MYCORED aimed at developing strategic solutions to reduce contamination by mycotoxins of major concern in economically important food and feed chains, through Mycotoxins research joint actions.
The project was significantly build on the outcome of several European projects (through most coordinators/partners of FP5 and FP6) on mycotoxins by supporting, stimulating and facilitating education and cooperation with countries having major mycotoxin concerns related to international trade and human health. The direct involvement of ICPC countries (Argentina, Egypt, Russia, South Africa) and international organizations (CIMMYT, IITA) together with strong scientific alliances with International Experts strengthen the project through sharing experiences and resources from several past/ongoing mycotoxin projects in a global context.
MycoRed developed novel solution driven methodologies, handling procedures and practically useful tools to reduce significantly both pre- and post-harvest toxin contamination of selected and economically important commodities in food and feed chains.
MycoRed applied integration of specific technologies
to a set of food/feed chain targets with respect to wheat, maize, grape, nuts and dried fruits, by new advanced integrated approach based on multidisciplinar know-how and technology.
A significant reduction of mycotoxins in pre-harvest
was obtained by optimization of plant resistance, fungicide use, biocontrol, modelling and developing a decisional support system (DSS). Wheat genotypes and maize hybrids were identified to be resistant to Fusarium Head Blight and Fusarium Ear Roat respectively.
A significant reduction in DON contamination
(80-90%) was reached by using fungicide optimization technology and additional 50% reduction compared to the best technology found was reached by developing a better nozzle composition.
also on large scale in Nigeria, Argentina, The Netherlands and Italy, were done with selected biological control agents in maize, peanuts and wheat; so far up to 80% aflatoxin control reduction in maize and in peanuts
was achieved with non-toxigenic strains while F. graminearum inoculum was decreased about 70% in wheat stubble
by using antagonists.
for DON/ZEA contamination in wheat, , FUM and AFLA in maize, OTA in grapes, were developed and validated supporting DSS.
In post-harvest and processing
, relationships between environmental factors and dry matter loss relevant to EU legislative limits (DON, FUM and AFLA) were identified in wheat, maize and hazelnuts.
Novel solution driven methodologies and handling procedures based on gases O3
in wheat and maize, reduced the fungal growth and FUM production (100%) in maize.
In addition, novel anti-fungal natural compounds were identified and economically evaluated to be potentially used for post-harvest control of DON, FUM and AFLA.
An intelligent system
based on wireless sensor network devices was developed to monitoring temperature, humidity and CO2 into grain silos. Some agricultural by-products can find technological applications as low cost feed/food additives for mycotoxin reduction mycotoxins (up to 95% AFB1, 83% ZEA, 83% OTA and 47% FB1), and represent a potentially valuable source of phenolic antioxidants and undegradable fibre, which could promote health also through their ability to “trap” in the digestive tract. . Dried fruits processing by sulphuration, dehulling/peeling, sorting and roasting reduced AFLA B1 in apricot seeds (up to 99.5%), in pistachio (83%), and almonds (50%).
Advanced molecular technologies
were developed for identification of toxigenic fungi from several host plants, and novel approaches to control mycotoxigenic fungi by application of light at different wave length, permitting a better control of fungal growth and toxin production/reduction.
Advanced analytical methods
were developed and validated for multi-mycotoxin analysis in a range of food matrices from the chosen food chains and for simultaneous determination of multi-biomarkers for main mycotoxins in human and animal urine. Rapid test kits
(strip tests) for the detection of DON, AFLAs and FUMs were throughly validated and checked for cross-reactivity against conjugated and other altered forms of mycotoxins.
The project had a significant impact in the scientific international community
as well as in the stakeholders, policy makers and industry. In addition the project improved awareness and advanced knowledge on mycotoxins concerns in the world, by dissemination and training with unexpected interest expressed by different communities. International events, in cooperation with ISM and/or other organizations, were organized in the world (Austria 2009, Malaysia 2010, Africa 2011, Argentina 2011, Canada 2012, Italy 2013) with participation of about 2000 experts. Workshops on specific topics (Hungary, 2010, Turkey 2010, Russia 2011, Egypt 2011, The Netherlands 2012); 4 training courses on Detection techniques, on line too (Italy, Malaysia, Indonesia). More than 150 Young researchers/students were involved in this learning process, participating at Short Term Visits mostly from ICPC countries (24) in EU/Africa labs and Home Education sessions in China/Argentina/Indonesia/USA. Twinnings (EU-Canada; EU-Argentina) and scientific networks were activated by signing 20 alliances/agreements worldwide.

