The Joint Parliamentary Committee probing the presence of pesticides in soft drinks asked the Central Food Technological Research Institute (CFTRI), Mysore, and Central Food Laboratory (CFL), Kolkata, to explain their test methodology. The results from the two institutes were at variance with those of the Centre for Science and Environment (CSE). Officials of the two institutes told the JPC that they were not the same samples that were tested by CSE, sources said. Following the observation by the CSE that pesticide levels in soft drinks in India were alarmingly high, two sets of samples were sent to CFTRI and CFL for analysis. However, the two labs had stated in their report that the samples were not from the same batch, hence not comparable.
