Willie Vogt BASF is working with customers to replace seed although varieties do not pose allergic risk to humans or toxic risk to animals. BASF has detected the presence of two genetically engineered traits in canola seed samples taken from BASF’s hybrid seed production fields in the United States. These events are designed to increase Omega-3 fatty acid content in the seed oil for use in aquaculture and human foods. While the detected events, LBFLFK or BASF-Cargill Omega-3 and NS-B50027-4, owned by Nuseed, are approved for cultivation in the United States, they have not yet received approval in key export countries.
