Is BT Brinjal poisonous for our body?

By Shekhar Sahu on 07 February 2010 3:15 PM


The controversy of BT Brinjal in India is increasing day by day and the protest has taken media attention. Supreme Court of India has advised the company to test the B.T. Brinjal on the field, and it will only be approved after two years.   Let's explore the BT Brinjal here, and get what you want to know about BT Brinjal.

What actually is the BT Brinjal?

BT Brinjal is a result of modification in genes of Brinjal or Eggplant by use of genetic engineering of our booming biotechnology. The gene of one particular bacteria is inserted in the structure of gene of natural Brinjal so that the resultant hybrid brinjal can produce a new protein, which changes it's properties and makes it poisonous to kill all pests and insects.  The insects named SFB to destroy a huge amount of crops approximately Rs 1000 crore.

Why is it named BT?  What is BT?
 The bacteria, whose gene is used to make this change in the structure of Brinjal is Bacillus thuringiensis (BT), this is why the name BT Brinjal is derived.

Have you heard of BT Cotton?
Same as the BT Brinjal, BT Cotton was also produced by inserting the genes of the same BT Bacteria. Which Indian farmers have been cultivating for 8 years.

One thing to pay attention is Cotton is not an edible crop so this is not harmful to humans or any animal.
But, brinjal is a food which may have enough danger for the human body.

a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity

About Maharashtra Hybrid Seeds Company
The Company Mahyco is based in Maharashtra. The company researched BT crops in collaboration with an American company Monsanto. The trial began in the fields in 2006 after the six years of research.

How Does BT  Crop kill insects?
When insects suck the food from BT crops, the poison enters in their body and reaches the intestine. The neutralization of Base and Acid takes place which causes damage to their stomach killing insects. So, BT crops require no or less amount of insecticide, saving some money.

Why Protest BT Brinjal and Other BT Foods?
In Recent days Scientists, Peasant and NGOs started protesting the BT Brinjal to protect humans, animals, and the environment. Many organizations have headed to the Supreme Court of India to prohibit the cultivation of BT Brinjal and other BT Foods. Many state governments have already announced that they will not allow the cultivation of BT Brinjal. Since very adverse effects have been seen in BT Cotton.
Scientists have estimated that the use of BT Brinjal further can make insects resistant to insecticides or any antibiotic medicine. So any use of insecticides and pesticides won't work eventually.
BT Brinjals have been tested only on few mice in the labs, which is not enough to be approved for cultivation.
These Brinjals may affect the human body, and it's not safe to eat.
BT crops require a huge amount of water for the irrigation. We also know that irrigation is a big problem in India due to irregular monsoon.

BT Crops in Other Countries
Cultivation of BT crops is allowed in America, Brazil, Canada, Argentina, China, India, Paraguay and South Africa. However, it's prohibited in Thailand, Japan, Algeria, Shrilanka, Austria, Hungry, Germany, France, Spain and some more countries of Europe.

So, I think the property or the advantage by which BT Brinjal can become poisonous to killing insects, became it's the biggest disadvantage. There are various safe methods already available- by the hybridization of different pieces of bread of brinjals of the desired property, instead of making any harmful genetic changes.
Because we all love our lives, we should protest BT foods. I invite all bloggers to come and show the protest against BT Brinjal.

This was to give you some information about BT Brinjal. Do you have any other info, please share it here! What are your views about BT Brinjal and other BT crops?

Yes, BT is making a lot of news. I was not aware of the disadvantages. Good info.

This is the first time I heard about Bt Brinjal =)

Ah Shekhar.. It's been making the news, but i really never knew what they were talking about BT Brinjal. There are so many arguments for & against this topic.

But your article gave an indepth view.

Thanks for sharing.

Yes friend we should protest against this, luckily the central gov. takes a good decision.

I never heard about it. Thanks for notifying this issue. We have to talk about this. Going to show this information to my twitter followers. Thanks for this insightful article.

Still the BT brinjal concept is not very clear to me. Results are unknown.

In march 2010 MONSANTO admitted that pink boll worm of cotton has developed resistance to bollgard I. Simillarly, there are many chances of FSB developing resistance against BT brinjal.we should not allow this.

I do accept the resistance development of insect by the application of bt GMO but its obvious that any organism reacts to continous specific stress,either physical or biological stress even at gene level.which happens in application of most of the pesticide.

kindly give in detail about the physiological and biochemical hazards that you witness or expect on human.

when a technology can be developed at this end why dont you think it can be made so elite in future to harbour biosafety.

Reduction of inorganic pesticide and retention of soil fertility is acheived well by using bt wat is ur comment on usage of inorganic pesticides which remains on agro soil and their impact on humans relatively.

These are my personal views and i am no way related to MAHYCO or MONSANTO .any one intrested could answer for it especially the author.
