1. Introduction Aflatoxins are undoubtedly the most studied mycotoxins in Mozambique, especially aflatoxin B 1 (AFB 1 ). This is due to records of local epidemiological associations between this toxin and hepatic cancer [1], and export restrictions of contaminated groundnuts and maize [2]. There are reports on fumonisins and other toxins [3,4], but these are few compared to the information on AFB 1 . Yet, there is still a need for surveys on...

1. Introduction Mycelial size is widely regarded as the “golden standard” for mold growth studies [1], regardless of if they are based on radius, diameter, perimeter, or area. However, this approach has some drawbacks: (1) molds do not stop growing if conditions allow; (2) the size does not tell much about the metabolism, especially in the field; (3) in closed systems, the growth in size is limited by the container and the mold takes its shape; (4) the growth in size...

1. Introduction In Uganda, maize (Zea mays L.) is one of the most important crops in terms of production, consumption, and income generation. Because of its relevance, maize was one of the food security crops–and the only cereal–selected by the Ministry of Animal Industry and Fisheries of Uganda to implement a 5-year, multi-million USD agricultural intervention as part of the Development Strategy and Investment Plan (DSIP) during 2010–2015 (MAAIF, 2010). The...

The presence of toxic chemicals in food, particularly in products intended for children’s consumption, is a matter of great concern to consumers and international health authorities 1 . According to the RASFF annual reports of the European Commission, around 45% of the informative notifications issued in recent years were related to the presence of chemical substances such as pesticides, biotoxins, veterinary drugs, food additives, etc. 2 . Among them, mycotoxins...

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 Mycotoxins are toxic secondary metabolites produced by filamentous fungi in crops or during storage, transport and processing of food and feed commodities, which pose serious health risks for both humans and animals [1]. The trend of mycotoxin contamination in food and feed has reached alarming levels. According to a report of the Food and Agriculture Organization of the United Nations (FAO), 25% of global agricultural products are contaminated by mycotoxins each...

1. Introduction The consumption of natural products, especially those derived from medicinal plants and herbs, is increasing worldwide, as plants have been used since ancient times to prevent or treat maladies in both humans and other animals. These medicinal plants are rich in several compounds with biological activities that are beneficial for consumers, such as anti-inflammatory, analgesic, antioxidant, and antimicrobial activities [1,2]. These biologically active chemicals...

In the first half of 2022, Life Rainbow mycotoxin analysis lab collected 161 feed samples of raw materials and feed mills in farms and analyzed. The survey provides essential information on the feed pollution situation of aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3) and deoxynivalenol (DON) in Taiwan. All the samples were analyzed using ELISA mycotoxin analysis kit. Results: The results show that 88.8% of feed was contaminated with aflatoxins;...

Introduction Coffee, due to its physiological effects and organoleptic characteristic is widely consumed as non-alcoholic beverage with high economic impact. Like other crops, coffee beans are also prone to microbial infections during production, processing and storage stages [1, 2]. Prevalence of toxigenic Aspergillus and Penicillium spp., on coffee beans has been reported in coffee growing as well as non-growing parts of the world [3, 4]. These fungal infections at favorable...

I. INTRODUCTION Mycotoxin-contaminated feeds are frequently reported to be more toxic for animals than their purified forms, indicating possible interactions with each other or with the micro-organisms in the animal’s gastrointestinal tract (JECFA, 2002) as bacteria (Galarza-Seeber et al, 2016). The gastrointestinal tract is the largest immune organ, where several immuno-regulatory mechanisms simultaneously defend the body (Belkaid & Hand, 2014). Yet, it is also home...

INTRODUCTION Coffee is one of the most appreciated and consumed beverages in the world (1); however, in its various states, it is susceptible to present a risk of contamination by mycotoxins (2). Mycotoxins are secondary metabolites produced by filamentous fungi that are present in agricultural products due to inadequate food handling and poor storage methods (3,4). Several toxigenic fungi such as Fusarium spp., Aspergillus spp., and Ochratoxigenic species have been found in...

1. Introduction Aflatoxin M1 (AFM1), it is one of five principal metabolites results from the hydroxylation process of Aflatoxin B1 (AFB1). Reaction of enzyme oxidase is associated to cytochrome P 450 of the microsomes within the hepatocytes [1–6]. During this oxidative process, AFB1 is successively transformed into two intermediates, Aflatoxicol (AFL) and Aflatoxicol M1, before turning into AFM1, and in this form it is excreted through milk or eggs [3]. Some...

1. Introduction Aflatoxin M1 (AFM1) is the main metabolite of Aflatoxin B1 (AFB1), which is one of the four most common variants of Aflatoxins (AFs) [1–6]. There is sufficient evidence for the carcinogenicity of AFM1 alone or mixed with AFB1 and Aflatoxin G1 (AFG1) [7], although of lower potency than AFB1 [8,9]. When cattle ingest food or feed contaminated by AFs, it is estimated that up to 6.2 % of the content of AFB1 is transformed into AFM1 and excreted in milk...

INTRODUCTION Impact of the presence of toxigenic fungi in the embryonic egg In practice, 100 % yield can seldom be achieved in egg incubation for “broiler” chicken production (Manders et al., 2021). There are many factors that affect the incubation process and it is essential to know how to do a good analysis of all the available data to know what the problem is and to propose “organic” alternatives that do not modify the percentage yield of...
