The Public Health Agency of Canada (PHAC) reports that there are now 110 people from five provinces who have been confirmed as outbreak patients. As of Dec. 21 there were 84 confirmed patients.
“Many of the individuals who became sick reported eating a variety of raw and cooked produce items before their illness. Initially, investigators identified that fresh avocados were reported by many cases before they became ill; however, more information was needed to confirm the source of the outbreak,” according to the PHAC outbreak update.
“As part of the food safety investigation, the CFIA collected different food items from restaurants where ill people dined. Testing found the outbreak strain of Salmonella in an unopened package of Alasko brand frozen whole kernel corn. Traceback findings identified Alasko as the common brand of frozen corn consumed at various foodservice establishments by individuals who became sick. Based on the investigation findings to date, the outbreak is linked to Alasko brand frozen whole kernel corn.”
Outbreak patients have been identified in five provinces: British Columbia with 42, Alberta with 49, Saskatchewan with 4, Manitoba with 13, and Ontario with 2. The illnesses reported in Ontario are related to travel to Alberta and British Columbia, according to the public health agency.
Patients documented so far became sick between early September 2021 and late December 2021. Four individuals have been hospitalized. No deaths have been reported. Individuals who became ill are between 1 and 89 years of age. The majority of cases, 64 percent, are female.
California officials found Salmonella in two unopened packages of Citterio brand Premium Italian-Style Salame Sticks that they collected for testing. WGS identified in these products a different strain of Salmonella (Salmonella Derby) that was not closely related to samples from sick people. PulseNet did not find any illnesses caused by this strain of Salmonella Derby.
Since the last update on October 29, 2021, 84 more sick people were added to this outbreak. As of November 12, 2021, 892 people infected with the outbreak strain of Salmonella Oranienburg have been reported from 38 states and Puerto Rico (see map). Illnesses started on dates ranging from May 31, 2021, to October 25, 2021 (see timeline).
The CDC reported a few moments ago that as of October 18, 2021, 652 people infected with the outbreak strain of Salmonella Oranienburg have been reported from 37 states. Illnesses started on dates ranging from May 31, 2021, to September 30, 2021.
FDA conducted a traceback investigation and identified ProSource Inc. as a common supplier of imported onions to many of the restaurants where sick people ate. One of these clusters occurred in a restaurant where investigators identified the outbreak strain of Salmonella Oranienburg in a condiment container with leftover lime and cilantro. The sick person reported that the condiment cup had also contained onions, although none were left when the condiment was tested. FDA is working to determine if other suppliers of onions may be linked to this outbreak or if there is a common supplier of onions in Chihuahua, Mexico.
A total of 36 people infected with the outbreak strain of Salmonella Enteritidis were reported from 11 states. The true number of sick people in an outbreak is likely much higher than the number reported, and the 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.
