Public health officials and the media have been spreading the word about which peanut products are on the salmonella recall list, but misinformation still abounds, a recent Harvard School of Public Health survey found.

In one week, the Indiana State Department of Health's toll-free line handled more than 2,000 calls asking about products that have been recalled as part of the national salmonella outbreak.

Harvard's survey found that although 93 percent of Americans knew about the recall, fewer than half knew it included snack bars, baked goods and dry-roasted peanuts. One-quarter of those surveyed mistakenly thought major-brand peanut butter jars were on the list.

Of most concern, however, was the public's lack of knowledge of what not to eat, especially given that 90 percent said they ate peanut products, said Robert Blendon, a professor of health policy and political analysis who conducted the study.
