Background: Salmonella enterica subsp. enterica serovar Poona (antigenic formula 1,13,22:z:1,6) is a serovar of the O:13 (G) serogroup. This serovar has been isolated from found animal and produce sources.
NCBI PD link for serovar Poona: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Poona%22)
Genetic Characteristics: Serovar Poona has been found to be paraphyletic as serovar Bristol clusters within this serovar. A study of Salmonella genomes from human salmonellosis cases in Ghana found a strain of serovar Poona that carried blaCTX-M-15, qnrB1, and other antimicrobial resistance genes.
Animal ReservoirAnimal reservoir: Serovar Poona has been found in turtles, and has been associated with salmonellosis outbreaks in pet turtles.
Geographical distributionDistribution: Serovar Poona has been found in the United States,reported worldwide.
Human Outbreaks: Several outbreaks have been associated with serovar Poona.

Border Rejections: Numerous border rejections linked to Salmonella Poona have been reported. A majority of these border rejections were associated with black pepper and identified multiple Salmonella serovars including serovar Poona. A few examples are listed below:
Year | Exporting country | Importing country | Associated source | Product category |
| 2024 | Greenland | Germany | Frozen prawns | Crustaceans and products thereof |
| 2021 | Brazil | Germany | Black pepper1 | Herbs and spices |
