1. Introduction
The appearance of new transmittable plant diseases is determined by anthropogenic and conservational change, including changes in trade, land use, and climate [1–4]. The growth of infected plant material through trade in plant products, germplasm, grafts, and live plants has been recognised as the greatest contributing factor to the emergence of new plant diseases [5–7]. A pathogen may be introduced without disease emergence initially...

1. Introduction Mycotoxins are toxic metabolites produced naturally by some species of filamentous fungi, such as Aspergillus, Fusarium, and Penicillium [1,2]. Fungal growth can occur before or after harvest, during storage, or in foods, especially in environments with high humidity and temperatures, followed by mycotoxin production. Most mycotoxins are chemically sta-ble and persist after food processing [3,4]. The most investigated mycotoxins are aflatoxin B1 (AFB1),...

1. Introduction Mycotoxins are among the secondary metabolites released by molds, particularly fungi, which contaminate agricultural products pre-harvest, during harvest, and/or postharvest and mostly exhibit toxicity to animals and humans [1–3]. Common mycotoxins include aflatoxins, ochratoxins, zearalenone (ZEA), patulin, sterigmatocystins (STCs),citrinin, ergotamine, deoxynivalenol (DON), fumonisins, trichothecenes, etc. Human exposure to these mycotoxins can occur via...

Climate change threatens future food security due to the probable increase in temperature and changes in precipitation patterns which could affect the distribution of where different crops may be viably grown 1,2 . Land suitability and capability classifications are used to evaluate the best growing areas for specific crops and to identify factors that might limit their growth 3,4 . Key factors in determining these classifications include fluctuations in moisture...

Introduction The poultry industry in Nigeria is an essential subsector of agriculture that provides food, employment, and other economic resources for the country (Ezekiel et al. 2012a). Livestock production can be threatened when feeds are contaminated by fungi and their toxic metabolites. Several mycotoxins, including aflatoxins (AFs), cyclopiazonic acid (CPA ), fumonisins (FUMs ), nivalenol (N IV ) and zearalenone (ZEN) have been reported to contaminate poultry feed and their...

1. Introduction Mycotoxins are harmful secondary metabolites produced by fungi that contaminate a wide range of food and feed products [1–3]. Depending on the frequency of occurrence and/or the severity of the disease that they produce, mycotoxins belonging to the aflatoxin, ochratoxin, and Fusarium toxin groups exert great impacts on animal/human health as well as on global trade [2,4]. Aflatoxin B1 (AFB1), zearalenone (ZEA), ochratoxin A (OTA), and deoxynivalenol (DON)...

1. Introduction Fungi are the second largest group of eukaryotes that play a significant role in human health. The widespread prevalence of fungi in the environment and food chain makes them hazardous for humans. Mycotoxins contamination of agricultural produce is a serious threat to human health [1]. The ingestion of mycotoxins contaminated food, results acute and chronic toxicity to the humans and animals. Food and Agricultural Organization (FAO) suggested that about 25 % of...

1. Introduction Avena sativa, commonly known as oats, is a cereal belonging to the Poaceae grass family that has traditionally been used as animal feed, particularly for horses and dairy cows. In recent years, the beneficial nutritional and physiological effects of oat products have generated an increase in nutrition-conscious consumer demand. The characteristic feature of oat grains is the favourable profile of amino acids, vitamins, minerals, and essential unsaturated...

Introduction
Aflatoxins (AF) are a major concern in poultry production and public health because of serious economic losses and health problems. AF contamination causes reduced feed quality and reduced animal efficiency either through poor conversion of nutrients or problems such as reproductive abnormalities. Aflatoxicosis in poultry also causes listlessness, anorexia with lowered growth rate, poor feed utilization, decreased egg production and increased mortality....

INTRODUCTION As a fungal secondary metabolite of the Aspergillus species, aflatoxin B 1 (AFB 1 ) is known to be the most toxigenic mycotoxin (Yunus et al., 2011). Feed contamination with AFB 1 has been a major feed safety concern due to its negative effects on growth performance, production, hepatic functions, and immune system in many livestock species (Ledoux et al., 1999; Yarru et al., 2009; Andretta et al., 2011; Grenier and Applegate,...

1. Introduction Breeding for Fusarium head blight (FHB) resistance is the most effective means of providing useful protection of wheat [1,2]. It is well known that resistance to Fusarium graminearum and Fusarium culmorum is not race-specific [3–7]. Research has shown that in wheat, the resistance to different Fusaria is also species-non-specific, e.g., the genotypes, being resistant to F. graminearum, will also show resistance to other Fusarium spp. tested [8,9]. As...

1. Introduction Mixing of isolates is a general methodical procedure used to produce inoculum for artificial inoculation. In most cases, no reason is given as to why it is used. It is known that the isolates of the Fusarium spp. have a strong variability in aggressiveness [1–3]. As mixing in seedling tests strongly influences aggressiveness [1], it is important to know what the influence of mixing on the disease-causing capacity is. It is clear now that Fusarium...

1. Introduction Mycotoxins are toxic secondary metabolites produced by some filamentous fungi and whose presence has been detected mainly in agricultural products and processed food [1,2]. A recent review published by Eskola et al. [3] estimated that more than 60% of all crops around the world contain mycotoxins, and several classes can simultaneously be found in food. Contamination can happen at any stage of cultivation, harvesting, processing, or storage, when environmental...

1. Introduction Creatinine (2-amino-1-methyl-2-imidazoline-4-one) is the final metabolism product of creatine in mammals [1], which is excreted exclusively by the kidneys via glomerular filtration and, to a lesser extent, by tubular secretion [2]. Under physiological conditions, its excretion throughout the day is relatively constant, the amount of creatinine produced is proportional to the muscle mass of the individuals [3]. In contrast, urine production depends on the...

Introduction Mycotoxins are a large group of toxins produced by moulds and they can be very toxic for animals, plants and humans. Mycotoxins occur particularly in regions or countries with climates of high temperature and humidity or where there are poor crop harvesting and storage conditions, which encourage mould growth and mycotoxin development (25). The toxic effects of mycotoxins are mainly on liver and they cause teratogenic, mutagenic,...
