INSIGHTS Implications Cariadal U.S.A. Trade Agreernent for The elements of a Trade Agreement between Canada and the U.S.A. were agreed to on October 3, 1987. With respect to the elements, the following is a brief synopsis of the items that have significant implications for the fisheries: Tariffs: Some fisheries tariffs are scheduled for immediate elimination, others will be eliminated over a five- year or ten-year period. The main tariff item of significance (U.S.A. 10% and 15% tariffs and Canada's 11% and 17.5% tariffs on fish sticks, portions, prepared meals, etc.) would be elimi- nated over the ten-year period. Investments: The Parties agreed to provide each other's investors national treatment with respect to establishing a new business, buying an existing bus- iness, operating and selling an existing business. However, all existing laws, regulations, published policies and practices not in conformity with this obligation are grandfathered. Therefore, Canada's policy that fishing vessels must be owned by a majority of Cana- dians remains. With respect to the pur- chase of Canadian fish processing plants by U.S.A. investors, currently the only requirement is that the purchase of processing assets over $ 5 million must be first reviewed by Investment Canada. This review requirement will rise over four years to the $150 million level. Countervail/Subsidy Laws: No changes. The countervail and subsidy laws in place at the time the treaty is ratified will generally apply to Canada/U.S.A. trade for the succeeding five years while the two sides attempt to develop a specific Canada/U.S.A. countervail and subsidy code. During the course of the treaty, changes to countervail and dumping laws can apply to Canada/U.S.A. trade only if the legislation changing the laws specifi- cally states the changes apply also to Canada/U.S.A. trade. Dispute Settlement: Minor change. Countervail complaints will still be investigated by U.S.A. Commerce and U.S.I.T.C. according to current U.S.A. countervaillaws at the time. However, if the Canadian export industry believes the above bodies have ruled incorrectly vis-a-vis U.S.A. laws, the Canadian 120/ lA export industry can appeal to a bi- national panel comprised of five judges, of which at least two are from Canada. At present, the Canadian export indus- try can appeal to the U.S.A. interna- tional trade court in New York - which the Fisheries Council of Canada is presently doing regarding certain sub- sidy findings by the U.S.A. Commerce Department in the fresh groundfish countervail case. Trade Restrictions: With rspect to import restrictions in fisheries products, the only restrictions allowed are those for health, safety, and the conservation of the resource. With respect to exports, restrictions can be imposed on the basis of short supply and the con- servation of the resource. However, such export restrictions must provide the sharing of the resource with the other Party. All existing quantitative restrictions not consistent with the above Agree- ment will be either eliminated (immedi- ately or by an agreed timetable) or grandfathered. Inputs: All agricultural tarifs will be eliminated within 10 years. Canada will eliminate import licenses for wheat products as soon as the support levels for these products in both countries are technically equal. Standards: Standards and regula- tions are allowed to protect health and safety, environmental, national security, and consumer interests. However, these measures must not operate to exclude goods of the other Party that meet these objectives. Fisheries Council of Canada's Reaction: As an export industry heav- ily dependent on unfettered access to the U.S.A. seafood market, the Fisher- ies Council of Canada has been highly supportive of the initiative to establish a formalized special trading relationship with the U.S.A. This has been particu- larly true in recent years as threatening trade legislations have been proposed in both the U.S.A. Congress and Senate. There is no question that the eventual elimination of the U.S.A. tariff on sticks, portions, and seafood prepared dinners will lead to improved efficiencies, ena- bling the current Canadian producers of these products to better rationalize production and eventually lead to increased employment in Canada. It may also open up opportunities for medium size processors to become involved in the processing of these products, either under their own brands or for brands currently well established in the U.S.A. market. However, before a final assessment of the Treaty can be made regarding its potential impact on Canada's fisheries, we must first have the detailed legal document and, more specifically, determine what legislation and non-tariff items on both sides of the border are eliminated or grand- fathered. U.S.A. Groundfish Restrictions On October 1, 1987 the U.S.A. National Marine Fisheries Service introduced minimum size possession restrictions on certain groundfish and flatfish species as part of its groundfish management plan. The restrictions also applied to imports. The minimum sizes are: cod, haddock, pollock - 19", yel- lowtail flounder and American plaice _ 12", witch flounder - 14", and winter flounder - 11". These restrictions have proved difficult for many U.S.A. New England fresh fish processors who depend on these imports from Canada. Conse- quently, considerable discussion is cur- rently taking place in New England Management Council to address the problem. One approach recommended was to impose equivalent minimum size possession restrictions on fresh fillets of the designated species. However, it now appears that the New England Management Council recognizes that (i) such an approach would cause even greater hardship to New England fresh fillet processors; and (ii) it is almost impossible to develop a verifiable fillet equivalent size; and (iiil such restric- tions are against the U.S.A:s GATT obli- gations. Both the Canadian and Icelan- dic governments voiced their objections to the U.S.A. State Department to any move by the U.S.A. to restrict fillet imports.

