Camylobacter is the leading cause of foodborne bacterial gastroenteritis worldwide. Campylobacter spp. are ubiquitous in the intestines of almost all poultry and wild birds. Poultry products are important source of human Campylobacteriosis. The main aim of this study was to screen the chicken eggs for the presence of Campylobacter spp. from retail outlets in central Kerala viz., Ernakulum, Palakkad and Thrissur. A total of 180 chicken egg samples, comprising 90 samples each were collected during two seasons, monsoon and summer. All the samples were subjected to isolation and identification by conventional culture technique. The charcoal based selective media modified charcoal cefoperazone deoxycholate agar was used for the isolation of Campylobacter spp. The occurrence of Campylobacter spp. in chicken egg samples was high in Ernakulum (13.3 per cent) district followed by Palakkad and Thrissur districts with 6.7 per cent each during monsoon season. In summer, highest occurrence was noticed in Palakkad district (6.7 per cent) followed by Ernakulum and Thrissur districts with 3.3 per cent each. The occurrence of Campylobacter spp. showed no significant difference between monsoon (8.9 per cent) and summer (4.44 per cent). An overall 6.7 per cent samples were positive for Campylobacterspp. in central Kerala. All the isolates were hippurate hydrolysis positive depicting C. jejuni as a main contaminant. Contamination of eggs with Campylobacter spp. is a threat to handlers and consumers, and is a major public health issue. The study necessitates the importance of Good Hygienic practices to be followed in the egg production chain to combat the Campylobacteriosis.
Keywords: poultry, Campylobacter spp., hippurate hydrolysis.
