The so called Mycotoxins are not a new subject to Indian poultry industry. Perhaps, it is not an overstatement to say that Indian poultry feed millers, integrators and farmers understand mycotoxin challenges much better than their counterparts from the other countries. This is due to the extensive applied research carried on mycotoxins in poultry as well as high occurrence of aflatoxicosis in the field. Mycotoxins are secondary metabolites of molds and their presence in the raw...

Scientists have looked at mycotoxin issues in the cereals sector in Ireland to help better protect consumers.
Ireland is an important producer of oats and barley. While some of the output is used as animal feed, a significant proportion is used in the food and beverage industries.
Chris Elliott, an ex-professor of Food Safety at the Institute for Global Food Security at Queen’s University Belfast, and a team of researchers have undertaken the work. It looked at the...

INTRODUCTION Mycotoxins are substances that occur naturally in the environment (1, 2). In addition to mycoestrogens such as zearalenone (3, 4), selected trichothecenes, including DON and/or its metabolites (but in vitro), can affect steroidogenesis (2) and changes in gene expression, which suggests that these compounds could disrupt hormonal homeostasis (1). Deoxynivalenol (DON), a polar organic compound produced mainly by Fusarium graminearum and Fusarium culmorum (5), is...

1. Introduction Aflatoxin contamination in foods, as well as in livestock and poultry feeds, is a major global concern due to its carcinogenic and immunosuppressive properties [1,2]. The ingestion of an aflatoxin-contaminated diet can lead to acute and chronic aflatoxicosis in both humans and animals. Chronic aflatoxicosis can result in hepatocellular carcinoma, cirrhosis, and impaired immunity. Acute aflatoxicosis is characterized by symptoms like high fever, vomiting, liver...

1. Introduction Corn ranks among the most globally cultivated cereals, with the production of more than 1200 million tons in the 2022/2023 harvest, mainly concentrated in the United States, China, and Brazil [1]. In Brazil, corn is the second most produced grain, following soybeans. For the 2023/2024 harvest, the estimated production in Brazil will exceed 118 million tons [2]. In the Brazilian market, the diversity of corn cultivars is substantial, whereby 98, 259, and 98...

This study was investigating the effects of a defined concentration of Fusarium mycotoxins, deoxynivalenol (DON) and zearalenone (ZON) incorporated into feeds on growth performance of pigs and the alleviating effects of a mycotoxin degrading enzyme (MDE) on the toxicity of Fusarium mycotoxins. A total of 48 weaning pigs was randomly allotted to four treatments for a 6-week challenged trial. The MDE product was a kind of mycotoxin degradation enzyme with esterase, epoxidase and...

Mycotoxins are produced by fungi and can lead to sickness in humans and animals, which explains why testing for them in crops, feeds, and food products is so important and is often a regulatory and customer requirement. Fortunately, testing technologies have evolved from slow, tedious, and complicated to smart, fast, and data connected. Tests vary in their performance capabilities and suitability for field, process, or lab environments. With a number of different options, you may be...

1. Introduction Fungi are major pathogens for plants, causing significant economic losses. Fungal infestation of crops at the pre- and post-harvest stages is also a risk for animal health, as they produce secondary metabolites with a wide range of biological activities; some are severely toxic to humans and animals. These toxic metabolites are commonly denoted mycotoxins, and their adverse health effects are described as mycotoxicosis to differentiate their pathogenesis...

Introduction Mycotoxins are secondary metabolites in certain molds that grow in raw material feed or commercial feed [1]. Mycotoxins have been reported to cause economic loss, disease in livestock and humans, and even death [2]. Five mycotoxins, aflatoxin, fumonisin, ochratoxin, trichothecene and zearalenone, have been reported to be dangerous to the body. Aflatoxins and ochratoxins are examples of mycotoxins whose toxicity levels are higher than others [3]. Aflatoxins and...

The continuous pursuit of a sustainable food system remains a global priority, with increased food security and minimization of postharvest loss as primary objectives. This is a critical issue, as recent estimates from the Food and Agriculture Organization (FAO) Reports on the State of Food Security and Nutrition in the World 2023 indicate that hunger affected a staggering number of individuals ranging from approximately 691 million to 783 million people in 2022, with an approximate midrange...

1 - INTRODUCTION Fusarium graminearum (teleomorph Gibberella zeae) is an ascomycete fungal pathogen and the main causative agent of Fusarium head blight (FHB), or scab disease, on wheat. F. graminearum infects wheat floral tissues at flowering (anthesis), secreting many cell wall-degrading enzymes (CWDEs), other proteins and metabolites as well as mycotoxins that contaminate the developing grain, rendering it unsuitable for both human and livestock consumption (McMullen et al.,...

Introduction Mycotoxins are secondary metabolites produced by filamentous fungi of Aspergillus, Fusarium and Penicillium species (31). These toxic metabolites are often found in grains and a substantial percentage of animal feed (18). The most common mycotoxins harmful to animal health are aflatoxin B1 (AFL B1), zearalenone (ZEN), deoxynivalenol (DON), fumonisins B1 and B2 (FB1 and FB2), ochratoxin (OTA) and T-2 toxin (T-2) (6). Different mycotoxins induce different effects on animal...

Introduction Wheat grains are important staple foods consumed worldwide. They are used as animal feeds, ingredients in food processing, or in the brewing industries (Giraldo et al. 2019). However, pre-and post-harvest colonisation by mycotoxigenic fungi and mycotoxins can occur depending on pre-harvest weather conditions and whether effective drying regimes have been applied for safe storage (Aldred and Magan 2004). Fusarium graminearum is predominantly responsible for...
