The results indicate a higher proportion of lower graded samples than
has been the experience in recent years. It confirms the opinion that an
extension of any part of the manufacturing process which entails the
cleaning and sterilisation of machines requires training and supervision
which is not so easy to control when it takes place in widely separated
situations as it is when concentrated in comparatively few factories. Of
the balance of the samples taken and submitted to the methylene blue test
6% were graded in provisional grades 3 and 4 as against 14% during 1961.
Although Bacillus Cereus was undoubtedly responsible for some of these
lower grading a greater selectivity in the quality of ingredients has been
responsible for the improved results.
Samples of milk were submitted to the Public Health Laboratory for
