The Australian Army Medical Corps in Egypt by Barrett and Deane

Excerpt:
The voyage itself does not call for lengthy comment. The ship was unsuitable for the purpose for which she had been chartered. She was small, overcrowded, and not as clean or sanitary as she might have been. Her speed seemed to decrease, and was scarcely respectable at any time; there were apparently breakdowns of the engines; and the food supplied to the officers and nurses was not infrequently inferior in quality and in preparation. In consequence an outbreak of ptomaine poisoning took place, and twenty-two officers and others were infected, two of them seriously.
The arrangements at the men's canteen had not been fully thought out, and in the Tropics it was not possible to obtain fruit of any description. Fresh or tinned fruits were not kept in stock. There was some tinned meat and fish, but the men could obtain nothing to drink except a mixture made from Colombo limes and water.