Progresses at 18 months
In wheat 40 cvs were compared with three different inoculation methods in two location against four isolates of Fusarium. Visual symptoms, kernel infection and DON contamination was measured. Two populations were searched for QTLs in Szeged, the Hobbit sib series in JIC. For gene expression against F. verticillioides in maize three experiments were made with gene expression test by microarray methodology. In wheat farm scal and small plot fungicide tests were made with new nozzle combination on three cvs and eight fungicides. Here also the translocations of fungicide active ingredients were followed. In maize again 40 hybrids were tested in 2010 (60 ib 2009 as preliminary trial) by two inoculation methods. The field work was finished in November this year.
Selected antagonists were tested in field experiments in wheat and maize in The Netherlands, Italy and Argentina to reduce mycotoxins produced by Fusarium
spp.. Various experiments were carried out in peanuts and maize aiming at the reduction of aflatoxin produced by Aspergillus
spp. Economics of large scale production of selected antagonist has been preliminarily assessed.
All available data were collected to chose/develop predictive models for mycotoxin contamination in wheat, maize and grapes. A sampling protocol was developed for all the crops sampling points were defined in all countries involved; relevant mycotoxins were quantified in all the wheat samples at harvest. A questionnaire was prepared suitable to collect all data regarding geographic coordinates and cropping system of the selected crops and filled for each sample. A meteorological station reasonably close was selected for each sampling point and meteorological data were collected. All data were stored in a data base and they were/will be used for model validation.
Four aspects of the post-harvest strategies were developed during this period.
The effect of environmental factors on respiration of wheat maize, and hazelnuts inoculated with key mycotoxigenic fungi were done. Data was used to develop models to relate environmental factors to dry matter loss (DML) and to mycotoxin contamination. O3
has been tested in vitro for efficacy against A.flavus
. A large number of novel compounds have been screened for efficacy against F.graminearum
and control of mycotoxins. The best ones have now been chosen for in situ storage experiments. A sensor “ball” system which incorporates temperature, relative humidity and CO2
has been developed, and the associated hardware completed.
Agricultural by products and commercial products have been tested in vitro for the ability to bind simultaneously aflatoxins B1
, ZEA, FB1
, OTA and DON. Pilot experiments were performed to determine in vivo parameters that should be use to determine the toxicity of mycotoxin and the subsequent effect of agricultural and commercial products. The ability of yeast strains to detoxify aflatoxins B1
and OTA has been initiated. The efficacy and safety of food processing procedures in reducing mycotoxin content has been initiated. We observed that sulphuration dehulling/peeling and sorting significantly reduced the content of aflatoxins B1
of apricot seed reduced aflatoxins B1
. Pilot, in vitro tests were performed to asses the cellular toxicity of FB1
The strain collection kept at CNR has been extensively increased with respect to toxigenic Fusaria, Aspergilli and Penicillia. For important species of that collection specific primers and new detection methods have been established. Molecular characterization of Aspergillus species section Nigri isolated from grapes have been performed. The influence of external stress factors on aflatoxin producing Aspergilli and on ochratoxin producing Penicillia have been analysed. Especially the influence of light of different wave length on growth of several food borne fungi and especially on ochratoxin A biosynthesis has been carried out.
The following analytical tools have been developed and/or validated: 1) LC-MS/MS or LC-HRMS based methods for a) multi-mycotoxin analysis in food matrices; b) fungal metabolite profiling in cultures; c) masked DON- and ZON species in food d) detection of mycotoxin biomarkers in urine and e) determination of novel biomarkers as well as 2) strip tests for rapid test systems.
MycoRed different dissemination actions have been taken to introduce the project in the international scenario opening the road to further events, by presentations of project worldwide at international conferences and workshop, project’s website and promotional materials. International conferences, workshops and training activities, including Short Term Visits have been organized as well as networking actions at different levels.
