Climate change has been reported as a driver for emerging food and feed safety issues worldwide its expected impact on the presence of mycotoxins in is great concern. Aflatoxins have highest acute chronic toxicity all mycotoxins; hence, maximal concentration agricultural products their commodities regulated worldwide. The possible patterns aflatoxin occurrence crops due to climate matter concern that may require anticipatory actions. aim this study was predict contamination maize wheat...
During the last decade, there have been many advances in research and technology that greatly contributed to expanded capabilities knowledge detection measurement, characterization, biosynthesis, management of mycotoxins maize. MycoKey, an EU‐funded Horizon 2020 project, was established advance transfer around globe address mycotoxin impacts key food feed chains. MycoKey included several working groups comprising international experts different fields mycotoxicology. The Maize Working Group...
The occurrence of the most widespread type A and B trichothecenes zearalenone was surveyed in soft durum wheat produced northern Italy. total 293 fields, grown years 2009-2011, were surveyed; for each field, weather cropping system data collected. results indicated a high deoxynivalenol incidence, with always more contaminated than wheat; 2010, percentage samples exceeding European Commission legal limit 39.6%. As regards trichothecenes, contamination observed 2010. In wheat, an incidence...
Twelve yeast strains isolated from the surface of Italian typical dry-cured hams, belonging to D. hansenii, maramus, C. famata, zeylanoides and H. burtonii species, previously selected for their ability grow in ham-like substrates, were screened antagonistic activity against a toxigenic strain P. nordicum inhibition ochratoxin A (OTA) biosynthesis. On average, inhibitory was lowered by increasing fungal inoculum enhanced NaCl presence. In assay conditions, most effective, both inhibiting...
The aim of this study was to investigate in vitro and model the effect temperature (T) water activity (aw) conditions on growth toxin production by some toxigenic fungi signaled cheese. Aspergillus versicolor, Penicillium camemberti, P. citrinum, crustosum, nalgiovense, nordicum, roqueforti, verrucosum were considered they grown under different T (0–40 °C) aw (0.78–0.99) regimes. highest relative occurred around 25 °C; all very susceptible 0.99 optimal for almost species (except A. awopt =...
The occurrence of mycotoxins differs greatly from year to and this variation has been attributed climate variability. aim study was consider the variability fungal infection mycotoxin contamination on a small geographic scale as possible result local weather conditions. presence Fusarium spp. Aspergillus their related investigated in 51 maize fields grown 2014 Emilia Romagna region, northern Italy; information regarding cropping system collected for all fields. Samples at harvest were...
Meteorological conditions are the main driving variables for mycotoxin-producing fungi and resulting contamination in maize grain, but cropping system used can mitigate this weather impact considerably. Several researchers have investigated operations' role mycotoxin contamination, these findings were inconclusive, precluding their use predictive modeling. In study a machine learning (ML) approach was considered, which included weather-based mechanistic model predictions AFLA-maize FER-maize...
Anthropogenic climate change is altering the distribution of mycotoxigenic fungi, including Aspergillus flavus and Fusarium spp., which produce harmful mycotoxins like aflatoxins fumonisins that can contaminate food feed supplies. These shifts impact agriculture, security, safety, as fungal life cycles depend on temperature, humidity, rainfall. Using high-resolution ERA5-Land data (1950–2021), we have calculated a daily Aflatoxin Risk Index (ARI) to identify high-risk regions...
Malawi is one of the poorest countries in world, with high levels malnutrition and little domestic mycotoxin regulation. Domestically grown maize largest single source calories country a large contributor to economy. This research uses Regional Climate Models (RCMs) determine climatic conditions three regions (Northern, Central Southern) 2035 (2020–2049) 2055 (2040–2069) as compared baseline climate 1971–2000. data then used inputs Food Agriculture Organization's (FAO) AquaCrop model assess...
The influence of climate change on agricultural systems has been generally accepted as having a considerable impact food security and safety. It is believed that the occurrence mycotoxins will be greatly affected by future scenarios this confirmed recent data. Temperature (T) CO2 increases, variation in rain intensity distribution, well extreme weather events, affect dominant fungal species different ways, depending their ecological needs. Therefore, aim work was to study Aspergillus flavus...
The occurrence of mycotoxins associated with Fusarium spp. and Aspergillus flavus in Northern Italy, the role cropping systems, were investigated on 140 field samples collected over years 2009–2011. Samples analysed for fumonisins B 1 2 (FBs), aflatoxins , G (AFs), deoxynivalenol (DON) zearalenone (ZEN) using validated analytical methods. Information on: maize hybrid, preceding crop, tillage applied, mineral nutrition, pest disease control, severity European Corn Borer (ECB) attack, sowing...
In recent years, very many incidences of contamination with aflatoxin B1 (AFB1) in pistachio nuts have been reported as a major global problem for the crop. Europe, legislation is force and 12 μg/kg AFB1 maximum limit set pistachios to be subjected physical treatment before human consumption. The goal current study was develop mechanistic, weather-driven model predict Aspergillus flavus growth on daily basis from nut setting until harvest. planned steps were to: (i) build phenology stages,...
The aim of this work was to design the potential support given by predictive models maize management in a chain vision aimed at minimising aflatoxin contamination and human animal exposure. There are some available but only AFLA-maize, which is mechanistic model, suitable for risk prediction worldwide. Weather data mandatory input output depends strictly on sources, thus being influenced both time distance scale meteorological data. A user friendly summary interface from represented maps...
Mycotoxin represents a significant concern for the safety of food and feed products, wheat one most susceptible crops. To manage this issue, fast, reliable, low-cost test methods are needed regulated mycotoxins. This study aimed to assess potential use electronic nose early identification samples contaminated with deoxynivalenol (DON) above fixed threshold. A total 214 were collected from commercial fields in northern Italy during periods 2014−2015 2017−2018 analyzed DON contamination...
Ochratoxin A (OTA) is a fungal metabolite dangerous for human and animal health due to its nephrotoxic, immunotoxic, mutagenic, teratogenic carcinogenic effects, classified by the International Agency Research on Cancer in group 2B, possible carcinogen. This toxin has been stated as wine contaminant since 1996. The aim of this study was develop conceptual model dynamic simulation A. carbonarius life cycle grapes along growing season, including OTA production berries. Functions describing...
Apples and apple-derived products can be contaminated with patulin and, to a lesser extent, aflatoxin B1 fumonisins. Fruits were collected from Golden Delicious Imperatore trees in three orchards Veneto, Northern Italy, analysed for the presence of fungi mycotoxins. Sampling analyses also carried out storage bins final puree tanks along apple-puree production chain. Alternaria spp. Penicillium commonly isolated apples field, but their varied cultivar orchard location. In contrast,...
No information is available in the literature about influence of temperature (T) on Penicillium and Aspergillus spp. growth mycotoxin production cheese rinds.
