Bundesverband Naturkost Naturwaren (BNN) e.V.
• BNN respresent the specialised organic market in Germany
whose turnover was about 2 billion Euro in 2013
• BNN offers various possibilities for a dialog between
member companies and promotes the open exchange of
information and views along the value chain
• BNN was founded in 1983. A lot of its members are pioneers
of the German organic market
• Active members of BÖLW (German umbrella organisation
including organic famers organisations)
History of BNN-Guideline Value
• Before 2001 there was no guidance „how to deal with pesticide
detections in organic products“ (EU Organic Regulation is process
orientated and therefore sets no organic pesticide/contaminant
limits)
• BNN general assembly established BNN-Guideline Values for
Pesticides in 2001
• Practical means to distinguish between pesticide findings resulting
from unpredictable, unavoidable circumstances and application of
non-permitted substances or technically avoidable contamination
• BNN-Guideline Value is not only a value but a concepts, therefore
the name was changed in 2011
BNN-Orientation Value for pesticides - A guideline to
evaluate pesticide residues in organic products
Single Residue
BNN-Guideline-Value for each substance is 0.010 mg/kg (expanded
measurement uncertainty: 50%).
Multiple Residues
Exceeding of a total of two pesticide agents is not allowed (levels ≥ 0.01
mg/kg, expanded uncertainty not considered)
• Exception for substances allowed in EU Organic Regulation
(834/2007; 889/2008)
BNN-Guideline Value: processed products
• In case of processed products which are diluted or
concentrated (e.g. by drying or extraction) during
processing, the residue level has to be calculated back
to the fresh product
• BUT: In case of indications of post-harvest
contaminations, contaminations related to storage
protection agents, the residue levels must not be
calculated back to the fresh product.
BNN-Guideline-Value/BNN Approach
• BNN- Guideline-Value is not a limit and therefore should
not be interpreted as an „organic MRL“, critical level etc.
• first „doubt“ according to Art. 91(2) of Reg. 889/2008, it
has to be checked whether the provisions of Organic
Agriculture are met
• Exceeding the BNN-Guideline-Value does not „prove“
conventional origin and residue-free is not the same as
organic
BNN-Approach: Individual evaluation of each case is
necessary! (cultivation, transport, storage, packaging, trade)
Public Statements
• General rule: individual evaluation
• But in the case of environmental contamination, organic
products can be affected by unavoidable levels of pesticides,
which can affect a variety of producers, processors and
traders
BNN has introduced the possibility to issue Public
Statements Concerning the Use of the BNN
Guideline Value for Pesticides (www.n-bnn.de ->
BNN-documents)
Sampling
Sampling method depends on the aim of sampling/question
Formal/representative sampling
• Compliance with legal requirements (MRLs)
• Importers
Informal sampling
• Consumer‘s perspective
• Risk orientated
• In general more suitable for check of compliance with EU organic
regulation (drift? Seperation? Conmingling?)
BNN-Monitoring of Fruit and Vegetables/shelf
stable products
• 24 participating companies
• 10th anniversary in 2013, about 5000 samples
• We understand pesticide analysis as supplemantary to
process control (tool to find mistakes or non-compliances
in the process of procustion, transport, packaging, storage
and processing)
• Last but not least: to keep cheating suppliers out of the
market
• In 2012 BNN-Monitoring of shelf stable products started/
18 companies
• BNN-Monitoring of shelf stable products works without
supplier‘s names (at the moment).

•
Risk orientated choice of products and analitical
methods/substances: we try to find pesticides and have a special
focus on substances that are not covered by „multimethods“
•
Co-ordinated sampling: co-ordinated sampling in order to avoid
double checks of the same suppliers and to try aned cover all
suppliers
•
Laboratory approval: participating comapanies have to work with
BNN-approved labs.
•
Common database for transparency: all participants have always
access to all results including supplier‘s names and lab reports

„successful“ (BNN definition) participation in ringtest
assessment of laboratories‘ competencies in terms of
interpretation of results
• the participation in BNN organised laboratory test is obligatory
(undercover test samples) related to each module combination the
laboratory is approved for (f. ex. pesticides in fruits and vegetables).
• After a 3 years-period re-evaluation taking into consideration the
analytical performance of the last 3 years including the development
of the laboratory
Stable isotope analysis (N)
• In 2010 we complemented pestice analysis with stable isotope
analysis in order to check the nitrogen fertilization
• The analysis of stable nitrogen analysis can give evidence of
the use of mineral fertilisers (ratio 15N/14N [‰] v.s. Air), but
in most cases the results are not 100% sure and have to be
checked.
• Useful additional tool accompanying pesticide analysis, since
the non-use of mineral fertilisers is the second important is
the second important principal apart from the non-use of
pesticides.
Results: several (very) suspicous samples, research a lot of work,
especially because we had to explain to everybody involved what
stable isotopes are etc.
