*Three samples could not be submitted for Methylene Blue Test due to atmospheric
conditions.
The Methylene Blue failures were investigated and a further programme for sampling
arranged. The disturbing factor was the number of samples from one particular
bottling plant which failed the Methylene Blue test. The milk was bottled outside
the Borough and the failures related to deliveries in bottles and churns to members
of the public and to hospital kitchens. No satisfactory conclusion as to the reason
for these failures was discovered and legal proceedings were initiated.
