A large <i>Cryptosporidium parvum</i> outbreak associated with a lamb-feeding event at a commercial farm in South Wales, March-April 2024: a retrospective cohort study.

ABSTRACT: Cryptosporidium parvum is a well-established cause of gastrointestinal illness in both humans and animals and often causes outbreaks at animal contact events, despite the availability of a code of practice that provides guidance on the safe management of these events.
