), an important mycotoxin, is first identified in animal feed in 1961 due to the death of 100,000 turkeys in the UK where these turkeys were feed using the peanut powder with the high concentration of AFB1.

FRONTIERS IN PHARMACOLOGY 01/09/17 Development of a UPLC-FLD method for detection of aflatoxin B1 and M1 in animal tissue to study the effect of curcumin on mycotoxin clearance rates

In this study, an ultra-high performance liquid chromatography linked with fluorescence detection (UPLC-FLD) method was optimized and validated. In addition, we investigated for the first time, the influence of curcumin on residue depletion of AFB1 and AFM1 in liver, kidney and muscle tissues of broiler chickens and estimated a necessary clearance time required for AFB1 and AFM1 residues. The results showed that the average recoveries of AFB1 varied in liver, kidney and muscles between 82.32-85.56%, 85.34-88.45% and 84.88-89.73% respectively, while the average recoveries of AFM1 in liver, kidney and muscles varied between 92.17-95.03%, 94.12-97.21% and 95.32-98.51%, respectively. The detection limit of aflatoxin B1 was 0.008 ng/ml, while for aflatoxin M1 was 0.003 ng/ml. Journal of Food Research; Vol.6, No.2; 2017 Food Safety and Aflatoxin Control.

Introduction Mycotoxins are chemically and biologically active secondary metabolites (of molecular weight ≤ 700), produced by filamentous fungi that readily colonize crops in the field or after harvest (Richard, 2007; Turner et al., 2010).

FRONTIERS IN MICROBIOLOGY 14/07/16 Structural Analysis and Biological Toxicity of Aflatoxins B1 and B2 Degradation Products Following Detoxification by Ocimum basilicum and Cassia fistula Aqueous Extracts

Currently, more than 400 compounds are recognized as mycotoxins, among them aflatoxins have assumed significance due to their deleterious effects on humans, poultry, and livestock (Sur and Celik, 2003; Wild and Montesano, 2009). Aflatoxins are group of heterocyclic, oxygen containing mycotoxins that possess the bisdifuran ring system. About 18 different types of aflatoxins are identified among them most commonly occurring ones are aflatoxins B1, B2, G1, G2, M1, and M2 which are mostly produced by Aspergillus flavus and A. parasiticus.

Aflatoxins were first identified as the portable toxin that destroyed more than 100,000 turkey poults (turkey X disease) in England in the early 1960s (Kuhn and Ghannoum, 2003).

CGIAR 11/08/16 Special issue: Aflatoxins in eastern Africa

The special issue, Volume 16 No.3, was compiled by the International Livestock Research Institute (ILRI) with contributions from several A4NH researchers, and contains 12 peer-reviewed articles on a range of topics related to understanding and addressing aflatoxin contamination in countries throughout eastern Africa. Under the flagship on agriculture associated diseases, A4NH research offers insight into the most effective ways to control food safety risks, such as aflatoxin contamination. This work includes coordinating closely with groups committed to addressing this problem, such as the Partnership for Aflatoxin Control in Africa (PACA), as well as support for scaling proven interventions to prevent contamination in the first place, including the aflasafe biocontrol method.

Southern Regional Research Center, United States Department of Agriculture – Agricultural Research Service, New Orleans, LA, USA Aspergillus flavus is a diverse assemblage of strains that include aflatoxin-producing and non-toxigenic strains with cosmopolitan distribution.

FRONTIERS IN MICROBIOLOGY 10/02/14 Non-aflatoxigenic Aspergillus flavus to prevent aflatoxin contamination in crops: advantages

The most promising strategy currently being used to reduce preharvest contamination of crops with aflatoxin is to introduce non-aflatoxin (biocontrol) A. flavus into the crop environment. Whether or not introduction of biocontrol strains into agricultural fields is enough to reduce aflatoxin contamination to levels required for acceptance of the contaminated food as fit for consumption is still unknown. There is no question that biocontrol strains are able to reduce the size of the populations of aflatoxin-producing strains but the available data suggests that at most only a four- to five-fold reduction in aflatoxin contamination is achieved.

QUEENSLAND GOVERNMENT - Aflatoxin in Peanuts. Peanuts affected by aflatoxin Aflatoxin is the name for a group of toxins (carcinogenic compounds) that are produced by two fungi called Aspergillus flavus and Aspergillus parasiticus.

These toxins occur naturally and have been found in a wide range of commodities (including peanuts) used for animal and human consumption. Depending on the levels, the toxins can severely affect the liver and they are a known human carcinogen (i.e. causes cancer). In many developing countries aflatoxin is a major health risk to humans and animals due to the high levels of contaminated product consumed. In Australia aflatoxin is not a health risk because of the thorough testing done at various stages along the food chain and the effective technology and procedures employed by agribusinesses to eliminate contaminated product.
