Environmental groups alerted the public on Tuesday on the presence of genetically modified organisms in white corn, a staple in Visayas and Mindanao. Greenpeace campaigner Daniel Ocampo said that recently “contaminated” corn crops are incidental spawns of Bacillus thuringiensis corn, a variety known to contain GMOs, produced by processes supported by the Department of Agriculture. Bohol farmers reported the spread of GMOs in the soil where they grow white corn, and that such cross-pollination cannot be controlled, the group said.
