Salmonella vaccines are a proven, pre-harvest intervention to reduce the overall prevalence of Salmonella contamination of birds entering the processing facility, especially the higher-risk Salmonella B and D serotypes. Now, the Centers for Disease Control and Prevention (CDC) is encouraging the poultry industry to expand the use of Salmonella vaccines to help control Salmonella in poultry flocks.
According to the CDC’s latest Morbidity and Mortality Weekly Report, researchers from the CDC’s Foodborne Diseases Active Surveillance Network (FoodNet) found that human food-borne illness incidents caused by S. enteritidis held steady last year, while S. typhimurium incidents declined by 13% compared to data collected from 2016-2018.
