Welcome to class of Role of Genetically-Modified (GM) Foods in Emerging Markets by Dr. Satyendra Singh University of Winnipeg Canada www.uwinnipeg.ca/~ssingh5 www.uwinnipeg.ca/~ssingh5
What are GM Foods? Crops created for human/animal consumption using the molecular biology technique to get desired traits such as:
Role of GM Foods in EMs Very important for developing countries/EMs –By 2050 pop. 9b food strategy for next 20 yrs –Need more food, as such hunger and starvation –3m deaths/year in Africa solely relating to hunger –3 options: aid/food, money/funds, provide GM foods GM foods: Rapid, accurate,↑ yield, ↓labor, ↑shelf-life
Advantages of GM Foods… Pest resistance –Crop loss due to insets financial loss to farmers –So, farmers use tons of pesticides/fertilizers annually –GM eliminates pesticides and thus ↓ cost of production Disease resistance –Viruses, fungi, bacteria plant diseases –GM crops resistance to these diseases Cold resistance –Frost can destroy sensitive seedlings –Antifreeze gene from cold fish tobacco and potatoes
Advantages of GM Foods Drought resistance –More population ↑ land for housing, ↓ land for farming –Land unsuited for plant cultivation Africa, dessert –GM crops grow in draughts or ↑ salt-content soil Nutrition –Single crop (rice) cannot give all the nutrition needed –Lack vitamin A blindness common in EMs –GM food: golden rice has Vitamin A (beta-carotene) –GM food: with enhanced iron is underway, Europe? Pharmaceuticals –Edible vaccines in tomatoes and potatoes –Easier to ship, store, administer than traditional injections
Criticism of GM Foods… Environmental hazards –Unintended harm to other organism Difficult to design toxin kills crop-damaging pests, not other insects –Reduced effectiveness of pesticides Develops resistance DDT –Gene transfer to non-target species Cross-breeding Transfer of herbicide resistance from crops to weeds The “superweeds” will then have herbicide tolerance as well Solution –Create buffer zone Enviro pigs they do not produce phosphates!
Criticism of GM Foods… Human health risks –Allergenicity –We already have allergies to peanuts and other foods… –Introducing gene may create more allergies –Unknown effects on human health –However, proposal to introduce a gene from Brazil nuts into Soyabeans was abandoned On the whole, with the exception of possible allergenicity, scientists believe that GM foods do not present a risk to human health!
Criticism of GM Foods Economic concerns –Lengthy and costly process –May be patented Monsanto, Novartis, Dow, DuPont hold patents for GM crops Make substantial profit by exporting it to EMs –Farmers from developing countries/EM cannot afford –More gap between rich and poor Other invention discouraged/stopped –Suicide gene technology Only one growing per season Next time would produce sterile seeds that do not germinate
Governments and GM Foods Europe: Anti-GM protests (Austria, France, Hungary) Japan: GM testing is mandatory. Customers for organic USA: FDA GM foods are substantially equivalent to natural food, so not subject to FDA regulations –GRAS Generally Recognized As Safe India: No policy yet for GM ↓ poverty Brazil: Some states have banned GM crops –↑Smuggle to compete with grain-exporting countries Africa: EU opposes the use of GM in Africa –S. Africa, Sudan, Zimbabwe have GM laws; Kenya Act 2009 Argentina : Indifferent New Zealand: NO GM Foods grown here!
GM Food Labeling No need to label same wrt to nutrition Europe and Japan Mandatory –1% contamination of unmodified products with GM foods –Consumers have the right the know the information –Let consumers decide but no choice –Reduced sales, so processors do not sell GM foods –EU has disguised policy of protectionism Canada and US Voluntary –Mandatory for Non-GM foods –Let consumers decide more choices
