Excerpt from General Results of the Investigations Showing the Effect of Formaldehyde Upon Digestion and HealthIn this connection it seems not out of place to call attention to the fact that apart from the injurious effects of formaldehyde itself its use as a preservative would be especially inadvisable in milk or cream, because its addition in dilute solution prevents the growth of acid forming bacteria, but has no effect in retarding the action of many harmful organisms; in other words, the milk is prevented from bscom ing sour, and thus indicating its age, and the danger signal is thus removed while the other organisms which are capable of producing disease continue to multiply in the milk with practically the same degree of.rapidity as if the formaldehyde were not present.Attention is again called to the proper and legitimate signification of the term injurious to health, when used in this connection. This phrase does not signify, that. A food which has an injurious sub stance added to it must in every instance produce notably injurious effects upon the consumer immediately; The question can only be logically and fairly studied by considering the continued or cumu lative effects, nor are these necessarily of such a character as to result in objective symptoms. Insidious efi'ects which. Are produced on the cells of the organs or on their histological structure are no less important; in fact, they are more important. These are the injuries which at first escape detection and may go to irremediable lengths before any outward symptoms of their existence are manifested.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
