Salmonella surveillance in Guam.

A high incidence of human Salmonella infections (66/100,000 population for 1978) is reported for the island of Guam in Micronesia. S. waycross, a relatively rare serotype in other areas of the world and first isolated on Guam in 1974, accounted for 39% of all serotyped isolates from human cases in 1978. The possibility of this organism being introduced in imported products is discussed.
