Caseous Lymphadenitis.—This disease, sometimes called
" pseudo-tuberculosis" occurs mainly in sheep although it is
occasionally found in cattle, rabbits and chickens. It is met
usually in imported sheep carcases and is often the cause of meat
being rejected as unfit for human consumption. It follows, therefore
that much time and attention is given by the Food Inspectors
to this disease during their inspections at the wharves and cold
storage plants in the Borough.
Results of examinations for caseous lymphadenitis are given
below.

Imported Egg Products.—As a riparian authority Greenwich
receives substantial landings of these products and although since
the introduction of the heat chamber treatment dried egg albumen
no longer presents any serious problem, great difficulty arises in
connection with the effective sterilisation of frozen whole egg, frozen
liquid albumen, spray-dried whole egg and spray dried egg yolk.
In this connection it has been found scientifically unsound to
draw any conclusions on the bacteriological purity or otherwise of
consignments sampled in accordance with present methods which
are not only tedious but often technically difficult and productive of
laboratory results which are most equivocal. A satisfactory outcome
is arrived at in some countries where egg products are subjected
to pasteurisation before processing but, as far as is known, no such
pasteurising plants exist in China, a country whose egg exports are
causing us such concern.
