One serious threat to public health in both developed and developing countries is the microbial contamination of food. This problem poses a great challenge and consequently has economic implications. Causes of microbial contamination are diverse and these may be natural, environmental, or technological. The microbiological quality of most ready-to-eat foods is of great significance to human health because they require minimal or no processing  when consumed.The  aim  of  this  research  was  to  investigate  the microbiological quality of some ready-to-eat mixed vegetable salad foods, ingredients as well as the wash water samples of an urban restaurant located in Accra, Ghana. A total of thirty (30) samples categorized into mixed vegetable salads, foods and water obtained from an urban restaurant in the national capital of Ghana, Accra. They were analyzed at the microbiology laboratory and food microbiology laboratories of School of Allied Health  Sciences(UHAS)and Council  for  Scientific  and Industrial  Research-Food Research Institute (CSIR-FRI), Ghana,respectively. Standard microbiological methods that are per International Organization for Standardization(ISO) Methods and Nordic Committee on Food Analysis Methods (NMKL) were used in determining the presence and levels of bacteria and fungi.Data obtained were transformed from standard to logarithmic forms and reported as mean+standard deviations. The aerobic plate count samples ranged from 0-4.73 log 10CFU/g. E-coli counts also ranged between 0-2.53 log 10CFU,  while Bacillus  cereus counts  were  very  low at0-&lt;10log 10CFU/g. Clostridium perfringens and Staphylococcus aureus counts were also very low ranging from0-1.0log10CFU/g.Enterobacteriaceae counts also ranged from 0-1.90 log10CFU/g. Molds and yeasts counts were generally low and ranged from 0-2.48 log 10CFU/g and 0-1.0 log10CFU/g,respectively. None of the samples tested contained Listeria monocytogenes and Salmonella spp. Fungal microbial loads were minimal given the quantities, and were deleterious to the health of consumers. The study revealed that the bacterial loads on mixed vegetable salads, ingredients and water samples used and served by an urban restaurant in Accra were within safe limits according to American Public Health Association (APHA) and International Commission for Microbiological Specifications  for  Foods  (ICMSF)  guidelines and,therefore,good for  human consumption.
