5. CONCLUSION
The research
found Salmonella serovars in two of the RTE food outlets outlet I and II. S. Weltevreden was isolated from RTE food outlet I, from utensils washing
water sample, tea towels and food preparation tables . S. Agona was isolated from outlet from tea towels and food preparation tables . Outlet III did not have Salmonella
serovars present. MPN counts for coliforms were comparable with the hygienic inspection results.
Again the outlets selling more than one type of food outlets and II had high coliform counts; these outlets had poorer hygiene and sanitation conditions. The space of the
outlets also was a factor contributing to the hygiene conditions in turn affecting coliform counts. Thus, generally, it is comparable that the poorer the hygiene conditions, the
higher the coliform counts. It can be also specifically noted that in outlet III there was low coliform
contamination 3.00 x 10 MPN100cm

in utensils washing water; importathis was same for fecal contamination in utensils washing water and hands of food handlers.
This signifying that means of hygiene and sanitation practices aligned with washing water and hands in the outlet are favorably good. Furthermore, it can be concluded that,
there was a relationship between hygiene conditions and coliform total and fecal coliforms occurrence.
Salmonella occurrence in this study was such that, the more coliform 8.24 x

counts resulted in presence of Salmonella in the samples. This was observed in the samples having Salmonella serovars utensils washing water, tea
towels, and food preparation tables especially tea towels which showed almost all the outlets having higher coliform counts produced Salmonella. Therefore, outlets I and II
had Salmonella whilst outlet III having negative Salmonella
6. RECOMMENDATION
It is recommended that RTE food outlets I and II should improve their hygiene and sanitation conditions through training and supervision by safety authorities. Also
future studies are recommended especially in the areas to observe the occurrence of pathogenic bacteria and coliforms before and after cleaning the sampled areas in this
research to see the importance of having better hygienic and sanitation conditions.
