Introduction: This study was conducted to evaluate the quantity of medium filth (najs
mutawassitah) and the growth rate of faecal borne bacteria in self prepared fried rice
toward the standardization of ‘halalan toyyibah’ food. Methods: The samples of fried rice
were cooked with the application of hygienic practices. A specific quantity of human
stools were then purposely inoculated into the samples. The growth curves of the bacteria
were determined using NanoDrop 1000 UV-VIS Spectrophotometer at 630nm where the
initial and end of lag times for each of the bacterial growth were determined. Results:
The results showed that if the contamination of human stools in the food is in small
quantity (1-2 drops), it may have no health risk at all (within lag time). If the human stools
are in higher volume (more than 2 drops, or about 1 ml) then it may start to contaminate
the food and could then lead to health risks. If foods are contaminated with small amounts
(about 0.1 ml) of human stools and left at ambient temperature (about 37o
C) for about 4
hours, the same thing will happen. Conclusions: If the level of health risk is translated
according to Shariah law, foods which are contaminated with higher amount (more than 2
drops, or about 1 ml) of human stools or contaminated with small amounts (1-2 drops) of
human stools, but are left (about 4 hours) at ambient temperature can be considered as
shubhah/makhrooh to be eaten. |
