A recent survey revealed that public awareness and understanding of genetically modified (GM) foods remains relatively low and consumers' opinions about GM foods are as divided now as they were five years ago. The survey also shows that while religious belief has some impact, it is not a key source of variation in public attitudes toward biotechnology and finds that animal cloning evinces much stronger opposition than does the modifications of plants. This is the fifth comprehensive survey of U.S. consumer attitudes about public sentiment about genetically modified food conducted by the Pew Initiative on Food and Biotechnology. Similar comprehensive surveys were previously conducted in January 2001, August 2003, September 2004, and October 2005.
