What Did AI and Beer Have to Do With a Salmonella Outbreak?

"From reading the report, it certainly looks like the Brown County Health Department did their due diligence in exploring all possible angles for how these people became ill. They found that four of the affected people did not buy food at the fair; of the affected people, four had also not used the portable restrooms there. Two of the people who later fell sick even brought their own hand sanitizer to the fair and used it."

"In analyzing the possible culprits, the health department then consulted artificial intelligence on the matter - specifically, ChatGPT. In the report published in the MMWR, author Katherine E. Houser notes that ChatGPT told investigators "that ice contamination is often an overlooked transmission vector" for salmonella."

"It's unclear how helpful the chatbot actually was in this case. Most of the details about salmonella spreading through ice are publicly available. And it raises the question of where a hallucinated response might have taken this particular line of inquiry."

A 2024 county fair in Brown County, Illinois resulted in seven to 13 attendees developing salmonella, with the common factor being consumption of beer stored in a cooler with ice. The Brown County Health Department conducted thorough investigation, eliminating other potential sources such as fair food, portable restrooms, and hand hygiene practices. The investigation consulted ChatGPT, which identified ice contamination as an often-overlooked salmonella transmission vector. However, questions arose about the necessity of AI involvement, as information about salmonella transmission through ice is publicly available, and concerns exist regarding potential AI hallucinations in outbreak investigations.
