The outbreak of Salmonella infections that may be linked to pork products has grown to 90 cases in several counties around the state. The ongoing outbreak is under investigation by state, local, and federal public health agencies.
With the increase in cases, state health officials have asked the federal Centers for Disease Control and Prevention (CDC) to send a special team to help with the investigation. This team of “disease detectives” will arrive in Washington next week.
Disease investigators are searching for possible exposure sources from farm to table. An apparent link to pork consumption or contamination from raw pork is the strongest lead, though no specific source has yet been found. The likely source of exposure for some of the ill people appears to have been whole roasted pigs, cooked and served at private events.
The cases, many of which are in King County, appear to have been caused by the same rare strain of Salmonella bacteria, health officials said. The outbreak is linked to Salmonella I, 4, 5, 12:i:-, a germ that has been emerging nationally but has never before been seen in Washington state.
