Background Information¶

Salmonella enterica subsp. enterica serovar Poona (antigenic formula 1,13,22:z:1,6) is a serovar of the O:13 (G) serogroup.

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 carriedbla_CTX-M-15,qnrB1, and other antimicrobial resistance genes.

Animal Reservoir¶

Serovar Poona has been found in turtles, and has been associated with salmonellosis outbreaks in pet turtles.

Geographical Distribution¶

Serovar Poona has been reported worldwide.

Human/Animal Outbreaks¶

Several outbreaks have been associated with serovar Poona.

Year	Location	Associated source	Number of cases
2019	Europe: multi-country¹	Infant formula	32
2019	Finland	Watermelon	9
2015-2016	US-multistate	Pet turtles	70
2015-2016	US-multistate	Cucumbers from Mexico	907
2015	US-multistate	Pet turtles	25
2000-2002	US-multistate	Cantaloupe	155²

¹France, Belgium, and Luxembourg

²Three outbreaks of serovar Poona linked to cantaloupe occurred in 2000-2002. This is the total case number for all three outbreaks.

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
2020	Brazil	Germany	Black pepper	Herbs and spices

¹Both Salmonella Poona and Morehead were identified
