A DISCUSSION PAPER BY CONSUMERS INTERNATIONAL
Prepared for the
CODEX COMMITTEE ON GENERAL PRINCIPLES
Thirteenth Session
Paris, France, 7-11 September, 1998
This document presents key findings and recommendations from a longer discussion paper, prepared by Consumers International, for Item 8 on the agenda of the Thirteenth Session of the Codex Committee on General Principles, "Review of the Statements of Principle on the Role of Science and the Extent to Which Other Factors Are Taken Into Account: Application to the Case of BST and PST."
This subject is of great interest to Consumers International and its members, both from the standpoint of general principles about how risk analysis is carried out by Codex and with respect to the specific case of BST. Consumers International thus welcomed the background paper prepared by the Codex Secretariat for this agenda item, CX/GP 98/10. Unfortunately, in Consumers Internationals judgment, CX/GP 98/10 is deficient in several important respects. It offers little in the way of a conceptual framework that can be used to assess why and how "other factors" should play a role in risk analysis, or how to determine which "other factors" should play which roles. It omits consideration of a number of important "other factors" that are quite obviously part of risk analysis. And it reaches conclusions and makes recommendations, both on general principles and with respect to BST, that Consumers International believes are unjustified.
Consumers International had largely drafted our own paper on this subject before CX/GP 98/10 was available. Our objective was to present a conceptual framework on the role of "other factors," and to examine both the risk analysis process in general and the BST case as an example, systematically identifying factors other than science that have played or perhaps should play roles in the risk analysis process.
This document presents the essence of our longer paper. The full paper will be available at the CCGP meeting in Paris, 7-11 September; the Table of Contents is appended here. Persons wishing to obtain a copy of the complete document in advance of the meeting may contact:
Consumers International has prepared this paper to address the role of science and the extent to which "other factors" should be taken into account in Codex decisions. Our primary emphasis is on the general principles that should apply to "other factors" within the risk analysis process; we also have appended a Case Study, applying the general approaches we discuss to the specific case of BST. We believe general policy on the use of "other factors" should be developed and then applied by Codex to the BST decision, and not the reverse.
It is evident to Consumers International that many "other factors" are now, and inevitably must be, part of risk analysis on food safety issues. Other factors arise and must be addressed in all phases of risk analysisrisk assessment, risk management and risk communicationand at all levels of the processinternational (Codex) decisions, decisions by national authorities, and decisions by consumers in the marketplace. In all cases, science is a necessary basis for decisions, but never a sufficient basis in itself. Furthermore, science itself is not value-free, and even analyses and decisions made by scientific bodies typically are based on both scientific and non-scientific considerations.
Consumers International believes that a policy on "other factors" in Codex decisions is urgently needed, to promote clarity and greater transparency of decisions. In particular, it is vital to improve the ability to distinguish between scientific and non-scientific portions of the basis for decisions. We hope this process now under way at CCGP will result in a clear policy that systematically identifies "other factors" that are appropriately addressed in Codex decisions, and provides guidance as to how they should be dealt with by Codex committees.
"Other factors" that are inescapably part of Codex decisions intended to protect the health of consumers include a variety of subjective value judgments and social choices in the application of risk analysis. Among the most important are how to treat scientific uncertainty, and perceptions as to which risks are "significant." Other factors include economic concerns, such as the feasibility of risk-management options, and the benefits of the activity or substance that poses the risks. Ethical issues, such as the rights and responsibilities of all the parties involved in the risk management process, also enter the picture.
In Codex decisions with respect to food labelling, additional "other factors" may apply. In particular, consumers need for and expressed desire for information on a food issue must be acknowledged and given weight. Consumer preference, per se, is not a basis for Codex to prohibit or limit the use of a food substance or technology. But recognition that consumers do have preferences based on many factors that cannot be considered by Codex provides a basis for labelling, so that consumers can exercise their preferences in the marketplace and manage their own risks.
