he objective of this study is to count the number of viable bacteria and the number of
coliform bacteria on feeds and cooking utensils in Omuta City Zoo.
We wiped a cabbage, a carrot, a sweet potato, a horse mackerel, meat of horse, chicken
and a kidney of cattle as feeds and knives, chopping boards and scrub sponges as utensils
with sterile absorbent cotton swabs. Each swab was diluted with 10 ml sterile phosphate
buffered salts whose 1ml was used as a sample.
Regarding the feeds, both the number of viable bacteria and the number of coliform
bacteria on chicken were much more than the other feeds. It is necessary to pay attention
to avoid the contamination. The utensils compared favorably in number of bacteria with the
utensils at dining room used for human being.
