From Blue Sky to Field: Regulatory Drivers for the Development of
New Methodology
Dr David N Mortimer Policy lead, environmental contaminants Food Standards Agency
Food Standards Agency • Non-ministerial Government Department responsible for food safety
and hygiene across the UK (excl Scotland from 1 April) • Independent of direct Government control • Run by a Board and Chief Executive • Set up by Labour following BSE crisis
Food Standards Act 1999
Article 6. Development of food policy and provision of advice, etc. to public authorities. Article 7. Provision of advice, information and assistance to other persons (i.e. anyone who asks). Article 8. Acquisition and review of information. (1) … obtain, compile and review information … (2a) … monitor developments in science, technology etc … (2b) … carry out, co-ordinate, commission research … (3) … ensure sufficient information for informed decisions …
Food Standards Agency
• Follows 5-year strategies 2015 – 2020 draft
We will put the consumer first in everything we do. • Consumers have the right to be protected.
• Consumers have the right to make choices knowing the facts
• Consumers have the right to the best food future* we can deliver * Impacts of: shortages; climate change; population movement; industrial development; novel foods and processes; other emerging risks.

Targeted investigations (determinand)
Outcomes (Policy)
Environmental contaminants • Dioxins & furans (chlorinated, brominated, mixed) • Halogenated biphenyls • Polycyclic aromatic hydrocarbons • Brominated flame retardants • Other FR classes (chlorinated, organophosphates) • Perfluorinated compounds • Other Stockholm POPs / candidates • Legacy pesticides • Other dioxin-like compounds • Nanoparticles • Microplastics • Endocrine disruptors
Environmental Contaminants Programme Drivers
Information sources: Symposia / networking; literature RASFF / Intelligence hub Regulatory changes
‘Baseline’ Science & Evidence projects: Total Diet Studies Marine survey
Emerging risks: New Stockholm compounds Dechloranes OPFRs Nanoparticles Microplastics Endocrine disruptors
Pathways: Waste uptakes BFRs in kitchens FRs in production plants FRs in transport
Targeted investigations (food): Infant foods & formulae Bovine meat & liver Free range/organic eggs Duck eggs
Targeted investigations (determinand): Novel & existing BFRs Dioxin-like compounds
Outcomes: Consumer protection/advice Food chain protection EU position / negotiation Data sharing (EFSA) Scientific dissemination Further research
Analytical needs
Emerging risks Screening methods (presence in food?) Validated methods for new determinands Methods for new matrices
Pathways: Dependent on type of investigation New matrices ‘In-line’methods
Targeted investigations (food) Robust, accredited* Lower cost Rapid turnaround** *especially for enforcement ** especially for incidents
Targeted investigations (determinand) Screening methods (including bioassays) Very high sensitivity Fractionations Identification of ‘unknowns’
Emerging risks • New / candidate Stockholm compounds (current)
– Pentachlorobenzene (listed 2009) – Hexachlorobutadiene (candidate) – Pentachlorophenol (candidate – dioxin source) – Polychlorinated naphthalenes (candidate – already studied) – Short chain chlorinated paraffins (complex analysis)
Future • Organophosphorus flame retardants • Dechloranes • Nanomaterials • Microplastics
Dechlorane 604
Targeted investigations Dioxin-like compounds • Advice from COT to look at dioxin-like activity • Use of bioassay(s) to determine total dioxin-like activity (Ah-receptor
binding potency) • Measure known Cl/Br/Mixed dioxins & BPs; PCNs • Select samples with ‘gaps’ • Fractionate and isolate unaccounted dioxin-like activity • Attempted ID of dioxin-like components
BFRs • Measurement of total bromine (400 samples) • Analysis for known BFRs (200 highest across all food/feed groups) • Mass balance & ID of novel BFRs • Data available for EFSA
