“…This result was not surprising, because of the exposure of these food samples to the atmosphere, coupled with storage temperature abuse while displaying the food items for sale to the public (Figure 1) might be responsible. This finding was consistence with several reports that street vended foods such as salads, macaroni, fufu, omotuo and red pepper usually had unacceptable levels of contamination [5,10,11]. We recorded in this study 76 bacterial isolates made up of six genera: Escherichia coli, S. Typhimurium, K. pneumoniae, Enterobacter spp., Serratia marcensens, Proteus spp.…”

Background and Aims: Food is of paramount importance to the sustenance of human health, on that basis this study was initiated with a view to determining bacterial agents associated with the vended foods and to investigating antibacterial resistance of the isolates. Methods: Twelve food samples from vendors were randomly collected from ten locations within Lagos environs. The food samples were analyzed bacteriologically by standard methods. The isolates were identified and subjected to antimicrobial susceptibility testing using standard procedures. Results: The total plate counts of bacteria recorded was between 2.98 × 10³ cfu/g in Jollofrice and 4.09 × 10⁴ cfu/g in Salad. Seventy-six bacterial isolates made up of six genera; Escherichia coli, Salmonella Typhimurium, Alcaligenes spp., Klebsiella pneumoniae, Enterobacter spp., Serratia marcensens and Proteus spp. were identified. Most of the bacterial isolates were moderately sensitive to cotrimoxazole, nalidixic acid, amoxicillin and nitrofurantion except in S. Typhimurium with less than 50% susceptibility. Also over 60% of the pathogens isolated were inhibited by ceftazidime, cefpodoxime, and levofloxacin antibiotics and most strains of E. coli, S. Typhimurium and K. pneumoniae were resistant to ofloxacin, ciprofloxacin and ceftriazone. Conclusion: The study revealed gross contamination of various vended foods. It also indicated that vended foods are potential ...

“…During these leisure activities, the risks of parasitic infections are higher (Hamit et al, 2008). Besides, this risk of contamination from street food had been highlighted by certain authors (Tidjani et al, 2006;Barro et al, 2007). Eight species of helminth were diagnosed during our investigation: four nematoda (A. lumbricoides, T. trichiura, hookworms and S. stercoralis), three cestoda (H. nana, T. solium and T. saginata) and a trematoda (S. mansoni).…”

Intestinal helminths constitute the primary cause of illnesses in pre and school age children in the less developed countries. Their importance has been disregarded for a long time because of their insidious and chronic nature. In order to assess the prevalence rate of intestinal helminths in Chadian children, a survey of intestinal worms was carried out from March 2010 to February 2011 in two ecological zones (Sahelian and Sudanian zones) in the Republic of Chad. 1002 children (541 boys and 461 girls) aged from 6 to 17 years were enrolled in our investigation. The coprological analysis carried out in this study included macroscopic examination, direct microscopic examination and two concentration techniques (the Kato method and the formalin-ether concentration technique). The results showed highly significant differences in the prevalence of intestinal helminths between the two ecological zones, the prevalence being generally higher in the Sudanian zone than in the Sahelian one. Among all the helminths identified in the two zones, Ascaris lumbricoides was the most common, followed by Hymenolepis nana. A regular deworming and improvement of the hygienic conditions in these zones could go a long way to prevent intestinal worm infections. The findings of the present study urgently call for an improvement in environmental hygiene, the sanitary education of the populations and the creation of a national program for the fight against intestinal helminths in Chad.

“…Disease causing microbes can get into fruits and vegetables through injured surfaces, such as wounds, scratches and ruptures that happen through growing to harvesting [3]. Contamination from raw processing tools and, processing conditions, inappropriate handling, and incidence of insanitary circumstances result considerably to the entrance of pathogens into fruit juices [3][4][5]. The survival of different of disease causing organisms in low pH atmospheres has been recognized at distance [6].…”

In general, fruit juices are considered as microbiologically safer than other food stuffs. Nevertheless, numerous infections of human epidemics have been related with the intake of fruit juices, which are contaminated. The objective of the current study was to assess the microbiological safety and quality of juices being served in Cafes/ Juice houses in Hossana town, Southern Ethiopia. Overall of 90 juice samples (30 samples each for avocado, mango and papaya), collected from six purposively selected cafes and/or juice houses in Hossana town, were examined. None of the juice makers had any experience to professional training on food hygiene and safety related to their job. Majority of fruits for juice making were brought from open market and stored in open ground in the cafes/juice houses. Additionally, the juices physico-chemical parameters, for instance pH and Titratable acidity were analyzed following standard protocols. The average aerobic mesophilic bacteria counts (CFU/ml) of avocado, mango and papaya were respectively 2.2 x 10 4 , 1.3 x 10 4 , and 7.4 x 10 3. The pH of juices were ranged from 4.05-5.79 and that of TA from 0.021-0.140 (g lactic acid/100 g sample). Mango juice was observed more acidic (pH= 4.05 ± 0.120) than papaya juice (pH= 5.33 ± 0.140) and avocado juice (5.79 ± 0.021). The main bacterial groups isolated from the fruit juices included Klebsella, Enterobacter, and S. aureus species. The microbial masses of the fruits juices examined were greater than the specifications set for fruit juices vended in the other areas of the world. To the writers' level of understanding, there is no requirement set for the acceptable level of microbes in fruit juices being served in the study area. Since main isolates were colonies of microorganisms, the reduced hygienic condition of the fruit juice makers and absence of information of using disinfection during processing, also the promising physico-chemical settings of the fruit juices could be contributed to the high microbial concentrations. Thus, great level of workers sanitation is necessity and the use of decontaminators would be better applied for the betterment the microbial quality, safety, and shelf life.
