AFRICAN JOURNAL OF BIOTECHNOLOGY 31/12/14 Determination of aflatoxin B1 in food products in Thailand. Aflatoxin B1 is a secondary metabolite of Aspergillus flavus and Aspergillus parasiticus.
It can be formed in commodities before and after harvest. This mycotoxin possesses a variety of toxic effects, potent carcinogen to both animal and human health. Aflatoxin B1 is generally found in feed and food stuff, such as cereal and all products derived from cereals, including processed cereals since it has been proven to be at least partly resistant to food processing methods. Hence, the aim of this study was to determine the possibility of contamination of aflatoxin B1 in food products in Thailand.
The 100 food samples were purchased from markets around Bangkok. Key words: Mycotoxins, aflatoxin B1, carcinogen.
FRONTIERS IN MICROBIOLOGY 12/08/14 Global health issues of aflatoxins in food and agriculture: challenges and opportunities. Aflatoxins are a group of polyketide mycotoxins that are produced mainly by members of the genus Aspergillus.
Production of these toxic secondary metabolites is closely related to fungal development (Keller et al., 2005; Jamali et al., 2012). Contamination of food, feed and agricultural commodities by aflatoxins poses enormous economic and serious health concerns because these chemicals are highly carcinogenic and can directly influence the structure of DNA. The resulting genetic defects can lead to fetal misdevelopment and miscarriages; aflatoxins are also known to suppress immune systems (Razzaghi-Abyaneh et al., 2013). In a global context, aflatoxin contamination is a constant concern between the 35N and 35S latitude where developing countries are mainly situated. With expanding boundaries of developing countries, aflatoxin contamination has become a persistent problem to those emerging areas (Shams-Ghahfarokhi et al., 2013).

Introduction The relatively recent outbreak of aflatoxins risk contamination in Europe has driven the EU researchers to investigate on this topic usually confined to tropical and sub-tropical areas.
In this respect, aflatoxins and aflatoxigenic fungi are by far the most serious, dangerous and studied mycotoxin issue in agricultural products. Aflatoxins are secondary metabolites synthesized by several Aspergillus species and are highly toxic to humans and animals when ingested at high concentrations. They may cause severe liver damage accompanied by jaundice, hepatitis and death, especially in developing countries (Probst et al., 2007).
In addition, they are genotoxic, carcinogenic, and teratogenic for both humans and animals.

JOURNAL OF STORED PRODUCTS AND POSTHARVEST RESEARCH - JUNE 2015 - Aflatoxin management in Northern Ghana: Current prevalence and priority strategies in maize (Zea mays L) The production and utilization of maize have increased tremendously across all regions of Ghana in recent times.
However, aflatoxin (AF) contamination in grain maize has remained a critical food safety concern. The study was conducted in 6 districts in the Upper East and Upper West regions of Ghana to assess farmers’ knowledge on AF, and determine AF levels under farmer storage conditions. A total of 240 respondents from 24 communities were covered using a structured questionnaire, and 240 maize samples were obtained for AF analysis. All the samples were collected within 2 to 6 weeks after harvest for AF analysis using the Indirect Enzyme Linked Immunosorbent Assay method. Overall, 78% of the respondents were aware of AF although majority (68.1%) did not perceive AF as a major food safety issue. Key words: Aflatoxins, food safety, maize, on-farm storage, consumer perception.

Several of the food crops grown in Africa, such as cassava, chili, groundnuts, maize, rice, sorghum, teff, and major cash crops such as coffee, cocoa, tea and sugarcane have been found to be contaminated with these dangerous toxins. They have also been found in processed foods such as peanut butter and foods from animal sources like egg and milk.

