Abstract
Clostridium perfringens has been implicated as the etiological agent in many food poisoning outbreaks. It is a Gram-positive anaerobic spore-forming bacilus. Spores of C. perfringens are widely distributed in soil, sewage, aquatic environments, animal and human intestine, and their presence is usually indicative of sewage contamination. The distribution of C. perfringens in water, sediment and fish/shellfish from brackish water and freshwater environments was investigated. Water, sediment and fish/shellfish samples collected from various locations in three districts of Kerala were screened for the presence of C. perfringens. The study revealed that incidence of C. perfringens was high in sediment samples compared to water samples. In farm sediment samples, occurence of C. perfringens was high (30%), and 22% of the fish/shellfish samples also harboured C. perfringens.
