KANSAS CITY, Mo. -- Some Kansas City restaurants got a visit from health officials Wednesday morning to warn them about the dangers of a nationwide salmonella outbreak.

The Kansas City Health Department sent out inspectors to help restaurateurs decipher the long list of recalled peanut butter products.

They were armed with an eight-page list of things that could be contaminated.

Health leaders said there hadn't been any cases in Kansas City of anyone getting sick, and they want to keep it that way by taking extra steps.

"With the 2007 outbreak, it was all just one brand and one set of lot numbers that we could pull off, with this, ... it went out to so many different food manufacturers, and was incorporated into so many of their products," said Jeff Hershberger, a spokesman.

Officials are were calling schools, hospitals and nursing homes because the elderly and children are more susceptible to getting sick.

Nearly 500 people have gotten sick nationwide. Six have died.
