Examination of witnesses
(Questions 260 - 267)
MONDAY 8 MARCH 1999
PROFESSOR PHILIP
JAMES and DR
ANDREW CHESSON
Dr Turner
260. Do you think the principle of substantial
equivalence to assess the safety of novel foods is satisfactory,
both for food safety and consumer confidence?
(Professor James) Answer, no, and we set out in detail
why we think that there are new approaches to that. One can get
into a wonderful, four-hour debate on what one means by substantial
equivalence and its implications in the regulatory process for
sifting data. I do not know whether Dr Chesson would like to add
anything on that.
(Dr Chesson) Yes, I think there is a tendency to assume
that all genetically modified foods are equivalent and much the
same thing. I think there are some areas in which substantial
equivalence plays a much more important part than in others. I
do not particularly have any great concerns about the relatively
few constructs which have gone through the regulatory systems
in the UK and in Europe to date, but I think we are looking at
such a very large, potential range of transgenic crops and foodstuffs
in the future that I think the whole concept, the framework, of
substantial equivalence will assume increasing importance. And,
I think, used in the way that it is currently used, I do not think
it will necessarily be adequate for that purpose.
261. Do you want to see any changes, that you
would want to recommend, to both the principle and the practice
of the Advisory Committee on Novel Foods and processes' assessments?
(Professor James) We proposed in our papers that,
in fact, there needs to be a much more proactive approach to developing
novel science, which, as it were, goes in parallel with these
exciting developments in molecular biology. And we believe that,
in fact, there is a series of scientific technical innovations
that can be applied to enhance the confidence that we have that
there are no unpredictable effects, as a result of transgenic
inserts. And Dr Chesson, as a result of his detailed analysis
of the various portfolios being put forward, and because he is
involved both personally and in an Institute that is involved
in trying to develop these novel techniques, we actually believe
that there are mechanisms now that are coming into play that we
should actually begin to use, and would give greater confidence
both to the professionals and to the public.
Mr Jones
262. Can I ask you about labelling of GM foods.
What changes would you like to see, and how far should labelling
go? Should you, for instance, have to label products which are
not genetically modified, apart from the root of the product,
which might be modified, in order to make it less attractive to
pests, or frogs, or whatever?
(Professor James) I think that the issue of labelling,
in terms of GMOs, is at present a mechanism whereby people might
be allowed to discriminate, and it is a standard response which
is totally to be expected. But where we come from is that, as
you look at what is happening out there, I find it very difficult
to believe that any labelling mechanism is going to be of any
use in ten years' time. And that is why we have spent so much
time trying to think how to enhance the safety assurance of the
GMO process. We think that that is more important than trying
to devise ever more complex and, essentially, difficult systems
to monitor GMOs. I do not believe that in the future this is going
to be possible, unless you create a complete, separate food system,
where, under no circumstances, are GMOs used at all. Otherwise
there are going to be GMO plants throughout the food chain.
Dr Jones
263. But that will not work for products that
have already been approved, will it; we will still need labelling
for those?
(Professor James) Sorry. That is why I prefaced my
remarks. I think there is labelling now, and the standard response
is: "We must have labelling", fine, I am not against
labelling. I am just saying that, actually, if you look at it,
I do not think it is going to work. That is all I am saying.
Dr Williams
264. First, I just want to tag on something
to that area. You say that, in ten years' time, you take it that
there is an absolute inevitability that our food production, in
ten years' time, will be dominated by GM crops?
(Professor James) I did not say dominated, but that,
in fact, there would be so many GM crops that they would, essentially,
pervade the food chain.
265. My next two or three questions are on the
proposal by the Royal Society, amidst others, that there ought
to be some overarching body, above the Advisory Committee on Novel
Foods and Processes, above ACRE and above, perhaps, the Food Standards
Agency, too, in this area. What is your view on that proposal?
(Professor James) As I put in our report, I think
that, obviously, it is important to have the linkages made, but
I do believe, at the moment, and Dr Chesson may disagree with
me, that the environmental issues are really very complex and
very different from the health issues. Therefore, I see that the
health issues will predominantly relate to the Food Standards
Agency, but I do believe that the overarching system proposed
by the Royal Society, in effect, under my original proposals,
would be dealt with by virtue of conjoint groups, between Environment
and Food Standards Agency, for example.
266. Where would consumers fit into that structure?
(Professor James) That is the beauty of the Food Standards
Agency, if it goes through, the consumer representation, public
interest representation, is extremely important, and that is why
it should be there.
267. Right; but we heard earlier on that the
Advisory Committee on Novel Foods and Processes has one consumer
representative, one ethics specialist, and, otherwise, I do not
know, eight or ten food company and academic scientists in this
field. What kind of balance would you see within the Food Standards
Agency and within, if there were to be an overarching body, should
not the consumers have something like a third of the total representation,
not just a token one?
(Professor James) I think it is important that I make
a distinction between consumer and public interest, I think it
is better to talk about the public interest, not just about consumer
groups. I think that I have never thought it wise to specify a
proportion, but I totally agree with you that tokenism is inappropriate,
and I do believe that, if the public, in Britain, and, indeed,
in Europeit is the sameif we are going to make any
headway, in terms of trying to properly allay and not simply con
people, I think there is a need for a completely different process.
And that is why, to go back to the Pusztai affair, for me, personally,
it was so tragic, because, in fact, there are legitimate issues
of science which Dr Pusztai had contributed to so marvellously,
and the question is how to get these legitimate interests locked
into a process. I have been trying to do that for quite some time.
I do not think we have got it right, and I think we are going
to have to evolve a system, because if we do not do things better
than we do now we are going to be running into a crisis every
few months.
Chairman: I am going to finish there,
and I am going to finish on that note, because I was delighted,
Professor James, that you felt generous and honest enough to finish
with a tribute to the work of Dr Pusztai over all the years that
he has been an experimental scientist. And, although there has
been controversy in these last few weeks, it is very heartening,
I think, for this Committee to hear you pay tribute to Dr Pusztai
in that way at this time. However, may I thank you for your evidence
this afternoon and the evidence you gave us in writing before
the Committee meeting; can I thank you, too, Dr Chesson, for the
support you have given; and thank you both for assisting us in
this difficult but very interesting inquiry. Thank you.
