MRLs in honey (SANTE/11956/2016 rev. 9):

tier3 solutions GmbH expanding honeybee services to Food and Dietary Safety



Honey has been considered as a food of animal origin (Annex I of Regulation 396/2005)and therefore, determination of the magnitude of pesticide residues and subsequent setting of maximum residues level (MRLs) in honey has to be considered in EU risk assessments.



Responding to the high demand for these MRL trials following the technical guideline published 14 Sep 2018, tier3 solutions GmbH has expanded its honeybee services. We offer semi-field studies for determining maximum residue levels (MRLs) in honey according to SANTE/11956/2016 rev. 9 in the central and the southern regulatory zone.



Our portfolio of testing and expertise is constantly growing. If you are interested in residue studies of other bee products or bee relevant matrices, contact us to discuss your requirements. We will find your solution.





tier3 solutions Workshop

"From the field to the risk assessment"



On 18th September the tier3 solutions workshop „from the field to the risk assessment“ with more than 40 participants from European regulatory authorities, Industry and CROs took place at the tier3 premises in Leverkusen.


The entire higher tier tool box of field study types was presented, including practical demonstrations, and the adequate design and evaluation of generic studies (Focal species, PT/PD), residue trials and field effects studies was vividly discussed.

Participants exchanged opinions and experiences and looked at the way forward for refined birds and mammals risk assessments and the importance of realistic data from sound field trials.

Emphasized were also useful statistical tools and how to present complex study results in ‚digestible‘ reports ‘ready to use’ in the regulatory process.


We thank all participants for a very interesting and productive day!
