There have been at least 56 confirmed cases of Salmonella infections across eight counties in Washington State. Specific to Grays Harbor County, there has only been one confirmed case, and King County has had the most with 44 confirmed cases. Investigation has shown that whole roasted pigs served at private events could be a common exposure.
Salmonella is a type of bacteria that can be responsible for food poisoning. Symptoms can include fever, diarrhea, cramping and dehydration. Salmonella can also be responsible for Typhoid fever, which is divided into four stages: the first stage, the symptoms are more like a regular fever, the body temperature rises, and the subject experiences a slowed heart rate, headache and cough. In the second stage, the subject experiences high fever, and is often too tired to get up. Delerium can be present in this stage as well as rose spots all over the subject's body. The third stage can bring intestinal hemorrhaging, delirium and dehydration. Finally the fourth stage carries the symptoms of the third stage over until they begin to subside.
Precautions one can take against Salmonella would be proper food care and preparation as well as making sure that the food is cooked thoroughly. Washington State health officials have specifically advised against eating raw or undercooked pork.
