Asymptomatic typhoid carriers in Namakkal District, Tamilnadu.

ABSTRACT

A study was made on the sources and spread of Salmonella spp at Namakkal District, Tamilnadu, to ascertain positive carriers of the pathogen. Of the 150 samples collected from varied sources, food handlers significantly contributed to the spread of S. typhi, S. paratyphi A and B, the presence of which was ascertained by standard confirmatory tests. It is inferred that a periodic assay of Salmonella spp in food stuff and food handlers can help in the control of food borne disease.
