Troops were warned against taking any of the cool drinks supplied by the Egyptians. The native beer was also not to be trusted, page 48 and even the beer and cordials allowed in the camp were often found to be quite unsatisfactory. Troops were also advised not to drink water apart from the camp supply. If there was any question of its purity, water was to be boiled, and tea was strongly recommended as the routine drink. Fresh milk had always to be boiled. Only those cordials from sources approved by the Army were allowed. Ice was considered to be almost invariably contaminated during transport and its use in drinks was prohibited.
