Overview Safety Risks

  • Collab4Safety

    • Aims of WP1: Global mapping of food safety

  • The importance of ensuring global food safety

  • Conclusions of the ‘Go-Global’ project

  • The Delphi technique

  • Application of Delphi to Collab4Safety

Emerging themes in food security
Emerging Themes in Food Security Safety Risks

Food Security has been defined as the situation:

“when all people, at all-time have physical and economic access to sufficient and safe nutritious food to meet their dietary needs and food preferences for an active healthy life” (FAO,1996).

Collab4Safety Safety Risks

  • WP1 Aims: to map international research, innovation and training activities and policies in the area of food safety, and to identify gaps in knowledge salient to policy development:

    • Duplication of effort and lack of harmonisation regarding existing research practices,

    • Gaps in international research and training needs, (including capacity building and infrastructure requirements),

    • Critical success factors and identification of barriers to effective policy translation

    • Identification of emerging issues which have regulatory and legal implications, and the consequences

Collab4safety wp1 methods
Collab4Safety: WP1 Methods Safety Risks

  • Delphi methodology

    • used to ensure the involvement of global experts

  • Builds on work conducted in the Go-Global project

    • that focused on developing a research agenda for food safety risks.

  • Stage 1 = Scoping workshop issues to be explored in the Delphi including:

    • Issues driving the control and mitigation of emerging food risks

    • Knowledge gaps with respects to existing and emerging risks and developing policy frameworks

Defining existing and emerging risk
Defining Existing and Emerging Risk Safety Risks

  • Emerging food safety risk can be defined as:

    ‘unanticipated risks that occur accidently or naturally as well as those arising from deliberate fraud or acts of malevolence…Emerging food risks are not necessarily new risks, some have always represented a threat, but only recently been identified’ (Wentholtet al, 2010, p.1732)

Getting food safety mitigation wrong has profound consequences
Getting Food Safety Mitigation Wrong has Profound Consequences…

  • Economic costs

  • E coli outbreak killing 16 people (May 2011)

  • German authorities blame Spanish Cucumbers

  • Germany later admits that Spanish cucumbers are notto blame

    ‘Source of outbreak… remains a mystery as row spreads across Europe and Spain counts the cost of ban on its vegetables’ (The Guardian, 31st May 2011)

Consumer trust
Consumer Trust Consequences…

  • Emotional consumer responses

  • Meat from a cloned cow enters the UK food Chain (FSA, 2010)

  • 2 bulls from the embryo of a cow cloned in the USA is bought by a farmer in Nairn in the highlands, and meat from one is sold to consumers.

Steve Innes, Newmeadow farmer, says: "We acted in good faith”.

(BBC News, 4th August 2010)

Horsegate not a food safety risk
Consequences…Horsegate’- Not a food Safety Risk?

  • Horse and Pig DNA detected in products sold as ‘beef’ (January, 2013)

Horsegate t he issues
Consequences…Horsegate’- The Issues

  • Fraud and Standards

  • Beef supply chain (post BSE) expected to be tightly controlled

  • Public concern:

    • Criminal activity

    • Illegal economic gain

    • Not focused on food safety (the issue of Bute?)

Environmental consequences
Environmental Consequences Consequences…

  • Dioxins are persistent environmental contaminants

  • Dioxins accumulate in the food chain (90% of human exposure through food)

  • Recent dioxin related food safety issues include:

    • Belgium poultry feed supply chain caused by illegally disposed industrial oil (1999)

    • Ireland pig feed supply chain (2008)

Go global conclusions
Go-Global Conclusions Consequences…

  • Political will to engage in emerging food risk identification and management

    • may be problematic

  • Need to keep the issue on international and national research agendas

    • Achieved through effective stakeholder engagement

  • The effective sharing of data pertinent to emerging food risks across expert communities needs to be supported

    • Perhaps through intervention of intergovernmental organisations and …

  • Joined up global policy

Existing and emerging threats to food safety
Existing and Emerging Threats To Food Safety Consequences…

  • Food chain contamination:

    • Microbial contamination (e.g. salmonella, E coli)

    • Veterinary drug residues (Bute?)

    • Antibiotic resistance?

