I. INTRODUCTION The quality of poultry feed and litter are important for maintaining and improving poultry production. Poultry feed (raw materials and formulated diet) is highly variable and large safety margins are needed to buffer the nutritional variability in feed ingredients when formulating diets (Moss et al., 2021). Feed ingredients delivered to feed mills are not comprehensively analysed using current methods (i.e., wet-chemistry and NIR). This is because the large quantities...

Deoxynivalenol (DON; vomitoxin) is a trichothecene mycotoxin that is produced by Fusarium graminearum and is prevalently found in grains such as wheat, corn, barley and their by-products. DON mainly affects the health of monogastric animals, particularly pigs and poultry, through contaminated feedstuffs. Animal study ...

INTRODUCTION Fusarium verticillioides has long been known to be a causal agent of maize ear rot but has received more attention since the discovery that fumonisins, the mycotoxins it produces, can accumulate in maize kernels (Gelderblom et al., 1988). Fumonisin consumption can lead to serious disorders in humans and animals; for example, leukoencephalomalacia in horses and pulmonary edema in swine, both are accompanied by injuries to the liver and heart; hepatic necrosis and,...

1. Introduction Mycotoxins are naturally occurring secondary metabolites produced by various genera of molds, such as Aspergillus, Fusarium, Penicillium, and Alternaria. About 400 mycotoxins have been identified, with some of the most important ones being aflatoxins B1 (AFB1), aflatoxin B2 (AFB2), Ochratoxin (OTA), and deoxynivalenol (DON) [1]. The consumption of mycotoxin-contaminated foods can have serious health consequences, being potentially fatal, depending on the specific...

1. Introduction As Thomas Edison once said, “The doctor of the future will no longer treat the human frame with drugs, but will rather cure and prevent disease with nutrition” [1]. Nowadays, one in every five deaths across the globe are attributable to a suboptimal diet, more than other risk factors, such as tobacco [2]. A multitude of chronic diseases related to an improper diet have emerged; thus, more and more experiments regarding the quality of food as a part of...

I. Introduction Immediately after birth, or hatch in birds, the initial inoculum shapes the gut microbiota for life. The first bacteria to settle in the intestine can attach to epithelial cells with no competition, rapidly establish, grow, and set the intestinal environment to suit their own needs (Stecher and Hardt, 2011; Edwards, 2017). The first bacterial settlers have the most substantial influence on developing the host's immune system and overall ability to thrive (Stecher...

1 Introduction Mycotoxins are toxic metabolites produced by fungi. The fungi grow on food commodities such as cereals, coffee, fruits, nuts, oilseeds, and spices when there are favorable conditions (Awuchi et al., 2021). Currently, over 400 mycotoxins have been recorded, and 25% of food has been shown to be contaminated. (Tola and Kebede, 2016; Escrivá et al., 2017); however, only a few are of concern from a food safety perspective: Aflatoxins (AFs), Fumonisins (FBs),...

INTRODUCTION Corn is one of the major components of poultry feed, and up to 65% of finished poultry feed can be comprised of corn and corn byproducts (Alqaisi et al., 2017). Poultry diets are often contaminated with more than one mycotoxin. Fumonisins (FB) and deoxynivalenol (DON) are secondary mycotoxin metabolites produced by Fusarium verticillioides and Fusarium graminearum, respectively (Glenn, 2007). According to the 2021 survey by Biomin, FB and DON are the most prevalent...

INTRODUCTION Mycotoxins are toxic secondary metabolites produced by filamentous fungi on agricultural products, which cause acute or chronic toxic effects in farm animals and humans called mycotoxicosis (Schirone et al., 2016; Du et al., 2017). The contamination of agricultural products with fungi occurs during pre-and post-harvesting stages due to inappropriate and unhygienic practices (Bernhoft et al., 2012). The Food and Agricultural Organization (FAO) of the United Nations...

INTRODUCTION The lifestyles of Aspergillus species associated with plants range from saprophytes and symptomless endophytes to weak and opportunistic phytopathogens. The shift between these lifestyles is the result of global transcriptome changes, primarily affecting secondary metabolite (SM) production (e.g., Reverberi et al., 2013). The principal and well-known mycotoxins produced by the Aspergilli are ochratoxin A (OTA) and aflatoxins (AFs), as well as less-prominent toxins like...

INTRODUCTION Fusarium head blight (FHB) is one of the major economically important fungal diseases in wheat, barley, corn, and other small grains worldwide. Wheat yield losses of up to 50% have been reported in North America due to FHB (McMullen et al., 1997; Goswami and Kistler, 2005). One of the major concerns of FHB is the contamination of infected grains with Fusarium mycotoxins. Fusarium mycotoxins represent the largest group of mycotoxins, which contains more than 140 known...

INTRODUCTION Mycotoxins are secondary metabolites that are produced by microfungi which are capable of causing disease and death in humans and other animals (Bennett and Klich, 2003). According to a risk assessment overview provided by the European Food Safety Authority (EFSA) (EFSA CONTAM Panel) related to the main contaminants in food and feed, mycotoxins represented 15% of the overall risk for human and animal health, for the period between 2003 and 2012 (EFSA,...
