Pickled herring which shows 8,000,000,000 bacteria per cc. in the liquor is certainly a questionable food article. In. Fig. 17.—Spores and hyphal fragments from decaying sweet pepper. "Dry rot" fungus.—{Howard, Yearbook U. S. Dept. of Agriculture, 1911.) this particular instance there was no objectionable odor noticeable, but the meat of the herring was somewhat soft. Smoked meats and fish should be examined for mold in addition to bacteria. This subject should receive immediate careful consideration on the part of food bacteriologists. Table I shows the number of organisms which may occur in some of the more common household food substances, fermented and unfermented. The figures are based upon direct counts. Table II is based upon the examination of factory products ob- tained in the open market. The numerical extremes in the micro-organisms given in Table II, are in direct ratio to the relative.
