“…are very common mainly in organic plant material like compost, fruits or vegetable, wood pellets and farmyard manure and are known to cause food spoilage (Domsch et al 2007 ; Hoog et al 2000 ). Mucor has been detected in air samples in Italian vineyards (Magyar et al 2009 ), in grape berries in the Tokaj wine region in Hungary (Felšöciová et al 2015 ) and is described as a pathogenic fungus on pear fruits (Mari et al 2000 ). To the best of our knowledge the current study is among the first describing Mucor from vineyard soil samples below 10 cm depth.…”

In a vineyard we examined the effects of broad-spectrum herbicides with three different active ingredients (glyphosate, glufosinate, flazasulfuron) on soil microorganisms. Mechanical weeding served as control treatment. Treatments were applied within grapevine rows and soil samples taken from there in 10–20 cm depth 77 days after application. Fungi were analyzed using classical sequencing technology and bacteria using next-generation sequencing. The number of colony-forming units (CFU) comprising bacteria, yeasts and molds was higher under flazasulfuron compared to all other treatments which had similar CFU levels. Abundance of the fungus Mucor was higher under flazasulfuron than glufosinate and mechanical weeding; Mucor was absent under glyphosate. Several other fungi taxa were exclusively found under a specific treatment. Up to 160 different bacteria species were found – some of them for the first time in vineyard soils. Total bacterial counts under herbicides were on average 260% higher than under mechanical weeding; however due to high variability this was not statistically significant. We suggest that herbicide-induced alterations of soil microorganisms could have knock-on effects on other parts of the grapevine system.

“…Also, PATand citrinin-producing species can contaminate grapes to a lesser extent. In fact, the presence of Penicillium expansum has already been reported in Portugal, Chile, Slovakia, and Hungary (Abrunhosa et al 2001, Diaz et al 2011, Felsociova et al 2015a, 2015b, Tancinova et al 2015.…”

The Route of Mycotoxins in the Grape Food Chain

et al. 2019

Grapes are consumed throughout the world in different ways, ranging from fresh fruit to processed products. Regardless of the product, risk management starts in preharvest stages to control initial development of mycotoxigenic fungi and avoid consequent problems in the whole chain. The main concern in grapes and grape products is the presence of black Aspergillus species and the subsequent production of ochratoxin A. However, other mycotoxigenic fungi have been detected and may need further attention. The adoption of crop management strategies, such as selection of varieties, training system, and soil management, can reduce fungal proliferation. Biological methods can also be used to inhibit fungal contamination. These methods can substitute for chemical approaches and be used in later phases of grape processing to allow safe storage. Due to the wide range of products that can be obtained from grapes, different fungal species can be responsible for postharvest deterioration. Taking this into account, the aim of this work is to review strategies for mitigation of mycotoxin risk in the whole grape chain considering data on the occurrence and development of mycotoxigenic fungi and mycotoxin biosynthesis.

The present work constitutes the external scientific report of the EFSA open call OC/EFSA/FEED/2015/01. The aim of the call was to provide EFSA with a database from a review on the taxonomical description and potential toxigenic capacities of microorganisms used for the industrial production of feed additives and food enzymes. The review includes microorganisms used as source of feed additives and food enzymes for which EFSA has received or can potentially receive applications for safety assessment, and which have not been recommended for Qualified Presumption of Safety status. The database also comprises the molecular taxonomical identifiers and biosynthetic pathways involved in the production of toxic compounds and the responsible genes. The main result of the project is shown as a database developed according to the EFSA data structure. The methodological aspects and the queries used in the systematic search, as well as the procedure applied for the screening of scientific documents retrieved are described in this report. Details are available in supplementary appendices.In total, 22970 scientific documents were screened in the literature search, from which 411 were initially selected for providing pertinent data for the scope of the project. From the review of the selected articles, 474 bioactive secondary metabolites were recorded and 59 compounds were further studied in order to obtain data on their toxicology and the conditions in which they are produced by the microorganisms used in industrial fermentations. The database generated in this project comprises details that characterise, when available, the production conditions, genes involved and toxicity of these 59 compounds. This provides information that can be used to establish safety measures when using potentially toxigenic microorganisms in industrial fermentations Disclaimer: The present document has been produced and adopted by the bodies identified above as author(s).
