(2) These Regulations shall come into operation on the 1st day
of May, 1948".
An Explanatory Note is added as follows
"(This note is not part of the Regulations, but is intended to
indicate their general purport).
These Amending Regulations remove the prohibition of the import
into England and Wales of any mutton or lamb from which a lymphatic
gland has been taken out".
Accompanying this Statutory Instrument was a Circular M.F. 1/48 from the
Ministry of Food enclosing a supplementary memorandum (Memo. 62b/Foods)
modifying the criteria of meat inspection recommended in Memorandum 62/Foods,
issued by the Ministry of Health on the 16th March, 1922.
Memo 62b/Foods reads as follows:-
"The following new Section IVa is to be substituted for that contained
in Memo 62a/Foods, dated September 1937. Memo 62a/Foods is
cancelled together with item "17® Lymphadenitis, caseous" in Section
Va of the Memorandum on Meat Inspection (Memo 62/Foods).
A. METHOD OF INSPECTION.
1. All carcases and viscera shall be examined by visual examination
and by palpation of the accessible lymphatic glands®
2® The prescapular, superficial-inguinal, supra-mammary and pre crural
lymphatic glands of sheep shall be incised and examined as a routine.
These glands in lamb carcases need only be incised if evidence of
disease is found or disease is suspected in the course of visual
examination and palpation.
B. ACTION TO BE TAKEN:
1. An organ shall be condemned when caseous lymphadenitis exists on
its surface, or in its substance, or in the associated lymphatic glands.
2. The entire carcase and all the organs and viscera shall be condemned
when the following conditions are present:-
(a) emaciation associated with caseous lymphadenitis,
(b) generalised caseous lymphadenitis.
The following shall be regarded as evidence of generalisation-
(i) The presence of multiple lesions which are acute and actively
progressive; or
(ii) the presence of multiple lesions which are inactive, but
widespread.
3. All infections not included in paragraphs 1 and 2 of B above shall
be regarded as localised, and only the lesion and the surrounding part
shall be condemned. The size of the part condemned should depend on
the age and degree of activity of the lesion. Old lesions which are
firmly encapsulated may be regarded as inactive".
Copies of the above-mentioned Regulations and Memorandum have been forwarded
to your Inspectors with instructions that they should act upon them
forthwith.