    • Heavy metals and chemicals

      • Methyl mercury in fish

      • Sudan dyes

    • Unintended presence of nanoparticles

    • Unintended presence of GMOs

    • Unintended inclusion of toxic ingredients (e.g. Japanese Star Anise)

Existing and emerging threats to food safety 2
Existing and Emerging Threats To Food Safety (2) Consequences…

  • Food chain contamination:

    • Dioxins

    • Secondary metabolites

      • Mycotoxins

      • Infectious animal diseases

Go global global threats to food safety
Go-Global: Global Threats to Food Safety Consequences…

  • Most frequently identified global threats:

    • Microbiological

    • Chemical

    • Globalisation

    • Control and regulation

    • Mycotoxins

    • Crime and fraud

    • Technology (e,g. Nanoparticles)

      • Note that technology is also seen as a solution to mitigate food safety problems…

Go global conclusions1
Go-Global Conclusions Consequences…

  • Capacity and capability building regarding emerging food riskidentification and management needsto be included in development agendas for donor countries and institutions.

  • Deviations from global rules may be acceptable for products destined for local use

    • e.g. via a tiered systems of approval for local compared to global use of food products.

  • A formal framework for dealing with national/regional exceptionsto global rules needs to be developed.

  • However, Go-Global Stopped short of gap in evidence identification and identification of policy requirements

Emerging food risk driver hazard
Emerging Food Risk: Driver – Hazard Consequences…

  • The Global Recession:

    • Increase in food fraud?

    • Domestic storage (foods used longer)

    • Conflicts between sustainable use and safe use?

    • Emerging technologies

      • Conflict between societal concerns and technical assessments?

Risk identification for existing safety risks
Risk identification for Existing Safety Risks Consequences…

  • Infosan (WHO)

    • The international Food Safety Authorities Network

  • RASFF (EU)

    • Rapid Alert System for Food and Feed


    • Global Information Early Warning System

      How effective are these combined systems?

      Where are gaps identifiable?

      Are there associated capacity building needs?

Example driver food fraud
Example Driver: Food Fraud Consequences…

Emerging research needs:

  • Understanding the motivations of fraud and identification of vulnerable links in the food chain:

    • Temporal variation

    • Regulatory variation

    • Geographical variation

    • Variation in economic motivation (is it worth it..)

  • Developing predictive models to detect fraud

  • A database of methods, spectral data and a RASSFs like notification system of detected fraud

  • A risk based sampling system

  • New technologies for detection and identification of adulteration, substitution and geographic origin of foods

Example driver food fraud1
Example Driver: Food Fraud Consequences…

Capacity Building:

  • Training in detection and prevention methods

  • Training in risk identification and development of sampling strategies

    Evidence needed for policy development:

  • Estimates of its extent and effect

  • National/ EU/ International policy based on risk assessment, management and communication

    National/International policy gaps:

  • It is a sensitive subject therefore investigation fraught with difficulty.

  • Very little harmonization of (international) approaches to deal with food fraud

  • Need for a global analysis

Collab4safety delphi
Collab4Safety: Delphi Consequences…

  • The Collab4Safety Delphi is particularly interested in:

    • Duplication of effort and lack of harmonisation regarding existing research practices

    • Gaps in international research and training needs, including capacity building and infrastructure requirements

    • Critical success factors and identification of barriers pertinent to effective policy translation.

    • Identification of emerging food safety issues which have regulatory and legal implications, as well as the consequences of such regulations for policy development.

Delphi a foresight activity
Delphi: A Foresight Activity Consequences…

  • A foresight activity that is aimed at:

    “development of international consensus regarding risk identification, risk assessment and risk management activities with respect to emerging food safety risks”

Defining delphi
Defining Delphi: Consequences…

  • A procedure to:

    “obtain the most reliable consensus of opinion of a group of experts … by a series of intensive questionnaires interspersed with controlled opinion feedback”

(Dalkey & Helmer, 1963, p.458)

Delphi methodology
Delphi Methodology Consequences…

  • Internet-based survey, with several ‘rounds’

    • Including feedback of participants’ views

    • Anonymous responses

  • Advantages:

    • Allows inclusion of many geographically dispersed experts

    • Pre-empts difficulties with group meetings

      • Unequal contributions of members

      • Unstructured data collection

(Rowe & Wright, 1999)

Applying delphi to collab4safety
Applying Delphi to Collab4Safety Consequences…

  • First round:

    • “flag up” important issues for follow up

  • Second round:

    • Focus on specific and highly relevant issues

    • Quantify differences in opinion

    • Provide feedback on the views of other participants, particularly for issues where consensus has not occurred

    • Identify directions for the future

Applying delphi to collab4safety 2
Applying Delphi to Collab4Safety (2) Consequences…

  • Data base – approximately 1000 experts internationally….

  • R1: 500 experts approached re: inclusion

  • Selection criteria:

    • Expertise
