“…In fact, concerning the season investigated in this research, the rainfall levels occurred in the three surveyed regions followed the same gradient as of Fusarium infections. However, in association with climatic parameters, also other factors, such as crop rotation, fungicide application and cultivated varieties [49,51] may have played a role in Fusarium incidence in wheat grains.…”

“…Thus, seasonal patterns usually show a strong influence on the incidence of the different Fusarium species and of their mycotoxins in the grains [46,47]. In addition, agronomic factors such as crop rotations, crop management systems [27,[47][48][49], deployed varieties [50] and the use of fungicides [51] may affect FHB complex composition and the presence of secondary metabolites. One or more of these factors might potentially be the reason for regional differences within the FHB complex as well as for the presence of the mycotoxins associated with wheat grains in different world cultivation areas [30,[52][53][54][55][56].…”

In this study, durum wheat kernels harvested in three climatically different Italian cultivation areas (Emilia Romagna, Umbria and Sardinia) in 2015, were analyzed with a combination of different isolation methods to determine their fungal communities, with a focus on Fusarium head blight (FHB) complex composition, and to detect fungal secondary metabolites in the grains. The genus Alternaria was the main component of durum wheat mycobiota in all investigated regions, with the Central Italian cultivation area showing the highest incidence of this fungal genus and of its secondary metabolites. Fusarium was the second most prevalent genus of the fungal community in all cultivation environments, even if regional differences in species composition were detected. In particular, Northern areas showed the highest Fusarium incidence, followed by Central and then Southern cultivation areas. Focusing on the FHB complex, a predominance of Fusarium poae, in particular in Northern and Central cultivation areas, was found. Fusarium graminearum, in the analyzed year, was mainly detected in Emilia Romagna. Because of the highest Fusarium incidence, durum wheat harvested in the Northern cultivation area showed the highest presence of Fusarium secondary metabolites. These results show that durum wheat cultivated in Northern Italy may be subject to a higher FHB infection risk and to Fusarium mycotoxins accumulation.

The genus Fusarium is a group of fungi producing several types of toxins with toxicological effect in both humans and animals. Such fungi are commonly found in soils so it can contaminate various types of crops, preferably cereals, leading to significant economic losses. Relative humidity, storage temperature and various handling in cereales increase the possibility of contamination by Fusarium toxins. Cereals naturally have secondary metabolites that may help attenuate contamination by these toxins, but it is necessary to know strategies and mechanisms that generate inactivation mycotoxins. This chapter reviews relevant information about cereal mycotoxin contamination, as well as the production of cereal secondary metabolites as a strategy to reduce the possibility of mycotoxin contamination.

“…However, regarding trichothecenes, it must be noted that fungicides should be applied with an adequate fungicide dose, since sub‐lethal dosage can result in increased mycotoxin contents in crops showing no or low fungal infection. Also, timing of fungicide use is important …”

“…Also, timing of fungicide use is important. 146,147 Besides field management and crop husbandry, weather conditions also play an important role in fungal development on crops in the field, as well as in mycotoxin production. However, weather conditions cannot be controlled by farmers, so farmers should anticipate to unfavourable weather conditions by the previously described field management and crop husbandry practices.…”

Ruminants are considered to be less sensitive towards mycotoxins than monogastric animals because rumen microbiota have mycotoxin-detoxifying capacities. Therefore the effect of mycotoxins towards ruminants has been studied to a lesser extent compared with monogastric animals. Worldwide, a high proportion of the ruminant diet consists of silages made of forage crops (i.e. all parts of the crop above the stubble are harvested). In practice, silages are often contaminated with multiple mycotoxins. Exposure to a cocktail of mycotoxins can hamper animal production and have severe health consequences. In this article the different aspects associated with mycotoxin contamination of silage are reviewed 'from seed to feed'. An overview is given on the occurrence of toxigenic fungal species and their concomitant mycotoxins in forage crops before and after ensiling. The mycotoxin load of visually non-mouldy samples and mouldy hot spots within the same silo is also compared. Subsequently, this review delves into different problem-solving strategies. A logical first step is prevention of mould growth and mycotoxin production in the field, during harvest and during ensiling. If prevention should fail, several remediation strategies are available. These are listed, mainly focusing on the possibilities of microbial degradation of mycotoxins in vivo in silage. © 2015 Society of Chemical Industry.
