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....
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 Fusarium head blight (FHB) is a devastating fungal disease that affects wheat and other small-grain cereals worldwide, caused by several species belonging to the genus Fusarium. Besides causing significant yield losses and reducing grain quality [1], these species are also able to biosynthesize mycotoxins harmful to both humans and animals [2,3]. F. culmorum (W. G. Smith) Sacc. and F. graminearum Schwabe are generally considered the two most important FHB causal...
Mycotoxins represent a risk to the feed supply chain with an impact on animal health, feed industry, economy, and international trade. A high percentage of feed samples have been reported to be contaminated with more than one mycotoxin. Multi-mycotoxin contamination is a topic of great concern, as co-contaminated samples might still exert adverse effects on animals due to additive/synergistic interactions of the mycotoxins. Since mycotoxin contamination cannot be completely prevented pre-or...

1. Introduction Rapeseed (Brassica napus L.) is one of the most important species among protein-oil crops grown in regions of moderate climates. The development of improved rapeseed varieties, i.e., free from harmful erucic acid and with a reduced glucosinolate content (the so-called double zero varieties “00”), has increased interest in this crop over the past decades. As a result, a significant increment in rapeseed cultivation has been observed and consequently,...
1. Introduction Pathogenic microorganisms present in the environment are a menace for crops. At a worldwide level, diseases caused by plant pathogenic fungi significantly contribute to overall losses in terms of crop yield. To face this challenge, the use of traditional pesticides entails disadvantages related to handling hazards, cost, residues, and threats to human health and the environment. Consequently, European Directive 2009/128/EC established a framework to achieve their...
1. Introduction Soybean (Glycine max L.) is an economically valuable crop due to its high protein and oil content and wide variety of uses in food, agricultural pharmaceutical and industrial applications [1]. The United States produces 32.5% of the world’s soybeans (120 million tons/year valued at $31.2 billion), making it the second most valuable US crop [2]. In the southern US, high temperatures and dry conditions, along with poor management, can lead to...
1. Introduction Egypt started sugarcane (Saccharum officinarum L.) cultivation in 1848 when the first variety of the crop was imported from Jamaica. Since that time, sugarcane is cultivated for three main purposes: human consumption (chewing), sugarcane honey manufacturing in villages for local use, and sugar production. In the years 1922-23, the production of sugar severely dropped due to an extreme attack of the grey sugarcane mealybug Pseudococcus sacchari Ckll. Two main...
1. Introduction Toxigenic fungi and mycotoxin occurrence varies between crops, as fungal species and strains differ in their ability to infect a particular plant host. Crop varieties also show different levels of susceptibility or resistance to toxigenic fungal infection. In addition, the same plant host can be attacked by different toxigenic fungi resulting in multi-mycotoxin contamination. Additionally, interacting climate-related abiotic conditions, especially water...
Introduction The toxigenic fungi cause heavy losses in the in the yield, but the toxic poisoning of the grain is economically far more important. They provide food safety risk in human food supply and the same is true also for the animal husbandry. The amount of the global grain mass contaminated by mycotoxins is estimated to about 210 million t. A significant part of the storage loss, estimated about 420 million t is due to storage fungi [1]. As many toxigenic species occur,...
Introduction Mycotoxins are naturally-produced hazards that result from molds that can grow on cereal grains and other commodities, such as peanuts, cottonseed, and soybeans. The primary species causing mycotoxins are aspergillus (aflatoxin and ochratoxin) and fusarium (fumonisins and zearalenone) molds. Very small quantities of mycotoxins may cause illness in swine or impact production efficiency. Ideally, exclusion of mycotoxins during the growing or receiving processes...
The average level of total B-trichothecenes (1534 μg/kg) was the highest detected in the past five years and according to our risk assessment presents a medium risk to sensitive animals. Levels of ZEA, BZEA, HT2 and FB1 were low and present a low risk for the animal health and performance. Considering the mycotoxin levels detected and the likelihood of multiple mycotoxins (detected in 34% of samples), there is a greater probability of observing negative...
In 2020, Life Rainbow Biotech randomly collected 407 feed samples of raw materials and feed mills in farms and analyzed them. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3) and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit (Romer Labs®). Results: 407 feed samples collected, and 80.3% were contaminated with fumonisins and 90.4% contaminated with deoxynivalenol (table 1). All the maximum concentrations of...
INTRODUCTION Mycotoxins are structurally diverse compounds produced by filamentous fungi. Contamination of foods and feeds with mycotoxins is a significant problem worldwide (Hussein and Brasel, 2001). The major Fusarium mycotoxins occurring in cereal grains, animal feeds, and forages are the trichothecenes, zearalenone (ZEN), and fumonisins. Other important Fusarium mycotoxins include moniliformin and fusaric acid (D’Mello et al., 1999). More...
1. Introduction Fusarium head blight (FHB) is one of the most destructive diseases of wheat (Triticum aestivum L.) worldwide. Research in the last decades clarifies that the most important toxin-regulating agent is disease resistance [1–4]. Therefore, most of the work belongs to the competence of plant breeding. The artificial inoculations have a larger significance as the natural conditions do not support enough selection work, and this is true also for research. It is...
1. Introduction Up to 80% of food items of plant origin worldwide are estimated to be contaminated with mycotoxins, toxic secondary metabolites of fungi, at levels above the limit of detection (LOD) [1]. Mycotoxins threaten the health and productivity of humans and domesticated animals through dietary exposure at both acute and sub-acute contamination levels in the diet [2,3]. Many countries regulate the levels of mycotoxins allowed in imported goods, and mycotoxins are becoming...
1. Introduction Mycotoxins are natural contaminants commonly found in plant-derived foodstuffs, mainly cereals and their by-products. Since these raw materials are added as ingredients in feed formulation for different animal species, including cultivated fish, the risk of mycotoxin contamination in feed for aquaculture has increased, thus introducing contaminants (i.e., mycotoxins), which were not previously identified in fish tissues [1]. Diverse studies reported mycotoxin...
Mycotoxin contamination in newly harvested grain is a very important parameter to consider. That grain is used to feed the animals for the whole year, until the next harvest. As the saying goes, “knowing the enemy is half the battle won.” In turn, if we know the level of contamination, we can think about the best use of the wheat: to which animal species it can be fed (avoiding the more sensitive species in cases of high contamination or decreasing the...
Based on the results of this survey, the 2020 wheat crop in Poland should not automatically be considered safe for inclusion in finished feed rations for all animal species. Special attention should be paid to the medium-high average concentration of DON (1102 μg/kg), which was found in 71% of the samples with maximum concentration 9800 μg/kg. Average HT-2 and T-2 toxins level according to our risk assessment table present low-medium risk to...
