I plan to use a water barrel this year to collect rain water for our vegetable garden. I would like to treat the water with 'Dunk' tablets to prevent mosquito larva. Will the 'dunk' end up collecting in my veggies and make us sick.

Mosquito Dunks contain Bacillus thuringiensis israelensis (B.t.i.). B.t.i. is a bacterium toxic to Mosquito and black and psychodid fly larvae but harmless to other insects, people, pets, plants and the environment.
