Katie Wagner of the Packet wrote a few moments ago “Salmonella infection count at university now at 28.” According to Ms. Wagner:

Since April 29, when the university learned of the first of the cases, a total of 20 students and eight staff members have been infected, university spokeswoman Cass Cliatt said. The latest date of onset of symptoms for the confirmed cases is May 2, which was before Princeton took its intervention measures to close the Mexican and salad food stations and remove some food foods at its largest dining facility on campus — the Frist Campus Center — Ms. Cliatt said. “No source determined, though state health officials say the cases are ‘associated’ with the Frist venue,” Ms. Cliatt said. “The investigators continue to work around the clock analyzing data from people who did and did not get sick.”
