Iowa DPH Addresses Salmonella Outbreak Concerns

The Iowa Department of Public Health is collaborating with the Centers for Disease Control and public health officials in many states to investigate an ongoing multistate Salmonella outbreak.

One case in Iowa is being investigated as part of this cluster. The investigation has identified peanut butter as a potential source of infection, with Minnesota identifing a particular brand of peanut butter. The Iowa Dept. of Public Health (IDPH) wants Iowans to know that the peanut butter, associated with this outbreak, has not been distributed in Iowa.

Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps within12 to 72 hours after infection. The illness usually lasts four to seven days, and most persons recover without needing antibiotic treatment. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness. While hospitalization is rare, some persons can develop dehydration, so drinking plenty of fluids is important no matter what the cause of the diarrhea.


There is no vaccine to prevent salmonellosis, but the illness can be prevented:

* Always cook meat, especially poultry completely.

* Always cook eggs and food containing eggs completely.

* If making foods, such as eggnog, homemade ice cream or sauces, that include raw eggs, use pasteurized eggs. (These can be found at grocery stores, in the refrigerated section, as liquid or shell eggs.)

* Wash hands after touching animals, especially reptiles.
