Salmonella Outbreak Hits 42 States

A nationwide salmonella outbreak that has struck Ohio and 41 other states has put about one in five of its victims in the hospital, the U.S. Centers for Disease Control and Prevention said Thursday.

Nearly 400 people have become ill in the outbreak that might have killed one person. An elderly woman in Minnesota had the infection when she died, although it's not clear that salmonella was the cause, a health department spokesman there said.

The same type of salmonella bacteria has been lab-confirmed in 388 cases nationwide, said the CDC, which is leading the investigation but has not yet released the list of states or determined which foods may have caused people to become sick.

However, health officials in California, Georgia, Illinois, Michigan, Minnesota, North Dakota and Ohio have confirmed cases. Ohio and California reported the most, with 51 cases each.

Nationally, all the illnesses began between Sept. 3 and Dec. 29, but most of the people grew sick after Oct. 1.

Most people develop diarrhea, fever and abdominal cramps 12 to 72 hours after infection. The illness usually lasts four to seven days, and most people recover without treatment.

Officials say steps to protect against the illness include careful handling and preparation of raw meat, and frequent hand washing.

CDC officials say the cases in the outbreak have all been genetically fingerprinted as the Typhimurium type, which is among the most common forms of salmonella food poisoning. Of those cases for which CDC officials have medical treatment information, 18 percent were hospitalized.

A Connecticut congresswoman on Thursday said she was frustrated that health officials don't yet know how the bacteria have been spreading.

Not knowing what food is responsible means the U.S. Food and Drug Administration or the U.S. Department of Agriculture cannot help track the original source, said U.S. Rep. Rosa DeLauro, a Democrat who chairs the Agriculture-FDA appropriations subcommittee.

"Any delays in these critical investigations can sicken more people," DeLauro said in a statement.

But foodborne illness investigations can be very complicated, and it can take weeks or months for health officials to interview patients, find common links in what they ate, test suspected foods and come up with a clear-cut cause, said Michael Doyle, director of the University of Georgia's Center for Food Safety.

"There's a lot more to this than meets the eye," he said.

There are about 2,000 types of salmonella and about 40,000 cases are reported each year.

Of lab-confirmed cases, salmonella Typhimurium is the most common. The bacteria type is a year-round threat because it's found in meat and eggs, and not as subject to seasonal food supply variations as produce.

The current outbreak's bacteria are different from the salmonella Saintpaul bug that caused more than 1,400 illnesses last spring and summer. That was traced to vegetables from Mexico - jalapeno and serrano peppers and possibly certain types of tomatoes.
