In April 2021, CDC, public health and regulatory officials in several states, and the US Food and Drug Administration investigated a multistate outbreak of Salmonella infections. Epidemiologic, laboratory, and traceback data showed that Jule's cashew brie was the source of the outbreak. This outbreak included people infected with one of four Salmonella serotypes: Chester, Duisburg, Typhimurium, and Urbana. A total of 20 sick people were reported from four states (Florida, California, Tennessee, and Maryland). Illnesses started on dates ranging from December 11, 2020 to May 9, 2021. Five people were hospitalized. There were not deaths.

Officials from California and Tennessee collected samples of Jule’s cashew brie for testing. WGS results showed that samples of Jule’s truffle cashew brie collected in both states were contaminated with Salmonella. California officials found the outbreak strains of Salmonella Chester and Urbana in the brie, and Tennessee officials found the outbreak strain of Salmonella Urbana. FDA and California Department of Public Health inspectors conducted an inspection at Jule’s Foods. FDA collected food and environmental samples from the facility and found the outbreak strain of Salmonella Urbana in samples of raw cashews. These raw cashews were from the same lot of cashews used to make the recalled brie. Other strains of Salmonella were found in the food and environmental samples, but these strains were not linked to any illnesses.

The outbreak was declared over on July 7, 2021.
