Chickens refusing to eat the maize they had been fed has led to the discovery that their feed had been genetically modified to include a well-known weed and insect killer.
Strilli Oppenheimer was recently approached by Dawid Klopper, the head gardener at the family estate, Brenthurst, informing her that her indigenous African chickens were refusing to eat the mealies in the chicken feed bought from a large supplier. Concerned that the birds may be ingesting genetically modified maize, she instructed Klopper to have the maize tested.
The chickens' diet was immediately changed to include organic vegetables, Oppenheimer stopped consuming the home-grown eggs and the maize was sent to the Genetically-Modified-Organisms testing facility at the University of the Free State for analysis.
The results confirmed Oppenheimer's initial suspicion - the maize had been genetically engineered to produce proteins that are toxic to certain insects and weeds.
