To achieve this objective, Vi agglutination test was used to determine suggested typhoid carriers among food handlers then stool culture was performed on those with a positive Vi agglutination test. A questionnaire was designed to collect data from suggested typhoid carriers about hygienic practices during food handling and processing .
The collected data were reviewed and coded. Data were analyzed using SPSS versions 10.0 software for tabulation and statistical analysis.
The results showed that, ten percent of the examined food handlers were found positive typhoid carriers by Vi agglutination test, 48.5% of the suspected of typhoid carriers were found positive by stool culture, street vendors were more common among suspected typhoid carriers, all of whom had not received any health education about typhoid disease.
