International Irradiation Initiatives The Past and Future Role of International Organisations in Food Irradiation Development Gary Luckman
2
Past and Present FIRST PROPOSAL: use irradiation to avoid the introduction of a pest by Koidsumi. Formosa, 1930 International Standard for Phytosanitary Measures: (ISPM No. 18), IPPC, 2003
3
Other Proposals Balock (1956, 1966): to use as a commodity treatment for Fruit flies in Hawaii Macfalnae (1966 ): to use as a treatment for Queensland fruit fly (Bactrocera tryoni) in Australia
4
Opportunities The ban on Ethylene dibromide by EPA (1982) Caused cancer The phase-out of methyl bromide by the MONTREAL PROTOCOL (1992) Depletion of the ozone layer Development of an international standard- setting program in the IPPC (1992)
5
Implementation 1930 2005 First proposal First routine international shipments 1970 FAO/IAEA 1980 JECFI ISPM No. 18 2003 70+ years
6
Alternative Treatments Chemical fumigation (EDB and MBr): health and environmental problems Hot water treatment: limited applications Modified atmosphere: damages tropical fruit Refrigeration: long periods Irradiation: universal
7
Costs TreatmentUS$/Ton Hot water250 Steam treatment200 - 250 Refrigeration46 - 600 Controlled atmosphere50 - 600 Irradiation25 - 55
8
Historical efforts Safety of irradiated food Effectiveness as a phytosanitary treatment Support of international organizations WHO, FAO, IAEA Technical capacity building ICGFI National Regulations Regional and International standards, Codex Alimentarius, NAPPO, IPPC
9
Effectiveness First based on standards for other phytosanitary treatments (e.g., fumigation) Probit 9 (99.9968% mortality) Disadvantages Level of security was very high Not always possible to work with the large number of pests
10
New concept Irradiation provided a phytosanitary treatment with different options for a desired response: Inability to emerge or to fly Sterility Inactivation
11
Research Projects sponsored by the FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. Research in different countries US publishes research showing 150 Gy as Dmin for Oriental fruit fly, Mediterranean fruit fly and Melon fly, based on “non- emergence of adults (1966)
12
FAO/ IAEA Joint Division International Coordinated Research Programs (CRP) 1984-1989 “Use of Irradiation as a Quarantine Treatment for Fruit Flies and Other Arthropods” 1992–1997 “ Use of Irradiation as a Quarantine Treatment Against Pests such as Mites, Thrips, Weevils and Nematodes 2009 -2013 “Development of Generic Irradiation Doses for Quarantine Applications”
13
ICGFI International Consultative Group on Food Irradiation Established under the aegis of FAO, IAEA, and WHO (1984-2003) Constituted of experts in food irradiation designated by the governments of different countries
14
ICGFI Functions To evaluate global developments in the field of food irradiation To provide a focal point of advice on the application of food irradiation to member states and the organizations To furnish information to the joint FAO/IAEA/WHO Expert committee on the Wholesomeness of Irradiated Food, and to the Codex Alimentarius Commission
15
ICGFI - Work Task Force to evaluate treatments Workshops Support Economic Feasibility Studies in countries with potential to install irradiation treatment facilities Collect/create, edit, print and distribute technical documents
16
ICGFI Task Force 1984 - Evaluated efficacy data on fruit flies and other arthropods and on phytotoxicity Recommended 150 Gy Dmin against fruit flies in the Trephitid family and 300 Gy for other arthropods 1991 - evaluated additional data, reaffirmed the generic doses proposed previously 1994 - Developed a guideline protocol to use irradiation as as quarantine treatment for commercial fruit and vegetables
17
Harmonization ARCAL PROJECT: Proposed in Mexico, 1998 1999-2000, participation of 7 countries from the Latin American Region in elaborating “Harmonized Quarantine Regulations for Irradiated Food” Objective: to develop a harmonized research and certification system to facilitate trade in irradiated fruit Guidelines for elaborating research protocols for the use of ionizing radiation as a quarantine treatment for fresh fruit Certification Protocol for irradiation as a quarantine treatment for fresh horticultural products
18
Education IAEA Inter-Regional Workshops: Objective: To inform senior food control and plant quarantine officials of a systematic approach in certifying irradiation as a sanitary and phytosanitary treatment to facilitate trade in food and agricultural commodities Philippines, Morocco, Mexico, Australia, Brazil from 1999 - 2008
19
Harmonization IAEA Documents: Guidelines on Irradiation as a Quarantine Treatment of Fresh Horticultural Commodities Guidelines on Certification of Food Irradiated for Other than Phytosanitary Purposes Guidelines Providing Criteria for the Certification of Irradiated Foods
20
International Standards Codex Alimentarius (Codex) International Plant Protection Convention (IPPC)
21
National regulations 40 countries have general legislation and regulations for the irradiation of food Only a few countries have regulatory systems for phytosanitary treatments
22
Why is irradiation different? Dose is not commodity specific Based on Dmin for the pest Dmin is established through dose mapping Dmin is assured through dosimetry No immediately observable effect on pest Options for desired response
23
Options for desired response Mortality (not necessary for Q-security) Sterility or limited fertility Limited development Non-emergence Devitalization (of seed) Inactivation (of microorganisms) Sprout inhibition
24
Reg. design for irradiation treatments Generic doses are possible: For any pest across all commodities* For groups of pests Regulations on a pest/commodity basis are therefore artificially limiting Regulations requiring commodity by commodity evaluation for food safety are unjustified *provided commodities tolerate the dose
25
Non-phytosanitary Food safety Nuclear regulatory concerns Quality (except where phytotoxicity makes a treatment impractical) Consumer labeling (except to the extent that phytosanitary treatments require such labeling under other authorities)
26
Trade Few commercial tests: Mango and Papaya from Australia to NZ Guava from Mexico to the USA ISPM No. 18 established in 2003 as a global reference United States -- Framework Equivalency Work Plan (FEWP) for imports from India, Thailand, Mexico and other countries

28
The Future Pending research work Dmin needed for specific pests Tolerance dose for exotic fruits Combination treatment studies Campaigns to educate consumers, producers, investors, and regulators in importing and exporting countries Business analyses for new facilities