Sequestri di Asl e Nas anche in Veneto. Si sono intensificati i controlli ufficiali per la ricerca di aflatossine nel latte e nei mangimi.
Le recenti condizioni climatiche, che si sono verificate in Italia nel corso dell’estate 2015, caratterizzate da una prolungata siccità, hanno determinato una accresciuta contaminazione da aflatossine nelle produzioni di mais e nelle produzioni di latte che, in alcuni casi, ha superato i limiti fissati dalla normativa comunitaria. L’incremento di aflatossine nel mais può avere ripercussioni di natura sanitaria sia dirette, sul mais ad uso alimentare, che indirette, attraverso l’uso dello stesso nei mangimi e la conseguente presenza di aflatossina M1 nel latte, oltre i livelli consentiti.

Introduction Aflatoxins (Aspergillus flavus and Aspergillus parasiticus) are widely recognized as a major health problem, especially in hot, humid countries.
This is a particular serious problem in such crops as maize, rice, peanuts, tree nuts, and dried fruits. Aflatoxin production normally occurs in the field, particularly when stimulated by drought, stress, and high temperatures or during prolonged drying. Aflatoxin-producing molds grow exponentially in conventional multi-month storage as a result of a combination of heat and high humidity (Hell et al., 2010). Figure 1 (Villers et al., 2008) shows the graphic relationship between mold growth and relative humidity at equilibrium. Figure 1. Table 1. In East Africa post-harvest losses in maize, as shown in Figure 2, often reach 25%, or more (World Bank Report, 2011). IFPRI - NOV 2013 - Codex Standards: A Global Tool for Aflatoxin Management.

Finally the section entitled Approaches for Prevention and Control of Aflatoxins on Crops and on Different Foods, describes actions to prevent and mitigate the genotoxic effect of one of the most conspicuous aflatoxins, AFB1.

Following reports from farmers associations on the aflatoxins contained in animal feedstuffs, maximum permissible levels of aflatoxins has become a topic of discussion.
Aflatoxin is a mycotoxin produced by microscopic fungi of the genus Aspergillus which grow on a large number of vegetable substrates such as cereal crops (particularly maize) and semi‐oleaginous crops (such a peanuts), spices, grain, nuts and dried fruit, both during growing and at harvesting and on storage. Aflatoxin B1 (AFB1) is especially toxic, which is why the EU has set maximum permissible limits for it as a precautionary measure. Those limits have been set both for foodstuffs intended for humans and for the the various raw materials used in the production of animal feeds.

Historically, the exposure of aflatoxin in Malaysia can be dated in 1960s where an outbreak of disease in pig farms caused severe liver damage to the animals.
Later, an aflatoxicosis case in Perak in 1988 was reported and caused death to 13 children, as up to 3mg of aflatoxin was present in a single serving of contaminated noodles. Since then, extensive research on aflatoxin has been conducted in Malaysia. The food commodities such as peanuts, cereals, spices, and their products are the main commodities commonly found to be contaminated with aflatoxin.

JDLE 31/07/13 L’arachide indienne sous contrôle accru de l’UE (aflatoxines) Un produit sous haute surveillance L’arachide indienne constitue l’une des denrées alimentaires d’origine non animale les moins souvent conformes aux normes de l’Union européenne, avec 44,1% des échantillons analysés dépassant le seuil autorisé d’aflatoxines, ce qui lui vaut un durcissement des contrôles. Au-delà des contrôles de routine, certains aliments d’origine non animale font l’objet de contrôles renforcés à leur entrée dans l’UE, en raison d’un risque sanitaire spécifique. Et ce en vertu du règlement n°669/2009, qui prévoit que les denrées en question entrent toutes par des points d’entrée désignés  et qu’une proportion d’entre elles (10%, 20% ou 50% selon l’acuité du risque) soient analysées de manière physique ou biologique.

This version replaces the previous one/s. Aflatoxins are produced by moulds that are especially found in areas with hot, humid climates. They are most likely to contaminate tree nuts, ground nuts, figs and other dried fruits, spices, crude vegetable oils, cocoa beans and maize. Because aflatoxins are considered to be genotoxic and carcinogenic, it is not possible to identify an intake without risk, and the European Union (EU) introduced regulations for these toxins in 1998, at levels considered to be as low as reasonably achievable.
