First stage: Prevention (2)
• Acquisition conditions of swiss granum
• Examples of preventive recommendations
- at production stage
▪ before sowing: crop rotation, soil tillage,
variety selection
▪ after sowing: fertilisation (needs of plants)
▪ before harvest: crop control
▪ during harvest: information of the collecting
centre, separate harvest
▪ after harvest: hackle, allocate and incorporate straw residues
- at acceptance stage
▪ cooperation with farmers
▪ hygiene measures
▪ visual control, retention samples before unloading
▪ sorting, cleaning and storage
▪ retention samples before delivery

First stage: Prevention (3)
• Acquisition conditions of swiss granum
• List of proposed varieties: description of susceptibility

First stage: Prevention (4)
• Additional conditions / recommendations
of market partners
• Cereal production in contract farming
often with additional Label „Suisse Garantie“
• Education of the staff (collecting centre)
- sample drawing / size
- visual recognition of infested cereal
• Instructions for the proceeding
- in case of visible Fusarium on kernels
- in case of positive rapid test
• No transport of wheat to the mill without DON-Rapid test
• Evaluation of all information and verification of the concept

Second stage: Forecast (1)
• Mycotoxin forecast of swiss granum
• Basis
- decision support system Fusaprog
- observation of health state of the fields before harvest
▪ taxation of the field trials of Agroscope and swiss granum
▪ observation of the official extension services
▪ observation of the market partners
• Report of the situation before harvest
- established by the working group “food safety” of swiss granum
- published in mid-July
S. Scheuner / Prevention strategies – a cereal stakeholders’ perspective 11
Second stage: Forecast (2)
• Mycotoxin forecast of swiss granum
• Examples (before harvest)
- Extract July 6, 2018
▪ higher contamination with fusarium head blight
than 2017, dry weather conditions
▪ medium risk of contamination with DON
- Extract July 12, 2016
▪ high level of fusarium head blight
▪ high risk of contamination with DON
- Extract July 13, 2015
▪ low level of fusarium head blight (winter wheat)
▪ low risk of contamination with DON, except spring cereals
- Extract july 10, 2012
▪ high risk of contamination with mycotoxins predicted
▪ appeal to increased attention

Future challenges (1)
• Breeding / List of proposed varieties
• New varieties with better resistance
• EU varieties are less location adapted (critical DON- Values)
• Increase sensitivity of the farmers
• Increasing surface of extensive cereal production without fungicides
• Crop rotation / soil tillage
• Agricultural policy
• Action plan for plant protection products
• Votes on people's initiatives
S. Scheuner / Prevention strategies – a cereal stakeholders’ perspective 17
Future challenges (2)
• Maintain / develop decision support system Fusaprog
• Accuracy
• of the samplings
• of rapid tests
• Analysis costs
• Increasing analysis costs for swiss granum
• Prevent multiple analysis on the same lot
• Imported grain
• EU = +/- harmonized, but not the rest of the countries

Conclusions
• Quality assurance (risk management) proved of value
• Cultivation methods are the most important part of the
value chain between „seed and bread“ with the highest
potential to reduce mycotoxins
• Financial resources for the mycotoxin analysis have to be
use more efficient (no duplication)
• Continue and increase the existing collaboration between
the market partners
• In swiss granum discussions take place, solutions are
found and carried by the market partners
S. Scheuner / Prevention strategies – a cereal stakeholders’ perspective 19
Entire value chain requested
• Efforts of all partners requested to keep the today’s and
future challenges with mycotoxins under control
• This is the only way to produce
• safe food
• safe animal feed
Thank you for your attention
