The methylene blue test does not provide a guarantee of safety but it
does serve as a simple and practical method of grading ice-cream according
to its degree of bacterial cleanliness and samples which consistently
fail to reach grades I or II give reasonable grounds to indicate defects
in manufacture or handling requiring further investigation. The
certificate giving the results of testing has the following note appended:
"Owing to the numerous factors governing the hygienic quality
of ice-cream it is unwise to pay too much attention to the
bacteriological results of any single sample,, Judgement should
be based rather on a series of samples. It is suggested over a
six monthly period 50 per cent of vendors samples should fall into
grade I, 80 per cent into grades I or II, not more than 20 per cent
into grade III and none into grade IV".
