M. Ashenafi, BACTERIOLOGICAL PROFILE AND HOLDING TEMPERATURES OF READY-TO-SERVE FOOD ITEMS IN AN OPEN MARKET IN AWASSA, ETHIOPIA, Tropical and geographical medicine, 47(6), 1995, pp. 244-247
Various types of ready-to-serve food items purchased at the Awassa ope
n market were evaluated for their bacteriological profile and holding
temperatures, The food items included roasted offals, fish soup, cooke
d and sauced macaroni and spaghetti, and shire sauce, Spaghetti and ma
caroni were held at ambient temperatures (20-30 degrees C) and had hig
h aerobic mesophilic count (>10(6) cfu/g) and Enterobacteriaceae count
(>10(5) cfu/g). They also yielded Shigella and Staphylococcus spp. Mo
st of the other food items were held at higher temperatures (>40 degre
es C) and the aerobic mesophilic count in most cases was relatively lo
wer (<10(5) cfu/g), Several bacterial genera were isolated and Microco
ccus and Bacillus spp dominated the aerobic microflora, The unhygienic
conditions of the food service environment, possibility of cross cont
amination from utensils and keeping food items at ambient temperatures
for several hours were considered to be critical points.
