Abstract
Outbreaks of Salmonella enterica serotype Enteritidis infections associated with eggs occurred in French Polynesia during 2008–2013. Molecular analysis of isolates by using clustered regularly interspaced short palindromic repeat polymorphisms and multilocus variable-number tandem-repeat analysis was performed. This subtyping made defining the epidemic strain, finding the source, and decontaminating affected poultry flocks possible.

Given that the poultry sector has been importing eggs and laying hens from North America for decades, that the A14-B21 clustered regularly interspaced short palindromic repeats (CRISPR) profile is prevalent in Salmonella Enteritidis genomes from North America, and that a A14-B21 Salmonella Enteritidis strain has recently been isolated from imported poultry from the United States since the implementation of control on imported poultry products and animals, it is likely that the epidemic Salmonella Enteritidis strain that was circulating in French Polynesia was imported from North America before 2008
When analyzed by classical subtyping methods, the Salmonella Enteritidis strains from French Polynesia displayed a very common and global profile, JEGX01.0004 pulsed-field gel electrophoresis (PFGE) type, PT8, and pansusceptibility to antimicrobial agents
