During beginning of
2014, the milk
industry declared
that they are ready
to implement
European
regulations
From the
first of July
2014 the
limit for
aflatoxin M1
was
decreased to
0,05
microgram/
kilogram
Limit
decreased
• 23% of produced milk
still do not meet the
standard
• 30-40% of farmers can
not achieve the
requirement
• 10 000 families will
loose their income

Just 15 days after decrease,
the aflatoxin M1 level was
again increased, this time to
0,25 microgram/kilogram

Challenges /problems
• Lot of small producers without clustering
• It is difficult to control all the small producers by
phytosanitary and veterinary inspectors- huge
number of official controls and samples are needed,
high cost
• No precise data of remained corn quantities from
previous year-silos and private cribs
• Sampling from big storage facilities
• Need to increase storage hygiene
• Low number of inspectors
• According to food safety law every producer is
responsible for own product, but...the ministry alway
has a heavy responsibility to social component
What can be done from farm to fork?
Prevention, monitoring, control, education
- Public awarenes and farmers education
- Preventive measures during vegetation
- Hygiene rules before and during storage
• Irrigation of maize is not
realistic at this point
• Chemical control against
corn borer
• Lower plant density
• Weed control
• Optimal fertilisation
• Optimal harvest time

• Cleaning the storage
capacities
• Checking the mycotoxin
content of every seed
lot
• No mixing of seed lots
with different infection
level
• Insect control in
storages- fumigation
• Continuous control of
temperature and
moisture
Monitoring, better communication with producers
• 29 State extension services - Plant protection forecasting and reporting services
• They monitored flight and population abundance of the European corn borer, as
well as occurrence of disease symptoms on ears.
• Informations sent to producers
Field inspections

• No predicting models for aflatoxin validated in Serbia
• Predicting models for Africa?
• Not enough data for biological control in Serbia
• Field testing of resistance to aflatoxin accumulation
is time consuming because different climatic
conditions from year to year – testing in Africa?
• Differences in fungal population- in mycotoxigenic
potential
• About scientific research in Serbia
• With partners from Hungary during 2012 and 2013 University of Novi Sad
have implemented
• HUSRB/1002/1.2.2/062 Improvement of safety of corn-based feedstuffs
through using more resistant hybrids and management of corn processing
(Hungary-Serbia IPA Cross-border Co-operation Program), Reference
number of the Call for Proposals: HUSRB/1002/1.2.2/062 (2012-2013).
• We have found differences between commercial hybrids from Hungary
and Serbia in susceptibility to Aspergillus flavus and toxin accumulation.

SFS-13-2015 Biological contamination of crops and the food chain
Specific challenge: The occurrence of biological contamination in various crops is of major
concern as it has major implications for food and feed safety, food security and international trade.
Worldwide, it is estimated that mycotoxins are responsible for losses of up to 5-10% of crop
production. Integrated approaches rather than isolated solutions are required to effectively
control the incidence of mycotoxins in crops and reduce contamination throughout the feed
and food chains.
Scope: Proposals should aim at reducing the risk of mycotoxin contamination in crops and all
along the feed and food chains. They should bring about technical, management and
organisational solutions (including HACCP techniques) that are effective at the various stages of
production as well as at pre- and post-harvest levels and also deal with the safe use of
contaminated batches. Proposals should benefit conventional and organic supply chains and
fall under the concept of 'multi-actor approach' and allow for adequate involvement of the
farming sector in proposed activities. In line with the objectives of the EU strategy for international
cooperation in research and innovation and in particular with the implementation of the EU-
China dialogue, proposals are encouraged to include third country participants,
especially those established in China .

• Main goals:
• Reduction of aflatoxins in maize through
genetics (drought resistance, early maturity)
• Biocontrol for aflatoxins in maize