BackgroundAs a food processing technology,

irradiation has been studied during thepast 40 years. Internationally, 32 coun­tries have approved irradiation for usewith one or more food products, 11have a commercial program and about25 facilities treat food on a commercialscale.

There has been renewed internationalinterest in food irradiation as a methodof improving the· safety, quality andshelf-life of foods, mainly because oftwo recent developments:1. The conclusion of the 1981

FAO/IAEAIWHO Expert Committeethat foods irradiated up to an over-

all dose of 10 kGy were wholesome(details discussed below).

2. The banning of fumigants such asethylene dibromide (EDB) in manycountries, making the search foralternative methods of insect con­trol a priority. This will have a sig­nificant effect on trade patterns,especially for Third World countriesthat ship fresh produce to NorthAmerica and Europe.

The irradiation processIrradiation is a process whereby

foods are exposed to ionizing radiationto achieve a variety of effects depend­ing on the dosage.

Ionizing radiation is capable of break­ing molecules into smaller ionized orelectrically charged particles. Thesources of ionizing radiation availableto treat foods are X-rays, acceleratedelectrons or more commonly, gammarays emitted from the radioisotopescobalt-60 or cesium-137.

Irradiation affects food products atthe cellular level. For potatoes, onionsand garlic, ionizing radiation interfereswith cell division and thus preventsgrowth of sprouts during storage. Forfresh fruit, ionizing radiation affects the

ripening and aging process, therebymaintaining quality and extending theshelf-life. Ionizing radiation also breaksdown some of the chemical bonds inorganisms that contaminate food,thereby reducing the number of patho­genic micro-organisms in meat, fish,poultry and spices, and kills or renderssexually sterile insects in grains, spices,fruits and vegetables.

ApplicationsCurrently, no food is being commer­

cially irradiated in Canada for the mar­ketplace nor are any irradiated foodsknowingly being imported. Commercialuse of food irradiation depends on anumber of factors including the tech­nical effect on food, the existence ofdemand for the benefits provided, com­petitiveness with alternate processesand the willingness of consumers tobuy irradiated food products. Foodirradiation will not solve all of our foodproblems. It will not replace widelyused food processing techniques.However, it will add to the choices wehave to improve the quality and safetyof our food supply.

Not all foods are good candidates forirradiation, just as not all foods are

suitable for other physical processessuch as freezing or canning. For exam­ple, dairy products are more sensitiveto the process and develop off-flavors.Irradiation can also cause softening anddiscoloration in some fruits and vegeta­bles.The efficacy (ability to produce adesired effect) of food irradiation hasbeen demonstrated for certain applica­tions which the food industry may tryto employ. These include the irradiationof meat to greatly reduce pathogens,such as Salmonella in poultry, the irradi­ation of strawberries to delay moldgrowth and extend shelf-life and theirradiation of fruit and vegetables toreplace the chemical fumigants such asethylene dibromide for deinfestation.For the food industry, these functionalbenefits translate to potential benefitssuch as reduction in waste, lower costs,expanded markets and higher qualityfoods.

Irradiation of foods still requires goodmanufacturing and handling practices.While the process reduces, inactivatesor destroys the initial microbial popu­lation, there is no residual protectionagainst recontamination from improperhandling. Meat and fish products will

still require refrigeration although theywill have a longer shelf-life.

Once a product is irradiated, properpackaging is also essential to maintainthe product in an optimum state. Pack­aging research has centered on findingflexible, lightweight containers capableof withstanding handling and storagewhile retaining their protective qualities.

Chemical, physical and microbiologicalstudies are conducted to ensure safetyof the final packaged products.

Industry ReactionFood industry reaction has been cau­

tious towards food irradiation technol­ogy. Industry is waiting to see howgovernment regulations, specificallythose concerning labelling, will bepromulgated. Industry does not want tobegin using a process that consumersview negatively. However, recent con­sumer research indicates that con­sumers are willing to learn more aboutfood irradiation. Recently, industry hasformed the Canadian Council for theAdvandement of Food Technologies.The council will be focusing on irradia­tion as one of its programs. The coun­cil's mandate is to provide the public,legislators and the media with credibleinformation on food technologies.

Consumer ConcernsConsumer concerns about safety

have centered on two issues - whole­someness and the inducement or radio­activity in foods. With respect to thelatter, energy levels of the approvedsources for food irradiation are too lowfor radioactivity to be induced in foods.With respect to the former, when foodsare exposed to ionizing radiation, sub­stances called radiolytic products areformed. Radiolytic does not meanradioactive. The term refers to productsthat are formed when foods are irradi­ated. Studies from various experts haveshown these products to be the sameas those occurring naturally in freshfoods, or the same as those resultingfrom other processes such as heating,frying and broiling. To date, no uniqueradiolytic products have been found inirradiated foods.

