MADISON, Wis. -- As the recall of products containing peanut butter continues over concerns they might be contaminated with salmonella, Girl Scouts selling cookies are trying to get the word out that their cookies aren't part of the recall, WISC-TV reported.

Federal officials said the contaminated peanut butter has contributed to six deaths and sickened more than 480 people.

This week, the Food and Drug Administration has added more products to its recall list, including snacks and even some pet foods.

Girl Scouts in Madison are in the middle of their annual cookie sales. While experts say people should avoid peanut butter products until this problem passes, the Girl Scouts said their peanut butter products are problem-free.

"Most of the phone calls and the e-mails have said, 'We want to buy Girl Scout cookies. We're concerned about the peanut butter situation. Are they safe to buy?'" said Barbie Wiers, of the Girl Scouts, Black Hawk Council.

Wiers said buyers of Girl Scout cookies don't have to worry about salmonella contamination.

"Our baker is ABC Bakers, which is a subsidiary of Interbake Bakers. They voluntarily test all of their incoming peanut butter shipments, so we know they're in the clear there," Wiers said.

As people cut back on buying products with peanut butter, Girl Scouts said they hope people don't avoid their cookies.

Even though the salmonella threat has been traced to a single Peanut Corp. of America plant in Georgia, health officials are urging people to simply toss out any products in their home that contain peanut butter -- with the exception of plain, jarred peanut butter.
