Dr Ehtisham Ahmad, Chief medical officer at Aligarh’s J N Medical College said that rat poison is dangerous for human beings only when it is mixed with anticoagulant ( a substance that prevents or reduces coagulation of blood). This poison in the water would have made the students sick, however, the effect also depends on the quantity of the rat poison added, said Dr Ahmad.
