The Utah Department of Health is investigating two additional cases of salmonella. Laboratory testing is under way to determine if they are linked to the nationwide outbreak. These individuals have a travel history outside of Utah during the incubation period.

Utah does have one case of salmonella Saintpaul that is linked to the nationwide outbreak. This individual reported eating tomatoes, but it is likely that this exposure occurred outside Utah.

We have no evidence that people eating tomatoes in Utah have gotten sick from salmonella, said Marilee Poulson, an epidemiologist with the UDOH. But we continue to monitor the situation for cases that could be linked to the outbreak.

Some but not all tomatoes have been implicated in the outbreak. Government officials are still working to determine the exact source and location of the affected tomatoes. For more information on which tomatoes are safe visit: www.fda.gov/oc/opacom/hottopics/tomatoes.html#retailers.

The major symptom of salmonella is diarrhea, which may be accompanied by abdominal cramping, vomiting, and fever. If you think you may have salmonella, you should see your doctor. Laboratory testing of stool is the only way to determine if you have salmonella or if your illness is connected with this outbreak.

Salmonella is not an unusual disease; public health in Utah typically receives reports on over 200 cases per year. Common sources of salmonella include undercooked poultry, raw or undercooked eggs, or contaminated produce. Be sure to thoroughly cook poultry and eggs, and wash produce before eating.

Another common way of acquiring salmonella is through contact with lizards, turtles, baby chickens and other animals. It is important to wash your hands or your child's hands thoroughly after handling or petting animals.
