The idli or dosa ready available in
the market mix might contain bacteria. The presence of bacteria indicates fecal
contamination. According to a survey conducted by Concert (Centre for consumer
education, research, teaching, training and testing) among 20 local brands in
Tamil Nadu, 55% i.e. 11 of the locally available ready mixes are contaminated. This
bacterial contamination can lead to health hazards like vomiting, diarrhea and
This impurity can be attributed to the
possible poor hygienic practices while preparing the rice, urad dal and water
mixed batter which usually costs around Rs. 20 per kg. The tests were done
using Hydrogen Sulphide Spot Test Kits which turns the sample black if it
contains hydrogen sulphide containing bacteria (Salmonella). These kits were
issued by the Tamil Nadu Water Supply and Drainage Board.
Director of Concert, G.
Santhanarajan said, "What is unknown is whether these ingredients are of a
high standard, or if their handling is hygienic." However the authorities
refused to divulge the names of popular brands.
