The Outbreak

By September 15th, the date of CDC’s initial outbreak investigation announcement, the number of cases had risen to 127 people from twenty-five states.

Déjà Vu
In the summer of 2020, the CDC and the Public Health Agency of Canada (PHAC) identifed a cross-border outbreak of Salmonella Newport infections that sickened more than 1100 people in 48 US states and 515 in seven Canadian provinces.
The source of the 2020 outbreak was traced to onions supplied by Thomson International Inc. of Bakersfield, California. Although, the outbreak strain was never recovered from Thomson’s onions, the FDA found eleven different Salmonella serotypes from various environmental samples.
