Background: Salmonella enterica subsp. enterica serovar Kentucky (antigenic formula 8,20:i:z6z₆) is a serovar of the O:8 (C₂-C₃) serogroup. In North America, serovar Kentucky remained the number one most prevalent serovar in poultry products. This serovar is commonly found in food animals in the U.S. (Chickenschickens, turkeys and cowscattle), but but rarely is reported in human cases. It is the most common serovar identified in non-clinical non-human sources, according to CDC, 2011. However, in Europe, serovar Kentucky is found in approx. 1% of the human cases (top 10).   A number of human cases have been reported in Europe in travelers from Asia and Africa. However, there are limited outbreaks with epidemiological investigation and clear source identification have been reported.

In the U.S., it is commonly found in animals (specifically cattle and poultry) and in meat. In Europe, Asia and Africa, this serovar is also regularly isolated from humans with symptoms consistent with salmonellosis.
