SUMMARY There are two reasons for the bacteriological examination of water supplies and foods; first to determine whether the commodity is safe to consume, i.e. that pathogenic organisms are absent; second, to determine whether the commodity is clean, i.e. that the level of nonpathogenic organisms is such that the commodity will suffer no significant deterioration in quality during normal conditions of storage and transport between preparation and delivery to the consumer. In the examination of water supplies and of shellfish growing in polluted waters, both the safety and the cleanliness of the product are assessed by a single examination for the presence of the normal inhabitants of the intestinal tract of man and animals. In the examination of foods only the cleanliness of the product is assessed by an examination for the presence of normal intestinal inhabitants. The safety of foods can be assessed only by examination for the presence of pathogenic organisms.
