Fruits and vegetables are an import part of a healthy diet, and their consumption is expected to increase
in the future because of health promotion. However, climate change and globalization will effect
their safety. In order to maintain the desired level of food safety in Europe, it is necessary to explore
new food contamination pathways and approaches to deal with these projected changes.
An imported food safety problem is the presence of emerging toxigenic fungi and their
mycotoxins on fresh fruits, vegetables and derived products.
This research is performed in the frame of veg-i- trade project (www.veg-i-trade.org).
The objective of the research is to develop a farm-to-fork risk assessment model to predict the mycotoxin concentration in
fresh and derived products in order to predict future risks due to climate change and growing import of foods from third countries.
We will focus on new emerging mycotoxins (Alternaria species, ochratoxin A and patulin).
Alternariol monomethyl ether
Collecting data of mycotoxin concentration on dried plant,
fresh and derived products in cooperation with trading countries
as Brazil, Egypt, South-Africa and India in order to make a risk
ranking, risk prioritization of mycotoxin/produce type.
Screening with a LC/MS method on tomatoes, bell peppers,
soft red fruits and onions and derived products for ochratoxin
A, Alternaria species (alternariol, alternariol monomethyl ether
and altenuene) and patulin.
Identification of the fresh supply chain. The mould growth and the mycotoxin production
will be studied as function of some important parameters (e.g. time, temperature,
Different scenarios (globalization and
climate change) will be applied to estimate
the effect on the mould growth and
Predicting the mycotoxin exposure from
fresh and derived products by developing
and risk ranking a farm-to-fork risk
All this information will be integrated in order to develop a farm-to-fork risk assessment model for the selected cases. In
this way selected mycotoxins related to specific plant products can be evaluated through different scenarios. Also a
probabilistic risk assessment will be conducted using the data of mycotoxin concentration on dried plant products and fresh
produce and their derived products. The output will be used to develop different scenarios to measure the impact on
mycotoxin exposure due to trade and import from third countries and to feed the discussion on the food sovereignty.
