N.B. One sample was not suitable for the methylene blue
test owing to its colour, but was found to be free from B. Coli.
In addition to the above, 32 samples of ice cream were
submitted for chemical analysis; three of these were found not
to comply with the prescribed standard and further action was
taken.
