The Food Standards Agency said worries about the economic downturn may have influenced people's priorities.
Main areas of concern were food poisoning, followed by food prices and also the amount of fat, salt and sugar in food.
The survey - the Quarterly public tracker - monitors changes in consumer attitudes to key food issues and the latest poll included interviews with over 2,000 people.
Some 60% of people were confident that enough was being done to protect health.
Concerns about GM food were down from a high of 20% of people in March 2004 to 7%.
And concern about pesticides was also at its lowest since tracking began in 2003, standing at 6%.
