67 confirmed Salmonella cases and 2 probable cases have been linked to sprouts consumption in New Zealand. Illness onset ranged from December 23, 2018 to April 1, 2019. 66 of the cases became ill between January 23, 2019 and January 25, 2019. 17 people required hospital treatment.
In the wake of the outbreak, GSF New Zealand recalled certain Pams, Sproutman, and Fresh Harvest brand sprout products. GSF New Zealand said the recall was due to a “production process concern.” Regarding the Salmonella outbreak, New Zealand’s Ministry of Health reported that “Salmonella Typhimurium phage type 108/170 was the causative pathogen identified from cases, sprouts and spent irrigation water tested in this outbreak. Subtyping using Multiple Locus Variable-Number Tandem Repeat Analysis (MLVA) and whole genome sequencing methods were performed on isolates to confirm cases in the outbreak as well as the outbreak source.”
The recalled sprouts had best before dates of March 31, 2019 to April 4, 2019.
