Analyst for examination.One sample was found to be below the legal standards laid down,
and a warning letter was sent to the vendor.
Channel Islands and South Devon Milk
The Milk and Dairies (Channel Islands and South Devon Milk) Regulations, 1956,
require that all milk for human consumption sold under the specific description of 'Channel
Islands Milk', 'Jersey Milk', 'Guernsey Milk' or 'South Devon Milk' must contain not less
than four per cent, by weight of milk fat. This compares with the presumptive milk fat
standard of three per cent, specified for ordinary milk by the Sale of Milk Regulations,
1939.
The following table shows the average percentages of milk fat and non-fat solids of the genuine samples taken during each month:
