Outbreaks of foodborne Salmonella Enteritidis in The United States 1990-2015

International Journal of Infectious Diseases - 2021 25 February, 2021

A new study analyzed the data of all Salmonella Enteritidis (SE) outbreaks reported to the Centers for Disease Control and Prevention (CDC) from 1990 to 2015.
In the USA, from 1990-2015, there were 1144 single-state SE outbreaks reported to CDC. Of 1144 SE outbreaks, 657 (57%) were reported with known food items, and 487 (43%) were unknown source-based outbreaks. Of 657 known food source outbreaks, 273 (24%) were associated with egg-based products and ranked as the leading cause of SE outbreaks cumulatively from 1990 to 2015. Meat products were the next most common cause of SE outbreaks (130, 11%) followed by vegetables (96, 8%), chicken (95, 8%), dairy products (55, 5%), and bakery items (8, 1%). the highest number of outbreaks were reported in 1990 (88, 8%) followed by 1991 (74, 7%) and 1993 (69, 6%).
Egg-associated outbreaks were dominantly higher than other known food sources until 2005. Afterward, other food sources, i.e., meat, chicken, vegetables, caused more SE outbreaks or at a similar rate as eggs in the country. The number of chicken-associated outbreaks have been increasing from 2009 to 2015.
Overall, the highest number of SE outbreaks (645, 56%) occurred at restaurants followed by private residences (190, 17%), institutions (84, 7%) and healthcare facilities and healthcare facilities (65, 6%).
