1 MRLs.

3 MS. STEEL: I do not think I asked it clearly enough. Has
4 there been pressure to raise the MRL or lower the MRL?
5 A. Yes, there has been by various interests because,
6 obviously, if you raise the MRLs it would make it easier to
7 get away with the residues. Others of us, well, others
8 like myself, who said that in good practice one should be
9 constantly reducing the MRLs because you should not be
10 getting these residues coming through.
11
12 Q. What was the end result? Were the MRLs raised or not?
13 A. It was really love-all; they were left the same.
14
15 MR. MORRIS: Could we say if this is in the kidney, what are the
16 implications for it being available in the food that is
17 consumed by the public?
18 A. Well, if pigs' kidneys are consumed -- sorry, I could
19 not hear that.

21 MR. RAMPTON: I am sorry, my Lord, not by McDonald's customers.
22 Pig offal goes nowhere near a McDonald's shop.
23
24 THE WITNESS: The pigs' kidneys are examined because that is the
25 likeliest area. You cannot expense of testing 100 tests on
26 one pig carcass and the odd offals is very high. So, you
27 normally test the organ where you think you are going to
28 get the best marker. So, with sulphur drugs you would go
29 for the kidneys primarily, but the other organs, the liver,
30 might have some in. That is the other organ you look at
31 particularly.
32
33 MR. JUSTICE BELL: Do you have any evidence of residues being
34 found in the edible flesh of the pig, not the offal?
35 A. I have not offhand. There are green books published by
36 the Ministry.
37
38 Q. Do you have any soundly based opinion with regard to such
39 residues being found in the edible flesh of the pig?
40 A. I have not without looking it up. I cannot produce it
41 off the top of my head, only in the offals.
42
43 MR. MORRIS: But when they set these, when they look at the
44 kidneys, are they saying that if it is above the minimum
45 residue level, do not eat the kidney, or are they saying
46 that that affects the whole pig and that that pig should
47 not be on the market?
48 A. It is a marker to save you having to do tests on
49 everything that, by experience, one has found that the
50 kidney is probably the place where the residues will
51 accumulate most and quickest. It is a cheap test to do, so
52 that it is, in practice, probably the best you can do.
53
54 Q. Yes, but the point is the flesh of the pig, if the kidney
55 is over the limit, does that mean there are residues in the
56 flesh as well?
57 A. It would indicate, yes, that at various amounts there
58 were other residues, but primarily it would tell you that
59 the farmer had not been withdrawing -- he had not been
60 observing withdrawal periods as he should. He had been
