Increasing health awareness has led to consumption of minimally processed foods in recent years. Minimally processed foods or other raw vegetables have become popular since it suits the present day necessity as need of elaborate preparations are not required .Fruits and vegetables carry microbial flora while passing from the farm to the table. The produce is exposed to potential microbial contamination at every step including cultivation, harvesting, transporting, packaging, storage and selling to the final consumers. Microbial spoilage and contaminating pathogens pose a serious problem in food safety. To minimize the risk of infection or intoxication associated, potential sources of contamination from the environment to the table should be identified and specific measures and interventions to prevent and/or minimize the risk of contamination should be considered and correctly implemented. This book provides an overview of the hazards associated with raw fruits and vegetables sold in the local markets, assessment of their microbial load and also evaluates the efficacy of the antimicrobial dips to minimize the associated microbial risks.

Consumers generally preferred fresh meat without refrigeration. In addition, considering the prevailing conditions at the retail outlets, contamination of the meat with microbes appears unavoidable. Hence, high bacterial load is expected in the meat sold at the retail outlets mainly due to lack of awareness towards hygienic conditions and poor infrastructure in the retail outlets. Hence, practices such as incorporation of antibiotics, chemical preservatives, antimicrobial compounds have been tried. Increasing incidences of some pathogens connected to food borne illness acquiring antibiotic resistance has been a worry. This perspective has put pressure on the food industry for progressive removal of chemical preservatives and adoption of natural alternatives to achieve the goal concerning microbial food safety. Herbal spices have been added to foods since ancient times, not only as flavouring agents, but also as folk medicine and food preservatives . Scarce information is available regarding their use as antimicrobial in meat industry. Hence, this study has been designed to high light the efficacy of some of the spices as antimicrobial in chicken meat system.

Pathological changes in the pulp and periradicular tissues are due to microorganisms and their byproducts. To achieve optimal healing of periradicular tissue and better prognosis of endodontic treatment, complete elimination of microorganisms, their byproducts, and infected tissue is the main goal of endodontic therapy. Mechanical instrumentation, antimicrobial irrigation, and intracanal medicaments are the commonly-employed methods to eliminate intracanal microbial load. However, mechanical instrumentation still remains the mainstay of root canal disinfection, as it provides a platform for the other two methods to act. The Continuous developments have been made in the nickel titanium rotary instruments since their introduction in endodontics almost two decades ago. ProTaper Next, K3XF, and Hyflex CM are recently-introduced rotary instruments made by thermomechanical treatment of NiTi alloys. The aim of the present study was to evaluate the effectiveness of these rotary NiTi systems and manual instruments, Hero Shaper and Nitiflex file, in reducing the Enterococcus faecalis population within root canals.

Periodontal or the diseases of gums is a very common polymicrobial problem these days affecting about 20-50% global population. It can be diagnosed by using BANA Test which is used to detect presence of periodontal pathogens thereby serving as a reliable marker of disease activity and also aiding in the monitoring of periodontal therapy. The conventional method of lowering the bacterial load in the periodontal pocket constitutes scaling and root planing, but to prevent recolonization the use of adjunctive methods has been advocated. The use of controlled release devices such as antibiotics enables maintenance of concentration of antimicrobial agent within the pocket. Chlorhexidine chip is used as an adjunct to scaling and root planing which meticulously treats periodontal disease and also prevents its recurrence.

Garlic (Alliums sativum) is the second most widely grown bulb after onion. Garlic is a well-known spice used in many Asian, African and European countries. Its significant chemical composition makes it medically important as garlic exhibited antimicrobial, antioxidant, anticarcenogenic, antidiabetic activities. Microbial spoilage of garlic proved the chief cause of postharvest losses every year. In the present study, Allium sativum was subjected to gamma irradiation to lessen the surface microbial load, hence prolonging the storage life.The garlic samples were irradiated at different doses of 0.25, 0.50 and 0.75kGy. Analysis of Organoleptic qualities and native microbial flora was carried out for both irradiated and non-irradiated garlic. The results revealed that gamma irradiation significantly reduced the microflora without causing harm to the organoleptic qualities of garlic at 0.5kGy and enhanced shelf life for 1 month as compare to non-irradiated garlic.

The aim of the research was to assess the microbiological load of chicken, minced meat and sausages sold on the informal markets in Harare, Zimbabwe. The analysis was based on determining the microbiological content of chicken, minced meat and sausage samples. Samples were collected from three different locations namely Mufakose, Machipisa and Mbare. . Ready-to-eat foods like meat pies are susceptible to microbial contamination and street vended foods has become a global health problem. To assess enteric bacteria contamination of meat pies made in homes and industry in Harare, between November 2017 and February 2018, a total of 48 pies were examined. The number of infections caused by antibiotic resistant bacteria is rising worldwide. Antibiotic resistant bacteria are found in most environments, especially in highly anthropized waters. Therefore, fish are potential disseminators of antimicrobial resistance (AMR). The above necessitated conducting a susceptibility test of bacteria isolated from 36 fish samples from informal market in Mufakose, Harare.

Bacterial isolates from commercial poultry feeds and from eggs, ovaries and oviducts of the broiler hens were used for characterization, bacterial load estimation, antibiogram profile analyses and identification using rDNA sequencing of the isolates. Presence of both Gram-positive and negative bacteria in the environment was indicated and bacterial loads in terms of total viable counts of the isolates were much higher in the reproductive organs than in the poultry feeds. Majority (33.33%) of the isolates was sensitive, 28.33% hypersensitive, 25.0% resistant and 13.33% intermediate against eight commonly used antibiotics. Three bacteria Bacillus cereus, Sphingobacterium daejeonens and Bacillus sp. were confirmed by 16S rDNA gene sequencing. Pathogenic bacterial contamination in the poultry feeds and reproductive organs of broiler chickens reinforces the need for proper hygiene in the processing of the poultry products for human consumption and a need for implementing measures that guard against the misuse of antimicrobial drugs in chicken feeds is therefore emphasized.
