The product of one local manufacturer which did not satisfy
the methylene blue test was investigated. The cause of the trouble
was found to be a new modern type of cooler used in the process
presenting difficulty in the sterilisation of the unit.
Five samples of ice cream were obtained for chemical analysis
and all have been reported satisfactory. Examination of the ice
cream samples showed a fat content much in excess of the present
standards for fat content.
Six samples of lollies were analysed and found to be satisfactory,
free from lead and other metals.
It is encouraging to note that the producers have succeeded in
eliminating the presence of lead or compounds of lead from the
moulds necessary for the production of lollies in order to comply
with the required standard.
