Six thousand eight hundred and two Salmonella strains from 500 outbreaks and isolated cases were studied. The strains originated from the United States, the Caribbean Islands, Venezuela and Colombia. The distribution of the Salmonella types was discussed. The source of infection could be traced in 79 outbreaks to cases of disease, human carriers, fowl, pork, eggs, water and rodents contaminating food in storage. Examination of food samples collected in Illinois and in Puerto Rico showed a higher number of samples infected in the Caribbean. Food inspection lessens the danger of salmonellosis.
