On October 20, 2023, health officials in the County of San Diego, California, put out a press release warning of a Salmonella outbreak linked to raw (unpasteurized) milk. Such an outbreak is not particularly surprising; the reason the vast majority of milk is pasteurized (heated briefly to kill germs) is because milk can easily pick up nasty pathogens in the farmyard that can cause severe illnesses, particularly in children. It’s the reason public health officials have long and strongly warned against consuming raw milk.
At the time of the press release, officials in San Diego County had identified nine residents who had been sickened in the outbreak. Of those nine, three were children, and all three children had been hospitalized.
On October 25, the county put out a second press release, reporting that the local case count had risen to 12, and the suspected culprit—raw milk and raw cream from Raw Farm LLC—had been recalled. The same day, Orange County’s health department put out its own press release, reporting seven cases among its residents, including one in a 1-year-old infant.
