Mycotoxins are toxic substances produced naturally by filamentous fungi as secondary metabolites that can be found in food for humans and feed for livestock. Cereals, nuts, corn, and rice can be contaminated in the field during harvest or storage, making them a common source of contamination.
Most mycotoxins have been shown to be toxic, nephrotoxic, hepatotoxic, carcinogenic, immunosuppressive, and mutagenic in animal studies, and they pose a serious threat to human and animal health. Mycotoxins that have been chemically characterized and are currently the subject of research because of their demonstrated potential toxicity are described in this review.

Major mycotoxins that pose a risk to human and animal health Aflatoxins Aflatoxins are difuranocoumarin derivatives that are produced in a variety of food, including maize, groundnuts, rice, sorghum (Kew, 2013), pistachio, groundnuts, tree nuts (almonds,

MECHANISMS OF TOXICITY AND EFFECTS Aflatoxins are the most researched group of mycotoxins due to their carcinogenic and toxic effects in laboratory animals and livestock (Jha et al., 2013; Rotimi et al.,
2017), as well as their acute and chronic hepatocarcinogenic and toxicological effects in human beings (Asim et al., 2011; Kew, 2013). These ROS target cellular DNA, RNA, Aflatoxin toxicity arises mainly from

Hepatotoxicity
The metabolism of aflatoxins occurs mainly in the liver under the action of cytochrome P450s into electrophilic, reactive epoxide which, in turn, binds to DNA, RNA, and cellular macromolecules in the liver (Abrar et al.,
2013). Aflatoxins are usually associated with the development of hepatocellular carcinoma (HCC) in humans due to their mutagenic and carcinogenic properties.

Fumonisins Fumonisins are produced mainly by Fusarium verticillioides (also known as Fusarium moniliforme), Fusarium proliferatum, Fusarium nygamai, and other Fusarium species, such as Fusarium anthophilum, Fusarium dlamini, Fusarium napiforme, Fusarium subglutinans, Fusarium polyphialidicum and Fusarium oxysporum (Scott, 2012). There are 16 known types of Fumonisins, referred to as B1 B1 (FB1, FB2, FB3 and FB4), A1, A2, A3, AK1, C1, C3, C4, P1, P2, P3, PH1a and PH1. They are usually found in corn and corn-based foods (Marasas, 2001).
FB1 is the most commonly found in a list of food and feedstuff other than corn, such as rice, sorghum, beer, triticale, cowpea seeds, beans, soybeans, and asparagus (Scott, 2012).
MECHANISMS OF TOXICITY AND EFFECTS FB1 has a neurotoxic effect in equines as

Trichothecenes are toxic secondary metabolites produced in host plants, food, and other organic matrices by several fungal genera, including
Fusarium, Microcyclospora, Myrothecium, Peltaster, Spicellum, Stachybotrys, Trichoderma, and Trichothecium. Among them, Fusarium trichothecenes are of most significant concern to food and feed safety (Proctor et al., 2018). There are more than 150 toxins belonging to the trichothecenes family, but the most important ones are deoxynivalenol (DON), nivalenol (NIV), toxin T2, toxin HT2 and diacetoxyscirpenol (DAS) (Yang et al., 2015). Like most mycotoxins, they are a significant food safety concern because of the harmful effects they induce from acute and chronic exposure to them (Sobrova et al., 2010). DON is the most commonly found trichothecene in cereal grains (Tian et al., 2016).
MECHANISMS OF TOXICITY AND EFFECTS Trichothecenes are known for their capacity to

Its chemical structure is similar to naturally occurring estrogen and it exerts its action by acting as an endocrine-disrupting compound (EDCs) (Rogowska et al., 2019), potentially changing the functions of the endocrine system in living creatures and causing adverse health effects. In fact, they are known to prompt alterations in hormonally monitored physiological functions (homeostasis, growth, development, and reproduction) (Kar et al.,2021).

In fish, several studies reported the effect of zearalenone on reproductive performance, including impaired reproduction of rainbow trout and induced high sperm concentration and high plasma vitellogenin levels in males, and induced early ovarian development in females (Woźny et al., 2020).

arises because it is a xenoestrogen and EDC. Estrogens not only function as reproductive hormones. They also have non-reproductive functions, also affecting immune functions. In this respect, estrogens act on immune cells via estrogen receptors (ERs) which enable them to act either in an immunomodulatory (Islam
et al., 2017) or immunosuppressive way (Abbès et al., 2013; Zahran et al., 2021).
Ochratoxins Ochratoxins are dihydroisocoumarin bonded to phenylalanine pentaketide metabolites. They are classified as ochratoxin A (OTA), produced by Aspergillus ochraceus, and ochratoxin A, B, and C, produced by other Aspergillus and Penicillium species (Marroquín-Cardona et al., 2014). Ochratoxins have been found to contaminate various foods like grains, rice, wheat, dried fruit, coffee, cocoa, wine, beer, and foods of animal origin, particularly pork (Kumar et al., 2020).
OTA is the most predominant ochratoxin found in food and feed across the world, and it is the most toxic form comprising significant risk to human and animal health.

CONCLUSIONS Toxigenic secondary fungal metabolites, known as mycotoxins, are regarded as a threat to human health and food safety.
Due to their presence in a wide range of agricultural and food products, they continue to pose a serious threat to the health of animals and humans alike.
This article summarizes the major mycotoxins and their impact on animal and human health. In addition to this, methods used to decontaminate feed and feedstuffs are briefly discussed. Establishing a strategy for regular analysis and monitoring of mycotoxins levels to ensure food safety is essential for the future.
