Key points
This outbreak is over. Learn what you can do to protect yourself from getting sick from Salmonella.
August 21, 2025
CDC, public health and regulatory officials in two states, and the U.S. Food and Drug Administration (FDA) investigated a multistate outbreak of Salmonella Oranienburg infections.
Epidemiologic and laboratory data showed that Emek-brand pistachio cream was contaminated with Salmonella Oranienburg and made people sick. As of August 21, 2025, this outbreak is over.
Epidemiologic Data
A total of four people infected with the outbreak strain of Salmonella Oranienburg were reported from two states. Illnesses started on dates ranging from March 10, 2025, to May 19, 2025. Of four people with information available, one was hospitalized, and no deaths were reported.
The true number of sick people in this outbreak was likely much higher than the number reported, and this outbreak may not have been limited to the states with known illnesses. This is because many people recover without medical care and are not tested for Salmonella.
Public health officials collected many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provided clues to help investigators identify the source of the outbreak.

State and local public health officials interviewed people about the foods they ate in the week before they got sick. Of the four people interviewed, all four (100%) reported eating pistachio cream. Three of the four people reported eating pistachio cream at the same restaurant.
Laboratory and Traceback Data
Public health investigators used the PulseNet system to identify illnesses that may be part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS).
WGS showed that bacteria from sick people's samples were closely related genetically. This suggests that people in this outbreak got sick from the same food.
The Minnesota Department of Agriculture collected and tested pistachio cream from the restaurant where sick people reported eating. WGS from these samples showed that the Salmonella in the pistachio cream was closely related to bacteria from the sick people, confirming the pistachio cream as the source of the outbreak.
In addition, FDA collected and tested import samples of Emek-brand products containing pistachio cream. Salmonella was detected in Emek Spread Pistachio Cacao Cream with Kadayif and Pistachio Cream samples. WGS revealed that the strain of Salmonella detected in the samples does not match the outbreak strain. Products that tested positive for Salmonella were not distributed and should not be available for sale.
WGS analysis of bacteria from four people's samples and five food samples predicted resistance to fosfomycin. More information is available at the National Antimicrobial Resistance Monitoring System (NARMS) site. Most people with Salmonella illness recover without antibiotics. However, if antibiotics were needed, this resistance is unlikely to have affected the choice of antibiotic used to treat illnesses in this outbreak.
Public Health Actions
On May 13, 2025, FDA and CDC issued an advisory for a 5-kilogram white tub of Emek-brand Pistachio Cream with a use-by date of October 19, 2026, and production code PNO: 241019. On July 14, 2025, World Market voluntarily recalled Emek Spread Pistachio Cacao Cream with Kadayif due to potential contamination with Salmonella. Both of these pistachio cream products are no longer available for sale.

Public health actions
On July 14, World Market voluntarily recalled Emek brand Pistachio Cream after testing identified Salmonella in the product. WGS is currently pending to see if it matches the outbreak strain.
No additional illnesses have been reported.
CDC, public health and regulatory officials in two states, and the U.S. Food and Drug Administration (FDA) are collecting different types of data to investigate a multistate outbreak of Salmonella Oranienburg infections.
Epidemiologic and laboratory data show that Emek-brand pistachio cream is contaminated with Salmonella Oranienburg and is making people sick. The investigation is ongoing to determine if additional lots or products are affected.
Epidemiologic data
As of June 13, 2025, four people infected with the outbreak strain of Salmonella Oranienburg have been reported from two states. Illnesses started on dates ranging from March 10, 2025, to May 19, 2025. Of four people with information available, one has been hospitalized and no deaths have been reported.
The true number of sick people in this outbreak is likely much higher than the number reported, and this outbreak may not be limited to the states with known illnesses. This is because many people recover without medical care and are not tested for Salmonella. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.
Public health officials collect many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provides clues to help investigators identify the source of the outbreak.

Public health actions
Retailers, restaurants, and distributors that purchased Emek-brand Pistachio Cream should not sell, serve, or distribute product with this lot number and production date while the investigation is ongoing.
