The present study evaluated the effect of an edible coating of cassava starch and carvacrol in minimally processed pumpkin (MPP). The minimal inhibitory concentration (MIC) of carvacrol against Escherichia coli, Salmonella enterica serotype Typhimurium, Aeromonas hydrophila, and Staphylococcus aureus was determined. The edible coating that contained carvacrol at the MIC and 2 × MIC was applied to MPP, and effects were evaluated with regard to the survival of experimentally inoculated bacteria and autochthonous microflora in MPP. Total titratable acidity, pH, weight loss, and soluble solids over 7 days of storage under refrigeration was also analyzed. MIC of carvacrol was 312 μg/ml. Carvacrol at the MIC reduced the counts of E. coli and S. Typhimurium by approximately 5 log CFU/g. A. hydrophila was reduced by approximately 8 log CFU/g, and S. aureus was reduced by approximately 2 log CFU/g on the seventh day of storage. Carvacrol at the 2 × MIC completely inhibited all isolates on the first day of Storage. coliforms at 35°C and 45°C were not detected (< 3 MPN/g) with either treatment on all days of shelf life. The treatment groups exhibited a reduction of approximately 2 log CFU/g in psychrotrophic counts compared with controls on the last day of storage. Yeast and mold were not detected with either treatment over the same period. The addition of carvacrol did not affect total titratable acidity, pH, or soluble solids and improved weight loss. The edible coating of cassava starch with carvacrol may be an interesting approach to improve the safety and microbiological quality of MPP.

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 ...
