1507 maize meets all the latest EU safety evaluations -- Bt has a long history of safe use for more than 40 years, including by organic growers -- The Cry1F and PAT proteins expressed in 1507 maize are not toxic or allergenic to humans and animals -- The Cry1F protein confers resistance to target insect pests and reduces the need for spraying -- 1507 maize contains no antibiotic resistance marker gene (Instead, the PAT protein conferring tolerance to glufosinate-ammonium herbicide was used as the selectable genetic marker.
In the experiment that produced ANDi, some 224 eggs were modified using a viral vector to carry the marker gene (called GFP because it expresses a green fluorescent jellyfish protein) into the egg.
