Desserts served at healthcare facilities are being considered as the potential vehicle of illness. The desserts tested positive for low levels of Listeria monocytogenes, but have not been confirmed as the source of the outbreak.
In a new study, the UK Health Security Agency (UKHSA) evaluated the ability of artificial intelligence (AI) to detect foodborne illness outbreaks by analyzing online restaurant reviews. Although several challenges were identified that must be overcome before AI can be used routinely in epidemiological investigations, UKHSA believes the approach shows promise.
