Question

Q: Do BT eggplants contain toxins that cause cancer and skin diseases to humans?

Answered By Amit Dhingra - Dec 16, 2014

A: Bt is a protein present in a commonly occurring soil bacterium called Bacillus thuringiensis. For it to be active against any other living organism, it needs two things. First, the target organism should have a complementary protein (usually called a receptor) that can bind Bt, and second, it should have a pH that is alkaline.   The human gut and skin lack receptors that can recognize and interact with Bt. Moreover, the human gut is acidic, thanks to all the hydrochloric acid that our stomachs produce naturally. Therefore, Bt gets the same treatment all other proteins get once it en [...]
