As of September 14, 2020, there have been 515 confirmed cases of Salmonella Newport illness linked to this outbreak in Canada. The following provinces have reported cases: British Columbia (121), Alberta (293), Saskatchewan (35), Manitoba (26), Ontario (14), Quebec (25) and Prince Edward Island (1).

Whole-genome sequencing analysis shows that an outbreak of Salmonella Newport infections in Canada was related genetically to this outbreak in the United States. This means that people in both of these outbreaks were likely to share a common source of infection. Their investigation identified red onions from Thomson International Inc. as the likely source of their outbreak.

In the United States, thirty-four illness clusters were identified in 13 states. Information was collected on 23 of the 34 clusters at restaurants and grocery stores. The traceback information collected from several of these illness clusters identified Thomson International, Inc., of Bakersfield, California, as a likely source of red onions. Due to the way onions are grown and harvested, other onion types, such as white, yellow, or sweet yellow, are also likely to be contaminated.

On August 1, 2020, Thomson International, Inc., voluntarily recalled red, yellow, white, and sweet yellow onions because they may be contaminated with Salmonella. Several other companies also recalled the tainted onions. See the full list of the recalled products on the CDC site.

On August 5, 2020, the United States Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) issued a public health alert for products made with recalled onions. Check the alert for product details.

On August 6, 2020, Taylor Farms issued a recall of foods that were made from recalled onions.

As of October 8, 2020, this outbreak appears to be over. The FDA is continuing its investigation to find the root cause of the outbreak. Consumers, restaurants, and retailers should not eat, serve, or sell recalled onions from Thomson International, Inc., of Bakersfield, California, or other foods made with recalled onions.

Symptoms of a Salmonella infection, called salmonellosis, typically start 6 to 72 hours after exposure to Salmonella bacteria from an infected animal, person or contaminated product. Symptoms include:

  • chills
  • fever
  • diarrhea
  • abdominal cramps
  • headache
  • nausea
  • vomiting

These symptoms usually last for 4 to 7 days. In healthy people, salmonellosis often clears up without treatment, but sometimes antibiotics may be required. In some cases, a severe illness may occur, and hospitalization may be required.
