First documented detection of Vibrio paracholerae in a Costa Rican foodborne outbreak. Genomic analysis confirmed species identity, revealing limitations of conventional PCR and MALDI methods. Findings underscore the need for genomic surveillance to accurately characterize emerging enteropathogens and support public health systems.