With respect to the specific case of BST, discussion is constrained somewhat by the lack of availability to date of the full scientific report from JECFAs recent assessment of BST risks. However, based on extensive experience with risk assessment, with expert bodies and with the BST issue, Consumers International presents a general analysis, in Annex 1 of this paper, of some factors other than science that we believe are almost certainly part of the Codex risk analysis process on BST. In our view, such aspects as how to deal with the major uncertainties in the scientific data on BST risks, and judgments of whether the risks are "significant," are highly subjective, and likely to be based on "other factors," as well as on scientific evidence. We identify many "other factors" that appear likely to be part of decisions at some point in the Codex risk analysis on BST, and suggest ways to clarify what those factors are, and determine whether they have played a transparent and appropriate role in the process.
Consumers International recommends that Codex decisions on BST be held in abeyance until the following two conditions have been met:
(a) the full JECFA report on BST has been published and critically reviewed by all interested parties, and
(b) the Committee on General Principles has promulgated a policy on the role of "other factors" in Codex decisions, which can be applied to the BST case.
In Consumers Internationals judgment, these two conditions are essential for any final decision on BST by Codex to be perceived as valid by consumer organizations.
Consumers International also recommends that the Codex Alimentarius Commission refer the matter of BST to the Committee on Food Labelling, as well as to the Committee on Residues of Veterinary Drugs in Foods. If BST use is permitted, labelling should be provided to allow consumers to make informed choices.
CX/GP 98/10 states
some important conclusions about JECFAs risk assessment and its recommendations [on BST]. For example, at Paragraph 19: "
the precautionary principle
cannot apply in the case of BST as the scientific basis clearly exists." At Paragraph 24, the paper states that while "other factors" would have to be considered in conjunction with scientific evidence as a general principle, "This does not appear to be applicable to the particular case of BST where recommendations covering both risk assessment (ADI) and risk management (MRL) have been made on a scientific basis." Paragraph 19 also states "JECFA has identified no significant risk" from BST and that "no safety concern has been put forward" with respect to BST.
With all due respect, Consumers International does not accept these interpretations of JECFAs action. Other interpretations are also possible. In our judgment, until the full JECFA report on BST has been published, it is not possible to know exactly what JECFA concluded, or what the actual basis for JECFAs conclusions may have been. Nor can it be determined whether JECFAs risk assessment is scientifically sound. The report must be published, reviewed by the expert community, subjected to normal scientific criticism and debate, and discussed in the context of its implications for risk management. More than one view of those implications seems likely to be tenable. The conclusion in CX/GP 98/10 that JECFA has provided "a basis in science" which then allows Codex to follow only one course of action on BST is simply not supportable.
Consumers International believes, as outlined in our discussion paper on general issues related to the role of "other factors" in risk analysis, that one cannot conclude at present that the basis for JECFAs recommendations was "science." In all likelihood some non-scientific factors also entered into the basis for the "no ADI/no MRL" recommendation, and other factors may in fact have received great weight.
In the interests of a sound risk analysis (including effective risk communication), Codex, and in particular CCRVDF, should take no action on the JECFA recommendation until the full report has been published and reviewed. If, as Consumers International expects, a careful review of the basis for JECFAs recommendation indicates that it was based in part on science and in part on non-scientific other factors, those other factors need to be identified and examined. Codex needs to determine whether the role of other factors as a basis for JECFAs position is appropriate. To accomplish that, a most sensible approach appears to be first to develop general principles on the role of other factors in decisions, and then to examine the BST case for consistency with the agreed general principles.
Consumers International believes that both a critical examination of the basis for the JECFA recommendations and a sensible policy regarding the role of other factors in decisions are essential foundations for any eventual Codex decisions on BST. They are especially essential if Codex wants or expects consumer organisations and the public to accept its risk analysis of BST as valid and scientifically justified.
[NOTE: in the ANNEX to the full discussion paper, Consumers International provides an ample basis to presume that the Codex risk analysis process on BST to date has involved numerous non-scientific factors as well as scientific factors, and proposes an approach by which Codex and others can examine the risk analysis on BST, to identify "other factors" and ensure that they have been appropriately considered and weighted.]
Beyond that, however, there are a number of specific points in CX/GP 98/10 that need specific responses:
Consumers International believes that developing a better conceptual approach to what "other factors" are legitimate parts of the basis for decisions in food-safety risk analysis will improve the quality of decisions, improve the process for reaching decisions, and greatly facilitate risk communication about the subjects of decisions. With those goals in mind, we offer these recommendations for the Codex Alimentarius Commission and its committees and subsidiary bodies:
