ZIMBABWE will not allow the production of Genetically Modified Organisms even if they could help ensure food sufficiency, agriculture mechanisation minister, Dr Joseph Made has insisted. Made said the government would, instead, concentrate on making available fertilizer, seeds, irrigation and other essential farm inputs to boost food production rather than use cheaper but unsustainable means which have a detrimental impact on the environment. “Scientific research shows that GMOs contain toxic substances, are less nutritious than non-GMOs and have negative effects on humans and the environment,” he said here Thursday.
