War Surgery and Medicine
Every endeavour was made from the outset to ensure that only pure food reached the troops. Nothing in the way of uncooked vegetables and fruit that was not disinfected was to be eaten by the troops. Outside the camp they were enjoined not to eat uncooked green vegetables and onions, or any fruit which did not have a sound skin. In Cairo and other places they were advised to eat only at such approved places as forces clubs. Where fresh milk was used, boiling was insisted upon, but mostly tinned milk was used.
The ration for the New Zealand troops was the standard ration for British troops, with as a supplement certain increases made possible by the use of regimental funds for the purchase of fruit and vegetables. Variations from the British scale, which came into operation in June 1940 were: cheese reduced from 1 oz. to ½ oz.; herrings reduced from 4/7 oz. to nil; tea reduced from ¾ z. to ½ oz.; jam increased from 1 oz. to 2 oz.
