Salmonella in Canada

Canada Communicable Disease Report (CCDR) 16 July, 2021

A new study shows that of the 96,082 Salmonella cases reported to the National Enteric Surveillance Program (NESP) in Canada during the 14-year study period,4.4% were bacteremic. Patients with bacteremia are more likely to experience severe outcomes, including hospitalization and death, unless treated promptly with antibiotics.  19 nontyphoidal Salmonella (NTS) serovars were identified as having higher rates of bacteremia. Of the 570 NTS serovars reported to the NESP from 2006 to2019, 136 were associated with bacteremia. Enteritidis was the most frequently associated with bacteremia, with over 1,000 reports. With Heidelberg, these two serovars accounted for 60% of the blood reports. Typhimurium, Dublin and Oranienburg were, respectively, the third, fourth and fifth most frequently serovars reported in blood. Heidelberg, Oranienburg, Schwarzengrund, Virchow, Panama and Poona among the top 25 most commonly reported serovars in Canada during the study period.
