If there were any doubts about the genetically modified (GM) genes having already infiltrated into the food chain and environment, these should be dispelled with the recent discovery of widespread cultivation of unapproved GM seeds of crops such as brinjal and mustard, apart from cotton. In fact, in all probability, this might have happened before the advent of the first gene-manipulated crop, Bt-cotton, carrying the alien toxic gene derived from Bacillus thuringiensis (Bt) bacteria. The use of pest-killer Bt genes in agriculture, actually, began far ahead of the development of the genetically-engineered crops. Farmers have been using Bacillus thuringiensis as microbial pest control agent for decades all over the world. It has been a regular practice even in organic farming. This aside, being common soil-dwelling bacteria, Bt tends to be ingested by animals and human beings, even if inadvertently. Many imported food products, especially the processed foods, are also believed to contain GM ingredients without declaring it.
