There are three current multistate outbreaks of Salmonella in the United States. Two–infections linked to Butterball Brand Ground Turkey and Precut melons–are outbreaks that began in 2019 and the third involving ground turkey was a 2018 outbreak of raw ground turkey products that remain open.
Taken together, the three have sickened 279 people resulting in 107 hospitalizations and one death. One or the other of these outbreaks has spread the Salmonella infections to nearly every one of the 50 states.
How were these outbreaks possibly made worse?
It can happen, according to Yaohui Sun and Alex Mogilner of New York University. Salmonella bacteria can “flip an electric switch” as they catch a ride inside immune cells, causing migration out of the gut to invade other parts of the body.
