2 Q. What about infectious stunting syndrome?
3
4 MR. JUSTICE BELL: Infectious what?
5
6 MS. STEEL: Stunting syndrome?
7 A. What about it?
8
9 Q. Is that a common problem?
10 A. We do see the condition from time to time. It used to
11 be quite a big problem. By and large, it only occurs
12 occasionally on farms rather sporadically. We believe it
13 is a virus condition, a small enterovirus. We do not
14 really know very much about how it is transmitted.
15
16 Q. That is something that is connected to the broiler farms,
17 is it?
18 A. Yes, it is.
19
20 Q. When you actually said farms before, you saw it on farms
21 sporadically, you were talking about Sun Valley farms?
22 A. Yes.
23
24 MR. JUSTICE BELL: All these things we are talking about are
25 within the four to six-and-a-half per cent?
26 A. They are all causes of mortality within that, yes.
27
28 MS. STEEL: Would birds necessarily die from infectious stunting
29 syndrome?
30 A. No, they would not, not necessarily. If birds are
31 suffering from it, they normally do not grow very well and
32 the normal practice would be to cull them. They actually
33 do not seem to show any outward signs, really, of disease.
34 They are just very small.
35
36 Q. What is the extent of listeriosis at Sun Valley?
37 A. Listeria as a disease does not occur in poultry.
38
39 Q. So that only affects the meat?
40 A. Listeria is an organism which can occur in meat
41 factories. It is thought that it may be a contaminant of
42 the intestinal tract of animals and birds, so it can be
43 found in slaughter premises, but it is not a disease
44 problem of poultry.
45
46 Q. But is it caused by bacteria that cause a different disease
47 in poultry?
48 A. No, it is a bacterial problem but it does not produce a
49 disease in poultry, at least not one that we see.
50
51 Q. It is a problem in the meat, though, for humans?
52 A. If meat is contaminated with listeria, listeria is
53 potentially a food poisoning organism so it would come in
54 the same category as other food poisoning organisms, that
55 it would have to be destroyed by proper cooking.
56
57 Q. What percentage of birds at Sun Valley are affected or,
58 sorry, what percentage have that contamination?
59 A. We do not know.
