30 confirmed cases of Salmonella are under investigation in Boise, ID, according to local news station KTVB. The Idaho Central District Health Department (CDHD) is looking into the potential that the outbreak originated from the Boise Co-op. A department spokeswoman noted that, in addition to interviewing those who became ill, health officials had taken multiple food samples for testing and were waiting on test results to determine whether the same strain of Salmonella had caused the illnesses. In a written statement released Saturday, the Boise Co-op said that the health department had done inspections over a two-day period and found no health code violations at the time. “The investigation is ongoing and we are taking it very seriously,” the statement read. “We are working closely with the CDHD to ensure they have all the information they need. These incidents appear to be related to food consumed between June 1 and June 7, 2015.” The first illness was reported on June 9. The health department is urging anyone in the area who has been experiencing symptoms such as diarrhea, vomiting and nausea to consult with a healthcare provider. In April, a Vietnamese restaurant in Boise was temporarily shut down after sickening at least five people with Salmonella.
