Why is Bt corn not toxic to humans?
Bacillus thuringiensis (Bt) is a soil bacterium that produces insecticidal toxins. Genes from Bt can be inserted into crop plants to make them capable of producing an insecticidal toxin and therefore resistant to certain pests. There are no known adverse human health effects associated with Bt corn.
