Sixteen species of wildlife, comprising 1,925 specimens, were examined for Trichinella spiralis during the 1953-1960 period. Species found to be infected with parasites were rat, fox, mink, raccoon, and badger. Initially a high incidence of trichinae was found in the rat, fox, and mink, followed by a marked decline. There is some evidence of a cyclic occurrence in mink. The possible significance of wildlife reservoirs as vectors of trichiniaisis to grain-fed swine is discussed
