Salmonellosis is one of the most common and widely distributed food-borne diseases. It constitutes a major public health burden and represents a significant cost in many countries. Salmonella are known for its wide range host and can cause clinical diseases in some hosts while in others, can be asymptomatic. Poultry and eggs are considered as major sources for different pathogenic Salmonella serotypes. Eggs produced locally under the small scale layer farm may present a hazard to consumers which may increase the spread of Salmonella in the environment. To investigate the occurrence of Salmonella, a total of 72 samples were taken from 6 poultry farm in some selected areas of Bangladesh. Sampling program was executed between October and December, 2013 and samples were tested using standard laboratory methods. Data was collected through direct interview and structured questionnaire. Our study shows that, true prevalence of Salmonella in egg shell and egg contents were 0.093% and 0.068% respectively. The highest apparent prevalence in Udayan poultry farm (50%) and lowest in Liza poultry farm (16.67%). The average frequency of egg shell contamination is positively correlated with re-use of egg tray without disinfection. To the best of our knowledge, this is the first investigation on Salmonella spp. in selected local egg production farms in Chittagong. Further detail study is highly recommended.

“…Ultimately, increases in bacterial antimicrobial resistance pose a considerable threat to public health, especially for vulnerable populations including young children, the elderly, and immunocompromised individuals [6]. Concentrated animal feeding operations (CAFOs) in agricultural practices have evolved to accommodate food consumption rates with increased agricultural output at the risk of introducing antimicrobial-resistant pathogens into the environment.…”

Introduction: The presence of antimicrobial-resistant Salmonella in poultry and poultry products, including eggs, is a global public health concern. This study aimed to estimate the levels and patterns of antimicrobial resistance of Salmonella from chicken eggs and assess consumers' raw egg consumption and farmers' handling practices. Methodology: A total of 300 egg samples were collected from Haramaya open market (n = 150) and Haramaya University poultry farm (n = 150) in Ethiopia. Questionnaires were administered to egg sellers and buyers. A sterile cotton swab was used to sample the surface of eggs. The shells were sterilized and the egg content sampled. Isolation was done using the conventional methods for the detection of Salmonella, following the standard guidelines from ISO 6579. Sensitivity to 12 selected antibiotics was tested following the procedure of the Clinical and Laboratory Standards Institute. Results: A level of 5.3% was observed among eggs shells from the open market and 0% among egg shells from the poultry farm, for an overall level of 2.7%. There was a significant difference (p = 0.004) between the prevalence of Salmonella spp. in sample site and sample type. Of the antimicrobials tested, Salmonella isolates were all resistant to erythromycin and clindamycin. Isolates were sensitive to ciprofloxacin (100%) and chloramphenicol (87.5%). All isolates were resistant to multiple antibiotics. One-third of the consumers were found to have eaten raw eggs for perceived medicinal values. Conclusion: To minimize the potential contamination of eggs by pathogens, the eggs should be properly handled, transported, and stored.

“…This is of great concern because majority infections with MDR Salmonella are acquired through the consumption of contaminated foods of animal origin such as swines and chicken eggs mentioned that cephalosporin and fluoroquinone-resistant strains of S. Choleraesuis have been identified in swines in Taiwan and Thailand. Apart from that, antibiogram testing by [95] revealed Salmonella isolates from chicken eggs in marketing channels and poultry farms in North India were resistant to bacitracin, colistin and polymyxin-B.…”

This article has reviewed researches that obtained from peer-reviewed literatures on Salmonellosis and Shigellosis in different parts of Ethiopia. The prevalence of Salmonella and Shigella, the causative agent for Salmonellosis and Shigellosis, respectively, their antibiogram and growth potential were the main objectives of this review. Foodborne diseases related to unhygienic food handling practices remain a major public health problem across the globe. The problem is severe in developing countries due to limitations in securing optimal hygienic food handling practices. Data shows that an estimated 70% of cases of diarrheal diseases are associated with the consumption of foods contaminated with pathogenic microorganisms. Among these microorganisms Salmonella and Shigella are the major ones. In most studies of Antibiograms tests, Salmonella and Shigella spp. showed high resistance to the commonly used antibiotics which indicate serious problems in antimicrobial therapy globally, especially in developing countries. In challenge studies, Salmonella and Shigella spp. reached the infective dose within 4 to 24 hours of inoculation, respectively in various food samples. In this review, it is noted that these potentially pathogens are still public health problems. Therefore, there needs health education, frequent monitory and evaluation system of microbiological and antimicrobial surveillance so as to plan intervention strategies for at risk population in the area of water sanitation and hygienic food handling practice to minimize the burden posed by the diseases Salmonellosis and Shigellosis. Keywords: Antibiograms; Diarrheal diseases; Ethiopia; Foodborne diseases; Growth potential; Salmonellosis; Shigellosis. IntroductionAs far back as the documentation of human history goes, consumption of food unsafe for health and its consequences have been one of man's major health problems. They still remain to be a major public health concern globally. Food-borne diseases are known to be responsible for a large proportion of adult illnesses and deaths; more importantly, as sources of acute diarrheal diseases, they are known to claim the lives of overwhelming numbers of children every day [1].Globally, Food borne diseases remain a major public health problem. The problem is severe in developing countries due to difficulties in securing optimal hygienic food handling practices. Evidently, in developing countries, up to an estimated 70% of cases of diarrheal disease are associated with the consumption of contaminated food [1]. Transmission of enteropathogenic bacteria is affected directly or indirectly through objects contaminated with faeces. These include food and water indicating the importance of faecal-oral humanto-human transmission [2].Furthermore, acute infective diarrhoea and gastroenteritis are major causes of ill health and premature deaths in developing world due, in large part, to the lack of safe drinking water, sanitation and hygiene, as well as poorer overall health and nutritional status. According to the ...