Critics of the process, on the otherhand, maintain that long-term safety inhumans has not yet been proved. Theyclaim that uncertainties about safetyremain because of poor test design andmethodologies. However, in 1981, anExpert Committee of the World HealthOrganization (WHO), the Food andAgriculture Organization (FAO) and theInternational Atomic Energy Agency(IAEA) engaged itself in a review of thedata accumulated over the past40 years. The Expert Committee con­cluded that irradiation up to an overalldose of 10 kGy presents no toxicologi­cal hazards and introduces no specialnutritional and microbiologicalproblems when compared to other con­ventional processes. Data were insuffi­cient to formulate conclusions on appli­cations of food irradiation above10 kGy.

Low dose applications up to 1 kGywill inhibit sprouting, control insectinfestation and delay ripening. Mediumdose applications up to 10 kGy willreduce the microbial load and the num­ber of pathogens (such as Salmonella).High dose applications greater than10 kGy will sterilize foods.

Proposed RegulationsIn Canada, provision has existed underthe Food and Drug Regulations sincethe mid 1960s for the irradiation andmarketing of potatoes and onions toinhibit sprouting, and for the treatmentof wheat, flour and whole wheat flourto reduce insect infestation. Provisionwas made in 1984 for the irradiation ofspices to reduce bacterial contamina­tion. Recently a petition was submittedto Health and Welfare Canada forpoultry irradiation to eliminateSalmonella and other pathogens andextend the shelf life. Health and WelfareCanada is currently reviewing the sub­mission.

As a result of the International ExpertCommittee's findings on the safety offood irradiation technology, Health andWelfare Canada, the federal depart­ment responsible for the Food and DrugRegulations, proposed in 1983 thatfood irradiation should no longer becontrolled under the existing food addi­tive provisions. Instead, separaterequirements are being considered byHealth and Welfare Canada to specifi­cally regulate this technology as aprocess. To address wholesomenessconcerns and to ensure optimum qual­ity and safety, the proposed regulationsset out clearly the basis of proofrequired for submissions on new usesof irradiation. It is proposed that toxico­logical testing will not be required fordoses up to 10 kGy. It should beemphasized that no relinquishing ofcontrol of food irradiation from a publichealth point of view will occur if theproposed regulations are adopted.

Regulations concerning labelling offoods lies within the jurisdiction of Con­sumer and Corporate Affairs Canada(CCAC). Much discussion with indus­try and consumer groups has takenplace regarding the type of labelling toadopt. The CCAC position has beenthat all irradiated products to be sold toCanadian consumers will be clearlylabelled, but the issue of how to labelproducts containing irradiated ingre­dients is still outstanding. What is cer­tain, is that consumers will be given theoption to decide for themselveswhether or not they wish to buy irradi­ated products. CCAC issued Commu­nique No. 50 in 1985 outlining the listof labelling options being considered.

Other Government ActivitiesIn June of 1986, an interdepartmen­

tal advisory committee led by Agricul­ture Canada was established. The pur­pose of the committee is to provide aforum for the exchange of information,to identify needs and to recommendcourses of action to be taken in areassuch as regulations, economic and mar­ket impact analyses and research.Agriculture Canada has also esta­blished a committee to coordinateactivities on food irradiation within thedepartment. One of the issues that thecommittee will be investigating is thepotential non-tariff trade barriers thatcould be created by the irradiation regu­lations of our trading partners.

Future DirectionsIf all elements of the marketplace ulti­

mately agree that irradiation has a role,then the food industry requires the sup­port of applied research. To ensure opti­mum quality of irradiated foods, thereis a need for translation of small-scalelaboratory experiments to large-scaletrials under commercial conditions.Agriculture Canada has established 'aresearch and development food irradi­ation facility at the Saint-Hyacinthe

Laura Wallcraft

Food Research Centre in Quebec. Thisfacility is available to industry for their

, own research projects and for trainingtechnicians in the operation of foodirradiation equipment. A demonstrationfacility for food irradiation, the Cana­dian Irradiation Centre, was opened inMay 1987 at Laval, Quebec. ThisCentre is a non-profit project jointlysponsored by Atomic Energy of CanadaLimited and the Institut Armand Frap­pier for the promotion of radiationprocessing technology.

Food irradiation as a processing tech­nology offers some advantages overconventional processing, and eachapplication will be evaluated on itsmerits. It should be noted that, as is thecase with all food technologies,Agriculture Canada is in no waypromoting this technology over others.One of the roles of the departments isto help the food industry take advan­tage of all processing technologies toensure the best quality products,thereby ensuring the competitivenessof Canadian foods both at home andabroad.

Agriculture Canada will continue tomonitor developments in food irradia­tion to ensure Canadians have a safeand high quality food supply.
