Mycotoxins in food
Welcome to the page about Mycotoxins in food of Engormix; a source of knowledge on Mycotoxins in food.
INTRODUCTION The Food and Agriculture Organization (FAO) estimated that 25% of global food crops are contaminated with mycotoxins 1 . Recently, the prevalence of the mycotoxins detected in food and feed crops was reported to be up to 60–80%2 . Aflatoxins are the major ones among all mycotoxins and produced by Aspergillus spp. upon and after infection of crops. They are genotoxic and carcinogenic to animals and humans 3–6 . From the different...

Introduction Aflatoxins are toxic, secondary metabolites synthesized by some fungi species in the genus Aspergillus, mainly those belonging to the species A. flavus, A. nomius, and A. parasiticus (Ismaiel et al., 2020). Aflatoxins are considered the most important mycotoxins, given their carcinogenic and hepatotoxic effects on animals and humans (Bhat et al., 2010). Among several types of aflatoxins, the most frequent ones found as natural contaminants of foodstuffs are aflatoxins...

Poultry researchers show there’s no safe amount of moldy corn
Poultry scientists are taking a close look at moldy corn in an effort to better protect animal and human health. In a recent study, published in Poultry Science ® , researchers measured bird performance and examined mycotoxin levels when laying hens were fed different amounts of moldy corn.

In 2022 mycotoxins annual survey, Life Rainbow Biotech randomly collected 342 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3) and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit. Results: From January to December 2022, the import volume of feed corn was 4,383 thousand tons, and Brazil and Argentina is 32.05% and 31.27%, followed by South Africa...

1. Introduction Mycotoxins are secondary metabolites produced by specific fungi that are natural contaminants of foods [1]. At appropriate ambient temperature and humidity conditions, mycotoxins can be found at any stage of the production chain. However, the fungi presence does not imply mycotoxin formation [2]. Upon ingestion by ruminants, aflatoxin B1 (AFB1) is partially destroyed in the rumen, whereas the absorbed AFB1 rapidly undergoes metabolic processes in the liver...

Aflatoxins are fungal metabolites—mainly produced by Aspergillus flavus and Aspergillus parasiticus living in soil—that contaminate crops throughout growth, harvest, storage, transportation, and processing. Aflatoxin B1 is not only the most potent natural carcinogen known, but also the most commonly produced toxic strain. As of 2010, roughly 5 billion people worldwide were estimated to be exposed to high levels of aflatoxins. High consumption levels can result in aflatoxicosis,...

INTRODUCTION Aflatoxins (AFs) in food and feed are recognized as a public health problem of considerable importance. Williams et al. (2004) estimated that 4.5 billion of the world’s population is exposed to AFs. Because security blankets in crops at pre-harvest and post-harvest level are not as strict as in developed countries, populations of developing countries are the most susceptible to aflatoxicosis illness (Williams et al., 2004). The same problem occurs with milk...

Genetically engineering Aspergillus species to delete certain proteins stops mycotoxin production
By Deborah Balthazar
Food contaminated with fungi can be an inconvenience at best and life-threatening at worst. But new research shows that removing just one protein can leave some fungal toxins high and dry, and that’s potentially good news for food safety.
Some fungi produce toxic chemicals called...

1. INTRODUCTION Global programs are involved in addressing food and nutrition in the developing countries (WHO 2018). Improving nutrition is undoubtedly a challenging interdisciplinary proposition that involves availability and consumption of nutritious food. Covid-19 pandemic has further exposed the vulnerability of food systems in the low- and middle-income countries (LMICs). Green revolution was one milestone towards achieving food security when high yielding crop...

Abstract Kemin India has conducted a detailed survey to understand the mycotoxin prevalence pattern in poultry feed and feed raw materials from various regions in India. The study was carried out from Jan 2010 to July 2010 and comprised of 400 samples. The study revealed that, 393 out of 400 samples tested were contaminated with one or more mycotoxin i.e. 98% of sample collected was contaminated with mycotoxin. Study has also revealed that all...

1. Introduction Mycotoxins are secondary metabolites produced naturally by certain filamentous fungi that can be found, usually at low concentrations, in a wide range of food matrices such as cereals, nuts, herbal teas, wine, coffee or species. Aspergillus, Penicillium, Alternaria, Fusarium, and Claviceps genus constitute the main mycotoxins producers [1,2]. Mycotoxin exposure via food and feed may produce several adverse health effects, such as carcinogenicity, immunotoxicity,...

1. Introduction Ochratoxin A (OTA) is one of the several fungal mycotoxins that have aroused significant public concern worldwide. The disease caused by OTA exposure is known as ochratoxicosis , and the primary target is the kidney. Epidemiological studies show that OTA may be involved in the pathogenesis of different forms of human nephropathies, including kidney cancer [1–3]. Tumor incidence data from long-term animal studies also provide reasons for...
