It’s the source of an outbreak linked to tainted charcuterie, but what Salmonella I 4:I:-?
A strain by that name hasn’t been associated with any previous outbreaks, recalls, or illnesses, so it had us intrigued until the Minnesota Department of Health cleared up the mystery.
“This isn’t a new or different serotype but a change in laboratory methods. Since we now do serotyping using whole genome sequencing, 4 [5] 12:I:- is now reported as 4:I:-,” an epidemiologist in the Foodborne Unit explained.
Salmonella 4 [5] 12:I:- is a “monophasic variant of Salmonella Typhimurium, and it is an emerging threat to both human and animal health,” according to a recent study. Contaminated feed is considered the primary vehicle, researchers found.
The strain has caused several recent food poisoning outbreaks linked to pork and chicken.
