(4) When tuberculous lesions are present on the pleura
and peritoneum.
(c) When tuberculous lesions are present in the muscular
system or in the lymphatic glands embedded in or
between the muscles.
(d) When tuberculous lesions exist in any part of an
emaciated carcase.
2. The carcase, if otherwise healthy, shall not be condemned, but every
part of it containing tuberculous lesions shall be seized : —
(a) When the lesions are confined to the lungs and the
thoracic lymphatic glands.
(b) When the lesions are confined to the liver.
(c) When the lesions are confined to the pharyngeal
lymphatic glands.
(d) When the lesions are confined to any combination of
the foregoing but are collectively small in extent.
The Commission add:- "In view of the greater tendency to
generalisation of Tuberculosis in the pig, we consider that the
presence of tubercular deposit in any degree should involve seizure
of the whole carcase and of the organs. In respect of foreign dead
meat, seizure should ensue in every case where the pleura have
been stripped."
These recommendations are not, in the opinion of many authorities,
sufficiently strict to be scientific and really effectual as protective
measures, and the signs of generalised tuberculosis (Section
1) are not wholly adequate. But it must be borne in mind that for
various practical reasons it is desirable, at present, to follow as
strictly as possible the findings of the Royal Commission which
form a well recognised standard.*
* It may be mentioned that in France, where these matters receive more
attention than in this country, an Order was made by the Minister of Agriculture
in 1896 recommending the total seizure of the carcase (a) when the tuberculous
lesions are accompanied by emaciation, (b) when tuberculosis exists in the muscles
or in the intra-muscular glands, (c) when generalized tuberculosis shows itself
by miliary eruptions of internal parts, particularly the spleen, and (d) when
marked tuberculosis lesions exist at one and the same time in the thoracic and
abdominal organs. Commission dc la Tuberculose : La Propagation de la Tuberculose,
