with the requirements of the Milk (Special Designations)
Order. He produced a report on a sample which
had been taken from the same consignment and submitted
to the Company's bacteriologist. This report stated: "The
total bacterial count is low and the absence of B.Coli from
one-tenth c.c. is very satisfactory. It satisfies the Ministry

to two different laboratories.
The reports from all three bacteriologists showed all the
samples to be satisfactory in regard to both total bacterial
count and B. Coli.
One of the wholesaler's laboratories reported that on
microscopic examination a few streptococci were found in
each sample, but the other two laboratories failed to identify
these organisms.
It will be seen that the Council's bacteriologist found
streptococci in milk from Chippenham, but no other
creamery, and that the wholesaler's bacteriologist found
these organisms in milk from Chepstow and Savernake, but

On 12th February I received information from the

out of a total of 41 cows in milk, no less than six were
found to be affected with mastitis.
A prohibition was immediately placed on the use of
milk from any of these cows. It was further stated that
the majority of these cows must have been giving bad
