Abstract
This work was carried out to determine the incidence ofCampylobacter jejuniin selected food products in Imo state, Nigeria. Unprocessed Chicken meat, Beef and processed salad vegetables (diced Carrots and cabbage) were assessed for the incidence ofCampylobacter jejuni. 600 samples were collected between August, 2017-December, 2017 from selected local Markets. TheCampylobacter jejuniwas characterized using relevant biochemical test, growth characteristics and antimicrobial susceptibility and the results were read off using ABIS online showing 99% similarity with 65% accuracy. Results show that chicken samples isolated from Ihiagwa and relief markets were positive toCampylobacter jejuniwith a 96% and 95% incidence respectively. More beef samples from Relief market were positive compared to those from Ihiagwa market with 56% and 43% incidence respectively. On the other hand higher incidence was reported for the salad vegetables from Relief market than those from Ihiagwa market with values of 22% and 16% respectively. Also most samples from Relief Market had higher microbial load than samples from Ihiagwa market. This work stresses the need for routine checks on meat sold in markets and also recommends proper processing of meat and vegetable samples before consumption.
Highlights
Food safety issues, portability and food availability are issues of concern globally [1]
Chicken meat and diced vegetable samples were obtained from two markets within Owerri zone which include Ihiagwa Market and Relief market. 100 samples each were collected from each location making a total of 600 samples
Results shows that the characterized colonies were 99% related to the target isolate (Campylobacter jejuni) with about 65% accuracy
Summary
Portability and food availability are issues of concern globally [1]. Routine check of food products for microbial quality is highly required. Campylobacter jejuni, the causative organism of a diarrheal disease often referred to as Campylobacteriosis, is a food borne zoonotic pathogen that has received global attention recently [1,2,3]. As a Zoonotic pathogen of global attention, infection in human arises as a result of consuming food substances which have been in contact with a reservoir of the pathogen or during handling of Poultry meats, offal or products as well as their exudates or faeces. Antimicrobial therapy is usually not required in some cases of Campylobacteriosis due to its self-limiting nature but in invasive cases of the disease and some cases of septicemia that is observed in immunocompromised
