Linking between contamination of environmental water and Salmonella foodborne illness: A Review

Abstract

Salmonella is one of the etiological agents of intestinal illness as well as typhoid and paratyphoid fever
throughout the world. While food is known to be a common vehicle for the transmission of typhoidal
Salmonella serovars, non-typhoidal Salmonella are mainly known as foodborne pathogens. But recent
studies found water as vehicle for transmission of Salmonella serovars. And several studies have showed
the role of contaminated water in Salmonella foodborne illness. So, this paper provides a brief review of
the last twenty years of peer reviewed publications on the prevalence of Salmonella in environmental water,
and relationship between contaminated water and Salmonella foodborne infections. Salmonella represent
zoonotic bacteria that are distributed throughout the world. Data relating to Salmonella prevalence in water
indicated a mixed human and animal origin of Salmonella contribution to water contamination. This study
has also emphasized on the role of these contaminated water in occurring Salmonella foodborne diseases
and its implication on global public health problem.
