“…Several of the pesticides detected in this study such as benzovindiflupyr, bixafen, fluopyram, fluxapyroxad, metrafenone, piperonyl butoxide, pirimiphos-methyl, pyraclostrobin, tebuconazole and trifloxystrobin were also detected recently in samples of brewery's spent grains intended for feeding of dairy cows in Austria (Penagos-Tabares et al, 2022c). It is known that barley (cereal mostly used for beer production) is a crop frequently contaminated with traces of fungicides (Palladino et al, 2021). Given the incorporation of commercial concentrate feeds and other feedstuffs non-produced at the farm, the pesticides detected in this study can also be different from the ones reported by the farmers on the crop feeds (cereals, like maize, wheat, rye and others).…”

“…Six studies have data from 2018, five of them in grains and one of them in milk. The first publication found 67% of NIV in n = 154 barley (Garmendia et al, 2018), and the second found DON (90%) and ZEN (9%) also in barley (n = 89) (Palladino et al, 2021).…”

Mycotoxins are natural metabolites produced by species of filamentous fungi belonging mainly to the genera Aspergillus, Fusarium, Penicillium, and Alternaria, which can grow in various crops and foodstuffs. The South American climate is diverse, varying from tropical, temperate, and arid to cold, ideal for the growth of different types of fungi and mycotoxin production. This mini review aimed to describe the natural occurrence of mycotoxin in food in South America from 2018 to 2023, identifying research gaps and challenges in an era of climate change. We analyzed 53 studies, 21 from Brazil. Most of the mycotoxins analyzed in South America were the traditional and regulated mycotoxins, with variable occurrences depending on the region, climatic conditions, and methodology used. Emerging and modified mycotoxins have only been studied in Argentina and Brazil, where some studies have shown high occurrences. Given this, it is essential to strengthen food safety laboratories and surveillance capabilities and establish early warning systems. It is also essential to continue working to raise awareness of mycotoxins as a public health issue and to study and prevent the impact of climate change on soil microbial population, the new prevalence of fungi, and the profile of toxigenic species. An effective connection and collaboration between disciplines and sectors in different countries is needed to meet this research challenge.

“…Tebuconazole preparations increased the gushing and higher content of oxalates, pentosans and ß-glucans was recorded versus the control. LC-MS/MS system was employed to examine 89 barley grain samples (Palladino et al, 2021). Residua of fungicidal active ingredients in concentrations under Regulation (EC) No 396/2005 limits were determined in 66 samples, mostly azoxystrobin, carbendazim, chlorothalonil, epoxiconazole, and fluxapyroxad.…”

The routine and prophylactic use of fungicides in cereals leads to increased aggressiveness of Fusarium infections. Cross-resistance to triazole compounds represents a significant health risk to both plants and humans. The application of some widely used fungicides causes increased production of DON. Residual concentrations of hydrophobic triazoles change chemical profile of malt and cause delayed fermentation with an impact on alcohol content. Increasing legislative restrictions of pesticide applications encourage the search for alternatives, starting with the overview of current state of knowledge on biological protection against Fusarium spp. Despite the fact that bioagents have been researched intensively, including field applications and several registrations, biological preparations for disease control against Fusarium head blight (FHB) of malting barley are not used on a mass scale. Generally, bioagents appear to be quite sensitive to environmental changes and soil variability, which causes problems with the evaluation of their effectiveness under field conditions. For efficient disease control of malting barley, the application based on biopreparations registered against FHB combined with weather prediction system can be recommended. With an emphasis on the occurrence of Fusarium graminearum as a key producer of deoxynivalenol (DON), the prediction system for malting barley should be employed from plant emerging to milk stage. When predicting a high incidence of the pathogen, chemical intervention must be considered. However, repeated application of bioagents in field conditions together with the implementation of bioagents directly into the malting process proved to be a promising way to decrease chemical interventions from the cultivation of malting barley.
