Bees provide a host of ecosystem services; most importantly they are key pollinators of agricultural crops and wild plants. In addition to this honey bees also provide products such as honey, wax, pollen, propolis, royal jelly and venom.
Since the release of the European Food Safety Agency (EFSA) Guidance Document of 2013 (revised 2014) on the risk assessment of plant protection products (PPPs) on bees, which sees the introduction of far more complex safety data requirements including a tiered risk assessment scheme. This includes different exposure routes needing to be considered, evaluation of impacts on the ecosystem, exposure assessment for each regulatory territory as well as the introduction of bumble bees (Bombus spp.) and solitary bees alongside honeybees (Apis mellifera). These new safety data safety requirements are far more complex than previous and they do introduce a potential higher failure rate.
With these new protection goals you now need to consider the survival and development of colonies and effects on larvae and bee behaviour, abundance of biomass and then the subsequent impacts on reproduction, as well as viability of colonies, pollination services and the overall yield of hive products. In addition to this, you must also consider upward, downward exposure routes, in and outside the field and the water guttation across honeybees, bumble bees and solitary bees, making these studies far more challenging than they have ever been.
Commission Regulations (EU) No 283 /2013 and 284/2013 include a requirement for data on chronic adult bee and brood toxicity, if bees are likely to be exposed during use. These data requirements are applicable for the renewal of the approval of active substances under Regulation (EU) No 844/2012 and for the approval of active substances under Regulation (EC) No 1107/2009. Therefore, receiving authorities will expect to see these data.
Are you ready for the new MRLs for honey?
Honey can potentially contain residues of PPPs and residues can sometimes be detected in honey during residue monitoring. It is therefore appropriate to establish safe Maximum Residue Limits (MRLs) for consumers. The MRLs for honey have historically been set at a default level of 0.05 mg/kg. European data requirements (Regulation (EU) No 283/2013, Annex 6.10) require studies on residues in pollen and bee products for human consumption, new technical guidelines (SANTE/11956/2016 rev.9) for determining the magnitude of pesticide residue in honey and setting maximum residue levels in honey is being implemented in January 2020.

Emma Wright
Emma is a GLP study director focusing mainly on OECD laboratory tests including acute contact and oral tests for both honey bees and bumblebees, chronic 10-day feeding tests for honeybees and single and repeat dose tests for honeybee larvae. She has also worked on field and semi-field studies and bespoke tests such as using choice chambers to determine the attractiveness of pesticide treated baits.

Steve is the Head of the Ecotoxicology group at Fera. Steve has over 22 years practical experience of conducting ecotoxicology studies in both industry and contract research laboratories. In addition, he has also spent over 15 years working as an environmental risk assessor preparing ecotoxicology risk assessments for plant protection products, biocides and REACH related registrations.
Selwyn Wilkins
Selwyn is our senior bee ecotoxicologist and has experience within apiculture spanning almost 30 years. He initially focused on honeybee disease recognition and control when he worked in the National Bee Unit. He now concentrates on bee ecotoxicology. He has over 20 years experience asa GLP study director having run numerous laboratory studies through to the higher tier semi-field and field studies. He is also a very active member within the International Commission for Plant Pollinator Relationships (ICPPR). He has also represented the UK on OECD expert panels.

MRL Decision Tree
Historically, the MRLs for PPPs in honey has been set by default to a level of 0.05mg/kg, as the methodology on the data required was not established. In 2018 the European Commission decided that Technical Guidelines for determining the magnitude of pesticide residues in honey and the setting of Maximum Residue Levels were required. As a result Technical Guidelines were developed and have been introduced by the EFSA.
MRL Factsheet
MRL builds-in a safety margin 100x that of the actual safety level for a pesticide residue. Food products that exceed a MRL are not allowed on the market. The best known primary products of beekeeping are honey and wax, but pollen, propolis, royal jelly, venom, queens, bees and their larvae are also marketable primary bee products.

Original thinking…applied to serve the agro-chem and veterinary medicines industries
Beekeepers
As part of our role we provide support and advice to government running a wide variety of studies which investigate the effects of agro chemical (plant protection products) and new veterinary medicines (for beekeepers), nutrition and disease.
Chemical Producers
Chemical companies developing plant protection products for growers need to ensure their pesticides provide effective protection against pests and diseases, at the same time as safeguarding essential pollinators, such as bees.
Food Retailers & Manufacturers
Responsible food retailers and manufacturers are committed to supporting sustainability throughout the food supply chain. This includes protecting pollinating insects as well as consumers from potentially harmful crop treatment products, such as neonicotinoids.
General Public
There are over 250 species of bee in the UK, made up of 225 species of solitary bees, 25 bumble bees, and just one honey bee. Different species have different life cycles and are active at varying times throughout the year.
Government, Research & Universities
With a wide range of expertise in the diagnosis of honey bee pests and diseases and our work in preserving the future of our pollinators, Fera are the perfect partner for your diagnostic and research requirements.
Growers & Agronomists
Pollinators are able to increase the yield and the quality of insect dependant crops. This means by embracing pollinators it can lead to higher production levels of your crops.
