In cases of slightest doubt about contamination of water, it must be boiled before use for drinking and cooking purposes. All foodstuffs must be kept covered and vegetables and fruits washed with a solution of potassium permanganate before consump-tion. Other precautions against this disease include avoiding all uncooked vegetables, thorough washing of hands by all who handle food, and the elimination of all contacts with the disease.
