The Iowa Department of Public Health is seeing a sudden increase in salmonella cases.
There are now 26 reports in 19 counties. Polk, Webster and Cerro Gordo counties are reporting the most cases.
Authorities say this is a relatively uncommon strain of salmonella. Officials say salmonella is usually due to improper handling or preparing food but this strain is often associated with improper cooking of poultry or eggs.
Officials urge you to cook chicken to 165-degrees and make sure yolks are firm when putting eggs in salads.
