In addition, one sample of artificial vinegar containing
worms was submitted to the British Museum. The worms were
found to be the "vinegar eel" - Anguillula Aceti (Müller 1783)
also called Turbatrix Aceti (Müllier) Peters, 1927.
Nothing definite is yet known concerning the origin of
eelworms in vinegar, and there is no evidence to show that
these worms are pathogenic to man.
The artificial vinegar from which the sample was obtained
was made up by a caterer for use in his business, and the
barrel in which it was being made had been in use for some
considerable time. The owner readily agreed to destroy all
stocks and to replace the existing barrel by a new one.
Ice Cream.
The number of ice cream premises registered in the Borough
is 240, of which 37 are registered for manufacture, 200 for
sale, and 3 for storage only. 372 inspections were carried out
and 17 notices served for cleansing and other requirements.
99 samples of ice cream were taken for bacteriological
examination. 3 of the samples were examined in connection with
a food poisoning inquiry, but no trace of any food poisoning
organisms could be found in them. The remainder were graded
as follows:-

The figures in parenthesis show the numbers for 1949.
Improvement in the bacteriological standard has been
maintained; 27 per cent of the samples examined were graded
3 and 4. The percentage in 1949 was 45.1, and in 1948, 61.1.
96 samples submitted for chemical analysis showed a fat
content as follows:-

The average fat content of all samples examined was 9.54
