Federal health officials said the salmonella recall now involves about 31 million pounds of peanut butter and peanut paste.

That's a whole lot of peanut butter.

But consider this: The nonprofit National Peanut Board said Americans eat 700 million pounds of the gooey treat every year.

Peanut Corp. of America -- the company that made the recalled products -- isn't an industry giant. But its peanut paste is used by others to make dozens of goodies, from energy bars, to cakes, to dog biscuits. And the recall list keeps getting longer.

It's making the food industry nervous, although no major national brands of peanut butter are affected. Even the Girl Scouts are reassuring customers Peanut Corp. is not their supplier.

More than 480 people have been sickened in the outbreak, which has contributed to at least six deaths.

Troops Urged To Dump PB Snacks In Care Parcels

The salmonella-and-peanuts investigation has the Defense Department urging troops to dump any peanut butter products, such as crackers or candy, sent to them in care packages.

"Based on my knowledge of the nonprofit groups that send care packages, I'm sure they will be vigilant and avoid shipping items that are being recalled," a Defense Department community relations spokeswoman told the American Forces Press Service.

"As an extra precaution, I would encourage service members to discard any peanut butter products that may have been shipped," she said.

Officials from the Centers for Disease Control and Prevention suggest that products produced since July 1 be avoided.
