Disadvantages of GM Foods

Many people are concerned that insects will become resistant to B.t. or other crops that have been genetically-modified to produce their own pesticides.

Many children in the US and Europe have developed life-threatening allergies to peanuts and other foods. There is a possibility that introducing a gene into a plant may create a new allergen or cause an allergic reaction in some people.

There is a growing concern that introducing foreign genes into food plants may have an unexpected and negative impact on human health.

Bringing a GM food onto the market is a lengthy and costly process.

Another concern is that crop plants engineered for herbicide tolerance and weeds will cross-breed, which means the weeds will become tolerant to herbicides.
