Genitically Modified Food (GMF)By: Wan Izzatie Wan Abdul Aziz

Definition

are foods derived from genetically modified organisms (GMOs)

changes introduced into their DNA by genetic engineering techniques

 inserted genes can come from species within the same kingdom (plant to plant) or between kingdoms (bacteria to plant)

Techniques: include selective breeding; plant breeding, and animal breeding, resistance to certain pests, diseases or

environmental conditions, or the production of a certain nutrient or pharmaceutical agent.

History

First commercial GMF -  Flavr Savr delayed ripening tomato(CGN-89564-2)

By: Calgene company production ceased in 1997

Flavr Savr

Slow ripening Prevent from softening Retain colour and flavor Resist to rotting (added antisense

gene)

GM Foods

Plums genetically engineered for resistance to plum pox

Transgenic carrots have been used to produce the drug Taliglucerase alfa which is used to treat Gaucher's disease

Roundup Ready soybean Six-pack rainbow fish  papaya has been genetically modified

to resist the ringspot virus

Effects on human’s health Recorded death from GMF:

genetically modified version of the food supplement L-tryptophan creating a debilitating ailment known as  Eosinophilia myalgia syndrome (EMS)

POTATOES - genetically-modified potatoes expressing cod genes were allergenic. 

PEAS - it was discovered that they caused allergic lung damage

Increase risk of cancer Birth defects Gene mixing- give supervirus Increased food allergies Shorter life span Interior toxins Lowered nutrition

How about u?
