Salmonella-in-Diced-Onion Outbreak Over, Investigation Finds Salmonella at Farm

CDC declared the Salmonella outbreak associated with diced onions is now over. The onion product produced in August by Gill Onions of Oxnard CA, has cased 80 illnesses with 18 hospitalizations and 1 death. The product was recalled in October.

 "FDA collected multiple water, environmental, and product samples from the farm that supplied the contaminated onions to Gills Onions. Six of the samples, three water and three environmental, were positive for Salmonella spp. Whole Genome Sequencing (WGS) analysis confirmed that the strain of Salmonella found in isolates associated with three of the samples matched the same strain of Salmonella causing illnesses in this outbreak. Additional Salmonella isolates from the samples were detected, and CDC identified people who got sick with these strains of Salmonella. FDA and CDC partners reviewed the available data; however, there was not enough epidemiologic or traceback evidence to implicate a product or source of contamination for those illnesses."

The FDA and CDC, in collaboration with state and local partners, investigated an outbreak of Salmonella infections linked to recalled diced onions under the Gills Onions brand name.

As part of this investigation, FDA collected multiple water, environmental, and product samples from the farm that supplied the contaminated onions to Gills Onions. Six of the samples, three water and three environmental, were positive for Salmonella spp. Whole Genome Sequencing (WGS) analysis confirmed that the strain of Salmonella found in isolates associated with three of the samples matched the same strain of Salmonella causing illnesses in this outbreak. Additional Salmonella isolates from the samples were detected, and CDC identified people who got sick with these strains of Salmonella. FDA and CDC partners reviewed the available data; however, there was not enough epidemiologic or traceback evidence to implicate a product or source of contamination for those illnesses.

As of December 4, 2023, CDC announced that the outbreak is over. CDC reports a total of 80 illnesses in 23 states. There has been a total of 18 hospitalizations and one death associated with this incident. The last illness onset was November 11, 2023. FDA’s investigation is complete.
