Greenpeace volunteers have taken to the streets to stage individual protests across Australia against the use of genetically modified (GM) soy in chicken and turkey feed.

Greenpeace says they have tested the chicken feed used by Inghams and found that 70 per cent of the soy content is made from genetically modified soy beans.

Spokeswoman Tina Meckel says the organisation has spent the day letting the general public know that they could be eating genetically modified turkey this Christmas.

"People generally didn't know about this because products from animals fed GM don't have to be labelled so they were quite surprised," she said.

"Most of them were shocked and very disappointed that they are getting something in their food that they don't know about and that they really don't want."
